The goal of the research in a frame of project DEcision Support System for green and safE ship RouTing – DESSERT is the development of an effective Decision Support System (DSS) is planned for ship captains as well as machine commanders, which would contribute to "greener" and safer navigation of ships. The ultimate impact of such a DSS would be to make human error as small as possible, or to provide responsible persons on board the most credible data and guidance during navigation to reduce environmental pollution and make people and cargo safer.
Research related to the development of DSS will take place in two main directions: energy-efficient navigation along with reduction of greenhouse gas emissions; and increase sailing safety by collision avoidance as well as from timely reactions in the event of flooding. Within the scope of the survey, the design, implementation and analysis of questionnaires (surveys) designed for captains and engineers on ships are planned. The intention is to get the most credible data on the crew response to the individual dynamic effects caused by the worsening of weather conditions. Survey analysis is designed to get feedback on the criteria and limit values of the criteria that are relevant to deliberate speed or course change due to excessive ship motions on waves, and to develop a "virtual captain" model to be used when simulating and planning the navigation route. Significant scientific contribution to research is related to ship propulsion plants. It is planned to develop new or a combination of existing methods that will significantly affect the reduction of harmful emissions both from marine diesel engines and from marine steam turbine plants. If possible, measurements with the acquired measuring equipment will also be carried out on ships using gas-turbine propulsion, so that significant scientific contributions can be expected.
The research will provide a framework to assess in an objective and reliable manner the safety state of the ship in a generic operative condition. The framework can be used inside DSS to monitor safety and reduce risk during navigation, as well as in emergencies. By means of simulations and/or predictions, it can allow a simple comparison of different loading conditions, ship routes and weather scenarios being the base for the minimization of risk in intact condition as well as for the evaluation of countermeasures during an emergency. By including all the aspects connected to ship safety in a unique tool, it could reduce human errors occurring when a great amount of data has to be processed at the same time (a critical operation especially during an emergency).
The objective is to develop decision support system on board taking into accounts the environmental issue, creating a so-called safe and eco-efficient or “green” ship. The project team consists of the scientists who are experts in the naval architecture, mechanical engineering, marine engineering field and computational sciences, which allow solving this problem multidisciplinary.
