Houlder’s pile lifting equipment has been in action installing monopile foundations during the Horns Revs 3 windfarm installation project.

The lifting tool had been under a rental contract to GeoSea, DEME Group’s specialist in complex offshore marine construction projects.

“As a key member of the supply chain, Houlder’s Marine Equipment business is helping offshore wind clients across Europe with a range of issues,” said Andy Lovell, marine equipment commercial director, Houlder.

He pointed out these jobs have included controlling large jackets and monopiles; designing seafastenings and deck storage for foundations, blades and nacelles and modelling optimised component logistics from factory gate to offshore installation.

Successful installation

At Horns Rev 3, Houlder’s lifting tool successfully lifted and upended 49 6.5m diameter, 690t piles off the coast of Denmark without incident or downtime.

The tool’s remote-control hook-up and release system engages directly with the foundation pile’s flange.

It eliminates the need for additional human intervention, lifting points and straps delivering key safety and efficiency improvements. Once completed, the Horns Rev 3 will generate 406.7MW which is equivalent to the annual consumption of 425,000 Danish households.

Houlder has been an independent design, engineering and equipment supplier for thirty years. Its marine equipment business, based in London and Tyneside, has more recently become a centre of mechanical, marine, electrical and controls engineering.

The company’s lifting tools remain available for hire and can be adapted for specific applications and differing capacities by our inhouse team of specialist engineers.
