Siem Wraps Up Nordsee One Inter-Array Cable Project

  • Business & Finance

Siem Offshore Contractors informed that all 70 kilometres of inter-array grid cables on the Nordsee One offshore wind farm in the German Bight of the North Sea have now been installed, terminated, trenched and tested.

All 59 cables were installed using the “Siem Duo” consisting of 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.

Regis Rougier, managing director of Siem Offshore Contractors, said: “It is a pleasure to confirm the successful completion of our first project utilising the “Siem Duo”. Both the crews of the Siem Aimery and Siem Moxie have made us proud by consistently delivering high quality execution while concluding the project ahead of schedule! We are looking forward to the next challenge for our teams and of course the next project for our vessels.”

Harald Poppinga, project manager for Siem Offshore Contractors, added: “It has been a pleasure to be part of this milestone achievement – envisioned in 2013 and delivered in 2016.”

Siem Offshore Contractors was awarded the engineering, procurement, installation and commissioning (EPIC) contract for the inter-array cable system of the Nordsee One OWF in 2014. The 54 WTGs of the Nordsee One project are located 40km north of the island of Juist in water depths of up to 34 metres.
