Environment

Offshore oil and gas exploration and development carry a high level of inherent risk. High risk industries require high reliability operations to ensure consistent and robust application of good (and best) practices to reduce the probability of an incident or accident to as low as reasonably practicable. These good practices must be applied throughout: • the design, integration, commissioning, operation and maintenance of equipment and systems • the development and application of operation and maintenance procedures • the training and assurance of competency of the personnel carrying out the activities In the context of asset integrity, all components of this high reliability equation are equally important. • Equipment must be, and remain fit for purpose • Equipment must be operated within its design envelope • Equipment must be operated and maintained by competent and qualified individuals.
A breakdown in any area can, and with time will, compromise the integrity of equipment and systems with the end result being the realization of the consequence of hazards that would have otherwise been mitigated.
High Risk Industry
10
Harsh Environment
• Local environment referred to as “Hostile”
• Severity and frequency of storm conditions
• Harsh environment demands rigid adherence to a comprehensive
Asset Integrity Management program (taking into consideration
design, quality, operation, maintenance, competency, etc.)
High Sea States
• Regional mean wave heights range from 3 m in the western region
to 4.5m in the east across February*
• Maximum wave heights can reach up to 16+ m
11 *Data from Strategic Environmental Assessment study of Eastern Newfoundland
Harsh Environment
11
High Winds
• We have had Maximum wind speeds reported above:
• 148 km/h, gusting to 167 km/h, at a height of 50 m
• 157 km/h, gusting to 175 km/h, at a height of 139 m
Icebergs, Pack ice
• In the last 15 years, there have been several occasions where the offshore
production facilities undertook precautionary production shutdowns (in
preparation for possible disconnect) due to pack ice and icebergs
encroaching within safety zone
Fog
• The offshore NL region has some of the highest occurrence rates of fog in North America
• These conditions impact visibility and awareness and vary geographically and seasonally
• The Flemish Cap region sees poor or very poor conditions ( < 2 km ) for 40% of some months*
• The Flemish Cap region sees less than good visibility ( < 10 km) for 57% of the year*
• On average in the last five years, installations reported cancelations to all flights 79 days annually, due to weather conditions such as fog, wave heights, and wind conditions
*Data from Strategic Environmental Assessment study of Eastern Newfoundland
Harsh Environment
• The Fleming-Drover Harshness Index was
developed by Nalcor in their Metocean study to
compare overall degree of harshness across
offshore regions
• The values are generated from parameters that are
highly important to offshore operations,
specifically:
• Sea Ice (Pack Ice) Concentration
• Sea State
• Iceberg density
13
*Data and information from “Nalcor Metocean Climate Study Offshore Newfoundland and Labrador - Study Full Report Volume 2”
Remote Environment
14
• Production platforms and MODUs are operating more than 350+ km from shore
• In comparison to other jurisdictions the infrastructure in this region is relatively small - currently we have 4
production facilities and 2 MODUs operating in the offshore NL region; with some additional seismic and
construction vessels during the summer months
• Typically includes standby vessels for each facility unless operating in the same field
• Travel can take 90 to 180 minutes by helicopter or up to 18-24 hrs by vessel under normal conditions

History Context
23
IRF - 2007 Asset Integrity
• December 2007 conference in Miami
• theme of the conference was asset integrity
• delegates requested IRF to more clearly define what was meant by the term, what should be
included and what IRF expectations were with respect to the key processes which should be in
place to ensure asset integrity.
In response to this request the following definition and key processes set out the views of the
regulators who form the IRF (of which the C-NLOPB is one of ten)
Definition
An asset (which includes structure, process plant and connected wells and pipelines) has integrity
when it meets design performance standards for effective control of risks and when the
management systems effectively support those standards.
24
IRF - 2007
Process :
Effective integrity management means knowing:
• all about the design and safe operation of all plant, equipment and systems,
• what can go wrong.
• effective measures are in place to prevent and control undesired outcomes.
• personnel are trained and competent.
• monitoring, inspection and auditing arrangements will verify that the desired outcome is achieved.
25
IRF - 2007
Process (cont’d):
The following represent IRF’s reasonable expectations for what needs to be in place for
companies to demonstrate effective management of the integrity of an asset.
• effective leadership from the top demonstrating understanding of integrity issues and
commitment to safe operation.
• clear and effective performance indicators.
• appropriate management metrics at all levels of management.
• effective management of integrity data.
• meaningful and effective performance standards.
• appropriate design standards
• comprehensive operations and maintenance management systems.
• effective risk assessment tools and procedures
26
IRF - 2007
Process (cont’d):
• effective audit of integrity management performance.
• effective cross business and cross industry learning.
• continuity of records during the lifetime of the asset.
• trained and competent workforce.
• clear management of change procedures.
• knowledge and understanding of risk control barriers at all levels
27
In 2007/2008 C-NLOPB undertook a project to establish a common understanding of the scope of
Asset Integrity
Project involved review of:
• other regulators expectations
• Industry associations in other jurisdictions
• Certifying Authorities
• Local industry programs
Outcome was a view that the Step Change in Safety KP3 program provided the most consolidated
summary of expectations in respect to Asset Integrity and Asset Integrity Management
28
C-NLOPB 2007/2008
Asset Integrity Life Cycle Management
Asset Integrity – The ability of an asset to perform its required function effectively and efficiently
while still protecting health, safety and the environment.*
Asset integrity management – the means of ensuring that the people, systems, processes and
resources that deliver integrity are in place, in use and will perform when required over the life cycle
of the asset. *
Asset Integrity is very broad in scope and applies to all equipment on facilities including:
• Pressure equipment (vessels and piping)
• Structures, Hulls
• Subsea equipment
• Wells and Trees
• Electrical systems
• Controls and Instrumentations
• Pipelines/Offloading Systems
• Machinery
• Telecommunication Equipment
• Safety Equipment
• Fire Systems
*Health and Safety Executive Key Programme 3 – Asset Integrity
29
KP3 Program
The Step Change program identifies six key elements or tools that need to be appropriately
addressed at each of the six stages in a facilities lifecycle. The six key elements are:
• Identification, assurance and verification of Safety* Critical Elements (SCE)
• Measures for assessment, control and monitoring of risk
• Competence of personnel, including 3rd party contractors
• Planning associated with integrity management
• Management of maintenance, inspection and testing
• Quality assurance and auditing
(* Safety refers to Safety of Life and the Environment)
30
KP3 Program
The Step Change program identifies six stages in a facilities lifecycle:
• Design
• Construction and Hookup
• Commissioning
• Operations
• Modifications
• Decommissioning

Asset Integrity - Decommissioning Stage
• Planning for this at the early stages
• Plug and Abandonment programs that isolate flow to surface and cross flow within a well
• Clearly defined End of Life of the facility
• A decommissioning program that returns environmental conditions to what they were prior to
the commencement of the project
45
Common Asset Integrity Challenges
• Corrosion under insulation (CUI) – inspection programs/technologies
• Fabric Maintenance
• Corrosion issues with produced water caisson, open drain systems (drain boxes and piping)
• Corrosion of hydrocarbon piping
• Use and extent of composite repairs (Temporary Repairs)
• Condition monitoring technologies for machinery/electrical
• Lack of comprehensive maintenance on low running hour equipment
• Frequent false alarms from fire/gas detectors due to fog and heavy precipitation conditions
• Temporary Safe Refuge Integrity Impairments
• Pipe Support deterioration
• Mooring Chain Integrity (general wear and bending stress, repairs require offstation)
• Well Integrity impairments – DHSV and Master and Wing valves failing to meet leak rates as well as
tubing leaks
46
Common Asset Integrity Challenges
• Deficiencies in general visual inspection (GVI) not clearly identifying the scope of what was
inspected and what was not (eg pipe behind other pipe not easily visible yet line indicated as fully
inspected)
• Crane integrity issues – slewing pinion gear, crack indications on lattice etc
• Impairments to lifeboats
• Impairments to helideck fire monitors due to extended sub zero temperature
• Management of deferred maintenance – an expanding backlog both in number of routines and in
person hours to execute
• Internal corrosion (pitting) in crude export, produced water and gas compression systems
(microbial corrosion)
• Hydraulic hose issues (cold weather and corrosion of end fittings)
• Pipe erosion (high velocity of fluid and bends in system piping caused pipe erosion)
• Valve issues on ballast control system
• Uncontrolled void space flooding due to corrosion
47
Key Take Away Points • This is a high risk industry that requires high reliability operations
• This is a harsh/hostile environment – Mother Nature is our harshest critic
• Our regulatory regime requires good/best practice taken in the context of good/best practice in similar operating environments
• We expect a conservative thorough approach to asset integrity management – this expectation is shared by our regulatory counterparts in the IRF
• Asset integrity must be considered and accounted for through the entire life cycle of an installation
• Asset Integrity must ensure that equipment and systems are tested, inspected, maintained and operated by qualified personnel to ensure safety and environmental protection under the maximum load and operating conditions that may be foreseeable during any operation and continues to perform in accordance with the original design standards
• This is not the first time any of us have turned our attention to Asset Integrity Management - It will not be the last time
• While good progress continues to be made in this area, there is still lots of work to do and improvements to be made
