Mammoet selects winner of offshore wind innovation challenge

The 5th offshore wind innovation challenge final has concluded, and Mammoet has announced the winner.

This Mammoet-sponsored challenge sought solutions for safe and efficient load transfer between two floating vessels, as well as methods to reduce the cost of turbine maintenance, as turbines become higher and move further away from the coast.

The two finalists presented their concepts in front of a packed audience at Mammoet’s Conbit facility in Eindhoven, The Netherlands, in front of a panel of prestigious judges from Offshore Wind Innovators, Mammoet, Conbit, Shell, and Siemens Gamesa. SkyLifter and Seaqualize then spoke to the audience.

SkyLifter is a solar-powered air crane that can lift payloads vertically beyond the capabilities of even the largest helicopters. It is a lighter-than-air vessel with a lenticular aerostat and an underslung pod that can maintain a geostationary position with minimal energy expenditure.

Due to the maximum reach of available crane vessels, SkyLifter naturally removes height barriers currently in place for turbine maintenance. It can lift up to 250 tons and maintain nacelle components and even blades over a 2,000-kilometer range.

Up to a significant wave height, the Seaqualize Delta transforms any standard heavy lifting crane into a high-performance active heave-compensated crane. This improves the reliability of operations like floating transition piece installations, feeder barge lifts of delicate components like turbine nacelles, and even feeder barge to floating heavy lift vessel transfers.

So much so that during feeder barge operations, it can provide over 80% more workability during the winter months, greatly expanding the work envelopes and thus keeping expensive specialist vessels busy. Its full passive load control ensures smooth motion with no accidental lift-offs or re-hits, making the workplace more productive and safer.

Seaqualize was announced as the winner after a period of deliberation by the judges. They will now work with Mammoet to further develop the solution.
