Master Marine wins $100 million wind farm installation contract
A $100 million plus installation contract just awarded Norway's Master Marine ASA underscores the fact that wind power projects are set to be an increasingly important part of the offshore services market.
Master Marine has been awarded the contract for the installation of the Sheringham Shoal Offshore Wind Farm.
The wind farm, which will be the U.K.'s fourth largest, is being developed by Norway's StatoilHydro and Statkraft. Its location is in the Greater Wash, approximately 9 miles (17 km) north of the town of Sheringham, Norfolk, U.K. Total investments are estimated at approximately NOK 10 billion (about US $1.5 billion).
It will consist of 88 turbines and is planned to start production in 2011. When fully operational, its annual electricity production is expected to be around 1.1TWh, enough energy to power around 220,000 U.K. homes.
Master Marine ASA's contract, worth an estimated €78 million (about $103 million) covers the planning and installation of 88 wind turbines and two substation modules and was awarded the company after strong competition from other installation contractors.
Master Marine is a Norwegian offshore service company specializing in the transportation and installation of heavy heavy structures for the oil and gas industry. It has two new "Service Jack" jack up construction vessels being built by Drydocks World, Indonesia (the former Labroy Offshore). These vessels--which are like liftboats on steroids-- are fully self contained and are able to install offshore structures with weights ranging up to 7,200 t, replacing the need for several barges, tugs, crane- and accommodation vessels normally associated in offshore field development.
Master Marine says they are less weather sensitive than any competing technology for offshore load transfer operations.
The first vessel, which was awarded a three year contract with Conoco Phillips in October last year ConocoPhillips Scandinavia for the Ekofisk Renewal Project., will be delivered Q1 2010, and the second vessel, which has been awarded the contract for the Sheringham Shoal Windfarm Installation will be delivered Q3 2010.
