Ezra Holdings Ltd.'s subsea construction division, EMAS AMC, has been awarded a contract by ABB, pursuant to an arrangement of strategic cooperation for subsea installation, for the installation of subsea power cables.
This is part of ABB's second contract with Statoil, to supply subsea HVDC Light transmission systems to the Troll A platform in the North Sea.
The Troll A concrete deepwater structure is the world's largest natural gas production platform at 1,552 ft (473 m) tall and weighing 1.2 million tons. It is also the tallest structure ever to be moved by mankind. The platform can produce as much as 120 MMcm of natural gas per day and contains approximately 40% of the natural gas reserves on the Norwegian continental shelf.
The scope of work for EMAS AMC is to install one HVAC subsea cable and two circuits of HVDC subsea cables from Troll A to the land station, Kollsnes. The platform has received power from shore since 2005. The increase in power provided by the new cables will provide power to run two compressor drive systems, which will improve production capacity and extend the lifespan of the platform.
Cable installation operations will be performed during 2Q 2014, using EMAS AMC's Lewek connector. The connector is a newly-built, ultra-deepwater, multipurpose, flex-lay subsea construction and umbilical installation vessel.
