Seatrench performed trenching of the Normandie 1 power cable in France and Jersey for VBMS.

Seatrench has completed trenching of submarine power cable in France and on Jersey. In very difficult tidal conditions, a power cable was buried using Hermes IV and the new diverless trenching machine for shallow water. It was decided by French authorities that it was not allowed to dive during operation, and trenching support vessel Hermes IV and a semi remote operated trencher was prepared for the job.

The new diverless trenching machine can start dry from the beach or be launched from Hermes IV. It has the same powerfull trenching capabilities as our previous machines while satisfying the demands of the customers for diverless solutions for shallow water..
