Worldwide shipping is a concern for environmentalists. As it is dependent on fossil fuels, it accounts for nearly 3 % of greenhouse gas emissions. Therefore, decarbonisation of the sector is a priority. In this context, the EU-funded HEMOS project will work on decarbonising the EU’s fleet by improving the heat energy system of ships. Specifically, it will optimise heat flow topology with a dynamic calculation model, in addition to including latest advancements in heat-energised technologies. The project will validate the calculation model with a real-life onboard prototype. The aim is to create an innovative approach towards the design of new heat energy systems on ships. The main target is to reach a 14 % efficiency increase to reduce emissions.
The project aims to decarbonize EU’s fleet by improving ship’s heat energy system through optimization of heat flow topology with dynamic calculation model, as well as including latest advancements in heat energized technologies. In this project all major consumers, heat producers and waste heat sources are considered. Furthermore, the calculation model is planned to be validated by real-life on-board prototype, to go further from theoretical calculations and experience. Thus creating a new innovative approach towards design method of heat energy system on the ships. The main target is to reach 14% efficiency increase by the calculation and scale it down to prototype to validate.
The project is divided into three phases. First phase is concentrated on researech and development of the calculation tool based on the collected on-board data from the case study ship, with an outcome of new heat energy system topology with best efficiency based on limitations given by the ship owner. The second phase continues with development of process and system engineering for the optimized system arrangement, with an outcome of initial automation and interface principles. Third phase is a practical installation of prototype on board of the case study ship and validation of the calculation model vs real installation.
The validation will impact shipowners perception on the possibilities to upgrade their ships. Additionally will provide valuable experience to participating parties to strengthen EU companies position on the market with high-end technology and heat energy efficiency optimization on ships. The efficiency increase will help to reduce ship emissions in CO2; NOx; SOx and particulate matter which is getting critical from EU enviromnental strategies.
