Real-Time cabled ADCP frame recovery from the EMEC tidal energy test site in Orkney.

Here we see a timelapse recording of the recovery of a fixed ADCP frame made for the Teledyne RDI Workhorse Monitor ADCP.
The vessel, C-Chariot, is kept on site using a dynamic 4-point mooring system allowing the vessel to position itself exactly where is required using the winches to alter the vessels position. A drop camera gave vision of the frame on the sea bed 35m below and also as it was lifted, with the vessel keeping station right through the tidal cycle with speeds up to 8 knots.
