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".

Coupled dynamic response of a three-column mini TLP

“…Several mini TLP designs have been discussed in the literature. These are: a downsized four column mini TLP for 1000 m water depth ; a family of concrete mini TLPs for generic applications (Logan 1996); a three column TLP for 800 m water depth, easily extendable to 1500 m under shorter development schedule with significant reduction in cost (Muren 1996); a mini TLP with vertical cylindrical hull connected to three radially tapered rectangular pontoons called SeaStar (Kibbee 1996 andKibbee et al 1999). …”
