World champions in smooth-running projects

A2SEA provides offshore wind transport and installation solutions at a wide variety of locations. We specialise in providing the offshore wind industry with safer, sustainable, and more cost-efficient operations − through know-how, seamless integration of installation and service solutions, and quality of performance.

As a specialist in offshore wind, A2SEA  fulfills an important role in the offshore wind energy supply chain. To date, A2SEA has the lion’s share of this market, installing nearly 50% of the world’s total offshore wind turbine capacity. We have two specialised installation vessels and a number of smaller crew boats, and can be considered to be a combination of a shipowner and a project organisation. There are around 180 employees, of which around 65 work in office settings, while the remainder are maritime staff at all levels.

A2SEA is owned by DONG Energy, as the majority shareholder, together with Siemens Wind Power. A2SEA is headquartered in Fredericia, Denmark, with subsidiaries in Hamburg and London as well as site offices in the UK.

With over 1,500 turbines and 400 foundations of experience, we’re experts at making fast, well-informed decisions to ensure your project is delivered on time, on budget. Every time. You’ll find, too, that the earlier you involve us in your planning process, the smoother your entire process can be from start to finish.
