Hallin back at Natuna gas field

Hallin Marine, a Superior Energy Services company, announces its return to the Natuna gas field off Indonesia. The project for a major engineering procedure construction, installation and commissioning contractor will be executed using the Ullswater subsea operations vessel. The total project value is approximately USD 6M.

Discovered in 1970 by Agip (Italy), the Natuna gas field is located approximately 1,100km north of Jakarta. It is the largest gas field in Southeast Asia. Estimated recoverable reserves total around 46 trillion cubic feet. “This latest Indonesian contract is scheduled to commence in June and has an estimated duration of 30 days”, explains Hallin East Division managing director Rik Zwinkels. “It will centre on an offshore construction campaign to support the laying of 4,200m of flexible pipelines and the installation of rigid risers at the platform. The job scope includes provision for project management and engineering services, saturation diving services, pre-lay survey using Hallin’s C-ROV work-class remotely operated vehicle, and the pre-commissioning of the pipelines using the subsea operations vessel Ullswater.”

Fully equipped for wellhead servicing, inspection and construction diving as well as remotely operated vehicle support, the 78-metre long by 20.4-metre wide SOV Ullswater incorporates a 15-man saturation diving system capable of operating at 200 metres depth and a three-man moonpool-launched diving bell. An integral 22-metre diameter helideck enables fast transfer of crew and operating staff. Up to 120 personnel can be accommodated on board.
