4.0 Design Service for Wellhead Hook-up Replacements

2.17 This section details the requirements and the limitations of the Design Service for Flow line Header and Hook-up replacements and depending on the type of well, the Design Service for Flowline, Header and Wellhead Hook-Up replacements will comprise some or all of the following Design aspects:

Hook-up of any type of well at the well pad (e.g. Oil / Gas / Water, Free Flowing, Gas Lifted, ESP, Injection Wells, Disposal Wells, Positive cavity Pump (PCP), etc.) with various combinations of materials like carbon steel with Fusion Bonding Epoxy (FBE) coatings, HDPE lining, internal coating and rotolining) and associated utilities support (Electrical, Instrumentation).

Hook-up of any type of Flow line(s) and Header(s) from well pad to Facility / Manifold / MSV.

Flowlines and Headers of various combinations of materials like carbon steel PE lining and internal coating)

Buried and underground Flowlines and Headers road crossings.

All other associated works.

2.18 Contractor's Scope of Service will be defined by Company approved "Flow line and Wellhead Hook-Up" form and drawings, which detail, amongst others:

Well location.

The type of well.

The required size of replacement Flowline or Header size.

Any other specific requirements, if required.

2.19 The intention of the Design Service for replacement of Flow line, Header and Wellhead Hook-Up is to prepare a specification to allow a Contractor to route the flow line, prepare shop drawings, and construct the line. A gas lifted well with gas lift line and oil flow line is considered a single Flow line / Wellhead Hook-Up.

2.20 Contractor shall use Company standard package for well pad hook-up for each type of hook-ups, with minimum Design input (Refer Document C6.1, Technical Specifications and Drawings).

4.1 General

2.21 Contractor shall use Company's standards during the Flow line, Header and Wellhead Hook-Up replacements related Design Service (Refer Document C6.1, Technical Specifications and Drawings).

2.22 Majority of Company's standard drawings are 'typical' drawings and some Design Work is required by Contractor to tailor these drawings to the specific situation at Site. Such Design Work may include but is not limited to taking copies of standard drawings, renumbering drawings, renumbering instrument tags, and updating actual operating parameters. Any such Design work required is deemed to be part of the Design Service for replacement of Flow line, Header and Hook-Up.

2.23 Basis for the Design Service shall be a Company issued Scope of Service. Depending on the nature of the work a narrative, sketch(es), marked-up drawing(s) or inspection may be issued instead of the Scope of Work.

2.24 Contractor shall check whether the Scope of Service provides enough information to define the required Design Service. If not, Contractor shall ask Company to clarify the Scope of the Design Service Work.

2.25 Replacements will always be on a 'like for like' basis to the original or current piping specifications. Other minor projects will not entail modification to P&IDs. For

redesign or process modifications the requirement in section 4 shall be followed. Note that Company approved Design consultants with ISO9001 certified shall perform such activity.

2.26 In case a type of wellhead hook-up is not yet covered by Company's standard drawings, and no project specific drawing package is issued by Company, Contractor shall revert to Company. In such case Company will normally advise Contractor to base the Design Service on:

Company standard drawings for a similar hook-up, or

Company general or project specific drawings for a similar hook-up.

2.27 General or project specific drawings produced previously by Contractor for a similar hook-up.

9.0 Discipline Controls and Assurance Framework (DCAF)

2.49 Company operates a Discipline Controls and Assurance Framework (DCAF) system that identifies and lists business critical decisions/controls and deliverables requiring sign-off by authorised individuals (i.e. Technical Authorities).

2.50 Technical Authorities are individuals assessed to be competent to sign off decisions and deliverables within their applicable discipline and approved scope.

2.51 Contractor shall propose and submit for approval Technical Authorities (TA2 & TA3) to the Company Engineering Team Leader and relevant Company Corporate Functional Discipline Heads (CFDHs), i.e. the Technical Authority level 1, in accordance with GU272 and SP-2061 “Engineering and Operations Technical Authorities System”.

10.0 Asset Integrity – Process Safety MANAGEMENT (AI-PSM)

2.52 Asset Integrity – Process Safety Management (AI-PSM) describes the way in which Company manages its Assets to ensure that their physical and operational integrity is maintained and that the chance of a major incident occurring is as low as reasonably practicable.

2.53 AI-PSM is underpinned by effective design, operation, maintenance, management systems and leadership at all levels and all stages of the asset lifecycle. As such, effective Process Safety is directly linked to effective business performance where people and management systems are fundamental to successfully delivering sustained performance.

2.54 Company’s AI-PSM management system is therefore based on the following key elements:

Design integrity – design in a manner that ensures risks are As Low as reasonably Practicable (ALARP).

Technical Integrity – constructing and maintaining the hardware ‘barriers’ (safeguards).

Operating Integrity – operating the facilities within specified limits and Personnel and Contractors are competent and compliant.

People and Systems – establishing and maintaining Company core values, behaviours and management processes required for the effective management of AI-PSM.

2.55 Company has dedicated significant resources to AI-PSM embedment, which is led at Director-level. This AI-PSM champion holds overall accountability for AI-PSM improvement in the Company and is supported by the Asset teams and AI-PSM Working Group who ensure that annual business plans and KPIs for AI-PSM are implemented to address the four areas of AI-PSM. Implementing these plans ensure improvements are made in key areas such as the Permit to Work (PTW), Live Operating Envelopes, Alarm Management, Integrity management and Assurance.

2.56 Effective management of AI-PSM will reduce major accident risks, ensure stakeholder confidence in the business and provide assurance for the delivery of safety and production goals.

2.57 AI-PSM controls are embedded in Company’s DCAF system (see section 12 above). However, Company management requires assurance that AI-PSM controls are delivered and approved by the appropriate Technical Authorities for all projects that involve Process Safety hazards (e.g. hydrocarbon gas, crude oil, natural gas liquids, significant concentrations of Hydrogen Sulphide, etc).

2.58 Throughout the delivery of Services Contractor is required to comply fully and collaborate with the AI-PSM controls imposed by the Company.
