Abstract
Sustainable mobility is one of the most challenging issues for passenger transport inside environmental protected areas and ecologically fragile environments. To reduce the pollutant emissions, the adoption of electric or hybrid-electric solutions for crafts propulsion is a suitable option for green navigation. However, the operation in restricted basin leads also to specific critical issues for the vessel sailing, as dealing with shallow or restricted waters and transit under low air-gap bridges. The combination of these constraints with the adoption of a hybrid-electric propulsion system increases the design difficulties also for a small craft, requiring the use of advanced simulation models to assess the vessel performances. This work presents a simulation model for a small passenger craft that will operate in the Grado Lagoon. The model combines the hydrodynamic issues of manoeuvring and propulsion in restricted water with the simulation of the electric loads and capacity of the energy storage system installed onboard. The simulations performed with the developed simulation system are in accordance with data measured during trials on a prototype of the vessel. The developed model is a powerful tool for designers in order to rapidly assess the green capabilities of new projects since the early design stages.
Highlights
With the increase in public awareness on environmental preservation, air pollutants from ship exhaust emissions are addressed with more and more attention [1, 2]
Many studies presented that nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM) emitted from international shipping account for 13%, 12% [3], and 1% [4] of total global NOx, SOx, and PM emissions, respectively
Ship emissions in ports may have a significant impact on local air quality, population exposure, and, human health in harbour cities
Summary
With the increase in public awareness on environmental preservation, air pollutants from ship exhaust emissions are addressed with more and more attention [1, 2]. As a result of the importance of the climate change challenge, the International Maritime Organization (IMO) has strongly developed and implemented new measures to address pollutant emissions from ships. E determination of the propulsive loads has an impact on the selection of the energy storage system to be installed onboard for performing ZEM navigation on a specific route. Rough this paper, from a campaign of surveys performed during the trials of a real inland water passenger craft prototype, a route simulation model for inland and coastal navigation [15] has been enhanced to include the possibility to evaluate the state of charge of the battery packs installed onboard, considering the real power demand during a route. Anks to the validation with trials measurements, the developed simulation model can be considered a reliable tool for green craft designers to be used in the early design stages of new projects in order to assess the ZEM performances of the vessel
