Key findings
The report provides an in-depth analysis of the challenges and opportunities relating to three critical operations:
- Heavy lift maintenance: the relative motion of the turbine versus the maintenance vessel is a key risk and current heavy lift vessels, originally designed for the oil and gas industry, are not able to lift to the height of a 15MW turbine.
- Tow-to-port: better solutions to safely disconnect and store all the connections when bringing the turbine back to port were researched, providing recommendations depending on the turbine platform design and the distance to port.
- Mooring in challenging environments: both very deep and very shallow waters come with inherent challenges for anchoring floating offshore wind platforms, from selecting the most cost efficient mooring system, to mitigating the strong dynamic motions of waves experienced in shallow waters.
