Energy services company Hallin Marine said it has completed a SURF (subsea infrastructure, umbilicals, risers and flowlines) project at the Natuna gas field in the Greater Sarawak Basin.
Valued at approximately US$3 million, the project centred on the deployment of Hallin?s DP2 SOV Ullswater to lay new underwater umbilicals, the company said in a statement Thursday. The schedule also included replacement and abandonment of existing system components as well as installation of new infrastructure.
?Completed in partnership with a major Indonesian contractor, the Natuna gas field project involves engineering, procurement, installation and commissioning,? said Rik Zwinkels, Managing Director of Hallin?s Singapore East Division. ?Ullswater?s advanced technical facilities, including saturation diving equipment and in-house built CROVs, were put to full use. The scope of this SURF contract also includes project management and engineering.?
The Ullswater is now enroute to her next offshore project, for another Indonesian oil company, Hallin Marin said.
Fully equipped for wellhead servicing, inspection and construction diving and remotely-operated vehicle support, the 78 meter long by 20.4 meter wide Ullswater incorporates a 15-man saturation diving system capable of operating at 200 meter depth plus a three-man moonpool-launched diving bell. The DP2 vessel has a 22 metre diameter helideck for fast transfer of crew and operating staff. Up to 120 personnel can be accommodated onboard.
Discovered in 1970 by Agip ( Italy ), the Natuna gas field is located approximately 1,100 kilometers north of Jakarta. It is the largest gas field in southeast Asia. Estimated recoverable reserves total around 46 trillion cubic feet.
