摘要

The deep draft semisubmersible is a result of an ongoing development of new and cost effective solutions for marginal deepwater fields using existing technology in a new application. The deep draft semisubmersible consists of a well proven hull configuration used on several applications such as Snorre B in the North Sea and P-51, P-52 in Brazil, combined with a simple and cost effective deck solution similar to what is used on the Njord platform in the North Sea. The relatively low motions associated with this concept allow the use of steel catenary risers (SCRs) in typical GoM environments. A typical design is developed for a marginal field case with a topside payload of 3000 tons. This paper presents the concept and design work performed to verify the feasibility regarding motions, structural hull and topside design, SCR design, fabrication and installation.
