CEMcaptain GAA610-M

Emission monitoring on your wavelength

Continuously providing real-time data it integrates analyzer modules and sample handling components in a standalone cabinet.

The CEMcaptain GAA610-M robust system design is dedicated for marine environment and is suitable for high ambient temperatures up to 55°C and high vibration resistance. It is protected against soot ingress with innovative filter solution and back-purging option for easy integration and alignment with scrubber operation procedure.

The CEMcaptain GAA610-M analyzer solutions are designed with busy maritime engineers and a regularly changing crew in mind and are installed on board hundreds of ships worldwide





The basic version is equipped with ABB’s renowned Uras26 non-dispersive IR gas analyzer and measures simultaneously and continuously SO2, CO2

Two separate gas paths allows continuous CO2/SO2 measurement of separate streams with only one analyzer and up to 4 components per analyzer module

Emission monitoring for clean air on oceans brings maritime air pollution control closely in line with shore-based power plants, cement works and oil refineries, where continuous emissions monitoring systems (CEMS) have been used for decades. As from the January 1, 2020, the low sulphur emission limits in the IMO regulations became effective worldwide. 

The International Maritime Organization (IMO) set out the MARPOL Annex VI regulations aiming to control of the main air pollutants emitted by vessels. These regulations focus on the control and reduction of sulphur oxides (SOx) emissions: Regulation 14 for control and monitoring of SOx emitted by the combustion of heavy fuel oil (HFO) engines SOX control guidelines are specified in the MEPC.259 (68). 
They apply in all Emission Control Areas (ECAs) starting January 1st 2015 on and have started in 2020 globally.

In order to control the efficiency of exhaust gas cleaning systems (EGCS) and following MEPC.259 (68), measurement of SOx/CO₂ ratio is required.
The NOx Technical Code (NTC) 2008 specifies the measurement performance of a CEMS on board of a vessel. Ship yards, ship owners and marine ECGS manufacturers need to equip vessels with exhaust gas cleaning systems (EGCS) for continuous analyzer systems to measure: sulphur oxides (SOx), carbon dioxide (CO₂)
