Safe and efficient DESMI mag-drive centrifugal pumps enable leakage-free methanol fuel systems for ships, reducing vessel carbon emissions and climate impact.
With every year that passes, emission regulations tighten in the shipping industry. Shipowners who want to stay in business need to look for ways of reducing carbon emissions to comply with the targets defined in the IMO GHG Strategy and other regulations.
Running on alternative fuels is one of the most effective ways of reducing emissions. Methanol provides several key benefits as a shipping fuel, making it one of the most promising alternative fuels: When produced from biomass, green hydrogen, or other zero-emission sources, it enables neutral well-to-wake carbon dioxide emissions. And because methanol stays liquid at ambient temperature and atmospheric pressure, you do not need to invest in complex high-pressure or low-temperature systems to use it.
However, methanol is also toxic and highly flammable which prompts safety considerations when selecting and installing a fuel infrastructure for ports and ships. Specifically, you need to make sure that the fuel system is absolutely leakage-free to avoid hazardous situations.
DESMI’s new mag-drive centrifugal pumps are the perfect match for a methanol fuel system: They combine the high efficiency and robust reliability of centrifugal pumps with a magnetic coupling which eliminates the traditional shaft seal solution in the pump. As the pump chamber is thus completely sealed, there is virtually zero risk of methanol leakage. While the magnetic coupling is a new feature on DESMI centrifugal pumps, the technology itself is not new to DESMI.
The DESMI mag-drive centrifugal pump is ideal for methanol fuel systems on new-built dual-fuel ships and can also be retrofitted on existing vessels. It is part of DESMI’s complete portfolio of marine pumps which covers a wide range of applications.
