DNV has won a contract to class the Petronas LNG FPSO (FLNG) currently being built by South Korea’s Daewoo Shipbuilding & Marine Engineering (DSME).
The classification covers the floating structure, mooring arrangement and natural gas liquefaction technology.
The challenges of the project include cryogenic storage tanks tolerant to sloshing, topsides that include gas pre-treatment and liquefaction processing equipment and ship-to-ship offloading equipment suitable for LNG transfer at sea.
Daewoo’s shipyard in Okpo, South Korea, will be responsible for the engineering of the hull and the construction of the FLNG unit.
Scheduled to be operational in 2015, the vessel will be used to develop the Kanowit natural gas reserve off Bintulu, Sarawak, Malaysia.
The FLNG vessel will have a length of 300m, width of 60m and maximum carrying capacity of 1.2 million tonnes per year.
Once operational, the vessel is expected to increase Malaysia’s total LNG production capacity to 26.9 million tonnes a year from the current 25.7 million tonnes.
The FLNG vessel will help in transporting gas back to land-based liquefaction plants and includes liquefaction technology designed for use on a floating facility.
DNV vice president of floating gas project business development Conn Fagan said that the ability to process and offload LNG offshore will increase the viability of significant gas reserves in Malaysia’s remote and stranded fields.
"DNV is at the forefront of FLNG technology and we are building competence around the world to support Petronas in this project and other clients who are entering the field," Fagan said.
In June 2012, France’s Technip and DSME won a $771m contract from Petronas to provide engineering services for the FLNG unit.
Under the deal, the Technip-Daewoo Consortium (TDC) was responsible for providing engineering, procurement, construction, installation and commissioning (EPCIC) of the FLNG unit.
The contract followed the completion of a deal won by TDC in December 2010 for the front-end engineering design phase of the $2bn project.
