Kongsberg Maritime has launched a Continuous Emissions Monitoring System (CEMS) to provide real-time exhaust emissions data for shipowners and operators.

The system helps owners and operators monitor and control vessel emissions – supporting compliance with increasingly stringent environmental regulations – as well as identify opportunities for operational improvements and cost savings.

It uses sensor technology to provide accurate and continuous measurement of key greenhouse gases, including CO₂, CH₄, SOx, NOx, and CO. According to the global marine technology company, unlike traditional calculation methods based on fuel consumption monitoring, its CEMS offers a comprehensive and real-time analysis of exhaust emissions from all combustion sources, allowing informed decision-making for decarbonisation strategies.

“Shipowners 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,” said Randi Østern, senior project manager at Kongsberg.

It is fully integrated with Kongsberg’s K-Chief vessel automation system, which automates emissions data through a unified interface, while the modular design of CEMS ensures easy installation on both existing vessels and newbuilds. Integration with K-Chief also means diagnostic support can be done remotely with full cybersecurity protocols in place.

In February 2025, Kongsberg Maritime revealed a range of innovative methods designed to industrialise the transportation and installation (T&I) of floating offshore wind turbines.
