The Deep C® ROV Trenching Skid is a highly cost efficient solution for trenching of umbilicals. The trenching system is skidded to any WROV, and requires only hydraulic from ROV to operate. Two swords with jetting nozzles are lowered on each side of the umbilical, flushing the cable down to desired soil depth. The Deep C ROV Trenching Skid requires no deck space or manning, and is very easy to mobilise.
