Osiris locate fault on the Moyle Interconnector 

Osiris Marine Services performed diving and remotely operated vehicle (ROV) services on the Moyle Interconnector to attempt to locate a fault within the subsea HVDC interconnector.

Utilising the DP1 barge, the Atlantis, with a dredging and mass flow excavation tool, full diving spread and ROV teams, Osiris undertook deburial, fault investigations, POPIE and TSS fault location.
