Houlder Pile Lifting and Upending Tool


RETURN TO WORK


Houlder’s lifting equipment is returning to work thanks to a new rental agreement with GeoSea, DEME Group’s specialist in complex offshore marine construction projects


James Russell, Houlder’s Marine Equipment Director explained: “Houlder’s marine equipment business stream has been working with windfarm developers and contractors to develop a range of lifting and handling equipment. Our lifting tool has been designed for safer and faster offshore windfarm installation operations.


“The remote controlled hook-up and release system engages directly with a foundation pile’s flange. This eliminates the need for additional lifting points or straps – the optimal solution where the lifting point overhangs the deck of the installation vessel or is out of reach.


“For the current project the tool will be configured to lift 6.5m diameter monopiles at 690t. Options are available for larger and heavier piles in future.”


HORNS REV 3 WINDFARM The tool will be deployed for the installation of Vattenfall’s Horns Rev 3 windfarm off the coast of Denmark. Horns Rev 3 will consist of 49 wind turbines with a total capacity of 406.7MW. It will generate power equivalent to the annual consumption of 425,000 Danish households.
