Maritime electrification is reshaping the interaction between ships and ports from pure logistics to an integrated energy-logistics coupling. However, the proliferation of electrified ships (ESs) connected to ports, if not managed effectively, can result in port congestion and inefficient resource utilization. Unlike land-based electric cars, which only require energy services when parked at charging stations, ESs docking at ports necessitate the port call service including both energy service and logistics service for cargo handling. To address these issues, this paper proposes a generalized Nash game framework to coordinate energy and logistics service utilization strategy for ESs. Each shipowner aims to minimize their own economic cost, while satisfying their specific energy and logistics demands and adhering to global coupling constraints. Notably, ESs can also participate in arbitrage by selling electricity back to the port during port stay, which can be referred to as ship to port behavior (S2P). Moreover, the existence and uniqueness of the generalized Nash equilibrium are proven. In addition, due to selfishness and privacy concerns, shipowners are reluctant to disclose private constraints and personal objectives to others, so a decentralized algorithm is developed to seek the generalized Nash equilibrium. Simulation results demonstrate the effectiveness and efficiency of the proposed method.
