CII INDICATOR
Reach your ideal* CII and perform beyond compliance
Close performance gaps, reduce emissions, and stay ahead of your target. Continuously monitor, adjust, and optimise your CII performance with confidence.
*) Ideal CII represents the vessel’s achievable carbon intensity based on its technical and operational potential—if key inefficiencies are addressed.
Identifying the inefficiency
Continuous monitoring showed that the vessel’s carbon intensity was trending above its expected trajectory, putting its year-end CII rating at risk.
Understanding the drivers
Further analysis linked the performance gap to a combination of operational and technical factors, including suboptimal trim, speed variations, and engine settings.
By comparing attained CII with ideal CII, it became clear how much of the deviation was driven by operational patterns versus correctable technical inefficiencies—providing a structured basis for prioritisation.
From insight to action
Based on these insights, targeted measures were implemented across key areas.
Operational adjustments—such as improved speed and trim practices—were combined with technical fine-tuning to close the gap between current and ideal performance. Scenario-based CII forecasts were used to validate that the selected actions would support the desired year-end rating.
Delivering measurable results
The implemented measures reduced fuel consumption and carbon intensity, improving the vessel’s projected CII outcome.
More importantly, the crew and onshore teams gained forward-looking visibility—enabling them to actively manage performance throughout the year rather than reacting to year-end results.
Key takeaways
This case highlights that CII performance cannot be managed retrospectively.
Achieving a target rating requires continuous insight into both current performance and future scenarios. By combining attained, ideal, and forecast CII, it becomes possible not only to explain performance—but to actively steer it.
