In order to construct ship energy efficiency operation system and provide guidance for ship
operation and management practice, taking vesel New American as an example, it uses the real
ship data and ship energy efficiency operation indicator (EEOI) formula to calculate and
test from the variable factors of the number of turbochargers, ship speed, loading and
unloading, and oil injection rate of main engine cylinder, as a result of which the
influence of each factor on the ship EEOI is obtained. The results show that, by optimizing
the number of turbochargers, speed, loading and unloading, and oil injection rate of main
engine cylinder, the ship’s fuel oil consumption can be effectively reduced, which provides
reference for future ship operation, energy conservation and emission reduction.
