Applying to all cargo, RoPax, and cruise ships above 5,000 GT, the CII is an operational index based on the Annual Efficiency Ratio (AER).
In simple terms, the Carbon Intensity Indicator (CII) is a measure of how efficiently a ship transports its cargo. Since January, all ships must gather emissions data in order to report their annual operating CII and CII rating. The ship is then given an annual rating ranging from A to E:
A – major superior performance level
B – minor superior performance level
C – moderate performance level
D – minor inferior performance level
E – inferior performance level
SEEMP
Performance level will need to be recorded in the ship’s Ship Energy Efficiency Management Plan (SEEMP), a mandatory, ship-specific document that lays out the plan to improve a vessel’s energy efficiency in a cost-effective manner. The SEEMP will include the Ship Fuel Oil Consumption Data Collection Plan (DCP), which includes a description of the methodology for data collecting and the reporting processes.
Recommendations
DNV proposed the following recommendations for monitoring CII rating:
- Review performance data by collecting data on key performance indicators, such as maintenance records, fuel consumption, voyage reports, and inspection reports. Use this information to identify trends and areas for improvement.
- Conduct regular assessments of your vessels’ operations and performance, including safety inspections, risk assessments, and operational audits. These assessments can help identify potential problems and provide an opportunity to address them before they escalate.
- Engage stakeholders including crew, management and customers in the evaluation process. Encourage them to share their perspectives and experiences and use this feedback to identify areas for improvement.
- Use benchmarking tools to compare your vessel’s performance against industry standards and best practices. This can help you identify areas for improvement.
- Monitor progress regularly and track the results of your efforts to improve your vessel’s CII rating. This will help you determine the effect of selected actions and identify areas where additional efforts are needed.
- Continuously improve and assess your vessel’s operations, processes and procedures. Regularly review and update your safety procedures and incorporate new technology and best practices as they become available.
