INFLUENCE OF THE ELEMENTS OF THE SHIP PROPULSION COMPLEX ON THE EEOI (ENERGY EFFICIENCY OPERATION INDEX) OF A PASSENGER SHIP TYPE IB

Ginka Ivanova, Iliyan Donev

The propulsion system of the new hybrid ships plays an important role in reaching increasingly higher ments of international regulations on greenhouse gas emissions. Compliance with the Energy Efficiency Operation Index (EEОI) regulation used to calculate the ship”s CO2 emissions is essential, and the match between the ship and the engine and propeller must be done taking the EEОI into account. In this paper, a comprehensive analysis is performed to obtain the relationship between EEОI and system matching parameters such as ship speed, effective power and propeller diameter, reflecting the trend and degree of EEОI when these three parameters change. Regarding EEOI, the lower the values, the better the performance of the ship and since EEOI takes into account the passengers being transported, the more passengers the better the EEOI.
