Effect of Electric Vehicle Transportation and Carbon Capture System on Concept Ro-Ro ship Stability and EEDI

Abstract

In terms of their service life, ships may operate for decades. Hence, it depicts the rapid development of machinery and equipment due to the substantial advancement of technology. Indeed, the ship’s systems must be updated to accommodate these new instruments. However, the importance of investigating the static-dynamic equilibrium and speed-power demand is a matter of concern as the ships are in motion on the water. There are currently limitations on carbon emissions from ships. To comply with these regulations, either the use of fuels that produce fewer carbon emissions or the use of after-treatment techniques to prevent the release of carbon into the atmosphere are employed. The difficulty of integrating any new system into an existing ship increases the scope of the renovation. This study compares the stability, speed-power, and EEDI values of today’s most popular electric vehicles while being transported on a concept Ro-Ro ship with and without a Carbon Capture System (CCS) ship. In the scenario where the ship transports both conventional and electric vehicles, the number of vehicles transported remains constant, but the effects of electric vehicles being heavier are illustrated. A ship with CCS and loaded with electric vehicles has 23.5% less maximum GZ than a regular ship with the traditional vehicles loaded condition by approximately 6% less at an angle of heeling. Also, the EEDI level is approximately one-twentieth of the conventional model, which is an advantage of CCS.

Application of an offline grey box method for predicting the manoeuvring performance

“…The parameter estimation process started with initial numerical values given in Tables A. 1 and A.2 in Appendix 1 for car carrier and KVLCC2 respectively and ended with fine-tuning of the parameters given in Tables A.2 and A.3 for KVLCC2 and car carrier respectively.…”

“…The growing global adoption of electric vehicles is aimed at reducing the carbon footprint of passenger vehicles, thereby increasing the importance of car carriers in transporting these vehicles to ports [1]. The use of new technologies such as digital twins on surface ships has the potential to help stop the rising global journal homepage: www.brodogradnja.fsb.hr 2 warming threat by reducing CO2 emissions and to increase maritime safety by preventing possible ship collisions in marine environments [2].…”
