A Condeep type GBS under construction in Norway A gravity-based structure ( GBS ) is a support structure held in place by gravity , most notably offshore oil platforms . These structures are often constructed in fjords due to their protected area and sufficient depth.
This GBS is designed to resist iceberg forces and supports a topsides weighing 39,000 tonnes at towout, increasing to 58,000 tonnes in operation. There were significant challenges faced by the engineering firms Doris Development Canada, Morrison Hershfield and Mobil Technology in developing a structural solution with adequate strength which was ...
Norwegian Contractors AS was a concrete gravity base (GBS) structure supplier from 1974 to 1994. Aker Marine Contractors AS (AMC) was established in 1995 and is a continuance of the marine activities in Norwegian Contractors AS.
The Troll A platform has an overall height of 472 metres (1,549 ft), weighs 683,600 tons (1.2 million tons with ballast) [4] and has the distinction of being the tallest structure ever moved by mankind. The platform stands on four legs extending down to the sea floor 303 meters (994 feet) below the surface of the sea, and the leg containing the ...
Since then at least 47 major concrete offshore structures have been built.
