Italian contractor Saipem awarded Singapore-based Sembcorp Marine a US$484 million contract to convert two FPSOs for Total’s Kaombo project offshore Angola.
Sembcorp subsidiary Sembawang Shipyard will convert two very large crude carriers (VLCCs) sister ships into two turret-moored FPSOs for the project.
This work is a part of the original contract Total awarded Saipem in April 2014. Saipem will also be responsible for operation and maintenance services for the two FPSOs. That contract is worth $1 billion and is for a duration of seven years.
Semcorp’s contract includes refurbishment of the VLCCs, construction engineering, the fabrication of flare, helideck, upper turret and access structure, integration of the topsides modules and lower turret components, and pre-commissioning of the FPSOs.
The two converted FPSO units, owned by Total, will each have an oil treating capacity of 115,000bo/d, a water injection capacity of 200,000bo/d, a 100MMscf/d gas compression capacity and a storage capacity of 1.7MMbbl.
The first VLCC, Olympia, is expected to enter Sembawang shipyard in 3Q 2014 while the second VLCC, Antartica, will be in the shipyard by 1Q 2015. The total project duration will be 32 months, Sembcorp said.
Kaombo is located in block 32, at 1400-1900m water depth, about 150km off Angola. Operator Total seeks to develop six fields (Gengibre, Gindungo, Caril, Canela, Mostarda and Louro) in the central and southeast part of the block. The development will comprise 59 subsea wells, connected to the two floating production vessels. It will make use of "hybrid loop" technology for multiphase pumping and transport of fluids. The project is scheduled for completion by 1H 2018.
In April 2014, Technip and Heerema Marine Contractors were awarded a contract for an engineering, procurement, construction, installation (EPCI) and pre-commissioning for subsea umbilicals, riser and flowlines (SURF). Aker Solutions is providing the subsea production system for 20 subsea manifolds and 65 vertical subsea wellsets.
In June, Bluewater announced it would provide engineering for two complete deepwater turret mooring systems and the related procurement and construction of two turret and swivel systems.
Total’s partners in block 32 include Sonangol P&P (30%), Sonangol Sinopec International (20%), Esso Exploration and Production Angola (Overseas) Ltd.(15%) and Galp Energia (5%).
