Liquefied gas (LNG) is expected to become a widely used fuel for
shipping in the near future and the implementation of waste heat recovery (WHR)
units is an effective method of attaining fuel savings. The organic Rankine
cycle (ORC) power system represents a viable technology to be implemented on
board vessels as a way to convert the main engine waste heat into useful power.
Previous investigations have shown that, depending on the case study, fuel
savings in the range 6 – 10 % can be obtained.
With the purpose of deriving guidelines for the optimal integration of
ORC units on board LNG-fuelled vessels, several student projects can be carried
out. The projects could be connected, but not limited, to one of the following
integration of ORC units on board vessels equipped with exhaust gas
recirculation (EGR) unit – case study in collaboration with MAN Diesel &
of data-driven models to simplify the optimization of ORC units;
production of power and cooling for fishing vessels;
of the prospects for waste heat recovery on board two-stroke and four-stroke
design and control of an intermediate oil loop to transfer the waste heat from
the exhaust gases to the ORC unit;
