A Singapore based energy services company on Wednesday announced the completion of a subsea infrastructure, umbilicals, risers and flowlines (SURF) project at the Natuna gas field in northern Indonesia, where its vessel Ullswater was deployed.

Hallin Marine has completed a USD 3m SURF project for an Indonesian company at the Natuna gas field in the Greater Sarawak Basin. The project focused on the deployment of Hallin’s DP2 Subsea Operations Vessel (SOV) Ullswater to lay new underwater umbilicals, the Singapore firm said in a press release. The project 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,” details 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,” he said.

Fully equipped for wellhead servicing, inspection and construction diving and remotely-operated vehicle support, the 78 metre long by 20.4 metre wide Ullswater incorporates a 15-man saturation diving system capable of operating at 200 metres 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, the Natuna gas field is located approximately 1,100 kilometres north of Jakarta. It is the largest gas field in southeast Asia, with estimated recoverable reserves of 46 trillion cubic feet.
