OWF Norther Offshore Wind Farm – Trencher launch and recovery

A dynamic lift analysis has been performed for the launch and recovery of the CT1 Trencher using the Roxane-Z for DHLC.

The trencher will used by van Oord for the near shore Burial of the Norther Offshore Wind Farm export cable.

Orca offshore has modelled various stages of the trencher overboarding operation to determine the allowable seastate for the operation and to advise on the best possible procedure to achieve the highest workability.
The system has been modelled in MOSES as a multibody dynamic model to derive the motions and loads of the lift.
