In a certain laden ship a position somewhere near quar ter of the ship s length from the stem is found to give satisfactory results With ships making long voyages in ballast however such as oil tankers because of the light draught forward an after position about three quarters of the ship s length from the stem is often most suitable is recommended to install the transducer on or off the keel line between 600mm and 900mm from the keel to minimize the effect of aerated water Siting near obstructions such as the forward propeller bow thruster water intake pipes and Speed log sensor should be avoided Select a place giving a minimum mechanical vibration Do not lay the transducer cable near or in Parallel with other electric cables extend the transducer cable junction box and an optional shielded 3C Cable ex 660V DPYCS 2 0 are required When the transducer cable length exceeds 100m a matching box is required instead of junction box It should be i installed as near the transducer as possible It is recommecnded to enclose the transducer cable in conduit or pipe for waterproof purpose and electrical shield The conduit should be secured on the upper section of the thru hull pipe The pipe should run above the water level when the ship is fully loaded The top end should be finished with filling compound Apply seal tape to the threads of pipe for watertightness Also apply filling compound to the end of
