"Regulation 25-1
Water level detectors on multiple hold cargo ships other than
bulk carriers and tankers
1 Multiple hold cargo ships other than bulk carriers and tankers
constructed on or after 1 January 2024 shall be fitted with water level
detectorsfootnote in each cargo hold intended for dry cargoes.
Water level detectors are not required for cargo holds located entirely
above the freeboard deck.
-
2 The water level detectors required by paragraph 1 shall:
-
.1 give audible and visual alarms at the navigation
bridge, one when the water level above the bottom of the cargo hold
reaches a height of not less than 0.3 m, and another at a height not
less than 15% of the depth of the cargo hold but not more than 2 m;
and
-
.2 be fitted at the aft end of the cargo holds. For cargo
holds which are occasionally used for water ballast, an alarm
overriding device may be installed. The visual alarms shall clearly
discriminate between the two different water levels detected in each
hold.
-
3 As an alternative to the water level detector at a height of
not less than 0.3 m as per sub-paragraph 2.1, a bilge level sensorfootnote serving the bilge pumping arrangements
required by regulation 35-1 and installed in the cargo hold
bilge wells or other suitable location is considered acceptable, subject
to:
-
.1 the fitting of the bilge level sensor at a height of
not less than 0.3 m at the aft end of the cargo hold; and
-
.2 the bilge level sensor giving audible and visual alarm
at the navigation bridge which is clearly distinctive from the alarm
given by the other water level detector fitted in the cargo
hold.
