Simulation Model for Economic Analysis of Shore Power Technique

Abstract

Maritime vessels utilizing shore power while docked offer significant potential for substantial reduction of exhaust emissions, consequently mitigating atmospheric pollution within port environs. However, the substantial initial investment costs associated with constructing shore power infrastructure and retrofitting vessels with shore power access equipment pose a substantial challenge, as the short-term economic returns are not readily apparent. This unfavorable aspect significantly impedes the widespread adoption of shore power technology. Furthermore, dynamic factors such as government subsidy policies, environmental mandates for maritime vessels, electricity pricing, fuel costs, and port queuing strategies exert direct influence over the economic returns of shore power systems, thereby introducing significant complexities into the comprehensive evaluation of their economic viability.In response to these challenges, this paper presents a simulation model designed to replicate the behaviors of vessels, shore power facilities, and dynamic factors. This model offers a detailed estimation of the economic benefits of shore power systems throughout their entire lifecycle under various operational strategies. The simulation model is implemented using the Anylogic tool. The results indicate that the simulation outcomes over the past three years closely align with actual data, thus affirming the reliability of the model. The simulation model serves as a valuable decision-making tool for vessel operators, shore power stakeholders, and governmental authorities. It is conducive to the promotion of shore power adoption and enables the projection of the economic benefits of shore power systems over a defined time horizon.
