A CFD based method to assess underwater venting of methanol and nitrogen for yachts
bookPart
Methanol is a promising alternative fuel for maritime decarbonization, but current safety regulations are designed for large ships and pose challenges for yacht integration. A key issue is the venting of methanol vapours, which creates hazardous deck areas incompatible with yacht design. This study proposes an innovative solution: underwater venting during bunkering. Using CFD simulations in Star-CCM+ with Eulerian Multiphase modelling, we analyze vapor dispersion, dissolution (based on Henry’s law), and safety implications. Results show that underwater venting effectively mitigates risks, ensuring regulatory compliance while enabling safer yacht designs.
