The service includes gathering vessel data and calculating emissions for any vessel. It covers the data basis used to determine Annual Efficiency Ratio values, annual operational carbon intensity indicator values and the related CII rating. The customer receives calculated data for reporting and review of current vessel CII. The service does not include certification.

Calculate, predict and review vessel emissions and CII
Calculate and predict vessel emissions for any vessel to support annual CII reporting and operational planning.
IMO requirements for Carbon Intensity Indicator (CII) mean that shipowners, operators and fleet teams must calculate, review and follow vessel emissions and operational CO2-intensity data throughout the year. The need for calculation support often arises when current operations may affect the year-end CII rating or when operators need a clearer overview of fleet performance and future rating development.
CII ratings influence operational planning
Without clear emissions data and CII forecasts, it becomes harder to assess whether vessels are operating towards a rating of C or above and to react early when ratings decline. We offer calculations of vessel emissions, Annual Efficiency Ratio values and annual operational CO2-intensity indicator data for any vessel, together with predicted CII ratings, fleet overview data and advisory support on fuel consumption and emissions reduction. The service is part of our expertise area Maritime and offshore engineering, and we also offer help for compliance with IMO EEXI requirements.
Challenges
When annual carbon intensity must be documented, limited visibility and weak forecasting make reporting and planning harder.
Limited visibility makes vessel status harder to judge
When operators do not have a clear overview of current carbon intensity status, it becomes harder to see which vessels need closer attention and whether current operation supports the required annual rating.
Uncertain forecasts weaken year-end planning
When future operations are not clearly linked to likely carbon intensity, teams have a weaker basis for planning the rest of the year to achieve a rating of C or above and avoid penalties.
Late identification of low ratings reduces response time
A vessel rated D for three consecutive years or E for one year must submit a corrective action plan in SEEMP Part III. If a likely low rating is identified late, there is less time to adjust operation before that submission becomes necessary.
Benefits
Get a clearer basis for reporting, fleet review and year-end operational planning
Get a clearer fleet overview of CII status
A clear overview of fleet CII status gives operators a better basis for comparing vessels, spotting where follow-up is needed, and using a single set of figures for annual reviews and internal planning.
Plan year end operation with predicted CII data
Predicted CII data helps teams plan operations towards a rating of C or above and assess early where changes may be needed to avoid penalties before the end of the reporting year.
Set charter party speed from predicted CII
Predicted CII figures can be used to establish a maximum allowed speed in charter party descriptions when needed to avoid exceeding a C rating and to document the basis for that limit.
