energy efficiency of ships
CII certification will come into effect on January 1, 2023. This means that the first annual reporting on carbon intensity will be completed in 2023 and the first ratings will be given in 2024.
Our goal is to identify and prevent your vessels from receiving poor ratings.
The analysis of liner and tramp shipping services helps us to determine the impact of each journey on your rating. This allows you to price in the costs before you sign a contract. Based on your operation targets, we recommend strategies to actively influence your rating.
minimize the Idle Time
Calculating anything to predict everything
In all previous analyses we have found that the main reason for a poor rating is idle time. When your vessel is not underway, the fuel burnt counts double. Furthermore, the condition of the hull and propeller deteriorates. However, for vessels that have already covered sufficient distances in the rating period, the effect is only marginal.
Guidelines on operational carbon intensity indictors
MEPC adopted related guidelines on the operational carbon intensity reduction factors relative to reference lines. This includes a reduction factor (Z) for the required annual reduction, which will start at 5% in 2023 compared to 2019.
calculation Methods
In its most simple form, the attained annual operational CII of a ship is calculated as the ratio of the total mass of CO2 emitted to the total transport work undertaken in a given calendar year.
Correction factors
Intersessional Working Group is negotiating the need for further consideration of correction factors and voyage adjustments, for use in the CII calculation mechanism.
Reference Line
An operational energy efficiency performance rating should be annually assigned to each ship. The five-grade rating mechanism would be determined by the attained CII and the predetermined rating boundaries.

What We Achieve
With route-based optimization to reduce greenhouse gas emissions, we are continuously improving the ship’s rating voyage by voyage. Based on economic factors, hindcast data, hull condition and machine learned route ratings, you will receive your vessel’s accurate CII rating based on as little as three months of data.
