GSF Grand Banks spends about two days on its own in stormy seas
The crew of the GSF Grand Banks are being commended by the rig owner for their work in handling the semi-submersible, after the rig lost its tow and spent two unplanned days on its own in the North Atlantic last week.

The drill rig, with 99 crew aboard, was on its way to the southern United States last week, being towed by the Atlantic Hawk, when the tow was lost about 333 kilometres south of Cape Race and 315 kilometres east of Sable Island, Nova Scotia.
“After the tow line broke, the crew of the rig used the rig’s thrusters and its own power to navigate during this bad weather,” said Guy Cantwell, a spokesman for TransOcean. The company owns the GSF Grand Banks.
The tow was not immediately re-established because of the harsh weather and wave height, with waves reported running to seven metres.
However, the rig was put back under tow on 1:30 a.m. Friday morning, Cantwell said. He did not have the exact co-ordinates immediately available.
“There was no imminent danger to the crew at any time,” he noted.
The lost tow line received attention after first being reported Friday by Rob Almeida at gCaptain, a site specializing in news of marine vessels and transports.
As of Monday morning, staff at the Canada-Newfoundland and Labrador Offshore Petroleum Board said they were aware of the event. However, while a drilling rig is under tow, it is considered a vessel and the responsibility of Transport Canada and, if required, the Canadian Coast Guard.
The GSF Grand Banks is destined for a shipyard in Mississippi, where it will undergo a scheduled assessment and have some equipment replaced before it is towed back to offshore Eastern Canada.
The rig remains under contract for use in the local offshore, with the primary contractor being Husky Energy. The rig is contracted under a two-year agreement, running into September 2015.
