On the basis of introducing the background and influence of EEDI(Ship’s Energy Efficiency
Design Index), the concept of ship’s energy saving and emission reduction is highlighted.
Taking an 8, 000-ton offshore oil tanker as the research object, the EEDI calculation formula
of the tanker is proposed and the EEDI result of the ship is calculated. Based on the three
main factors affecting the EEDI-deadweight capacity, main engine power, sailing speed, it
studies oil tanker energy saving and emission reduction, and then provides reference for this
type of ship coltrolling CO2 emission and improving ship’s own performance.
