Kongsberg Maritime Launches Advanced Continuous Emissions Monitoring System (CEMS) to Boost Compliance and Fuel Efficiency, Real-time sensor technology empowers shipowners to meet stricter environmental regulations while optimising operational performance
Kongsberg, Norway – 3 June 2025 – Kongsberg Maritime, a global leader in marine technology solutions, today announced the launch of its new Continuous Emissions Monitoring System (CEMS), a state-of-the-art platform designed to provide shipowners and operators with accurate, real-time data on vessel exhaust emissions. The system enables better regulatory compliance, improved fuel efficiency, and strategic fleet future-proofing amid increasingly stringent global emissions standards.
The introduction of Kongsberg’s CEMS marks a major step forward from traditional emission estimation methods by offering sensor-based continuous monitoring of all key greenhouse gases, including CO₂, CH₄ (methane), SOx, NOx, and CO. This revolutionary approach provides comprehensive insights into the combustion process of marine engines, allowing operators to make informed decisions on fuel usage, engine operation, and maintenance to reduce emissions and optimize efficiency.

Monitor. Comply. Optimise: How CEMS Supports Sustainable Shipping
Kongsberg Maritime’s CEMS system integrates seamlessly with its flagship vessel automation platform, K-Chief, providing crews with a unified interface that displays real-time emissions alongside operational data. This tight integration simplifies the monitoring process, reduces manual reporting errors, and enhances overall shipboard efficiency.
Randi Østern, Senior Project Manager at Kongsberg Maritime and lead developer of CEMS, explains:
“Ship owners need to comply with upcoming regulations that are tightening year by year. The key to future-proofing vessels is emissions monitoring, and Kongsberg CEMS delivers the reliable data from sensor to cloud that our clients demand.”
Unlike traditional calculation methods based on fuel consumption and flow metering—which are inherently imprecise and only offer a partial picture—CEMS uses advanced cold dry extractive sensor technology to capture continuous, real-time data on emissions from all combustion sources aboard the vessel. This allows a complete and accurate assessment of greenhouse gas output and helps identify inefficiencies or issues with engine combustion processes.
Why Real-Time Emissions Data Matters
Traditional emissions monitoring techniques typically rely on fuel usage data combined with standard emission factors to estimate pollutant output. This approach, however, can mask changes in combustion efficiency or equipment malfunction that may cause emissions to rise unnoticed.
“If emissions start increasing with the same operational pattern, calculation methods are not able to give any insight into the combustion processes,” says Østern. “With CEMS, we can give the shipowner the full picture — how much of each greenhouse gas is actually in the exhaust and what happened to the fuel in the engine.”
Accurate real-time data enables ship operators to:
- Ensure ongoing compliance with IMO and regional environmental regulations
- Detect and address engine inefficiencies promptly
- Reduce fuel consumption and associated costs
- Plan targeted maintenance to prevent costly downtime
- Support comprehensive decarbonisation strategies
Designed for Easy Installation and Seamless Integration
The modular design of Kongsberg CEMS ensures it can be retrofitted to existing vessels or integrated into newbuilds with minimal disruption. Its compatibility with the K-Chief automation system means that emissions monitoring is accessible through a single control panel, streamlining crew operations and reducing the risk of human error.
Additionally, K-Chief’s remote diagnostics and cybersecurity protocols allow vessel operators and shore-based teams to monitor system performance and address issues proactively, enhancing reliability and safety.
Future-Proofing Fleets with Global Support
With environmental regulations continuously evolving and growing more stringent, operators face rising pressure to invest in advanced emissions monitoring technology. Kongsberg Maritime is positioned to support this transition with its global network of support centers, providing maintenance and technical assistance for CEMS installations worldwide.
Østern adds “Many vessel owners have yet to invest in CEMS but are now considering fleet-wide installations. Our worldwide support network and remote diagnostic capabilities make this a feasible and attractive solution for shipowners focused on compliance and operational efficiency.”
By leveraging real-time emissions data, operational automation, and expert global support, Kongsberg Maritime’s CEMS empowers owners and operators to confidently navigate regulatory landscapes while optimizing vessel performance and reducing environmental impact.
