EmissionSEA – Extrapolation of emissions from ships
Table of Contents
Global climate goals, stricter emission regulations, and noticeable cost pressure are leading to ever greater incentives to reduce ship emissions and increase the energy efficiency of shipping. In particular, the EU reporting regulation on CO2 emissions from, to, and within the European Union, which has been in force since 01.01.2018, has led to an increase in the energy efficiency of shipping. The specification of CO2 emissions is mandatory. However, there are currently no sufficiently suitable methods to validate reported emissions, since the ships are operating worldwide and the routes are recalculated due to adverse weather conditions, projections such as those for road traffic cannot be implemented.
The aim is to develop a methodology for the quantitative determination of CO2 emissions from shipping. With the help of data from the Automatic Identification System (AIS), movement information is set in relation to ship size, speed, and meteorological and oceanographic environmental conditions. More than 500,000,000 daily AIS data records from hundreds of own and thousands of cooperative AIS base stations as well as detailed ship data including information on the main propulsion plant are available to JCS and form the data basis for the project. Data on fuel consumption and emissions are not publicly available and represent the gap to be closed.
Position Data preparation and quality improvements
Reference Vessel Generation
For each requiring AIS equipment vessel, the calculation of the emitted carbon dioxide should be functional. JCS has very detailed information for practically all ships. Especially for newbuildings, however, not all required data may be available yet. Therefore, more than 450 ship models have been generated which serve as a basis for calculation in case of missing detailed data. This was developed by the CML.
The resistance model
For reliable emission estimation, the development of a complex and innovative model to represent the resistance of the ship’s hull is necessary. This package includes the development of a hull drag model based on AIS, weather, environmental and static ship data. This work package was mainly developed by the CML.
The emission model
User surveys were used to work out what their expectations are for the validation of emissions. This is reflected in the frontend. The JAKOTA Design Group is responsible for this work package. It is now possible for the user to select any ship and have the Co2 emissions calculated. These can then be compared with the MRV data. This makes it possible for ship owners to verify their data (check for human errors) before sending it. Maritime authorities now also get the ability to investigate reported emission data for anomalies. This Work
