Statoil Statfjord Nordflanken

Norway Block 33/9

Landmark: Utilization of existing field infrastructure to develop hardware

Statfjord Nordflanken was built using an EPC contract for two HOST®, electro-hydraulic control systems with six trees and is configured for an extension to eight wells. Two of the four production wells delivered were transferred to the Sygna project. Flowline and control umbilical were connected to Statfjord C. The HOST® system was used for all the templates. The templates consisted of standard moonpool deployable modules that could be assembled on deck or subsea.
