SOLAS Regulation
1.Bulk carriers shall be fitted with water level detectors
a. In each cargo hold, giving audible and visual alarms, one when the water level above the inner bottom in any hold reaches a height of 0.5 m and another at a height not less than 15 % of the depth of the cargo hold but not more than 2.0 m. The water level detectors shall be fitted in the aft end of the cargo holds.
b.In any ballast tank forward of the collision bulkhead required by the regulation II-1/11, giving an audible and visual alarm when the liquid in the tank reaches a level not exceeding 10 % of the tank capacity.
c.In any dry or void space other than chain cable locker, any part of which extends forward of the foremost cargo hold, giving an audible and visual alarm at a water level 0.1 m above the deck. Such alarms need not be provided in enclosed spaces the volume of which does not exceed 0.1 % of the ship’s maximum displacement volume.
2.The audible and visual alarms specified in paragraph 1 shall be located on the navigation bridge.
System description
The system is designed for 115-230V AC main power and 24V DC
emergency power supply. Emergency power supply is from vessel's
emergency source of electrical power.
The alarm panel has been located on the bridge. And for not to be interface with the night vision, the brightness of the visual alarms and indicators can be adjusted by a switch.
The sensor is a capacitive proximity switch. The sensor is based on capacitive principal and will work in any cargo onboard a bulk carrier. The sensor is for use all cargo holds, Fore Peak Tank and Bosun Store
Respective alarm channels on the alarm panel have a manual override switch. The switch is to be operated when the ForePeak Tank is used for ballast in order to avoid unnecessary alarms. Audible and visual alarms are present in the navigation bridge for all corgo holds (pre-alarm and main alarm) any ballast tank forward of the collision bulkhead and any dry or void space any part of which extends forward of the foremost cargo hold.
In addition to cargo hold alarms the system also indicates and gives alarm when there is an open circuit, short circuit, broken wire, earth fault in the water ingress sensor or water ingress sensors cable, processor fault or power fault occurs or if main power supply or emergency power supply should fail.
For the audible alarms there are 2 types. One for pre-alarm (intermittent beeping) one for main alarm (continuously beeping). And also for fault alarms there is an audible alarm too.
There are alarm relays for; upper level alarm , low level alarm , broken wire alarm and short circuit alarm. With potential free contacts for external alarm in addition to 24V DC outputs for external alarm as loop failure, power/system failure, lights and horns.
The system can be delivered for console mounting or with alarm panel and electronics in one cabinet.
