2H Offshore Secures Riser Engineering Offshore Angola

2H Offshore, an Acteon company, has been appointed by Heerema Marine Contractors (HMC) to engineer hybrid risers for Total’s Kaombo Block 32 project. HMC, together with consortium partner Technip, were awarded the contract for the EPCI and pre-commissioning of the SURF scope for the Kaombo development by Total.

2H Offshore has been pioneering riser analysis, design and engineering for more than 20 years and with this capability and experience, 2H will perform part of the detailed engineering of the 18 Single Top Tensioner Risers (STTRs) selected for the Kaombo development. 2H will work closely with HMC as a part of an integrated design team, with 2H responsible for the engineering of the Buoyancy Tank, Upper Riser Assembly and Lower Riser Assembly packages together with Global Analysis and Systems Engineering of the risers.

The Kaombo development, located offshore Angola in water depths extending from 1425m to 1925m, will include the Gindungo, Gengibre, Canela, Louro, Mostarda west and Caril fields tied back to two turret-moored FPSOs. The selected concept consists of a number of production loops with one insulated production riser and one non-insulated service riser per field. Water injection risers will also be required.

The project is currently in the detailed engineering stage with 2H also contracted to support HMC through the procurement, fabrication and installation phases.

Alex Rimmer, director of 2H’s Woking office, said “2H is proud and excited to be engineering the risers for the largest subsea field development project in the world. This award and other recent awards confirm 2H as the leading contractor for the engineering, design and analysis of a range of production riser technologies including hybrid, steel catenary, top tensioned and flexible riser systems. With a history of working together, we look forward to engaging with HMC on this and future projects.”
