Acquisition gives EPCI specialist turbine installation capability
Acquiring A2SEA has given GeoSea turbine installation capability to add to its EPCI and foundations expertise

In acquiring A2SEA earlier this year, GeoSea, part of Belgium’s DEME Group, has added to and broadened the range of services it provides in the growing offshore wind industry


Late August saw GeoSea, part of DEME Group, complete the acquisition of A2SEA from Dong Energy and Siemens International Holding BV after the transaction obtained all necessary regulatory approvals. The acquisition was originally announced on 7 July 2017.

Denmark-based A2SEA specialises in installing offshore wind turbines and foundations for turbines. The company has approximately 160 employees and operates the offshore installation vessels Sea Challenger and Sea Installer.

Dong Energy’s executive vice president and chairman of A2SEA Thomas Dalsgaard said he was pleased that the company had found a new owner of A2SEA. He described the company as a pioneer in the industry and one of the leading players in the market for offshore wind turbine installation. “However, owning an offshore wind turbine installation company isn’t within the scope of our core business, and we’ve therefore been looking for a new owner,” he said.

“With the new owner, I feel confident that A2SEA will be in very good hands. GeoSea is in a position to contribute to A2SEA’s continued stable operating results and ensure the continued positive development of the offshore wind installation company. Based on A2SEA’s expertise and track record for installation, we expect A2SEA will still be a key supplier to Dong Energy’s future projects. This transaction won’t change that fact.”

GeoSea’s managing director, Luc Vandenbulcke, said A2SEA “represents a strong and complementary fit with GeoSea’s operations”. With the acquisition of A2SEA, the company will also gain a group of highly skilled and specialised employees.

Mr Vandenbulcke noted that, whilst GeoSea mainly specialises in foundation works and in the engineering, procurement, construction and installation of the balance of plant for offshore windfarms, A2SEA specialises in transporting and installing turbines. “Many times GeoSea has worked on projects where A2SEA later on installed turbines. Our combined organisation will be well positioned to provide a broader range of integrated services and solutions to renewable energy customers,” he said.

Michael Glavind, CEO at A2SEA, said the company was very pleased to become part of GeoSea, which he described as a highly respected contractor in offshore wind. “To both companies, safety is of paramount importance, and we take pride in delivering projects to the full satisfaction of our customers.”

Since its formation in 2000, A2SEA has installed more than 1,500 turbines and 400 foundations. A2SEA recently completed installation of the turbines on the Burbo Bank Extension offshore windfarm and has also been working on the Dudgeon and Race Bank offshore windfarms. Upcoming projects include turbine installation on the Arkona, Hornsea Project One, Horns Rev 3 and East Anglia ONE windfarms.

Shortly after the deal was announced A2SEA confirmed that it would be installing the transition pieces on the Merkur offshore windfarm in Germany and that it was taking on the project for its new parent company. It will use Sea Challenger to transport and aid in installation of the transition pieces.

In 2016, A2SEA said it planned to focus on its core business in future and sell its cable installation and crew transfer vessel businesses. This development saw the company’s cable installation business CT Offshore and its vessels and equipment sold. A2SEA also decided at the time that crew transfer vessels would no longer be part of its product portfolio.
