Luciana Suman, CEO and Technical Director of Marmec Engineering, has issued a caution regarding the distinct technical properties of ethanol and methanol when used as marine fuels. Her analysis, published as the International Maritime Organization (IMO) revises its interim guidelines for these alternative fuels, underscores that they should not be considered interchangeable. Suman points out that ethanol forms a flammable atmosphere at a lower concentration compared to methanol, a crucial factor that dictates the requirements for ventilation and detection systems on vessels.
This distinction is vital for freight forwarders and vessel operators considering future fleet decarbonization strategies. Misunderstanding these differences could lead to inadequate safety protocols, potentially impacting vessel design, operational procedures, and crew training. For forwarders, this means that the choice of vessel powered by either methanol or ethanol might have implications for cargo insurance, port clearances, and overall operational risk assessments, as different safety standards will apply. It also highlights the ongoing evolution of fuel technologies and the need for continuous adaptation in maritime logistics.
As the IMO continues to refine its guidelines, the industry will need to implement specific safety measures tailored to each fuel type. This will likely influence shipbuilding specifications, bunkering procedures, and emergency response protocols, ensuring that vessels are equipped to safely handle the unique characteristics of their chosen alternative fuel.
