Optimal Berth Allocation in Ports with The Deployment of Shore to Ship Power System

Port emissions can be considerably reduced with the execution of maritime electrification. This paper studies the optimal berth allocation problem (BAP) combined with an onshore power supply known as cold ironing in response to the growing interest in maritime electrification. The problem is formulated as a mixed integer linear programming (MILP) optimization problem to reduce the total processing time, including the ship's handling and waiting time at the port. The findings from simulation analyses indicate that scheduling ships staying at the berth terminal with a cold ironing service results in a longer waiting time compared to the case without a cold ironing system. However, optimal berth allocation considering shoreside power supply greatly reduces the NOx, SO2, CO2, and PM pollution by 97.7%, 96.7%, 38.4%, and 92.1% respectively.
