Waste Material Grapple Recapture with ROV - Case Study
The Carillon power station is a run-of-river power station. The waste material grapple fell upstream from unit 4 after the breaking of its steel wire rope. The use of the ROV allowed work in simple access mode to the installation with a short time of set-up. Only 2 units were stopped instead of 5 with the divers method. Stoppage of more than 2 units at this particular time would have resulted in a waste of water.
