The patent pending Windgrip system – designed and developed by Windcat Workboats – will give advantages in accessibility and versatility on our crew transfer vessels.

The rugged and efficient self tensioning system increases the ability of the vessel to transfer in greater wave heights and reduces fuel consumption whilst pushing on to offshore structures.

The system is Type Approved and features built-in safety and fail-safe systems.

Whilst pushing on in harsher conditions saving of fuel will be made as the force needed from the propellers to hold the vessel against the boat landing will be reduced. The savings can be up to 80% as the engine revs and load can be reduced to give the required grip.

After six months of extensive trials we now have twelve systems installed on our vessels in the offshore wind industry. The system has proven to provide:

  • Increased safety – the additional grip reduces any movement and takes away the risk of the vessel dropping away without warning.
  • Greater access – by adding grip above the vessel’s propulsion, access in higher sea states can be achieved.
  • Fuel efficiency – when gripped on in moderate conditions the propulsion can be reduced resulting in significant reductions in fuel consumption.

The system is easy to operate by the crew of the vessel. The vessel’s master can control the system from the wheelhouse. Emergency stop buttons are fitted on the winches and on the control panel in the wheelhouse.

Whilst using an ROV the vessel is attached to the boat landing reducing movement of the vessel to a minimum allowing for safer craning and deployment of the ROV as well as having a fixed stable position for control and command of the ROV.

During craning equipment from the vessel to the turbine due to the vessel being attached to the boat landing allows for a safer operation due to the reduced movements of the vessel.
