Abstract

Recent regulatory developments in the maritime industry will hasten the shift in usage of conventional marine fuels like HFO and MDO to a cleaner fuel like Liquefied Natural Gas (LNG) to meet its ambitious target of lowering carbon dioxide and other noxious gases emissions. Efficient use of energy and waste heat recovery and onboard a ship will help the industry meet this target in the meantime. This paper presents the findings from the modelling of a dual fuel marine diesel engine and ORC system cooled by vaporising LNG and simulation using a system engineering software, Siemens Simcenter Amesim 16. Engine manufacturer’s design data is used as inputs to run the ORC systems running on two working fluids, n-heptane and n-octane to derive the net work and thermal efficiency when installed on a LNG-fuelled Platform Supply Vessel. The ORC system running on n-heptane is found to provide an annual fuel savings of 7% with an estimated payback period of 2.7 years, making it an attractive option for shipowners.
