It has been designed for safer and faster offshore wind farm installation operations.  The remote controlled hook-up and release system engages directly with the foundation’s flange. This eliminates the need for additional lifting points or straps – the optimal solution where the lifting point overhangs the deck or is out of reach (pictured.)

It is a self-contained system with rechargeable hydraulic and electric supplies. Recharging is carried out at a deck-mounted docking station, avoiding the need for additional connections or power lines during lifting operations.

The use of high strength steel provides a robust and lightweight structure with clear and easy access to all inspection and maintenance areas. The control system ensures both simplicity of use, as well as fail-safe operations.
