A solution to solve the challenge of major component exchange at the floating wind site, to unlock the potential of floating wind.
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.
Features & benefits of the Fred. Olsen 1848 Floating Maintenance Solution
- O&M activities carried out on site with no need to disconnect the foundation and tow to port
- Based on proven technology and methodology
- Positioned on the floating structure, the O&M crane operates with the same motions as the floating foundation
- No dynamic lifts performing the component exchange
- Design agnostic and compatible with most semi-submerged floating structures
- No modifications needed on the tower or WTG
- Minimal modifications to the floating foundation
- Builds on market leading competencies of the Fred. Olsen related companies
- In-field deployment of the crane can be done by a regular Offshore Support Vessel that is typical for oil & gas operations.
- The opportunity to perform blade installations using the same crane during the construction phase of a project
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.
