In 2014, DONG Energy announced that the MHI Vestas V164 8.0 MW turbine was the preferred model for Burbo Bank Extension, making it the first commercial site for an 8 MW turbine project. We asked A2SEA’s Hans Peter Johannsen what it takes to load, transport and install these huge structures. Continue reading
In January 2014, six companies got together to test the use of vibration piling as a quieter, faster way to sink monopiles into the seabed. The results aren’t finalised yet, but what’s the current status?
RWE Innogy, E.ON, Dong Energy, Vattenfall, EnBW and Bilfinger Marine and Offshore. When a line-up of companies like this gets together to support an innovative project, you would expect them to make quite an impact. In the case of this pilot project, however, the situation is quite the opposite. Continue reading
We take a closer look at what is perhaps the most crucial piece of onboard machinery in offshore wind installation.
For an offshore wind installation vessel, a main crane is like a carpenter’s hammer: the most important tool in the toolbox. There, however, is where the comparison stops, because SEA CHALLENGER’s main crane is one of the most up-to-date cranes in offshore wind, capable of feats far in excess of anything you can do with a hammer.

At Westermost Rough, A2SEA has been working with Siemens Wind Power’s sophisticated tool for installing single blades at higher windspeeds and with greater safety. It’s impressive-looking, and it works just as impressively, too. Continue reading
Pre-assembly of turbine components in Esbjerg assisted a 25 percent decrease in installation time and a clean safety record for the Kårehamn wind farm project. But that was just the beginning. We asked MHI Vestas Offshore Wind to tell us more about its pre-assembly capabilities today – and its plans for tomorrow. Continue reading
A bird’s eye view of SEA INSTALLER’S optimised and standardised deck layout, which provides a long list of cost reductions, work process efficiencies, and safety benefits.
By Glen Andresen
In the wind turbine construction business, few things are as important as deck layout. Get it right and projects can run more smoothly and safely. Get it wrong and you’re likely to waste time and money through inefficiencies that just seem to compound one another – not to mention putting life and limb at risk. Continue reading
Announcing a new, larger turbine is comparatively easy. Bringing it to market, however, may take as many as eight years to achieve. For 2014, expect to see a rush of new machines variously being hinted at, announced, tested or put into production. Continue reading

SEA CHALLENGER began her journey from the Qidong shipyard in China to Denmark at the end of March. The excitement is certainly growing at A2SEA about the prospect of SEA INSTALLER’s sister vessel joining our fleet of offshore wind installation vessels. Continue reading

SEA INSTALLER shows what she can really do
At West of Duddon Sands, SEA INSTALLER started out with monopiles and transition pieces. Now she has demonstrated what she was originally designed to do: transport no fewer than eight 3.6 MW topsides at a time for installation far from shore. Continue reading
