The Water Ingress
Detection System is suitable for fitting in bulk carriers, to comply with
SOLAS chapter XII Regulation 12-13, also IACS Unified Requirement S24
respecting Hold, Ballast and Dry Space Water Ingress Alarms.
The system meets the requirements of the IMO Performance Standards for
Water Level Detectors (Annex 5, Resolution MSC145(77)) adopted by MSC77
on 5 June 2003.
The Water Ingress
Detection system is a complete electronic device utilising current
technology, constructed for detection of water solutions and other
conductive liquid mixtures. It is constructed to operate under all
seagoing conditions.
Detection of ingress
of water is achieved by measuring conductivity, through sensor
electrodes. Each alarm zone corresponds to a particular visual display
with a red light (LED), in the front of the panel, that indicates the
zone. The visual display and the additional visual and audible display
are also activated simultaneously. Alarm conditions, acknowledgement
status, sensors failures are transmitted via serial interface to the
Voyage Data Recorder or another control system. Signal for initiation of
dewatering operations in accordance with SOLAS XII/13
- Robust 316L
stainless steel sensing probe with sensing electrodes protected from
mechanical damages and IP68 protection level.
- No floater or other
mechanical devices required: no moving parts.
- Easy installation
and maintenance.
- Automatic sensor
cable fault detection is provided.
- Built in test
facility.
- Alarm overriding
for holds and tanks which are used for water ballast is provided with
automatic reactivation of the alarm after de-ballasting.
- Each input channel
contains a time delay based on sum filter in order to avoid activation
from random spray of the sensors from conductive liquids or interferences
on the sensor cable. This protects against false alarms and prevents the
unnecessary operation of other machinery, for example bilge pumps.
- Two sources AC 220V
50/60Hz and DC 24 V Power supply with main power failure alarm function.
- Includes built-in
buzzer and flashing lights (LEDs).
- No danger of
electrocution, either from the detector cable or from any other external
part of the system. - The system is intrinsically safe.
- Protection from
faulty connection is provided.
- Capable of being
connected to repeater for additional visual and audible indication via
dry contact relays and to other control systems or Voyage Data Recorder
via serial RS485 interface.
