The Floating Production Unit (FPU) Visund, is installed east of the Gullfaks
field in the North Sea and operated by Norsk Hydro Produksjon AS. It has the capacity
to produce 16.000/SM3/SD of oil and 10x106 SM3/SD of gas.
The platform is situated directly above completed subsea wells with flexible
risers between wellheads and platform. Stabilised oil is transported through a 14"
pipeline to Gullfaks, for storage and offloading. The Platform is positioned by
hydroacoustics (LBL/SBL) and held in position by 16 anchor lines. KONGSBERG has
also supplied draft monitoring for ballast control.
The Rig Management System includes:
- Posmoor system with simulator, a short baseline hydroacoustic position reference system with four transducers fitted with draft sensors, and a DGPS satellite position reference system
- Vessel control system which performs ballast functions and alarm monitoring
