Solving the *maintenance challenge* in floating wind

Fred. Olsen 1848 has developed the patent pending Floating Maintenance Solution.

The solution utilizes existing vessels and methods in the industry today and centralizing around a state-of-the-art maintenance crane.

The solution is compatible with most semi-submersible floating structures in the market, with a minimal requirement for modifications on the floating foundations.

The solution grants the flexibility to perform operations across several projects with various types of floating foundations. 

1 Crane mobilisation
2 Crane house mobilisation
3 Crane boom mobilisation
4 Crane mobilised
5 Erection of crane
6 Prepare for blade lifting operation
7 Dismounting old blade
8 Disconnecting old blade
9 Position old blade on to the vessel
10 Pickup new blade
11 Lift new blade into position 1
12 Lift new blade into position 2
13 Lift new blade into position 3

"The present floating wind component exchange solutions are too costly in terms of assets required, downtime of the turbine and available weather windows. We believe the Floating Maintenance Solution will be a game-changer in the market and can enable the industrialisation of floating offshore wind."

- Per Arvid Holth, CEO of Fred. Olsen 1848

State-of-the-art maintenance crane engineered and developed by Huisman featuring:

  • An expandable main boom and a foldable knuckle boom integrated in a compact self-supporting setup, to be transported safely and efficiently.
  • A unique quick connection system, allowing the crane to be deployed in multiple lightweight modules, and such that it can be quickly deployed on any floating foundation prepared for this setup.
  • An all-electric drive system, resulting in high positioning accuracy, low energy use, reduced maintenance, and high reliability.
  • A dedicated energy storage system, allowing the crane’s power supply to come from the turbine’s auxiliary circuits, yet having sufficient energy available for crane operations.
  • Well-known crane technology.
  • Well-known lifting operation.
  • The crane is capable of lifting components up to 150m above the foundation level. Larger versions can be made available when turbines would grow in the future.
