The contract includes the delivery and operation of the MENCK MHU 4400S hydraulic hammers and the newly developed MENCK underwater Noise Reduction Unit, MNRU, and a live penetration depths measurement system.

The essential hydraulic drive unit and the external shock absorber ring were manufactured and assembled at MENCK’s headquarters in Kaltenkirchen, Germany and mobilised to Rotterdam for integration with the hammer housings and the 220-ton ram weight assembly on the client’s premises.

The handover to the client took place in December and the equipment was mobilised for use offshore in January, MENCK said.

”This contract follows a recent sequence of successful projects in the renewables arena using the largest MENCK hammers,” said Fabian Hippe, Managing Director, MENCK GmbH.

”Besides the general success in renewables and the increase of our market share, it is another significant step forward in our partnership with Heerema.”

Heerema Marine Contractors is currently involved in the construction of Ørsted’s 900 MW Greater Changhua 1 and 2a offshore wind farm.
