Description

  • The Visund field is located in block 34/8, about 22 km north of the Gullfaks field on the Norwegian continental shelf.
  • Production is from the Visund Floating Production Unit (FPU)
  • The field initially produced only oil but the platform was altered, a gas pipeline was installed and gas production started in 2005
  • The northern part of the Visund field is developed with a subsea template, about 10 kilometres north of Visund A
  • The water depth at the work sites ranges from 190m to 335m.
  • The oil is sent by pipeline to Gullfaks A for storage and export via tankers.
  • Gas is exported through the Kvitebjørn gas pipeline and on to Kollsnes Gas Processing Plant, where the NGL is separated and the dry gas is further exported to the market.
