Overview

The GAA330-M is a CEM system designed to measure the gas pollutants SO2, CO2, and NOX, as specified in MARPOL Annex VI. The GAA330-M operates with both high- and lowsulfur fuels, no matter if you are operating outside or inside an ECA. ABB has the right gas analyzer portfolio to allow vessels to stay compliant with current and upcoming regulations. The GAA330-M uses an Infrared photometer for reporting the SO2/CO2 ratio as specified by MARPOL requirements. NOX is monitored with an ultraviolet photometer (UV) which is the most practical approach. ABB photometers are manufactured and designed for best performance under harshest conditions with an installed base of more than 100.000 units in global industries.

Maritime industry – background The International Maritime Organization (IMO), has introduced regulations to prevent air pollution from vessels both globally and within designated sea areas, known as Emission Control Areas (ECAs). The ECAs are geographical locations and are defined as: North Baltic Seas, all North American Coasts & Caribbean coastal areas. Other areas are under evaluation by IMO. These regulations require control on SO2 , CO2 and NOX emissions. The Maritime Industry is facing challenges to either adopt new technologies such as exhaust gas cleaning systems (EGCS) or use of low sulfur residual or distillate marine fuels to comply with the ECA requirement. Engine manufacturers and ship owner are challenged to reduce NOX emissions. The new set limits in the ECAs can be achieved only with clean fuels or by making use of DeNOX abatement systems. Ship yards, ship owners and marine ECGS manufacturers are looking to equip vessels with continuous gas analyzers for Continuous Emission Monitoring (CEM) to measure all the regulated pollutants (SO2, CO2, NOX) and to optimize fuel consumption (CO, O2) on board at the same time.
