Senegal: DeepOcean awarded a contract for subsea services on the Sangomar field

Ocean services provider DeepOcean has signed framework agreements with Woodside Energy's Senegalese subsidiary to provide subsea inspection, maintenance and repair (IMR) services for the Sangomar field, located offshore Senegal in West Africa.

The scope of work includes project management, engineering and execution of subsea services such as inspection, survey, intervention and maintenance. Additional services, such as subsea inspection of the FPSO (UWILD) and autonomous ROV operations, are also included.

DeepOcean hired its local partner, Teranga Oil and Gas Services SARL, to carry out all the work.

The framework agreements were awarded to Searov Offshore, a subsidiary of DeepOcean, which will work with DeepOcean's office in Sète, France, and Teranga Oil and Gas to plan and execute the services.

The Sangomar deepwater oil field, located 100 kilometres south of Dakar in Senegal, began production in June 2024.

Øyvind Mikaelsen, CEO of DeepOcean, said, "We have extensive experience of similar IMR operations offshore West Africa, but this is our first project offshore Senegal and with Woodside. We look forward to becoming Woodside's subsea IMR provider in the coming years and demonstrating our competence and extensive fleet of specialist subsea tools and assets."

The Sangomar field includes a floating production, storage and offloading (FPSO) vessel, named Léopold Sédar Senghor, as well as 24 subsea wells and associated subsea systems.

Subsea infrastructure includes subsea wellheads and trees, in-line tees, manifolds, flowlines and risers, flowline end terminals and subsea umbilicals.

"Sangomar is a large and impressive field development with extensive subsea infrastructure. Our aim is always to inspect and maintain it as efficiently as possible, minimising costs and operational disruption for Woodside," added Øyvind Mikaelsen.

DeepOcean currently has operational sites in Congo-Brazzaville, Equatorial Guinea, Gabon and Ghana in West Africa.
