Offshore staff

OSLO, Norway -- Aker Solutions has supplied its 100th subsea tree to Statoil's Troll development in the Norwegian North Sea.

Troll is 65 km (40 mi) west of Kollsnes, near Bergen. According to Aker, it contains 40% of Norway’s total gas reserves and is also one of the largest oil fields on the Norwegian continental shelf.

Kvaerner Energy, since subsumed into Aker Solutions, began developing a subsea tree in 1991, and delivered its first consignment to Troll in spring 1997.

Its Tranby technology and manufacturing center remains its main production site for subsea trees in Norway, employing over 500 people.

Of the 100 trees delivered to Statoil, 99 are for oil production while the other is a water injection tree. Thirty-two of the subsea trees are connected to the Troll B platform and the remainder to the Troll C platform.
