Early deployments of offshore wind power turbines used these structures. As of 2010, 14 of the world's offshore wind farms had some of their turbines supported by gravity-based structures. The deepest registered offshore wind farm with gravity-based structures is the Blyth Offshore Wind Farm, UK, with a depth of approx. 40 m. [3]
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 ...
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 ...
The field was discovered in 1979 with the Hibernia P-15 well, and is located on the Grand Banks of Newfoundland in the northwest sector of the Jeanne d'Arc Basin, the Cretaceous primary reservoir being the Berriasian and Valanginian age river delta Hibernia sandstones at a depth of 3720 m, structurally trapped in a faulted anticline.
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 price of a product or service is defined as cost plus profit, whereas cost can be broken down further into direct cost and indirect cost. [1] As a business has virtually no influence on indirect cost, a cost reduction oriented cost breakdown analysis focuses rather on factors contributing to direct cost.
The GBS is the culmination of three concepts: the hierarchical relationship of product development, the work breakdown structure and requirements traceability.. The concept of a hierarchical relationship among objectives in product development was identified by Joseph M. Juran in Juran's Quality Control Handbook [2] where he states in section 2.2, subsection Hierarchy of Product Features ...
The Constructive Systems Engineering Cost Model (COSYSMO) was created by Ricardo Valerdi while at the University of Southern California Center for Software Engineering. It gives an estimate of the number of person-months it will take to staff systems engineering resources on hardware and software projects.
