Are fibre rope mooring lines the key to a floating wind turbine generator?

As wind energy production moves further offshore, and water depths increase, fibre rope mooring lines from Lankhorst Offshore hold the key to the successful installation of floating wind turbine generator (WTG) platforms.

Can fibre rope mooring systems for floating wind turbines cut costs?

Fibre rope mooring systems for floating wind turbines can potentially reduce mooring costs in half compared to chain systems.

Does a double-rope mooring system improve vibration control of a floating wind turbine?

The novel double-rope mooring system was modeled in OrcaFlex, and the advantages of the double-rope mooring system compared with the original single-rope mooring system for the vibration control of the floating wind turbine platform were analyzed under normal operating conditions and storm self-existing conditions.

Are fibre mooring ropes a good choice for offshore wind projects?

Already proven in several offshore wind and wave energy projects, the fibre mooring ropes provide the flexibility and stiffness needed to ensure a resilient mooring for long-term offshore installations. The mooring rope characteristics of Gama98® Dyneema® DM20® and Cabral 512® PES make them an ideal choice for offshore wind mooring projects.

How does rope pretension affect a wind turbine?

It can be seen from the table that with the increase in the rope pretension, the wind turbine has no obvious changes in the three aspects of surge, heave, and pitch. With the increase in the rope pretension, the vibration amplitude changes within 4% of the aspect of surge and heave.

How does the mooring rope fairlead affect the power generation efficiency?

For the semi-submersible floating platform, the center of gravity is higher than that of the center of buoyancy, and the position of the mooring rope fairlead, therefore, affects the swing characteristics of the platform, which also affects the power generation efficiency of the whole wind turbine system.
