The Energy Efficiency Design Index (EEDI) is a necessary benchmark for all new ships to prevent pollution from
ships. MARPOL has also applied the Ship Energy Efficiency Management Plan (SEEMP) to all existing ships. The Energy
Efficiency Operational Indicator (EEOI) provided by SEEMP is used to measure a ship's operational efficiency. The shipowner
or operator can make strategic plans, such as routing, hull cleaning, decommissioning, new construction, and so on, by
monitoring the EEOI. Fuel Oil Consumption is the most important factor in calculating EEOI (FOC). It is possible to measure it
when a ship is in operation.
