Hallin Supports Subsea 7 in Offshore Installation Work in Bay of Bengal

Hallin Marine, a Superior Energy Services company, reported Wednesday the start of a new subsea field development project for Oil and Natural Gas Corporation Ltd. (ONGC) in the Bay of Bengal offshore India working in support of Subsea 7. The project began in March and is expected to take three months. It is located in the G1 deepwater region of the highly productive G1-GS15 offshore production field.

India has, after China, the second-largest proven oil reserves in the Asia-Pacific region. Most of India’s crude oil reserves are located around the western coast and in the northeastern parts of the country. Considerable reserves are located in the offshore Bay of Bengal and these are now being developed.

“Return business is always a great vote of confidence for any service-provider, particularly in the oil and gas sector where the ability to work safely and efficiently in unpredictable operating conditions is essential,” says Phil Chamberlain, Hallin‘s director – Service Delivery. “Having completed Campaign 2 in 2013 successfully, on time and within budget, we are naturally very pleased to have been selected by Subsea 7 to support Campaign 3.”

Hallin will be providing the subsea operations vessel Ullswater with survey, air diving, and marine crews with Subsea 7 providing flexible and umbilical laying equipment and construction crew.

Fully equipped for wellhead servicing, inspection and construction diving as well as for installation support, the 256-foot (78-meter) long by 67-foot (20.4-meter) wide SOV Ullswater incorporates a 15-man saturation diving system capable of operating at 656 feet (200 meters) depth plus a three-man moonpool-launched diving bell. An integral 72-foot (22-meter) diameter helideck enables fast transfer of crew and operating staff. Up to 120 personnel can be accommodated on board.

“It is a pleasure to be working with Hallin Marine again,” says Jean Legrux, vice president Projects & Operations, Asia Pacific & Middle East at Subsea 7. “This is repeat business for Subsea 7 and Hallin which reflects the trust afforded by Subsea 7 as a result of our successful operation and cooperation on ONGC’s behalf during 2013. We look forward to a safe and successful completion of Campaign 3.”
