Abstract
In this paper, the ship propulsion system is broken down into components to
estimate their individual activities in terms of energy conversion. For common
used propulsion system of merchant ships, the efficiency of each propulsion
component is presented. In the case study, the interaction between all the
propulsion components in energy conversion is investigated by means of
computer model simulation. Based on a selected ferry, the results demonstrate
that, when operating in off-design conditions, the total energy conversion
efficiency is slightly different from that in design condition, whereas, in terms of
the ton-mile specific fuel consumption and energy index, the part loading of ship
and off-design speed of ship scenarios show different impact, but both are much
different from that in design condition.
Keywords: energy conversion, ship propulsion system, off-design operation, tonmile
specific fuel consumption, energy index.
