Preventing engine room fires before small defects become emergencies

BIMCO's Tanker Safety Network convened an online session on 29 October 2026 to discuss preventing engine room fires before minor issues escalate into emergencies. The meeting examined instances where leaking pipes, inadequate insulation, and electrical faults led to serious fires. Previous claims analysis revealed that about 60% of hull and machinery fire incidents originate in engine rooms.

Key incidents illustrated how seemingly small defects, when combined with inadequate protective measures, can escalate into major fires. A replacement fuel connection fitting with incorrect threading allowed fuel to spray onto a turbocharger with insufficient insulation. Another case involved a hydraulic oil leak that went unaddressed for several hours before a fire broke out while the ship was at sea.

An electrical fault in a starter panel, evidenced by a burnt-out contactor and damaged components, was also analyzed, with worn contacts and loose connections cited as potential contributors.

The session emphasized the importance of inspecting various components such as pipe supports, tightening procedures, filter covers, and flexible hoses, as well as restoring insulation and protective arrangements after maintenance. Participants discussed the challenges of inspecting numerous electrical components onboard, suggesting the use of critical equipment identification and planned maintenance incorporation as solutions.

Wider considerations included the availability of suitable spare parts, the time needed for repairs, and the impact of logistical factors like reaching the next port or anchorage on maintenance decisions. Thermal imaging, AI-assisted cameras, and other monitoring technologies were proposed as means to detect hot surfaces and insulation gaps earlier. The effectiveness of these detection methods depended on corresponding response actions, including effective watchkeeping, maintenance procedures, and decision-making.

The discussion also touched on the continued availability of local water mist firefighting systems during electrical supply disruptions, with the issue left for further examination. Additional incidents involving incinerators, tumble dryers, and electrical equipment in accommodation spaces, as well as power bank and lithium-ion battery fires, were suggested for future sessions.

The Tanker Safety Network serves as a forum for members to exchange operational experiences and discuss common safety challenges, encouraging the sharing of lessons learned from their operations.
