Dutch company IQIP has been awarded a contract by DEME to deploy its Hydrohammer IQ6 spread for Vattenfall’s Nordlicht 1 and 2 offshore wind farms in the German North Sea.

IQIP’s Hydrohammer IQ6 spread will be deployed together with the PULSE technology, which is a noise mitigation add-on that uses a dual-piston system and a fluid-filled chamber to reduce underwater noise at the source. Its modular design allows seamless integration with other noise mitigation systems, said IQIP.

“Together, we will drive 112 monopiles into the German seabed using our Hydrohammer IQ6 spread with PULSE. Our long-standing partnership with DEME and our shared track record of successful offshore wind installations worldwide form the foundation of this collaboration ,” said Stefan Hansum , Director Europe, IQIP.

DEME will carry out the installation of 112 monopiles and transition pieces under a contract signed with Vattenfall at the beginning of this year.

Germany’s EEW Special Pipe Constructions (EEW SPC) will manufacture the foundations. Production is planned from the end of 2025 to mid-2027. The transition pieces will be supplied by CS Wind Offshore.

“We are proud to partner with IQIP on this landmark project for Vattenfall. Their Hydrohammer IQ6, combined with PULSE®, enables us to install some of the largest monopiles in the industry with great precision and significantly reduced noise ,” said Bas Nekeman , Business Unit Director of DEME North Europe.

Vattenfall reached the final investment decision on the Nordlicht 1 and 2 offshore wind farms in March 2025.
