Evaluating the performance of the vessel train concept

Abstract

Abstract Objective To improve safety and address current employment challenges in the waterborne transport sector, the VT concept is developed. The VT is a vessel platooning concept that is semi-autonomous. The VT is composed by one Leader Vessel (LV) and Follower Vessels (FVs) that will be connected with each other with sensors. The research examines from a business-economic and societal perspective, whether it is interesting to invest in and use the VT, instead of sailing with a conventional vessel. Methods The business-economic performance of the VT is tested from theperspective of the vessel owner (VO) for the inland navigation trajectory Antwerp – Rotterdam – Duisburg, using a relevant transport model. With this research, the results allow comparison of the total costs of the reference scenario with alternative VT scenarios and thus allow to see which of the scenarios are interesting for the VOs to invest in and use the VT. From a societal perspective, the expected modal shift from road (and possibly rail) to inland waterways and the external cost savingsfor the society are calculated. Results The results show that for some scenarios the expected benefits of the society are high, thanks to the modal shift from road (and rail) to inland waterway transport (IWT) mode and to the reduced external costs. However, for the scenarios with negative business-economic cost savings, negative welfare gains are found due to the likelihood of reverse modal shift from IWT to road (and rail), because the VT is found more expensive than the conventional sailing. Implications for research/policy If all the actors of the VT project have benefits, being theVO, the VT organizer (VTO) and the cargo owner (CO), the implementation of the VT concept will be decided. The implementation of the concept can still be decided, if the loss of one of the actors is compensated by the other(s) actor(s). Thus, subsidies by the government are not needed. However, what is needed is the change of the current legislation that would allow the sailing of the VT with reduced crew on board in inland waterways.
