Reducing Impact from Shipping on the Environment

The project will encompass three activities Ship emission indicator Today's serious concern is on global climate and local air pollution in densely populated areas. This proposal will concentrate on ship emissions to the air. Special focus is on following items: - Decision on emission components to be included, based on study regarding prioritised components by IMO, UN IPCC and EU. - Alternative methodology regarding component specific indicators will be evaluated and discussed, based a.o. on Session pape rs from IMO MEPC and similar by EU Com. - Relevant weighting factors will be evaluated and decided in communication with Norwegian Pollution Control Authority - For the selected test ships, baseline emission indicator will be suggested. - Ship emission index will be suggested and tested, defined as accumulated registered emission indicator compared to proposed baseline figures. Performance indicators for 4-stroke engines As far as convenient the project will make use of the models and experience from the TOCC activity for 2-stroke main engines. Special focus is on following items: - Means to make the models more robust regarding erroneous cylinder pressure indication will be analysed. - Means to make models robust also regarding instable test conditi ons to be investigated and tested. The activity covers development of guidelines to obtain acceptable test conditions. - Based on the above development the models and guidelines will be implemented and tested on a limited number of selected ships. Metho ds and infrastructure This activity enables the use of the environmental indicator and the 4-stroke engines in the infrastructure that provide decision support to improve performance. Methods to validate measurement data and to test reliability in regist rations will be extended. Guidelines that repair for missing knowledge / competence and that are essential to provide quality input to models will be developed.
