Kongsberg Maritime CEMS: Continuous Emissions Monitoring for Vessels

CEMS uses advanced sensor technology to measure a wide range of greenhouse gases, including CO₂, CH₄, SO₂, NO, NO₂, and CO, which may be present in the exhaust. This provides accurate and continuous data so that ship operators can ensure compliance both now and in the future. The system allows for comprehensive emission analysis and real-time monitoring which is impossible with traditional methods such as flow metering, which merely calculates emissions based on fuel consumption.

"Calculation methods are to some extent based on manual inputs and are inherently imprecise. In addition, they only give you half the picture. If the emissions start increasing with the same operational pattern, calculation methods are not able to give any insight into the combustion processes. With CEMS we can give the shipowner the full picture," - said Randi Østern, a Senior Project Manager with Kongsberg Maritime who led the development of the system.

Future proofing made easier
Kongsberg Maritime’s CEMS integrates tightly with the company’s K-Chief vessel automation system, which makes it much easier for a vessel’s crew to read and interpret emissions data. A single interface shows operational data along with emissions data. The system’s ability to automate and streamline the monitoring process reduces manual efforts and errors, enhancing overall operational efficiency.

The system also allows vessel owners and operators to make decisions on operational efficiency and thus focus on unexplored areas of cost savings. Real-time maintenance alerts to the crew ensure that any issues can be addressed promptly. This helps maintaining the accuracy of the emissions data and reduces the risk of non-compliance due to equipment failure. The modular design of CEMS is flexible and easy to install, making it ideal for existing vessels as well as newbuilds.

CEMS allows vessel owners to have greater confidence in their maritime assets. As environmental regulations evolve, having a reliable and advanced emissions monitoring system in place ensures that your vessels remain competitive with less stranded asset risk.

Randi notes that most vessel owners have yet to invest in CEMS. “A lot of vessel owners are considering fleet-wide installation,” she says, “and we have worldwide support for this technology.” Any CEMS will require regular maintenance, and Kongsberg Maritime has a global network of support centres that can assist vessel owners. Moreover, with K-Chief integration, diagnostic support can be done remotely with full cybersecurity protocols in place.
