Companies should review the placement and labelling of fuel quick-closing valves and assess the operation of fire dampers, advises the Norwegian Maritime Authority. The recommendation comes following a fire on a Norwegian vessel.
During the incident, quick-closing valves were used to shut off the diesel supply to the auxiliary and main machinery. However, the control handles for the quick-closing valves for the emergency generator were located in the same cabinet, leading to the unintended shut-down of the emergency generator.
On the same vessel, handles for closing fire dampers were located within a partially enclosed area. As a result, crew members tasked with closing the dampers had to enter a smoke-filled area, exposing themselves to smoke and requiring medical attention.
The Authority now recommends companies assess and improve the location and labelling of quick-closing valves. More specifically, quick-closing valves for the emergency generator should be positioned separately from those controlling the auxiliary and main machinery. Additionally, it is crucial that the crew members are familiar with the location and operation of these systems during inspections and drills.
Alarm instructions should align with the procedures practised during on-board drills.
It added it advises companies and ship designers to position fire damper controls in a way that minimises the risk of smoke exposure. For existing vessels, it recommends identifying potential risk areas and implementing corrective measures as necessary. During on-board fire drills, particular attention should be given to any areas that may lead to smoke exposure for the crew members.
