Riffgat - windfarm

Trenching in the winter season in a challenging environment.

Project description:

• Installation and trenching of 33 array cables.

Project challenges:

• The work had to be performed in the winter season.
• Requirement of minimum 1 meter burial depth.
   

Nexans' solution: Capjet ® performed all infield trenching on the Riffgat project in Germany during the winter season 2012-2013. All 33 cables were buried down to 1.5 meters depth and an as-trenched survey was performed by the Capjet ®. The full length from windmill to windmill was protected with the Capjet, eliminating the requirement for additional protection by mattress or rockdumping.   The entire project (installation and trenching) was performed with a single vessel.
