A2SEA , based in Fredericia, is a Danish company that specializes in technical services in the field of offshore wind energy technology and operates several installation vessels as a shipping company . A2SEA is 51% owned by the Danish utility company Dong Energy (operator of several offshore wind farms) and 49% by Siemens Wind Power (manufacturer of wind turbines and other offshore wind farm equipment).

In mid-2017, an agreement was reached for the takeover of A2SEA by the Belgian offshore service provider GeoSea .

history

The company was founded in 2000. For the construction of offshore wind farms, the cargo ships Ocean Ady and Ocean Hanne were signed in 2001 and 2002 and converted into installation ships according to A2SEA specifications . In doing so, u. a. Retrofitted lifting legs and board crane. In 2002 A2SEA carried out its first project with the Horns Rev wind farm with 80 wind turbines.

In the following years, A2SEA grew continuously through participation in numerous offshore wind farm projects and developed into a market leader in the industry. In 2005, A2SEA bought the two ships mentioned above, previously only chartered, and renamed them Sea Energy and Sea Power . In 2007 and 2008 two more installation ships were added, the Sea Jack and the Sea Worker .

In 2009, A2SEA was bought by Dong Energy. In 2010 DONG sold a minority stake of initially 32.8% in Siemens Wind Power . In the same year this stake was increased to 49%.

In 2010, A2SEA commissioned a fifth installation ship, Sea Installer , which was built according to its own technical specifications and completed at the end of 2012. At the beginning of 2013, the installation vessel was used to build wind turbines in the “Gunfleet Sands III” wind farm, then it was used to build the “ Anholt ” wind farm in the Danish Baltic Sea and “Duddon Sands” in the Irish Sea. In 2012 A2SEA acquired the subsidiary CT Offshore, a company specializing in submarine cable technology .
