Heerema Marine Contractors chose 2H Offshore to engineer hybrid risers for Total’s Kaombo Block 32 project offshore Luanda, Angola in 1400-1900m water depth.
2H Offshore's scope of work includes performing part of the detailed engineering of the 18 single top tensioner risers selected for the Kaombo development. 2H Offshore will also be 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 project is currently in the detailed engineering stage with also contracted to support Heerema through the procurement, fabrication and installation phases.
About the Kaombo project
Operator Total and its project partners will develop six of 12 discoveries, covering 800sq km, through 59 subsea wells, connected to two floating production vessels, each with a capacity of 100,000b/d.
Kaombo is Block 32’s first development and plans call for the production of several oil deposits scattered among six fields: Gengibre, Gindungo, Caril, Canela, Mostarda and Louro, located in the central and southeast part of the block.
It is currently in development based on the use of the state-of-the-art “hybrid loop” technology for multiphase pumping and transport of fluids.
Nearly US$8 billion worth of contracts for the Kaombo mega-project were announced in April 2014 including an estimated $3.5 million contract between Technip (55%) and Heerema (45%) for the EPCI and pre-commissioning of the SURF scope.
Other contracts went to Saipem, and Aker Solutions.
The project is scheduled for completion in the first half of 2018.
Total operates the Kaombo development with 30% interest. Its partners include Sonangol (20%), China Sonangol Petroleum (20%), Exxon (15%), Marathon Oil (10%) and Galp Energia (5%).
