The UK Marine Accident Investigation Branch (MAIB) has called on the International Maritime Organization (IMO) to require thermal imaging equipment for detecting hazardous hot surfaces. This recommendation follows a serious engine room fire aboard the passenger ferry Stena Europe on February 11, 2023.
The fire broke out as the ferry approached Fishguard, Wales, from Rosslare, Ireland, causing significant damage to the main engine room. Although no injuries or pollution occurred, the incident rendered one of the vessel's four main engines inoperable for weeks.
The MAIB investigation revealed that the fire began when fuel ignited on an exhaust surface that exceeded 400°C. Further inspection found damaged or missing protective shielding around the fuel systems on all engines. Exposed hot surfaces, some exceeding 220°C, were identified as critical hazards.
The investigation also unearthed long-standing vulnerabilities in the engine design. Wärtsilä, the engine manufacturer, had flagged potential issues with fuel system leaks as early as 1995, proposing modification solutions. However, only one of Stena Europe's four engines had received the full modification package.
In light of these findings, the Maritime and Coastguard Agency (MCA) is advocating amendments to IMO’s Maritime Safety Committee Circular 1321. The changes aim to mandate thermographic equipment for identifying hot surfaces that could lead to fuel or oil ignition.
Stena Line Ltd has been advised to:
Conduct a full review of their defect reporting systems.
Enhance inspection protocols for onboard equipment.
Equip their fleet with thermal imaging cameras.
Share the details of this incident across their operations to prevent recurrence.
The Stena Europe fire underscores the importance of proactive safety measures in maritime operations. Key issues identified include:
Ineffective fire protection systems.
Delayed implementation of known safety modifications.
Insufficient crew training for engine system inspections.
Inadequate temperature monitoring equipment.
This incident serves as a stark reminder of the need for stringent safety protocols and continuous equipment upgrades. As maritime operations grow increasingly complex, robust measures like thermal imaging can play a vital role in preventing catastrophic failures and ensuring passenger safety.
