How to improve your Carbon Intensity Indicator score?

The official explanation goes as follows: The Carbon Intensity Indicator (CII) measures the efficiency with which a ship transports goods or passengers and is expressed in grams of CO2 emitted per cargo-carrying capacity and nautical mile. In layman’s terms, CII is a rating of how efficiently and environmentally friendly a ship is operated.

There are a lot of abbreviations to remember in 2022: EEDI, EEXI, CII, SEEMP, EEOI, and so on. I’d like to concentrate on CII in the following sections (Carbon Intensity Indicator).

According to a recent IMO report, a layer of slime as thin as 0.5 mm covering up to 50% of a hull surface could result in a 25-30% increase in GHG emissions.

Furthermore, it affects the majority of the other tools available to help you improve your CII rating. Speed reduction, route optimization, and other measures will have less of an impact if your hull is not properly maintained.

Proper hull maintenance will be required to get the most out of your efforts to obtain a good CII rating.

What are the best practices for hull maintenance?

In general, if you don’t look, you won’t know. This means that if you don’t inspect your ship regularly, you won’t know how biofouling is developing on your hull.

You can expect the following benefits from performing regular inspections and hull cleaning, before the biofouling covers your entire hull and grows into your anti-fouling paint:

• You will reduce your fuel consumption and, as a result, your CO₂ emissions
• You will protect and possible extend the life of your anti-fouling system.
• You will get the most out of your other emission-cutting activities.
• You will help reduce the risk of invasive species.
• You will significantly reduce the cost of operating your ships.
