This notice, issued by ABS, summarizes recent observations on bulk carriers where non-compliance with the requirements of SOLAS Chapter XII, Regulation 13.1 was identified in the forecastle space dewatering system manually operated suction valves.
On bulk carriers and in accordance with SOLAS Regulation XII/13.1, MSC/Circ.1069 and IACS UI SC179, the arrangements for draining and pumping ballast tanks located forward of the collision bulkhead and the bilges of any dry space extending forward of the foremost cargo hold, shall be capable of being brought into operation from a readily accessible enclosed space. This enclosed space shall be accessible from the navigation bridge or the propulsion machinery control position without the need to walk across open-deck areas (i.e. exposed free board or superstructure decks).
During recent inspections on two different bulk carriers from different owners/managers, the following cases in forecastle dewatering systems manually operated suction valves were observed:
First case: The suction valve was found in the closed position with a warning sign instructing the crew to keep it closed while in port to avoid accidental discharges.
Second case: A label above the dewatering valve stated: DO NOT OPEN WITHOUT CHIEF OFFICERS PERMISSION.
ABS commented that both cases violate the intent of SOLAS XII/13.1 as they restrict immediate operation of the dewatering system when needed. The valves must remain open at all times.
ABS recommends that the manually operated suction valve of the forecastle space dewatering system must remain in the open position at all times. A clearly visible and appropriately worded warning notice should be posted in the vicinity of the valve.
