ECHO SOUNDER
During the PSC Inspection, it was noted that the echo sounder has been found inoperative.
Under normal propagation conditions, the echo sounder should be capable of measuring any clearance under the transducer between 2 meters and 400 meters. Additionally, it should provide a minimum of two range scales one of which, the deep range, should cover the whole range of depth, while the shallow range one should cover one-tenth thereof.
In the cases where the echo sounder might be inoperative, the Owners / Managers should contact RO or flag state representative to obtain a dispensation letter issued by the ship’s Flag Administration for a specific timeframe.
