IHC Offshore Systems, part of IHC
Merwede, has been awarded a rental
contract for the Noise Mitigation
System NMS-6900. Dutch offshore
contractor Seaway Heavy Lifting will
operate the NMS-6900 during the
installation of 30 monopile
foundations for the Riffgat offshore
wind farm off the coast of Germany.

The purpose of the NMS-6900 is to
reduce noise caused by offshore piledriving
activities carried out in the oil
and gas and renewable energy sectors.

Advanced technology developed
within the IHC Merwede group
reduces the negative effects of such
noise on sea life.

The system consists of a doublewall
steel screen capable of resisting
harsh offshore conditions such as
current and wave impact. A special
guiding system has been incorporated
to keep the monopile and NMS-6900
concentric.
