Air Emissions from vessels can be defined as gases discharged into the air from the internal main combustion engine, generators, boilers, etc. for example, carbon monoxide, nitrogen oxide, nitrogen dioxide, sulfur dioxide, etc. On specific emissions produced by a vessel there are charges (or emission fees).
The Air Emissions module is designed to enable users to calculate and identify not only the total emission quantity a vessel or fleet produces, but also the respective amount and total cost of each generated emission type. Calculations are possible for a broad range of different emissions, for example based on various fuel consumption data, the exact amount of for example NOx, SOX, CO2, etc., produced by a fleet or vessel can be identified.
In addition, it is possible to produce automated reports, for example, Yearly Fleet Emission, Detailed Voyage Emission, Monthly/Quarterly Reports (Prorated Emissions), Official Emission Tax Reports, etc. Once issued, the reports can be sent directly to a business partner or appropriate government body. The module can also be utilised to monitor a fleet’s environmental footprint to enable a reduction of greenhouse gas emissions.
The Air Emissions module is represented by the Air Emissions- and Air Emission Fees tabs in the Vessel Administration module. In the Air Emissions tab the different emission types can be entered and in the Air Emission Fees tab various emission fees can be entered. Emission fees are defined and linked to an emission type in the Emission Fees module in Master Data. The Emission Fee Types module holds information about the five emission types currently supported (and maintained) by Dataloy.
To calculate for example a vessel’s emissions, the fuel type/s, the emission factor of each specified emission type of each fuel type (ex. FO High Sulphur) for each vessel MUST be entered in the Air Emissions tab and the emission fees in the Air Emission Fees tab. An emission factor can be defined a measure of the average amount of a fuel emission, expressed in pounds or kilograms of particulate per metric tonne of the fuel.
