Industry-leading deepwater electro-hydraulic subsea safety system for GE in W. Africa

In Brief
Expro’s subsea expertise delivers industry-leading deepwater electro-hydraulic subsea safety system in West Africa
Product Line
Sub-Saharan Africa
  • In late 2012, General Electric (GE) challenged Expro’s subsea product line with delivering a complex deepwater (up to 1,700 meters) electro-hydraulic subsea safety system to be used in their West African operations, Block 15/06 – part of a contract with Eni 
Expro Excellence
  • Production of a system satisfying design requirements and delivery in time for subsea operations commencing in 2014, delivered by a multinational team split over two locations – Aberdeen and Luanda
  • Building a highly skilled operational team with an in depth knowledge of electro- hydraulic systems
  • Reacting to an exceptional scenario when a complete landing string was lost overboard during severe Atlantic storms - Expro replaced the lost system in record time preventing any delay in the well completion program
  • Final equipment testing coincided with the final commissioning of our new facility in Luanda, which required detailed planning to
  • ensure the delivery of equipment and
  • facilities were not compromised
  • In June 2014 the subsea safety system was
  • delivered on schedule and successfully completed a comprehensive set of acceptance tests before going operational
  • Operations were conducted in an efficient manner optimising rig up time and efficiency 
Value to client
  • Delivery of a complex, deepwater, electro- hydraulic subsea safety system with water depths of up to 1,700 meters, overcoming unique challenges
  • Expro delivered the equipment on time, equipment running time exceeded targeted efficiency, and avoidance of non-productive time (NPT) during the execution of the work
  • ENI has now started production of first oil from Block 15, with the field currently producing 45,000 barrels of oil per day, with an expected daily production of up to 100,000 forecast
  • Block 15 discoveries were developed in an industry-leading timescale of only 44 months from the Declaration of Commercial Discovery
