Troll
Troll is a field in the northern part of the North Sea. The water depth in the area is 300-330 metres. Troll was discovered in 1979, and the initial plan for development and operation (PDO) was approved in 1986, and updated in 1990. Production started in 1995.
A phased development was pursued for the Troll field, with Phase I recovering gas reserves in Troll Øst and Phase II focusing on the oil reserves in Troll Vest.
Troll Phase I has been developed with Troll A, which is a fixed wellhead and compression facility with a concrete substructure. Troll Phase II was developed with Troll B, a floating concrete accommodation and production facility, and Troll C, a semi-submersible accommodation and production steel facility.
Troll Phase III (gas production from Troll Vest) started in 2021.
