Siem Offshore Contractors has announced that all 70 kilometres of inter array grid cables for the Nordsee One Offshore Wind Farm in the German Bight of the North Sea have now been installed, terminated, trenched and tested three weeks ahead of schedule.
All 59 cables were installed using the the Cable Lay Vessel (CLV) Siem Aimery and the Installation Support Vessel (ISV) Siem Moxie. These were supported by a further in-house Multi-Purpose Vessel (MPV) Siddis Mariner, which provided subsea support for the installation of cable protection systems and concrete mattresses.
