Sharing knowhow in offshore wind construction

Quicker and quieter

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

SEA CHALLENGER’s main crane

We take a closer look at what is perhaps the most crucial piece of onboard machinery in offshore wind installation.

THE MOST IMPORTANT TOOL IN THE BOX

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.

Perfecting pre-assembly

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

Standardised, optimised layout brings slew of 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

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
