DOF Subsea has secured a contract to provide a full-time underwater services and multi-purpose supply vessel (MPSV) to Shell's Prelude floating liquefied natural gas (FLNG) facility in Western Australia.

The five-year inspection, maintenance and repair (IMR) contract has two optional two-year extension periods.

Prelude FLNG will produce, liquefy, store and transfer LNG at sea.

DOF Subsea CEO Mons Aase said: "This is a very important contract award for DOF Subsea, and the award further strengthens DOF Subsea's position in the global subsea IMR market.

“We look forward to working with Shell Australia on the world leading Prelude FLNG facility."

Under the contract, DOF Subsea will provide project management, engineering and integrated services for IMR programmes, as well as the dedicated vessel and options for other vessels.

"The award further strengthens DOF Subsea's position in the global subsea IMR market."

Shell took the final investment decision on the Prelude FLNG project on 20 May 2011 and started building the facility to produce and export LNG off the coast of Australia.

The project is 67.5% owned by Shell, while other partners are Inpex (17.5%), CPC (5%) and Kogas (10%).

Fabrication of components for the global project is taking place worldwide.

Hull and topsides for the FLNG are under construction at the Samsung Heavy Industries (SHI) shipyard.

Once operational, the FLNG will have the capacity to produce at least 5.3 million tonnes per annum (Mtpa) of liquids, 3.6Mtpa of LNG, 1.3Mtpa of condensate and 400,000tpa of LPG.
