Emissions Monitoring

Being an end-to-end digital transformation platform, METIS provides a  CO2 monitoring system that helps shipping companies to monitor and manage the emissions in order to ensure regulatory compliance and reduce their environmental footprint. The main benefits for a shipping company that has deployed a system that monitors CO2  emissions are in brief the following:

  • Verifies if the vessel’s operation complies to the environmental guidelines and regulations
  • Estimates the variation of the emissions over time. This information can indicate a vessel faulting/fouling
  • Helps to plan voyages and optimize vessel operation in an environmentally friendly way
  • Provides significant help to improve the environmental efficiency of the vessel, among other services,

Average Efficiency Ratio (AER)

METIS - AER - Fleet

Average / Annual Efficiency Ratio (AER) is expected to be adopted by IMO as the Carbon Intensity Indicator (CII) in order to monitor the operational efficiency of the vessels in regard to the targets set to reduce the GHG emissions (CO2) generated by the shipping industry.

Additionally, AER is selected by the financial institutions (that are part of the Poseidon Principles) in order to monitor the operational efficiency of the vessels that they finance, linking their performance to the loaning terms.

Based on a reliable Data Acquisition system METIS automatically collects all the necessary data, makes the calculations and provides information regarding the actual AER in comparison to the target values.

Probably the most significant aspect of the functionality has to do with the prediction of the year on which each vessel is expected to be above the target values. Shipping companies thus are able to meticulously monitor these indexes in a dynamic way having all the information available in order to take all necessary actions proactively.

AER is vessel type, size and year dependent

METIS Machine learning algorithms have been used to ensure the completeness and the accuracy of the information. The results can be used as an indication of the vessel’s performance regarding the environmental emissions and investment decisions.

Grouping of vessels is available through the METIS platform to make the monitoring more convenient. There are various grouping options some of which are according to:

  • Fleets
  • Vessel types
  • Sister vessels

Monitoring

METIS is able to provide valuable information regarding the CO2  emissions of a vessel by collecting and processing information such as:
  • The cargo weight
  • The vessel specifications (MCR, capacity, etc.)
  • The traveled distance at sea
  • The bunkering fuel analysis and delivery notes
  • The fuel oil consumption per fuel type
  • The Main Engine’s and Diesel Generators’ produced power
  • The vessel’s speed
The following quantities can be calculated:
  • The CO2 emissions
  • The SOx emissions
  • The NOx emissions
  • Information about the correlation between the emissions and the engine power
  • Information about the correlation between the emissions and the vessel’s speed
  • The Energy Efficiency Design Index (EEDI)
  • The Energy Efficiency Operational Indicator (EEOI)
  • The correlation between the emissions and the engine power
  • The correlation between the emissions and the vessel speed
  • ECA-related information (time inside an ECA, Fuel Consumption at ECA, etc.)
