Driven by a framework agreement signed with Woodside Energy (Senegal) BV, ocean services provider DeepOcean will be supervising subsea inspection, maintenance, and repair (IMR) services for the Sangomar field offshore Senegal, West Africa

“We have extensive experience from similar IMR operations offshore West Africa, but this is our first project offshore Senegal and with Woodside. We look forward to being Woodside’s subsea IMR supplier here over the coming years and to demonstrate our competence and extensive pool of specialist subsea tools and underwater assets,” said Øyvind Mikaelsen, CEO of DeepOcean.

With a permanently moored floating production storage and offloading vessel (FPSO), the Sangomar deepwater oil field 100 kms south of Dakar has just begun production. The repurposed FPSO started sail from Singapore last December to travel 12,000 nautical miles.

Extensive offshore infrastructure

Driven by 24 subsea wells and associated subsea systems that comprises of wellheads and subsea trees, in-line tees, manifolds, flowlines and risers, flowline-end terminals, and umbilicals, the project demands long-drawn services from DeepOcean. Its scope of work will include project management, engineering, and execution of subsea services such as inspection, survey, intervention, and maintenance, as well as additional services such as underwater inspection of FPSO (UWILD) and standalone ROV operations. The Norway-based provider will be supported by a Senegalese service company called Teranga Oil and Gas Services SARL.

“Sangomar is a large and impressive field development, with extensive subsea infrastructure. Our aim is always to inspect and maintain it as effectively as possible, thereby keeping costs and operational disturbances to a minimum for Woodside,” said Mikaelsen. 

A project of strategic importance, the Sangomar oil field is supported by investments from the Africa Finance Corporation
