UK-based First Subsea has installed bend stiffener connections for gas lift and production risers, power cables and umbilicals for ENI Norge’s Goliat FPSO in the Norwegian Barents Sea.
The Goliat FPSO is the first offshore oil development in Arctic region, in the Barents Sea and features 11 Type II bend stiffener connections (BSC) at present.
A further ten receptacle I-tubes have been pre-installed within the base of the vessel.
These pre-installations enable more tie-backs to be added as field witnesses an increase in production.
With no moving parts, the Type II BSC enables a simpler riser, umbilical or cable connection, and has been selected for the Goliat tie-backs.
According to First Subsea, the first Type II BSC comprises a ball and taper connector that are attached to a bend stiffener, which is integrated into a pre-machined I-tube.
The self-energising and self-aligning connector features the company’s automatic release clamp (ARC), enabling diverless and remotely operated underwater vehicle (ROV) less bend stiffener connections.
Located 85km north-west of Hammerfest, the Goliat license is 65% owned by Eni Norge (operator) and Statoil Petroleum (35%).
The field has two main formations including Kobbe and Realgrunnen and two minor formations Snadd and Klappmyss.
