Safety of the hoist unit
・
Ship speed resistance
When using the hoisting device, be sure not to exceed the following ship speed
resistance of the hoisting device. When used in excess of the ship speed
resistance, the hoisting device may be damaged and cause an accident.
Ship speed
resistance
18 knots
・
Change electrolytic corrosion-preventing zinc plates annually.
Be sure to perform electrolytic corrosion prevention. If electrolytic corrosion
prevention is not performed, the transducer may fall accidentally or there may
be an influx of seawater into a dome, in the worst case.
For the transducer
The transducer of this sonar system is filled with castor oil inside. This castor
oil may steep from the transducer cable due to outside temperature change,
but it does not affect the performance.
For preventing damage at sea
When the transducer or the hoisting device is damaged at sea, the sonar
system cannot be used, accordingly, the operation or safe navigation is
sometimes hindered. Furthermore, it takes a large amount of time and c ost to
exchange and repair the transducer or the hoisting device.
In order to prevent these accidents from occurring, store the transducer by
performing the following operations when conditions are as described below.
1. Condition
1) Sea condition with many float and drift
2) The case of getting out of an encircling net by a lightship of round haul
netter fleet
3) A shallow place where ropes or wires are set up under seas
4) During an anchorage of a ship
