Floating Maintenance Solution

A solution to solve the challenge of major component exchange at the floating wind site, to unlock the potential of floating wind.

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.
