New emission monitoring solution helps the maritime industry achieve decarbonisation targets The launch of ABB’s CEMcaptain will help shipping comply with the sulphur emission regulations that were enforced in 2020, and keep in check their CO2
footprint.
In January 2020, the low sulphur and nitrous oxide emission limits in the International Maritime Organization regulations became effective worldwide. CEMcaptain is a powerful emissions monitoring system from ABB designed to help the maritime industry meet these new regulations and become more sustainable. Its measurement and digital capabilities increase on-board safety, provide process optimisation and substantially reduce ownership costs. By consistently achieving 98 percent and more uptime, the new system not only requires less maintenance effort but also saves time otherwise spent on handling non-compliance issues.
Designed with busy mariners and a regularly changing crew in mind, CEMcaptain is a multi-component analyser system that continuously provides real-time data offering reliable measurement of emissions with the highest stability. Operating in even the harshest of conditions it integrates analyzer modules and sample handling components in a standalone cabinet, making installation easy.
Equipped with ABB’s renowned Uras26 non-dispersive IR gas analyser, CEMcaptain simultaneously and continuously measures sulphur dioxide (SO2
continuous CO2
) and carbon dioxide (CO2 /SO2
) in line with regulation requirements. Each analyser has two separate gas paths to allow for measurement of separate streams, with up to four different components per analyser module.
“Our solutions are driving the evolution of sustainable shipping, paving the way to a zero-emission marine industry. ABB has more than 60,000 Continuous Emissions Monitoring Systems (CEMS) installed in over 100 countries that help monitor our environment,” said Stephen Gibbons, ABB’s Head of Product Management in Continuous Gas Analysers. “We draw on 60 years of experience in emissions monitoring to provide this support in concrete terms. CEMcaptain has been combined with innovations in on-site and remote digital services. The result is a solution that provides the industry with a digital toolbox that increases regulatory compliance and operational efficiency.”
Fast fault reporting, diagnosis and repair are achieved via the on-site and remote digital services which help operators get closer to 100 percent availability for their gas analysis instrumentation. Dynamic QR codes are integrated into the ABB CEMcaptain system display panel. All relevant diagnostic information can be collected from the analyser via a scanned code and transferred to ABB support. This means that maritime instrumentation technicians can send real-time information to an ABB service expert to get immediate guidance on appropriate maintenance. ABB Ability™ Remote Assistance with secured connectivity direct to ABB support is also offered for real-time solutions to problems. These features reduce the costly training of changing crews as well as the number of experts required on board. They also increase on-board safety by reducing crew exposure to emissions.
CEMcaptain GAA610-M is approved by all major classification societies (DNV GL, ABS Group, Lloyds Register, Bureau Veritas, ClassNK, Korean Register). For More Info, email:

Personal Exposure Monitoring As the TWA and STEL values are so low, the requirement for nitrogen dioxide calibration gas for personal exposure gas monitoring has typically been either 5ppm or 10ppm. Nitrogen dioxide has been a challenging gas for many users of gas detection instruments as the highly reactive gas has an extremely short shelf life in smaller non-refillable cylinders (7 months). This creates issues with having the gas readily available for immediate requirements.

Smaller cylinders of 34L, 60L or 112L have been the norm for this application primarily because of the short shelf life. In most cases, customers ask for the smallest cylinder because of the shelf life.
Fortunately, CAC GAS & Instrumentation has two solutions available today which can assist in solving this issue.

providing flexibility for measuring other gases. Although an initial capital cost is required, they are very cost effective over time and provide a long-term solution. The electrochemical cell can be stored when not in use providing customers with NO2

The 36-month shelf life “white top” specialty gas mixture cylinder is an excellent solution for those customers with multiple instruments. High pressure cylinders are available in larger capacities of 900 and 4000 litres of gas. These cylinders are specifically treated and conditioned to provide stability over this extended shelf life. Based upon using only two litres of gas per monthly calibration, a customer would only need to have 10 instruments to consume 900 litres within the shelf life. That does not include bump testing/response testing which should be done daily.
These cylinders are also available for our EPA and CEMS standards providing long term environmental monitoring solutions for all NO2
applications.
As has been demonstrated, there are multiple options for calibrating and bump testing NO2 can meet customers specific requirements. For further information on our calibration gas solutions for NO2
application, contact CAC GAS & Instrumentation. More information online:
