Real time ship exhaust gas monitoring for compliance to SOx and NOx regulation and CO2 footprint

IMO MARPOL Annex VI regulation has been set for global application to reduce the negative consequences of ship gas emissions SOx, NOx, and CO2. To enforce the regulation, real time gas emission monitoring system is in need. The system in this paper consists of a microcontroller, gas analyzers, sensors and Xbee radio module. The data acquired from the sensors and gas analyzer is transmitted using a microcontroller over the Xbee module to the receiver Xbee module on the main microcontroller for real-time compliance check. Real time monitoring system expedites the checks by officials in enforcing the regulation. Ultimately, this application enables engine manufacturers, ship-owners and Administrations to ensure in real time that all applicable marine diesel engines are in compliance with the limiting values determined by IMO MARPOL Annex VI. This paper offers the solution of the lack of technology mentioned above. Important parameters for compliance are measured by sensors that give electrical signal output of various types. After that, the data value from the sensors is collected by the microcontroller (data acquisition system). The microcontroller processes the data calculation and output the value useful for end-user such as SOx, NOx and CO2 emission. This end-user data is stored in the local memory of the microcontroller. Thereafter, the end-user data is transmitted through the Xbee to the receiver Xbee on the main microcontroller. This end-user data obtained by the main microcontroller is then stored and used
