Project no: 111

Project name: ABB AB High Voltage Rigid Submarine Cables

Project description: Tekmar Energy - Renewables

Project completion date: May 2009

 

Description of product

 

8-off 80 kNm TEKLINK® Bend Restrictors assemblies

 

StatoilHydro Gjøa links the new power plant at Mongstad, north of Bergen, Norway and Norwegian oil and gas company’s StatoilHydro Gjoa platform in the North Sea. This will be the first floating platform ever to have such a direct power link and as a result will reportedly reduce 250,000 tons of CO2 emissions per year.

 

Bend restrictors for the Gjoa Project, in which ABB are developing a rigid submarine cable joint to be used on a high voltage cable in the North Sea. The joint is approximately 6m in length and 0.65m in diameter. Bend restrictors are required as part of the scope to protect the cables in the subsea environment.

 

Client Requirement

Rigid submarine cable protection system for extended service life.

 

Tekmar solutions

Polyurethane (PU) bend restrictors.

 

Client benefits provided by solution

• Provides complete long term dynamic protection of cable
• Simple and rapid onshore / offshore installation method reducing personnel & vessel time
• Finite design of components and verification of function
• Subsea corrosion resistant
