ABSTRACT

Abstract:

Electrified vehicles (EVs), including hybrid electric vehicles (HEVs) and pure electric vehicles (PEVs), can provide substantial improvements in energy efficiency, emission reduction, and lifecycle cost over conventional vehicles solely powered by internal combustion engines (ICE). Progress on electrification of marine vessels has been made, but the pace has been impacted by factors such as different operational load profile of vessels, relatively small production levels and longer or varied lifetimes. In this Seminar, hybrid electric and pure electric propulsion system designs for fishing boats and passenger ferries will be presented based on in-field acquired operational data. A new integrated marine propulsion system modelling and simulation method and a dedicated mobile data acquisition system will be introduced to analyse the energy efficiency, emission reductions, and lifecycle costs of a new or retrofitted fishing boat and passenger ferry with hybrid electric and pure electric powertrains. Following the automotive industry model based design (MBD) approach, modelling and simulation of electrified vessels using the acquired operation profile have been carried out using backward and forward-facing methods. Series hybrid electric and pure electric powertrain system designs with powertrain component models and rule-based system control, including properly sized electric ESS with a supercapacitor (SC) or battery, have been studied. The total CO2 equivalent (CO2e) or greenhouse gas (GHG) emissions and lifecycle costs of various new, electrified vessel propulsion system designs have been evaluated. Clean propulsion system solutions for fishing boats and passenger ferries with detailed powertrain system and control system designs which provide foundation for further research and development.​
