| Services | FEL 3 – FEED |
| Location | Algeria |
Objective
To complete the Front-End Engineering Design (FEED) for the Hassi Bir Rekaiz (HBR) Phase 2 development, in the Berkine Basin, Eastern Algeria, optimising the project for full-field production, minimising risk, and supporting the transition to the Engineering, Procurement, Construction and Commissioning (EPCC) phase.
Project Scope
- Developed FEED for Phase 2a, targeting a capacity of 31,500 stock tank
barrels of oil per day (STBOPD) with infrastructure to expand to 63,000
STBOPD in Phase 2b. - Entire infrastructure development as well as well sites, gathering and
processing facilities, and associated pipelines including industrial base,
accommodation, military camp, air strip and roads. - Integrated Phase 1 infrastructure into the new Central Processing Facility
(CPF) and designed brownfield modifications at existing facilities for oil
and gas exports. - Prepared EPCC tender documents and executed workshops, including
HAZID, HAZOP, SIL, 3D Model Review, Constructability, Human Factors
Engineering (HFE) and Value Engineering reviews. - Delivered a Class 3 Cost Estimate with complete with Cost Risk Assessment,
Level 2 schedule and entire EPCC ITT packages.
Key Execution Metrics and Outcomes
Key Execution Metrics
- Total Duration: 40 weeks
- Total Number of Deliverables: 3,039
- Full Time Equivalents (at peak): 90 (total of 135)
- Weekly Progress Achieved (at peak): 6.6%
- Client Management: 19 co-located in io’s main execution offices, London, fully hosted by io under contract (flights, accommodation, logistics and sustenance in-country)
Outcomes
- Value Engineering: Cost saving opportunities, such as pipeline optimisation (right sizing through detailed flow assurance, optimal corrosion allowance), optimised inlet processing facilities, wellsite power supply.
- Design Optimisation: The CPF design includes provisions for future Phase 2b expansion and improved water injection systems for enhanced oil recovery.
- Risk Reduction: Comprehensive HSE reviews identified and mitigated key risks, ensuring As Low As Reasonably Practicable (ALARP) outcomes.
Outcomes
- Technical Certainty: Detailed FEED across multiple disciplines with outcomes feeding the cost and schedule estimate and basis for EPCC ITT.
- Brownfield Details: Site survey to existing assets to ensure certainty of brownfield tie-in design and existing processing facilities capacities.
- Design and Safety Reviews: HAZID, HAZOP, SIL, 3D Model (x 3), constructability, HFE, risks, cost estimate.
- Operational Readiness: Philosophies, guidelines and requirements for commissioning and start-up for successful and seamless handover.
- Project Viability: Collaborative execution strategy enabled the project to remain within the revised schedule and achieve deliverable quality benchmarks.
- Stakeholder Alignment: Local authorities, partners and expected suppliers and key stakeholders required for success during execution.
io Value Add
io provided critical support in aligning technical, commercial and operational aspects, including:
- Comprehensive EPCC ITT: both technical and commercial aspects to allow GHBR a smooth tendering process with minimal clarifications and high degree of certainty.
- HSE Leadership: Facilitated HAZOP, HFE and ALARP workshops to ensure robust safety and risk mitigation. Including local authorities participation and requirements incorporation.
- Value Creation: Identified and prioritised value engineering opportunities, enhancing project efficiency and cost-effectiveness.
- Certainty: brownfield tie-ins and mitigations to risks on reliance with third parties.
- Stakeholder Collaboration: Engaged effectively with GHBR and stakeholders to ensure alignment and mitigate project risks.
By delivering a comprehensive and collaborative FEED package, io established a strong foundation for the successful execution of the HBR Phase 2 development. Establishing its Trusted Advisor status for Sonatrach and it’s partners.
