Stability of a Ro-Ro Ship: An Assessment of the Impact of Electric Vehicle Transportation

Abstract

In terms of service lives, ships have the ability to remain operational for extended periods of time, potentially exceeding several decades. Changes in machinery and equipment are dependent on technological improvements. The above change is most noticeable in the components that make up ship systems. Nonetheless, the movement of ships on the water involves research into a variety of topics, including static-dynamic equilibrium and the demands of speed and power. The study focuses on the growing fascination with electric automobiles, which can be ascribed to technology improvements, environmental policies, and the concept's widespread acceptance. As a result, there has been a boom in interest in purchasing electric vehicles and using them for transportation. When conventional internal combustion engine automobiles are considered during the design process of marine vessels that transport land vehicles, it is expected that electric vehicles (EVs) will be primarily transported by Roll-on/Roll-off (Ro-Ro) ships in the foreseeable future. However, weight discrepancies exist between electric vehicles and other models in the same category. The significant weight attributed to batteries emphasizes the significant possibility for advancement in modern battery technology. The purpose of this research is to look into the variations in the stability of a Ro-Ro vessel when transporting an equal number and weight of EVs and conventional automobiles.
