Singapore-based Keppel Shipyard has won three vessel conversion contracts worth S$103m ($81.57m) from PTSC Asia Pacific, Perenco Group and BC Petroleum.

Under the first contract, Keppel Shipyard will convert a tanker to a floating production storage and offloading (FPSO) unit for PTSC Asia Pacific, a joint venture company between PetroVietnam Technical Services (PTSC) and Yinson Holdings (Yinson).

The contract also includes refurbishment and life extension works, fabrication and installation of the flare tower, helideck, pipe racks and power generation module, as well as installation and integration of topside process modules and external turret, and upgrading the accommodation facilities.

Work on the FPSO is expected to start in the third quarter of 2012 and is scheduled for completion in the third quarter of 2013.

Upon delivery, the FPSO will be deployed in the Thang Long and Dong Do oil fields located in the Cuu Long Basin, offshore Vietnam. It will be able to produce 15,000-20,000 barrels of oil per day and will have a storage capacity of up to 650,000 barrels.

The second contract from UK-based Perenco includes the conversion of a tanker to a floating storage and offloading (FSO) unit.

Conversion of the tanker is expected to be completed by the first quarter of 2013 and the unit will be named FSO Mayumba. It will be stationed in the Lucina field, offshore Gabon.

Under the third contract from BC Petroleum, the company will modify and upgrade a tanker to an early production vessel (EPV) called Balai Mutiara and after the conversion the vessel will be deployed in the Balai Cluster oil fields, offshore Malaysia.
