Wind energy – DolWin6
Rohde Nielsen assisted Nexans with installation of 10 concrete mattresses on 5 cable-crossings for the future cable DolWin6 which runs approx. 45km offshore from the Island of Norderney in Germany.
The installation was executed with DP2 multipurpose vessel Heimdal R equipped with an active heave compensated wire crane and ROV-support to conduct cable-tracking of the existing cables prior to mattress installation.
