In the US Gulf of Mexico, Tension Leg Platforms (TLP) are drilling and producing in 800 meters water depth and developments in even deeper water are underway. Current TLP technology can be extended to approximately 1,500 meters, but in order to make developments at such water depths (and deeper) economical, new and imovative solutions are required to reduce costs and shorten development schedules. The 3 cohunn TLP design described in this paper satistks such requirements. The concept features a simplified and cost effective tendon system and a modularized deck design utilizing a "splash zone truss".
