Boskalis has completed the return and reinstallation of an FPSO off West Africa, where the floating production unit had operated for decades and is expected to continue working for years to come.

The project began around a year ago when Boskalis disconnected the FPSO from the seabed infrastructure using BOKA Falcon and four assisting anchor handlers, including Manta, BOKA Expedition and BOKA Forward.

After the disconnection phase, the 403 m-long FPSO was towed to Dubai and entered dry dock for life-extension works. Once the work was completed, the unit was transported back to the African coast earlier this year by BOKA Alpine and BOKA Forward.

The final offshore phase has now been completed. Manta, BOKA Forward, BOKA Alpine and Princess held the FPSO in position, while BOKA Fulmar carried out the final mooring line replacement and hook-up installation works.

The operation closed a multi-stage marine services project involving disconnection, towage, dry-dock support, return transport and final installation. Boskalis said the work demonstrated its ability to deliver an integrated offshore service with several specialized vessels working across the project timeline.
