DOF wins TotalEnergies FSO replacement contract

Norwegian offshore vessel owner DOF has secured a contract from TotalEnergies covering subsea construction, mooring, the disconnection of an existing floating storage and offloading unit and the connection of a replacement. The work is in the Atlantic region and forms part of the FSO Unity replacement project.

The scope covers engineering, transportation and installation of mooring systems along with associated subsea construction. Four as-yet-unnamed vessels will be deployed, totalling around 330 vessel-days, with offshore execution planned for the fourth quarter of 2027 and the first quarter of 2028. Financial details were not disclosed, but DOF described the contract as large, which places it in the $50m-$100m range.

Project management and engineering will begin immediately from DOF's offices in Aberdeen, Scotland, and Bergen, Norway. Chief executive Mons S. Aase said the contract was a significant addition to the company's backlog and strengthened its long-standing relationship with TotalEnergies.

The FSO Unity can store about 2.2m barrels of crude and measures 300 m in length. It receives crude at a rate of 230,000 barrels a day from the Amenam-Kpono field and the Alfia, Ime, Edikan, Ofon and Odudu fields offshore Nigeria, handling dehydration, storage and transhipment of the oil.
