1.0 EXECUTIVE SUMMARY
1.1 Introduction
The objective of this Transitional Asset Management Plan (AMP) is to outline the asset management practices and strategies used to manage the assets of GasNet Limited (GasNet) and to provide such information pursuant to the transitional provisions provided for GasNet under clause 2.12.8 the Gas Distribution Business Information Disclosure Determination 2012.
This AMP, being the third produced by GasNet and prepared under transitional provisions, has been prepared to satisfy the new regulatory requirements as a minimum, and as such does not necessarily provide the comprehensive information typically found in mature Asset Management Plans. Following the approval and publication of this AMP GasNet will continue to build on this platform through accelerated continual improvement of its asset management practices and documentation, evidenced through subsequent AMP publications until ultimately meeting the requirements of a fully compliant Asset Management Plan by 30 September 2017 being the end of the first regulatory period.
GasNet has a long history of in-practice asset management with limited longer term planning processes. It has operated asset management practices that while effective, comprise a combination of formal and informal documentation. GasNet is however in a relatively unique position in that because there has been very low personnel turn-over, it has a wealth of very long term engineering and operational experience within personnel reaching back some 30 years. GasNet has effectively managed network assets in accordance with gas industry standards, good practice and procedures, and reported compliance over an extensive period of time.
Whilst GasNet has long since recognised the value to its business of formalising and collating its asset management strategies, policies, and procedures through the development of a single AMP document, it has been reluctant during an extensive period of regulatory uncertainty over the last 5-6 years, to commit the significant labour and financial resources to develop an AMP until the specific regulatory requirements were known.
The Commerce Commission recognised that GasNet had not historically been required under information disclosure regulation to publicly disclose an Asset Management Plan, and consequently made additional transitional provisions within its Gas Distribution Information Disclosure Determination 2012 (IDD) that allowed GasNet to elect to publicly disclose a Transitional Asset Management Plan as an alternative to a fully compliant Asset Management Plan.
In consideration of the resourcing needs to develop its first Asset Management Plan and that the requirement to do so was only one of many new regulatory compliance requirements that GasNet needed to meet in 2013 (including the unrelated certification of its Safety Management System for Public Safety), GasNet elected to adopt the transitional provisions and deliver this Transitional Asset Management Plan (AMP)
Therefore in accordance with the transitional provisions specified under clause 2.12.8 of the IDD and copied to Appendix 1, the information contained within this AMP has been provided to satisfy the following:
Minimum Requirements (IDD clause 2.12.8(2)(c));
Forecast Information (IDD clause 2.12.8(2)(d));
Report on Asset Management Maturity (IDD clause 2.12.8(2)(e));
Identified non-conformances and intended actions to make compliant by end of first DPP regulatory period (IDD clause 2.12.8(2)(f)); and,
Identified actions taken to achieve conformances with the requirements of a fully compliant Asset Management Plan (IDD clause 2.12.8(2)(g)).
1.2 Reference to AMP
For ease of reference this Transitional Asset Management Plan is referred to throughout this document as an AMP. However it must be noted that whilst referred as such it does not imply, nor is it promoted to be, a fully functional and informative Asset Management Plan. It has been prepared to comply with the transitional provisions afforded to GasNet under the Gas Distribution Business Information Disclosure Determination 2012 and not necessarily to comply with the International Infrastructure Management Manual (IIMM), PAS-55, or any other applicable standard.
1.3 Effective Date of Data in AMP
Except where otherwise specified data contained within this AMP, typically shown in tables and graphs, is based on that which existed as at 30 June 2014.

2.0 BACKGROUND AND OBJECTIVES
2.1 Company Background
GasNet is 100% owned by Wanganui Gas Limited which is itself owned by Wanganui District Council Holdings Limited, a Wanganui District Council “Council Controlled Trading Organisation”. GasNet commenced trading on 1 July 2008 after purchasing the network (and metering) business from Wanganui Gas Limited. Previously GasNet had been operating as an independent trading division of Wanganui Gas Limited with responsibility for managing the network (and metering) assets for the company.
GasNet’s origins go back to the late 19th century when in 1879 Wanganui Gas Company Limited was formed as a private enterprise to reticulate manufactured gas within the city of Wanganui. All networks owned and operated by GasNet have been constructed to natural gas standards since 1970.
2.2 Gas Distribution Business
GasNet owns and operates five natural gas distribution networks in the Wanganui, Rangitikei and South Taranaki regions in the North Island of New Zealand.
In accordance with the Gas Act 1992, GasNet is defined as a “Gas Distributor” and under the IDD is a Gas Distribution Business (GDB).
2.3 Details on AMP Planning Period
The AMP planning period is 1 July 2015 to 30 June 2025.
2.4 Date Approved by Directors
GasNet’s Board of Directors formally approved this AMP on 6 July 2015.
2.5 Stakeholder Interests
Stakeholder interests are considered within GasNet’s asset management practices and whilst they may not always be in alignment, the desire to provide a reliable gas supply is generally common to all.
GasNet’s asset management practices implicitly acknowledge the diversity of interests and their frequency of occurrence. They are reviewed and modified over time in response to feedback from stakeholders, change in legal and/or regulatory requirements, and identified organisational practice improvement.
It is recognised that on occasion stakeholder interests either are or appear to be in conflict. GasNet welcomes the opportunity to discuss with the stakeholder any situations where interests may conflict, and will at all times look for outcomes that are mutually acceptable. Where such outcomes are not possible, GasNet offers a “Feedback & Complaints” process that provides for investigation of the reported issue within a defined process and timeframe. In the event that a satisfactory solution cannot be agreed upon, either party may refer the dispute to the Electricity and Gas Complaints Commission.
Whilst the occurrence of conflict with, or between, the needs of stakeholders seldom occurs, GasNet will apply the following considerations in resolving conflict:
Safety of people and property
Reliability of the gas supply
Compliance with the law, industry standards and codes
Fairness and equity to all parties
Regulatory compliance
GasNet has identified the following stakeholders as having an interest in how GasNet manages its gas distribution assets:

GasNet engages with its stakeholders by a wide range of methods, both planned and ad hoc. One key area of interest on which GasNet has not proactively sought feedback, is with its consumers. Whilst GasNet has regular contact with consumers, for a variety of reasons in the course of operating and maintaining its assets, it has not actively pursued contact, leaving this to the consumer’s retailer who in most instances insists on managing the relationship with their customer. With requirements under the new regulatory regime to provide more information to consumers and in recognising the potential value from proactive engagement, GasNet plans to work with the retailers on how GasNet goes about engaging with the consumers to achieve the desired outcome without overly burdening or confusing them.
2.6 Organisational Structure
GasNet’s organisational structure is as shown below.

2.8 Asset Management Policy
GasNet’s Asset Management Policy was reviewed in early 2014 and a new policy document approved by the Board of Directors at its meeting on 24 June 2014. In the formulation of the new policy it was decided to adopt the Publicly Available Specification on Asset Management (PAS 55:2008) as the guiding standard given its widespread acceptance and its close alignment with the IDD regulatory requirements. Up until the introduction of the new policy the International Infrastructure Management Manual (IIMM) had been the primary reference standard.
As the new Asset Management Policy was not approved until late June 2014 the Report on Asset Management Maturity (AMMAT) shown in Appendix 3.1, states that the International Infrastructure Management Manual (IIMM) is the “Asset Management Standard Applied” as this was the standard which applied for all but a few days leading up to 30 June 2014 when this AMP was approved and published.
2.9 Strategy and Delivery
Whilst GasNet has yet to develop a formal documented AMP Strategy the absence of such a document should not reflect on the lack of strategic direction, with tangible evidence illustrated throughout the organisation and its documentation. There are many examples of strategies both past and present that GasNet has implemented (some of which are described in this AMP), typically spanning a number of years that relate to the strategic management of its network assets.
As an example, the most recent and significant strategy which has only just been completed, was the decision in 2005 to relocate all LP service pipes where the GMS was located within the building. Dating back to the manufactured gas era it was typical for services to be installed under the house to a meter position in a cupboard, usually in the kitchen, hallway or porch. GasNet having undertaken a risk analysis at the time, identified that these metallic low pressure services posed the greatest risk and opportunity for gas to enter buildings, especially as

General Manager
many of these pipes were bare steel and laid either on or just under the ground. The strategy was approved by the Board of Directors and recognising the nature of the issue it took an active interest in seeing it through to its conclusion. Since 2005, 639 services have been relocated such that no part of the service pipe passes under the building line.
GasNet recognises the value and benefit in centralising its strategies into one document and had planned to complete this task in parallel with the review of its Asset Management Policy in the last quarter of 2013, however whilst the policy has been approved and implemented, the strategic plan will now not be completed until later in 2015.
2.10 Overview of Systems and Data
GasNet’s information systems are extensive both in terms of hardware and software applications.
Each GasNet employee is assigned a PC; a desktop for office based personnel and either a tablet or Toughbook device with remote access for field based personnel. All are connected to GasNet’s IT network which is provided under a Service Level Agreement (SLA) with the Wanganui District Council (WDC). Under the terms of the SLA the WDC provide the following hardware and software support services:
Hardware Support
All infrastructure hardware up to and including the hub at the GasNet building
Data storage and retrieval
Printing to network printers
Internal and external email access
Internet access
Data and file access security
Physical server and data security
Network infrastructure maintenance
File and data backup and recovery
VPN access for remote working
Software Support
Microsoft suite of applications (Windows, Office Suite, Project, Visio, Internet Explorer, Publisher)
Finance One
ANZ Online Banking (software)
Payglobal
Web Marshal
Virus protection
The WDC has provided IT network services to GasNet, and its predecessor and now shareholder Wanganui Gas Limited, for decades in a mutually beneficial arrangement, with the WDC as the “ultimate owner” having an interest in the Company and GasNet’s need for IT services. The arrangement is a good fit for GasNet and provides access to services it may otherwise be unable to obtain, or that may not be cost effective for a smaller operation such as GasNet.
Based on this platform and with an extensive suite of software applications in current use GasNet considers it is well placed to provide the ever increasing demand for information, particularly in light of the new regulatory regime under which this AMP has been developed. Whilst GasNet is not presently able to provide the full suite of information required, or must extensively aggregate/disaggregate information currently held to satisfy the information requirements, it is nevertheless confident that by the end of the first regulatory period it will meet the requirements of a fully compliant Asset Management Plan.
The following table provides a summary of the main software applications currently in use.

In addition to a wealth of information contained within the various applications and databases referred to above, GasNet has an extension range of MS Excel spreadsheets and one MS Access database. Whilst ideally all data should be held within a managed software application, there are many instances where it is not cost effective to do so, typically due to the infrequency of use or the amount of information/data being held.
GasNet recognises that the IDD significantly increases the level of data capture, information management and disclosure, but considers itself well placed to ensure that during the balance of the initial regulatory period the requirements will be fully integrated into GasNet’s information technology environment.
2.11 Overview of Asset Management Documentation, Controls and Review Processes
Much of GasNet’s asset management documentation is integrated within other documentation and consequently there are few asset management specific documents. The recent certification of GasNet’s Public Safety Management System (PSMS) is an example where the opportunity was taken to integrate asset management with the documentation developed for the safety management system, particularly relevant given many of the synergies between the requirements. The Risk Management Policy is a generic document encompassing all risks the Company either is or may be exposed to, as shown in the comprehensive risk matrix contained within the Policy.
With the rate that GasNet has recently developed documentation both in respect of its PSMS and asset management, the strategy has been to continue producing the required documents rather than reviewing existing documentation that may be due for review. Whilst not desirable, this approach has been necessary to ensure the required systems are in place within a reasonable time period.
With the significant increase in documentation over recent years it has been essential to ensure documents are subject to a control regime that guarantees the latest version of any document is available to those that need it, and also that it is clear which documents are in draft and which have been superseded. GasNet’s Intranet has provided the primary access point for key GasNet documentation, with the latest versions once approved being posted on the site. In addition a suite of Registers, also available on the Intranet, provides the master list of documents and their status. A more robust form of document version control has been introduced, appropriately at the time the Policy Framework Policy was approved and introduced in January 2013, so that as each document is subject to its next review the version control will be applied.

3.0 OVERVIEW OF ASSETS
GasNet’s origins go back to the reticulation of manufactured gas within the city of Wanganui. Over the following decades as the city developed and grew so too did the gas infrastructure until the availability of natural gas in the late 1960’s displaced the need for manufactured gas. Although much of the original infrastructure has been replaced, there still remains approximately 48 km of low pressure metallic mains in operation and subject of an on-going mains replacement activity. All networks owned and operated by GasNet have been constructed to natural gas standards since 1970.
3.1 Gas Distribution Networks
3.1.1 Networks
GasNet owns and operates five discrete natural gas networks as shown below. Each network is connected by a Sales Gate station to the Vector Limited owned transmission pipeline. The five networks are known as Wanganui, Marton, Bulls, Waitotara, and Flockhouse.
Figure 1: Network Locations
Each GasNet network begins at the designated outlet of each Sales Gate station and labelled ‘custody transfer’ point. Natural gas is transported through a combination of metallic and polyethylene pipes in the GasNet network, typically reducing in pressure to the consumer’s property. The outlet of the gas service valve at a consumer’s property represents the end of the network and the ‘demarcation point’ between network and Gas Measurement System (GMS) assets.
Figure 2 shows the configuration of a typical gas network indicating the demarcation points, the means of supplying gas at various pressures to industrial, commercial, and residential users, and the equipment required to operate the network.

Figure 2: General Network Layout
3.1.2 Network Assets
Each network comprises assets categorised as mains and services, district regulator stations, valves, and crossings, interconnected in a layout similar to that shown in Figure 2 above.
3.1.2.1 Mains
Mains are larger sized pipes which are used to transport volumes of gas from one point on the network to another for further distribution and use. They are principally installed underground, are constructed of either metallic or polyethylene material, and transport gas at intermediate (IP), medium (MP), and low (LP) pressures.
IP mains are all steel construction while MP mains are generally constructed of polyethylene material. LP mains are a mix of materials including polyethylene and various metallic materials (welded or riveted steels, and cast or wrought irons).
3.1.2.2 Services
Services are smaller sized pipes which are used to transport volumes of gas from a main to a GMS installed typically on the consumer’s property. Services are principally installed underground, are constructed of either metallic or polyethylene material, and transport gas at intermediate (IP), medium (MP), and low (LP) pressures.
IP services are all steel construction while MP services are generally constructed of polyethylene material. LP services are a mix of materials including polyethylene and various metallic materials.
3.1.2.3 District Regulator Stations (DRS)
District Regulator Stations reduce and regulate the gas to suitable pressures to enable distribution across large areas. DRS are generally constructed of steel components and reduce pressures from IP to MP and/or LP, and MP to LP pressures. The district regulator stations are categorised as DRS or mini DRS. Mini DRS generally supply only a limited number of consumers and are typically installed where the main fronting the properties is not suitable for individual service connections.
3.1.2.4 Main Line Valves (MLV)
Main line valves are installed in strategic locations to allow isolation of sections of the network for public safety in the event of an emergency, to isolate specific network assets such as DRS, to facilitate maintenance, or to allow further connection. MLVs are installed underground and in most cases are accessed via a chamber and lid through which a valve key may be inserted to operate the valve. There are three types of MLV: Polyethylene ball valves, flanged steel ball valves, and flanged steel or iron plug valves.
3.1.2.5 Crossings
A Crossing refers to any section of main or service that passes under or over an area of special interest that has a different risk profile to that of other mains or services located in areas of a more general nature. Crossings include all mains that pass under railway lines or over rivers and streams, are mounted on bridge superstructures, or otherwise supported above the ground.

3.1.2.6 Corrosion Prevention
A range of proprietary coating systems provide the primary means of protecting steel pipes and fittings from corrosion both above and below ground.
A secondary protection system for all underground IP and MP steel mains and services, known as Cathodic Protection (CP), is also installed which uses either an impressed current system, sacrificial anode system, or combination of both. Monitoring test points are positioned at strategic locations along the mains and at District Regulator Stations to enable measurement of the level of protection at that location. Routine CP monitoring checks are performed to confirm adequate levels of protection are maintained.
3.1.2.7 Monitoring and Control Systems
At various strategic locations across the IP, MP, and LP networks, Monitoring and Control Systems are installed to monitor and record network data. Generally a Monitoring and Control System utilises modem and internet connection to transmit time stamped data to a central collection point for analysis. Typically the Monitoring and Control System has the ability to transmit network alarms real time to operational personnel for action.
In addition to pressure and voltage Monitoring and Control Systems, GasNet has included in this asset category its one Network Metering Station located in Wanganui that is used to measure all gas entering a discrete area of residential housing. The Network Metering Station consists of a meter, associated data capture device, remote access telemetry and necessary valving, pipe work, etc.
Information captured from all Monitoring and Control System units can also be used in throughput modelling, consumption predictions, and as a valuable input to network design.

3.1.4 Asset Age Profiles
The following profiles are extracted from the most recent data sets available at the time of preparing this AMP. Assets which pre-date natural gas are populated with a default date of 1956 since identifying installation and commissioning dates for assets of that era has proven problematic due to insufficient records.
In respect of data accuracy for the pipe assets (mains, services, and crossings) it is judged that 50% of the installation dates are based on known information, while 50% are unconfirmed and based on assumptions made from other related records, or determined by a suite of rules.
In many instances the service pipe to a consumer’s premise comprises multiple sections of pipe that are not necessarily of the same installation date. The age profile then for services reflects the length of each service pipe component, rather than the number of services.

4.1 Wanganui Network
The Wanganui network transports natural gas at intermediate (IP), medium (MP), and low (LP) pressures. Figure 3 is illustrative of the configuration, specification and operating parameters of this network.
Figure 3: Wanganui Network Configuration
4.1.1 Intermediate Pressure (IP) System
The IP system shown in Figure 4 below is generally designed as a single arterial pipeline from the Sales Gate station to Castlecliff in the west and to Aramoho in the north, with reinforcement looping of the industrial areas. It is currently operating at 1050 kPag.
The system was originally designed to supply major industrial consumers and DRS were located at points along the pipeline matching adverse demand requirements. As looping of system sections exists to reinforce industrial demands, the balance of the system is reliant on the integrity of these sections of the IP mains to provide continuous supply.

4.1.1.2 IP Mains
The IP mains are constructed of steel API line pipe coated with yellow coloured polyethylene material (known as yellow jacket pipe). The steel pipe is weld jointed at 6 or 12 metre intervals, and terminates at stations or other equipment with welded flanges. The IP mains are generally installed underground by open trenching method and are fully electrically insulated.
In Figure 4, the IP mains are shown as a black line. The Wanganui Sales Gate station is shown as “SG1”.
Figure 4: Wanganui Intermediate Pressure System
Following the introduction of natural gas to Wanganui in 1973, the IP system was constructed. Reinforcement looping of the network was constructed in the early 1980s during a period of significant network growth.
4.1.1.3 IP Services
The IP services are connected to mains with a variety of connections and terminate above ground with a welded flange. All IP services are electrically insulated and isolated from the main and from the GMS.
4.1.1.4 IP District Regulator Stations (DRS)
DRS configurations include twin stream active/monitor regulation, single or twin stream active/monitor, worker/standby stream, and single stream worker only. The mini DRS are generally configured as single stream worker only.
In Figure 5, DRS are shown prefixed with a “D” and the smaller mini DRS with “MD”. The Sales Gate station is shown as “SG1”. Each location is marked with an icon.

4.1.1.5 IP Main Line Valves (MLV)
MLVs are used to split sections of looped network, isolate strategic assets such as crossings and DRS, and isolate branch connections off the main arterial pipeline. MLVs are located principally underground, in pits or chambers that are accessible from the surface for insertion of valve keys to enable their operation. IP MLVs are flanged ball or plug types constructed of steel or iron material.
4.1.1.6 IP Crossings
Crossing types include bridge, stream, aboveground and rail. Each type of crossing is constructed to meet the individual specific risk profile of the environment in which the gas asset is crossing. IP crossing construction can include casing and vents, roller support mounts, thermal expansion joints, and other specialist fittings.
In Figure 6, bridge crossings are shown prefixed with “BC”, stream crossings with “SC”; above ground crossings with “AG”, and rail crossings with “RC”.
Figure 6: Wanganui Intermediate Pressure Crossings
4.1.1.7 IP Corrosion Prevention
The Wanganui Cathodic Protection system comprises a combination of impressed current and sacrificial anode systems. The IP mains constructed in the 1970’s when natural gas was first introduced to Wanganui were protected by sacrificial anodes installed at regular intervals along the buried steel mains, each with its own test point at ground level for monitoring purposes.
In the mid 1980’s a new impressed current system was installed adjacent to the Sales Gate comprising a rectifier supplied from the local electricity network and a sacrificial anode bed installed in the Whanganui River bed. Whilst for a variety of reasons a number of the original sacrificial anodes have been permanently disconnected from the system over the years, a number still remain in service operating in conjunction with the impressed current system.
In Figure 7, cathodic protection monitoring test points are shown prefixed with “CP” and the IP mains shown as a black line.

4.1.1.8 IP Monitoring and Control Systems
IP monitoring is a part of the wider network electronic pressure and CP monitoring system. Operational conditions are monitored at various points on the IP system and data is sent to a central monitoring station daily. The equipment is configured to monitor for critical minimum IP system parameters and activate alarms which are transmitted to monitoring software that notifies operational personnel. GasNet has installed pressure monitoring telemetry at a number of large demand sites.
4.1.2 Medium Pressure (MP) System
The MP system shown in Figure 8. below is generally designed in a grid configuration with mains connected wherever pipes cross. The system is constructed predominantly of polyethylene with four sections of API steel, being designed with a maximum allowable operating pressure of 420 kPag and is operating at 210 kPag.
Construction of the MP system commenced in 1977 with API steel mains installed between DRS. Further development of the MP system brought the benefits of higher pressure distribution. Much of the MP system has been constructed by inserting the newer PE pipe into the older (pre natural gas) metallic pipes.
In 1989 a decision was taken to cease refurbishment (reconditioning) of LP metallic mains and instead insert them with polyethylene pipe and thereby be able to increase the operating pressure to MP. Alternatively GasNet would replace them with polyethylene pipe of the same size and continue to operate them at LP.

4.1.2.2 MP Mains
The gas mains are almost entirely constructed of Polyethylene pipe with a small amount of API line pipe coated with yellow jacket. The first polyethylene pipe installed was high density polyethylene, (HDPE) and it continued to be installed until the introduction of medium density polyethylene (MDPE). Thereafter all further construction used MDPE as this proved to be a more durable pipe material.
In Figure 8, the MP mains are shown as a black line. The Sales Gate station is shown as “SG1”. Some lengths of MP mains appear separated from the bulk of the mains as they are fed from a mini-DRS (not shown).

4.1.3.2 LP Mains
With the introduction of polyethylene pipe, rehabilitation projects began replacing the metal mains and services with PE. Network development plans of the time were to construct new polyethylene mains and services to medium pressure construction standards but remain on low pressure and when significant areas had been completed, to up-rate the operating pressure to medium pressures.
In the early 1990s GasNet embarked on a project involving insertion of the original larger diameter LP mains and services with smaller diameter PE pipes. The immediate benefits of the higher (MP) pressure were realised and

the cost of construction was reduced. This method became the favoured method for future mains rehabilitation for the areas where MP was available and it could be completed without compromising the LP network.
In Figure 12, the LP mains are shown as a black line. The Sales Gate station is shown as “SG1”. Some lengths of LP mains appear separated from the bulk of the mains as they are fed from a mini-DRS (not shown).
Figure 12: Wanganui Low Pressure System
Older, pre-natural gas LP mains were constructed of a variety of metallic materials such as cast and wrought irons and various steels manufactured in lengths from 9 feet to 30 feet depending on the material. These LP mains were installed to levels that allowed condensates within the coal gas to drain to a low point where a siphon was installed to collect the liquid which could later be pumped out. The mains were all mechanically jointed using the bell and spigot method for cast iron mains and compression couplings for other types.
LP cast iron pipes are generally in reasonable condition for their age, with many pipe to pipe joints having been encapsulated over the years to prevent leakage. An extensive programme of joint encapsulation was undertaken immediately following the introduction of the dry natural gas to the manufactured gas network in the early 1970’s, with initial leakage reported at 82% UFG (Unaccounted for Gas). The bell and spigot joints on the cast iron mains contained a hemp seal which relied on the wet manufactured gas to keep the joint gas tight. The unfortunate consequence of introducing the dry natural gas was that many of the joints dried out and with pipe sections being typically around 3m in length, leakage became a significant issue until it came under control a few years later. Joint leakage is less of a concern nowadays and whilst it does occur from time to time, it does not prevent the safe on-going operation of the LP cast iron network.
The other LP pre-natural gas metallic mains comprise a range of unwrapped bare steel, galvanised and wrought iron materials which are in a range of conditions and are being progressively replaced.

4.3.1.2 MP Mains
The Bulls MP system shown in Figure 22. was installed to supply consumers in Bulls township including a CNG station. The design incorporates a single arterial main constructed in 1987 which was installed from the Sales Gate station at Lake Alice, traversing rural land to the west side of Bulls township. The network is supplied direct from the Sales Gate with no District Regulator Stations (DRS). The main has a design maximum allowable pressure of 420 kPag which is operating at 300 kPag. The network within the township is generally designed with arterial mains having little interconnection. The development of a meat processing plant on the outskirts of Bulls has replaced the CNG load.
In Figure 22, the MP mains are shown as a black line. The Sales Gate station is shown as “SG4”.

4.3.1.6 MP Monitoring and Control Systems
MP monitoring is a part of the wider network electronic pressure monitoring system. Operational conditions are monitored at various points on the MP system and data is sent to a central monitoring station daily. The equipment is configured to monitor for critical minimum MP system parameters and activate alarms which are transmitted to monitoring software that notifies operational personnel. GasNet has installed pressure alarm monitoring at a number of large demand sites.
4.4 Flockhouse Network
The Flockhouse MP network was primarily installed to supply a large agricultural training centre and grain dryer, with both domestic and commercial connections offered to properties along the pipe route. The network is supplied direct from the Sales Gate at MP with no DRS connected.
Figure 24 is illustrative of the configuration, specification and operating parameters of this network.

5.0 SERVICE LEVELS
5.1 Key Performance Indicators (KPI’s)
GasNet has actively collected a range of performance statistics for many years, some of which having been reported under previous disclosures, and whilst the content of what will be reported in future AMP’s has yet to be finalised, the graphs are provided in the interim.
For consistency all tables cover the four years up until 30 June 2013 but a number of the datasets include both Network and GMS data, a legacy of the Company’s previous reporting requirements and the requirements under the now superseded Gas Information Disclosure Regulations 1997. Whilst some datasets are clearly network only, others are not. It is therefore planned to disaggregate the combined datasets wherever practical to do so and include them in future AMP publications.
Network performance for previous years, for both planned and unplanned outages, are shown in the following graphs. The key indicators used are those now required under the IDD and include:
System Average Interruption Duration Index (SAIDI) in minutes per consumer;
System Average Interruption Frequency Index (SAIFI) in outages per consumer;
Customer Average Interruption Duration Index (CAIDI) in minutes per outage.
The data shown applies only to outages caused by failures or planned outages on GasNet’s network and does not include outages caused by the Transmission Company or other upstream parties.
In simple terms SAIDI is a measure of how long the average consumer has been without their gas supply during a particular year.
The high duration of unplanned outages which occurred in 2009/10 and which also flowed through to the beginning of the 2010/11 year was attributed to a single incident in late June 2009 which occurred in St Johns Hill, Wanganui, where a metallic steel water service failed due to corrosion and subsequently eroded an adjacent Low Pressure gas service pipe, eventually causing failure of the gas service pipe. As the water pressure was much greater than the gas pressure, water flowed relatively freely into the pipe until it built up within the Low Pressure gas network causing complete loss of gas supply to consumers within the area. Over the following days after the leaking water service was discovered and repaired, the network was isolated in sections and the water purged out of the pipes.
The subsequent years 2011/12 and 2012/13 are more representative of the typical duration associated with unplanned outages.
In respect of the planned outages, the marked and continual increase is due to a combination of the on-going improvement in data collection methods and an increase in the type and nature of work being performed on the network to improve the consumers supply.

General Manager
In simple terms SAIFI is a measure of the number of times a consumer will experience an interruption to their gas supply during a particular year.
For the reasons outlined above under SAIDI, the high number of unplanned outages which occurred in the 2009/10 and 2010/11 years was dominated by the St Johns Hill water ingress incident which occurred in late June 2009.
In simple terms CAIDI is a measure of how long an interruption to the gas supply lasted on average during a particular year.
Unaccounted for Gas, or UFG, is the difference between the total volume of gas entering the system at the Sales Gates less the total volume of gas exiting the network where it enters the meter at the Gas Measurement System installed on the consumers’ properties.
There are many factors that can effect UFG and whilst losses will occur as the gas is transported through the network, known as Technical Losses, there are numerous other non-network factors than can create adverse UFG quantities e.g. accuracy of the meter in the GMS or, the need for retailers to estimate monthly sales to consumers due to the cyclic nature of meter readings. The value of UFG as a measure of network performance should not be undervalued but considered alongside other measures such as the number of gas escapes as shown in the following table.

Responsible Manager: Approved by Directors: 6 July 2015 Page 33 of 69
General Manager
The number of gas escapes found by Survey methods increased in 2012/2013 from previous years. The increase was due to a change in the leakage survey procedures. Prior to 2013/2014 leak surveys were arranged by area, i.e. the network was divided up into similar sized areas and survey was completed on a 4-5 year cycle. In 2013/2014 leak survey procedures changed to include a specific survey of all low pressure metallic pipes across all of Wanganui. The risk based survey targets assets that are at a higher risk of leakage
Third party is the term used to refer to people and organisations, other than GasNet. In most instances third parties are contractors installing and maintaining other utilities’ assets, but it does include home and property owners.
Over the last two decades up until 2011 Wanganui had seen unprecedented activity within the road corridor as the Wanganui District Council undertook separation of its stormwater and wastewater systems. Requiring major excavations in most of the Wanganui streets the increase in activity inevitably resulted in an increase in enquiries about and damage to GasNet’s buried pipes. Ironically just as the project completed around 2011, the government’s fast-tracked Ultra-Fast Broadband project commenced with target completion planned within five years. The lull between the two activities can be seen in the level of enquires shown in the above graph, and the general profile of enquiries can also be seen in the ‘number of gas escapes’ graph above. The challenge for GasNet over the next few years will be to minimise the damage to its network which can only be achieved by working closely with the contractors and taking the appropriate corrective actions when adverse events occur.
5.2 Quality of Supply
Currently GasNet has the following project in planning:
Project or programme Description
Low pressure network pressure uprating
Network pressure up-rating involving raising the LP network pressure from 2 to 5 kPag to enhance the quality of supply at the ICP which allows the consumer additional choice of appliances as many new appliances require 2.5 kPag.
5.3 Other reliability, Safety and Environment
Currently GasNet has the following projects and programmes in planning:
Project or programme Description
District Regulator Station Isolation valve project
Installation of isolation valves on all DRS. Includes valves on outlet and inlet mains to provide complete isolation of gas to DRS in the event of an emergency incident.
District Regulator Station Monitoring system
Installation of monitoring devices at all DRS to record and transmit data to a central location at GasNet. Equipment monitors DRS operational parameters and transmits alarms real time to a database to activate emergency response. The program has been in place for 5 years and was completed in late 2014.
Monitoring and control systems
Installation of security monitoring equipment at the Wanganui Sales Gate to enhance the reliability of network supply by providing early detection of unauthorised persons. This project was completed in 2014 although further security enhancements are being considered for other strategic network assets such as selected DRS.

7.0 LIFECYCLE ASSET MANAGEMENT PLANNING (MAINTENANCE AND RENEWAL)
7.1 General
The Networks are operated to safely manage the risks identified in the hazard identification, risk assessment and control process and to meet functional requirements. The functional requirements include the provision of an integrated supply system capable of meeting consumer demands at all times as forecast by gas retailers and responding to emergency situations as and when they arise. All system operational activities are carried out in accordance with the GasNet’s Safety and Operating Plan.
7.2 Asset Replacement and Renewal
Asset Type Commentary
INTERMEDIATE PRESSURE SYSTEM
Main pipe
The existing 100mm and 150mm diameter mains pipes that cross an open watercourse adjacent to the Wanganui Sales Gate are planned for relocation in conjunction with the Wanganui District Council (WDC). The two pipes, which were installed in 1972 and 1985 respectively, are critical assets as they supply the entire Wanganui network. The two pipes are located above the watercourse and below the water line, and continually immersed in tidal salty/brackish water. One is encased in a carrier pipe the other is not. As they are continually below water it is difficult to access the pipes to inspect them to confirm that the pipe coatings and Cathodic Protection System are providing the necessary corrosion protection. In addition there is a risk of physical damage when the drain is periodically dug out which will increase with the lowering of the drain bed.
Service pipe Nothing planned
Stations
Some existing station equipment has become obsolete or in other cases replacement parts are becoming uneconomic to procure, requiring replacement with a modern equivalent. Installation of replacement equipment requires modifications to design. Some station enclosure roofs are showing signs of corrosion and will require replacement over 5-10 years.
Line valve No replacement of IP valves planned. Many valves are not accessible from the surface and require excavation. Valves identified as strategic to have chambers (risers and lids) installed to enable easy access.
Special crossings Nothing planned
MEDIUM PRESSURE SYSTEM
Main pipe Works planned to identify quantity and location, and to test material to determine life remaining.
Service pipe Nothing planned
Stations
Some regulator equipment installed is becoming obsolete requiring replacement with a modern equivalent. Installation of replacement equipment requires modifications to design. Station enclosures will require refurbishment over 5-10 years. Replacement of the access gates and installation of a safety barrier at the Medium-Low Pressure District Regulator Station at Victory Place, Wanganui is planned to be completed in the 2015/16 financial year.
Line valve Nothing planned
Special crossings Nothing planned
LOW PRESSURE SYSTEM
Main pipe
Metallic low pressure mains replaced on the basis of condition. Increased level of replacement focused on mains with historically high risk of leakage.
Service pipe
Metallic services are replaced by polyethylene when the main is replaced. Forecast increasing number of older metallic service replacement on the basis of risk identified. Service pipes located under buildings are high priority for relocation and are replaced and/or relocated as identified.
Line valve Nothing planned
Special crossings Mechanically jointed LP metallic rail and bridge crossings have elevated safety risk profile and are planned for replacement. The crossings are planned for replacement over the next 10 years.

7.3 Identified Material Lifecycle Asset Management Programmes
7.3.1 Network
Currently GasNet has the following network programmes in place:
Programme Description
Replacement of LP non PE Replacement of LP non PE mains and services. The metals used in the LP network include wrought and cast irons, spiral riveted, spiral welded, Mannesmann and galvanised steels. Mains constructed of each of these materials have their own characteristics. Steel mains are likely to be in good condition provided the coating is intact and joints are sealed and the cast iron mains are generally in good condition provided the joints are sealed. The replacement of the metallic LP mains is prioritised on past and existing leakage patterns and involves all metal types.
LP crossings Review of the condition of these assets and where deemed necessary refurbish accordingly
Replacement of service valves Various types of service valve have been installed on the network over time. Each type of service valve has characteristics that make it more or less suitable for the present duty. Some identified types of valves are replaced when other work is being conducted at the ICP. A program will be developed to identify the type of service valve installed at each ICP and a program for the replacement if required
7.3.2 Non-Network
Currently GasNet has the following non-network programmes in place:
Programme Description
Safety Management System Following legislative changes, GasNet has implemented a safety management system dealing with public safety and public property protection from gas related GDB activity. This is a strategic programme involving many aspects of operations and associated safe work practices.
Regulatory Following legislative changes, GasNet has implemented a number of Commerce Commission Determinations applicable to GDBs of which information disclosure is but one. This is a strategic programme involving many aspects of business practices, documentation and reporting.

8.0 RISK MANAGEMENT
8.1 Overview
GasNet’s risk management process aligns with ISO 31000 to manage risk across the organisation. The risk management process provides a systematic approach for controlling hazards to an acceptable level, or developing appropriate control strategies and measures to minimise the level of risk. The risk management process follows a hierarchy of control whose principle objective is to eliminate hazards. If this is not practical, risks are managed as low as reasonably practicable (ALARP).
8.2 Hazard Identification
All hazards associated with the network assets are systematically identified, described, and documented through hazard identification processes. This covers not only those hazards that have the potential to harm the public or damage public property but also those that affect GasNet personnel and contractors and the environment. For existing assets this process is conducted on or before a predefined review date and whenever changes occur. For new assets the process is initiated in the design phase prior to assets being constructed and going into service. The characteristics of each hazard, its environment, and the exposure of people and property to it, are recorded. The results of the formal hazard and risk management processes are recorded in GasNet’s Risk Register.
8.3 Risk Assessment
A qualitative risk assessment is carried out on each hazard in accordance with ISO 31000 to determine whether it presents a significant risk of causing harm to persons, property or the environment. Risks determined to be low or negligible or demonstrated to be ALARP are deemed to be acceptable risks. For those risks that lie above the low or negligible level the costs and benefits are compared to establish the achievable reduction in risk magnitude to meet ALARP requirements.
8.4 Hazard Control
Subsequent to the identification of significant hazards, all practicable steps are identified and taken to control those hazards in the following order:
1. Elimination;
2. Isolation; or
3. Minimisation.
The extent of the controls applied is decided by the:
Level of risk (high, medium or low) that the hazard represents;
Costs and benefits of applying the control measures; and
Current body of knowledge, for example good and accepted practices.
The controls applied to each hazard are designed to lower the likelihood of harm or property damage occurring so that the residual risk is as low as reasonably practicable. The effectiveness of the controls applied to each significant hazard is assessed on a regular basis through the implementation of a monitoring and verification process.
8.5 Coverage
The hazard identification, risk assessment and hazard control processes are carried out to address:
(a) Hazards or potential hazards identified during the design, construction, commissioning, operation, maintenance, failure mode, and decommissioning of assets;
(b) The security and control of access to the assets; and
(c) The implementation and management of contingency plans for emergency situations that may affect, or be affected by the assets.
8.6 Review
In determining when hazard and risk reviews are conducted to test the continuing effectiveness of control measures taken, assessments are updated for the following reasons:
Implementation of audit findings;
Proposed changes to the assets that may change the nature or scale of hazards, the operating parameters or asset design;
Changes to the environment in which the assets are operated;
Incidents and other experience from elsewhere in the system, or from other supply systems, or from anywhere else that might be relevant;
Following an emergency;
Performing non-routine activities;
Following changes in legislation; and

The passage of time.
8.7 Information Availability
The information from the identification and control of hazards is made available as appropriate to parties working adjacent to or, in the vicinity of the hazard, or responding to emergencies on the Network in accordance with GasNet’s Risk Management Policy supported by the suite of Safe Work Procedures (SWP’s).
8.8 Some Specific Observations
GasNet undertakes on-going monitoring across all networks for any options to increase network security. This could be achieved by implementing system looping and/or construction of additional sale gate connections to the high pressure transmission pipeline owned and operated by Vector Limited. Opportunities tend to be rare given the inherent reliability of networks in general and the very high capital costs involved in looping and sale gate construction.
As part of implementation of a complete Safety Management System regime for public safety and public property protection in proximity to GDB assets, GasNet recently achieved Safety Management System accreditation becoming the first GDB in New Zealand to gain this. Inherent to this success was satisfactory evidence of competencies, processes and documentation applicable to the Safety Management System requirements. While the Safety Management System in itself is one aspect of GasNet’s overall regulatory requirements, this accreditation provides a level of formal recognition of the practices more generally undertaken at GasNet.
9.0 ACTIONS COMPLETED
In accordance with clause 2.12.8(2)(g) GasNet is required to identify any actions it has completed in order to conform to the requirements in clause 2.6.1 which relates to the provisions of a fully compliant Asset Management Plan as compared to the Transitional Asset management Plan GasNet has elected to provide.
Other than the provision of this document as its first AMP, there are no other actions of significance worthy of mention since the majority of effort has gone into production of this document and the associated collation of information.
However it is expected that in conjunction with the improvement plan discussed below, the progressive enhancement and development of systems to support GasNet’s asset management system and its Asset Management Plan, subsequent revisions of this AMP will provide details of actions completed since publication of the previous AMP.
10.0 IMPROVEMENT PLAN
In accordance with clause 2.12.8(2)(f) GasNet is required to identify where it considers it does not yet conform to the requirements of clause 2.6.1 which relates to the provisions of a fully compliant Asset Management Plan as compared to the Transitional Asset management Plan GasNet has elected to provide.
It is GasNet’s view that other than its inability to provide the information required in Schedule 12b: Forecast Utilisation, that it complies with the requirements and is well placed to provide evidence of that compliance by publishing a fully compliant Asset management Plan by the end of the first regulatory period at the latest. In addition to the need to formalise its asset management strategies and practices referred to elsewhere within this AMP, there is a need to review its information systems to align with the information requirements under the IDD wherever possible and practicable to do so.
In respect to non-compliance with Schedule 12b: Forecast Utilisation, GasNet purchased the Synergi Gas network modelling analysis application in late 2014 with implementation of the application underway along with manipulation of the GIS data, a primary data source for the model. At the time of preparing this AMP it was anticipated that beta testing would commence in the third quarter of 2015. It was originally hoped that it will be operational by the end of the 2014 calendar year and that GasNet may be in a position to provide some network utilisation information by 30 June 2015, but it is now likely that it will not be operational until early 2016.

Appendix 3.2 – Schedule 14a: Mandatory Explanatory Notes on Forecast Information
Commentary on difference between nominal & constant price capital expenditure forecasts (Schedule 11a)
1. In the box below, comment on the difference between nominal and constant price capital expenditure for the disclosure year, as disclosed in Schedule 11a.
Box 1: Commentary on difference between nominal and constant price capital expenditure forecasts
The difference between nominal and constant price capital expenditure forecasts is due to forecast indexation being applied, based on the Change in CPI, 2 Index forecasts provided by the Commerce Commission in its Financial Model for the GPB DPP. As the Commissions data set only extended to December 2018 the remaining years were assumed to remain constant at 2%.

Schedule 12b: Forecast Utilisation
GasNet is unable to estimate physical capacity of systems in aggregate or that of an individual system due the complexity of the network modelling, lack of operational data and sites throughout each network and the absence of sophisticated modelling software to achieve robust reproducible results.
GasNet has reviewed how it could go about calculating current and thus future utilisation of each network as sought in the Report. GasNet has concluded that while some improved data capture instrumentation is now available on the Wanganui network, and with similar instrumentation to be added to other networks in coming financial years, there is both a lack of sufficient time series of data points and confirmation that all necessary sites are being sampled to enable any sensible estimates to be made at this time.
GasNet has purchased Synergi Gas network modelling software which when fully operational is expected to enable GasNet to provide the information necessary to populate this schedule.
