A2SEA buys offshore wind installation vessel

A2SEA has signed a US$139 million contract with Chinese COSCO Shipyard Group Co Ltd for the construction of a new vessel specially designed for the purpose of installation of offshore wind turbines.

A2SEA is a provider of installation services for the construction of offshore wind farms.

The offshore wind turbine installation vessel is expected to be delivered in the second half of 2012 and have the name SEA INSTALLER.

It will be a jack-up vessel optimised to operate at water depths of up to 45 m.

"An increasing number of offshore wind projects in the near future will lead to even higher demands for installation vessels than already seen today. With a new state of the art vessel, A2SEA will be able to meet our customers' future demands and hold on to our position as the leading supplier of installation services," says Jens Frederik Hansen, CEO at A2SEA.

A2SEA is currently owned by DONG Energy. On 29 June it was announced that Siemens will become a shareholder in A2SEA through subscription of new shares. Closing of this agreement is expected in Q4 2010.
