Heidrun TLP: world’s first concrete tension leg platform
The Heidrun field in the Norwegian Sea, at 350m water depth, has been producing oil and gas since October 1995. It was discovered in 1985 by ConocoPhillips, which served as operator for the exploration and development phase. Statoil is now the operator. A total of 76 wells are planned on the main field, including 51 producers, 24 water injectors and one gas injector. The north flank of Heidrun was brought on stream in August 2000.
A significant step forward in deepwater production technology
The field has been developed with the world’s first concrete Tension Leg Platform (TLP), and represented a significant step forward in deepwater production technology.
Aker Solutions began the development for ConocoPhillips began in 1991. The platform was installed in June 1995 and is now operated by Statoil. Scope of work for Aker Solutions on the Heidrun TLP included engineering, procurement, construction and installation of foundations, tethers and TLP substructure. Total weight of the structure is 287 800 tonnes.
