Moray First Marine, a marine company based out of Lossiemouth, on the Moray Firth in Scotland recently was successful in locating and recovering lost recording equipment, including a 170kg (375 lbs.) ground weight, in 54 metres (177 feet) of sea water from the Moray Firth, a triangular inlet of the North Sea, north and east of Inverness.
This was achieved using a Videoray Pro 3 GTO ROV fitted with a three jaw grabber and a Tritech Micron Sonar. The recording equipment was lifted onto Moray First's survey/workboat MV Solstice. The ROV Operation saved £1000s for their client, pleasing them that a more expensive dive team was not necessary, gained the ‘lost' data, and proved itself for further recovery operations. It is now planned for further use where Acoustic Releases are not available or for when they fail.
