DeepOcean has been contracted by Tullow Oil to perform subsea riser intervention work at the Jubilee Field offshore Ghana, one of West Africa's most significant producing assets. The scope covers engineering, disconnection, re-termination, and reconnection services for a gas-lift riser that links the FPSO Kwame Nkrumah to the Jubilee Field subsea production system.
The contract is a signed service agreement, placing it firmly in execution territory rather than the planning or tendering stages. Gas-lift riser integrity work of this nature is technically demanding: the intervention requires precise subsea engineering to safely disconnect a live production-linked riser, carry out re-termination, and restore the connection to operational standard without compromising field uptime. The FPSO Kwame Nkrumah serves as the central processing hub for Jubilee, meaning any riser work directly affects production continuity for Tullow and its co-venturers.
Jubilee remains a cornerstone of Ghana's upstream oil sector and continues to attract specialist intervention and integrity work as the field matures. Gas-lift systems are a standard method of artificial lift used to maintain reservoir pressure and flow rates in maturing fields, and riser re-termination work of this kind signals active asset management aimed at sustaining production levels. The award to DeepOcean, a Norwegian-headquartered subsea services company, underscores the continued role of Scandinavian subsea specialists in West African deepwater operations.
For Norwegian oil and gas service companies tracking West Africa, the Jubilee Field remains an active procurement environment. DeepOcean's engagement here reflects a broader pattern of Norwegian subsea capability being deployed to support ageing but still-productive deepwater assets in the Gulf of Guinea. As fields like Jubilee enter later production phases, demand for integrity management, riser intervention, inspection, and well services work typically increases, creating a sustained pipeline of specialist contracts beyond the initial development phase.
