Base Unit - EEOI Calculation

The Energy Efficiency Operational Indicator (EEOI) has a primary role among the mandatory measures to reduce emissions of greenhouse gases (GHG) -and in particular of CO2- in international shipping.
The indicator of operational efficiency allows operators to measure the fuel efficiency of a ship in operation.

Expressed in grams of CO2 per ton mile, the indicator allows to comparie each vessel to facilitate the adoption of measures to reduce energy consumption.

The result of the calculation is a number that represents the amount of CO2 emitted per unit of cargo and nautical mile.

The EEOI therefore allows to measure the energy efficiency of ships in every voyage or for a certain period of time, to help ship owners and ship operators to evaluate the operating performance of its fleet.

As the amount of CO2 emitted by ships is directly related to the consumption of fuel oil, the EEOI can also provide useful information on the performance of a ship with respect to fuel efficiency.

The EEOI allows continual monitoring of individual vessels in operation and thus the results of all technical modifications.

The NetWave System provides to perform the calculations necessary for voyage or period of time, but also provides an effective and clearer presentation of the data, to allow a better interpretation in function of the operating conditions of the ship.
