Cofferdam can reduce noise from turbine installation

摘要

Lo-noise, a company founded by Kurt Thomsen, founder of wind turbine installation company A2SEA, and OSK-ShipTech, has provided Maritime Journalwith details of a new concept for reducing underwater noise levels during the installation of offshore wind turbines. According to legislation from the EU sound emissions from the installation of offshore wind turbines need to be reduced in order to reduce the threat to marine mammals. Until now, little effort has been made to reduce the waterborne noise created when driving monopiles into the seabed, although techniques such as 'bubble curtains' have been used.
