A new milestone has been passed in offshore development with the completion of the Snorre (Phase I) field installations this summer. The installation are located in more than 300m water depth supported on very soft soil. The foundation systems represent a major breakthrough for their simplicity, cost-effectiveness, and technical reliability.The Tension Leg Platform (TLP) and the worlds largest Subsea Production System (SPS) are secured to the seabed without the use of piles. Skirted gravity systems are used which have minimized construction costs and installation time. Stricter requirements to removal can more easily be met with these systems. Future subsea wells in the area are planned to be fully protected within subseabed silo structures, minimizing impact on and from the fishing activities.
