WIND TURBINE INSTALLATION VESSEL

February 11, 2010

Fred Olsen orders two wind turbine planters

Fred. Olsen Windcarrier as has placed an order with the Lamprell Energy Ltd. shipyard in Dubai for two self elevating vessels for installation of offshore wind turbines. They are set for delivery in May and September 2012 and the contract with the yard includes options for two additional vessels.

The vessels are enhanced GustoMSC 9000C designs with four jackup legs and a large installation crane. The design incorporates important features from in-house experience from offshore wind installation and maintenance work.

Fred Olsen Windcarrier says the governing thought throughout the design phase has been to make the vessels as operable and flexible as possible, to perform the required tasks of loading, transporting and erecting wind turbine equipment offshore. "Open deck space and accessibility achieved e.g. by the crane wrapping around one of the legs, plus the operability of a high performance jacking systems designed for fast and frequent jacking operations as required by the wind industry, are vital key words in this respect," says Windcarrier.

The vessels have an overall length of 130.8 m and breadth of 39 m. They can carry a payload of 5,300 t and offer a deck area of 3,200 sq. m. Crane capacity is 800 t at 24 m.

The vessels will have three Voith Schneider propellers aft and three tunnel thrusters forward and wiill have a transit speed of 12 knots and a DP II dynamic positioning system,

Accommodations are provided for a total compliment of 80 persons.

The helicopter deck is approved for Sikorsky S92A, Super Puma AS 332 L2 (CAP437)

Tor Erik Andreassen, Managing Director of Fred Olsen Windcarrier says: "We are confident that the vessels and their optimized design will contribute to a considerably more efficient installation process for offshore wind turbines. The technical solutions custom designed for the wind industry, providing a wider weather window, will extend the operability, greatly reduce installation time, limit the need for many other vessels and hence reduce overall installation costs. Adding to the vessel efficiency, they will be manned with a versatile multifunctional crew, also drawing on experienced wind installation teams from our daughter company Global Wind Services."

Fred. Olsen Windcarrier as (previously known as Windcarrier as) has its head office in Oslo and is wholly owned by First Olsen Ltd, with Bonheur ASA and Ganger Rolf ASA (listed on Oslo Stock Exchange) as ultimate shareholders. Global Wind Services has its head office in Fredericia, Denmark and is a daughter company of Fred. Olsen Windcarrier.
