FATHOMS
Prior to the arrival of the 345 metre Queen Mary II at Invergordon on the Cromarty Firth recently, Fathoms conducted a pre-dredging multibeam swath survey of the entire port area for the Cromarty Harbour Authority. The objective of the survey was to ascertain the depth of water alongside the Admiralty Pier and to check for any hazards to ensure a safe berth.
As a special feature the two cranes are equipped with six axles. Usually, the HMK 260 E features a 5-axle chassis but is designed such that a sixth axle can be fitted if the quay has a restricted load-bearing capacity as is often the case in the Far East. The crane stabilisers have also been adapted to the quay specifications.
Fathoms chose the Reson SeaBat 8124 multibeam system as the best instruments for the task.
