OML 130 – EGINA FIELD DEVELOPMENT
TECHNICAL ASSISTANCE – SERVICE DESCRIPTION

Service Ref:  Team: Umbilical/Flowline/Riser (UFR)
Service Location: Lagos, Nigeria  Status: Resident / Local
From: Q3 2010 To: Q4 2014
Service Title: UFR Hydrodynamics engineer
Reporting to: UFR Engineering Manager

Context:
EGINA is a Deep Water Oil Development situated offshore Nigeria, on the OML130 block operated by Total Upstream Nigeria Limited. Egina development shall comprise a newly built spread moored FPSO connected to subsea wells via risers, flowlines and umbilical network with oil export via offloading buoy and gas export via a subsea tie-in to the existing Akpo-Amenam gasline.

Purpose of Service :
Supervision of engineering studies for risers / dynamic umbilicals / export buoy / oil offloading lines hydrodynamic analyses during project execution / detailed engineering.
Addressing technical clarifications and qualifications during tender phase.

Scope of Service :
• Acting as Specialist within UFR team and providing answers for all matters related to hydrodynamic analyses
• Managing the UFR contractor with respect to all riser design activities by reviewing and monitoring all relevant engineering documents throughout all project phases. Review hydrodynamic analyses (global, interference, fatigue analyses, etc) of the risers / dynamic umbilicals / export buoy / oil offloading lines covering transportation, installation and operation phases.
• Assisting in overseeing the design and fabrication related aspects for risers and associated appurtenances (top / bottom assemblies, buoyancy tanks, flexjoints, bulkheads, flexible jumpers), umbilical ancillaries (subsea arch, buoyancies), export buoy (mooring equipment), oil offloading lines appurtenances (end connections, buoyancies)
• Assisting in risers / dynamic umbilicals / export buoy / oil offloading lines installation and hook-up
• Assisting in interface management with FPSO & SPS contractors
• Assisting in analysis of UFR Contractor technical queries and preparation of comments and proposed answers to these queries
• Ensuring that engineering is performed in line with TOTAL general specifications and issue proper derogations, if required.
• Ensuring that HSE issues are taken into consideration during design.
• Getting assistance from TOTAL Specialists, or third parties, if required, for specific topics
• Getting feedback from other deepwater projects on risers systems
• Participating in various technical reviews (Hazids, Hazops, Project Technical Reviews,…)
