Scope of work includes six subsea trees, with a possible option for nine further subsea trees, including control systems.

The Troll field is located in the northern part of the North Sea, approximately 65 kilometres west of Kollsnes, near Bergen in Norway. The field contains 40 per cent of the total gas reserves on the Norwegian continental shelf and is also one of the largest oil fields on the continental shelf. Under this contract, Aker Solutions will deliver equipment to the oil section of Troll.

"Having been involved in Statoil's Troll projects from the beginning in 1996, we are proud to still play a part in this industrial milestone. The Troll field represents a cornerstone of Norway's offshore oil and gas production and we are delighted to be awarded such a prestigious North Sea contract," says Alan Brunnen, executive vice president of Aker Solutions' subsea business area.

The Troll field is the world's biggest subsea development with regards to the number of subsea wells. Last year, Aker Solutions reached a major milestone in delivering the 100th subsea tree to the Troll field. The contract awards and deliveries for Troll have helped to shape and develop Aker Solutions' subsea business. 

A subsea tree is a key technology enabling oil and gas production directly from a subsea well to a processing facility. The tree is essentially an advanced set of valves and is used together with associated technologies to control the well flow. The subsea tree is an integral part of a subsea production system. The tool package is needed to operate the fourth rig to be employed by Statoil on the Troll field.
