Abstract Only about 50% of the total energy available in the fuels onboard ships turn into useful power, either for propulsion or electricity generation, the rest is lost to the environment as waste heat. To meet IMO’s ambitious initial strategy to reduce the greenhouse gas emissions from international shipping by at least 50% by 2050 compared to 2008 levels, several options are available, which include alternative fuels, energy efficiency measures and speed reduction. While the use of alternative fuels like LNG in marine engines had been widely discussed due also to tightening environmental regulations (e.g. IMO sulphur cap 2020), there is comparatively lesser coverage on energy efficiency measures, in particular, waste heat recovery technologies. Waste heat recovery technologies involve the re-use of energy that would otherwise be wasted from marine power plants and could promote efficient use of energy, thereby reducing CO2 emissions. This talk will provide an overview of the key waste heat recovery technologies already available in the market as well as those under research and development. Examples of actual maritime applications will be highlighted to give a sense of technology maturity and economics.
About the Speaker Ng Chun Wee is a PhD student under the supervision of Associate Professor Ivan Tam at Newcastle Research and Innovation Institute (NewRIIS) which is Newcastle University’s new cutting-edge research facility in Singapore. His research interest covers energy efficiency and waste heat recovery onboard ships and how system modelling and simulation methods can be applied to enhance their performances further. Chun Wee graduated with a BEng in Marine Engineering from Newcastle University 15 years ago, and now he is also working as a senior engineer in DNV GL Singapore responsible for plan approval of ships and offshore rigs. Chun Wee has since then obtained MSc in Maritime Studies and Offshore Technology from NTU and NUS respectively. He is a UK Chartered Engineer, and he is also an active member of the Institute of Marine Engineering Science and Technology (IMarEST)
