How maritime simulation drives sustainable shipping and IMO compliance
The shipping industry faces increasing pressure to reduce emissions and operate more sustainably. A study from Kalmar Maritime Academy at Linnaeus University shows that simulator-based training significantly improves fuel efficiency and reduces CO₂ emissions—helping operators meet stringent environmental regulations.

IMO regulations: A turning point for shipping
The International Maritime Organization (IMO) has introduced strict requirements to cut carbon emissions. One key measure is the Carbon Intensity Indicator (CII), which ranks vessels from A to E based on annual CO₂ emissions. Poorly rated vessels risk higher fees and restricted port access, making emission reduction critical for long-term competitiveness.
University research confirms positive impact
Linnaeus University’s report highlights that simulator training delivers measurable fuel savings. Using Kongsberg Maritime's simulators for over 40 years, the academy integrates Bridge Resource Management (BRM) and Engine Room Resource Management (ERM) into its Master Mariner program. Students receive real-time feedback on fuel consumption, supported by connected bridge and engine room simulators for precise measurement.
Key results:
- 180 participants completed Eco-driving exercises in the past three years.
- Training improves operational awareness and sustainable decision-making.
Case study: Road ferries cut emissions by 11,000 tons
Since 2015, Linnaeus University has partnered with the Swedish Transport Agency to deliver Eco-driving courses for road ferry crews. Over 400 crew members have completed training, achieving:
- 1.5 litres less fuel per trip
- Estimated €2.5 million annual savings
- 11,000 tons CO₂ reduction each year
Passenger ferries achieve 13% fuel savings
Captains operating small passenger ferries in the Stockholm archipelago now complete mandatory Eco-driving courses combining theory and simulator exercises. Findings show:
- Up to 13% fuel savings
- Improved manoeuvring and operational behaviour across all participants
Our research confirms that simulator-based Eco-driving training consistently delivers fuel savings and emission reductions. With hundreds of captains and officers trained, the results are clear—this method will be essential for the industry’s sustainable future.- Jan Snøberg, Senior Lecturer, Linnaeus University, Sweden
Conclusion: Simulation as a sustainability enabler
As the maritime sector adapts to stricter environmental standards, simulation technology offers a proven, practical solution. By combining advanced training with measurable outcomes, shipping companies can reduce emissions, cut costs, and secure compliance with IMO regulations.
By connecting the K-Sim ship’s bridge and engine room simulators it is possible to provide fuel consumption studies.
