Decision support tools for owners of inland and coastal vessels
The purpose of this tool is to explore options to reduce climate change and air pollutant emissions of vessels. The tool takes into account the type of vessel the current type of propulsion and operational characteristics such as the energy demand and the autonomy. The user of the tool can select the required emission reduction. Next, the model will then select technologies and energy types which achieve the required emission reduction. The model can also take into account operational elements such as the loss of productivity, resulting from loss of payload and more time required for bunkering or recharging when using alternative energy solutions (e.g. batteries). When using economic data of the vessel (e.g. turnover, profits) the economic impact of loss of payload or additional bunkering time is expressed in euros. Possible subsidies on the capital investments can also be entered in the model, which helps the economic feasibility. The model calculates the estimated costs of using these technologies and energy types within a bandwidth (min, max) and compares the results with the costs of running the current vessel. In the results, the model presents top 3 of options which have the best economic performance to reach the emission reduction levels. Furthermore, detailed results are made available by the model on both the economic data and the emission data. Tables and graphs are presented in the results page.
The results can be downloaded as well to Word, PDF or CSV files.
IWT Tool Coastal Shipping Tool
The tool contains the following technologies from the SYNERGETICS catalogue:
- New diesel engines with after treatment systems (SCR and DPF)
- Usage of renewable diesel (HVO100) in diesel engines
- Methane combustion engine, using Liquid Natural Gas or Liquid Bio Methane (Bio-LNG)
- Methanol combustion engine, both single fuel and dual fuel, using grey or green methanol
- Hydrogen combustion engine, both single fuel and dual fuel, using grey or green hydrogen, either with bunkering from shore of with swapping the tanktainers
- Full electric propulsion using Hydrogen Fuel Cells and fixed battery, using grey or green hydrogen, either with bunkering from shore of with swapping the tanktainers
- Full battery electric propulsion using fixed batteries on board with fast charging from shore
- Full battery electric propulsion using swappable batteries in a pay-per-use system
The model gives therefore a first idea to the vessel owner about the technologies which would suit the vessel and the operational profile. As a next step the vessel owner should get in contact with a shipyard or technology suppliers to ask for more specific quotes and cost estimates.
