New study reveals fire safety challenges with methanol-fueled ships

A new fire safety study by Survitec has revealed that existing fire-fighting methods used to extinguish machinery space spray and pool fires on conventionally fuelled vessels are inadequate when dealing with methanol-based fires. This follows extensive comparative fire tests on dual-fuel marine engines using diesel oil (DO) and methanol, carried out amid growing interest in methanol as an alternative marine fuel. Our tests confirm that traditional water mist fire suppression mechanisms do not perform as expected on methanol pool fires and methanol spray fires. A completely different approach is required if these ships are to remain safe. ...said Michal Sadzynski, Product Manager, Water Mist Systems, Survitec. Methanol is a methyl alcohol (CH3OH) that burns in a completely different way than hydrocarbon  fuels and has a much lower flashpoint of 12°C (54°F). However, while there are established fire safety regulations and testing standards for diesel fuels, clear test protocols for alcohol-based fuels such as methanol and ethanol have yet to be developed. Methanol fires are far more aggressive than fires involving traditional hydrocarbon fuels. Methanol fires have different physicochemical properties and so they cannot be extinguished as easily or with the same approach. ..stressed Sadzynski.  The Survitec tests found that while ...
