INTEGRITY MANAGEMENT SYSTEM FOR THE ULTRA DEEPWATER MEDGAZ PIPELINE 23rd World Gas Conference, Amsterdam 2006
Jay Chaudhuri, MEDGAZ S.A., Spain Don Mackinnon, JP Kenny Ltd., UK Gopi Rengasamy, Infosys Technologies Ltd., UK The MEDGAZ Project
Project Highlights • Designed to deliver 8 BCM/y gas during Phase 1; potential for capacity upgrade to 16 BCM/y by installing a parallel pipeline. • The Medgaz system will consist of an onshore compressor station at Beni Saf, Algeria (BSCS) • A deepwater 24 inch diameter pipeline across the Alboran sea – Maximum depth: 2155 m – deepest depth for an European pipeline – Approximate offshore length: 210 kms • A gas reception terminal near Almería, Spain (OPRT) • Has received backing/funding from EU-TEN programme • Spanish and Algerian institutional support for First Gas in early-2009

3 Medgaz Project : Economic Rationale
• Spanish gas consumption has grown from 21.4 BCM in year 2002 to 28.3 BCM in year 2004 – Anticipated demand for year 2011 exceed 44 BCM
• Gas demand at 18% compound rate. – Contributing Factors • Manufacturing growth • Switching to ‘Kyoto Protocol’ friendly fuels
• Economic growth rationale for investments in infrastructure capacity of energy market
• Gas demand from CCGTs increased by 66% in 2005, compared to 2004 – Contributing factor: Start-up of a number of gas fuelled power stations (Source: Sedigas)
• Spain dependency on gas imports: 99.6% – LNG: 65% – Gas via pipeline: 35% – LNG price penalty factors: – liquefaction – sea transportation – re-gasification

• Pipeline integrity ‘core business’ objective for MEDGAZ
• Framework to resolve the issues of Pipeline Integrity Management resulting from conventional design-construction-operation approach
Long-term operational Phase Design phase Construction phase Phase
• Routing alternatives • Disjointed survey information and • Maintenance of accurate data CAD information from design and construction • Geophysical and geohazard phases and the project characterization of seabed and • Lack of simulation and accuracy ‘Knowledge Database’ underlying strata • Requirement of manual • Effective integration of In-Line- Contributing • In-service loading correlation of data at all stages Inspection database with the Factors construction ‘As-Built’ database • Construction/installation • Lack of centralized database assessments • Sub-optimal collaboration between survey, engineering, construction and handover to Operations
7 Managing Design Integrity
Design Issues • Minimisation of environmental impact • Protection of marine flora/fauna on the offshore and onshore sections on the Algerian and Spanish sides • Avoidance of natural obstacles that exist along the route • Low geological and geotechnical risks • Minimization of “free-span” risks
8 Managing Design Integrity: Leveraging Technology
ROV-TRITON XL-14
9 Managing Design Integrity: Geohazard evaluations
• Objective: To verify the integrity of the pipeline, thereby ensuring pipeline survival during extreme events. Assessments conducted • Geophysical interpretation • Probabilistic Seismic Hazard Assessment (PSHA) • Slope stability assessment • Probabilistic Fault displacement hazard analysis • Numerical runout modeling
Extreme failure events covered • Fault slip - reverse, normal and strike slip, and fault movement
• Slope failure - failure of the steeper slopes resulting in loss of support to the pipeline
• Mass sediment movements (turbidity flow and mud slide events) - impact of a fast- moving dense flow on the pipeline Canyon area on the Habibas Escarpment
10 Managing Design Integrity: Design code governance
• Medgaz pipeline design complies with the internationally known design code DNV OS - F101. • Extensive material and full-scale testing have been performed for design validation.
