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 Iridium radio module. The data acquired from the sensors and gas analyzer is transmitted using a microcontroller over the Iridium satellite to the ground station for real-time compliance check. Real time monitoring system expedites the checks by the ground station 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.
