Njord Capjet w120Project description:

  • Extra protection with specially designed backfill plough.


Project challenges:

  • Protection of a 10" steel pipeline
  • A backfill of one meter was required, in the clayish seabed, to provide weight to prevent upheaval buckling.  
     
Njord-2 Capjet w120 Nexans' solution:
  • The 10” pipeline was buried to 1.5 m with the Capjet.
  • A special backfill plough was developed in record time to provide the extra 50 cm of backfill to meet the requirement of 1 m.
  • A complete backfill run was made along the entire length.
