DEME Offshore’s DP2 jack-up installation vessel Sea Installer will get a major crane upgrade when the capacity is increased from 900 tonnes to 1,600 tonnes. Being built by crane manufacturer Huisman, the new crane is expected to enable the vessel to handle the next generation of offshore wind turbines.

The upgraded  
Sea Installer will be deployed for the first time at the 800 MW Vineyard Wind 1 project, one of the first large-scale wind farms in the US. Vineyard Wind 1 will feature 62 GE Haliade-X offshore turbines. These units have a 220-metre rotor, 107-metre blades and will be 248 metres high.

Marro Vreys, Business Unit Director Wind Turbine Generators (WTG) at DEME Offshore: “Yet again, DEME is taking the lead and supporting the development of the offshore wind industry just as it has been doing for the last 20 years. We are willing to make the necessary investment in new technology to make sure that our fleet is ready for the future. This allows us to maintain our position as the industry leader in WTG installation and also to assist the offshore wind sector as it looks to take the next step, deploying even more powerful turbines.”


DEME also secured an option to upgrade the crane on jack-up installation vessel
Sea Challenger.
