Abstract

Shore power (SP) is widely recognized as an efficient strategy for reducing greenhouse gas emissions from vessels while docked at ports. Nevertheless, many SP systems are used irregularly, which results in inefficient emission reduction. This study evaluates SP implementation and utilization in China in 2022 using data from 18,724 ships and 6,551 berths. The primary objective is to identify discrepancies in SP construction and usage, especially with regard to ships and berths that differ in terms of tonnage, types, regions, and other characteristics. Using an apriori algorithm, the study looks into the relationship between SP usage and these unique features. Tailored approaches are proposed to improve SP usage addressing specific barriers that result in the low SP utilization rate among these features. The study also measures the increase in the number of ships using SP and the subsequent decrease in carbon emissions as a consequence of these tactical strategies.

调查岸电利用率与船舶和泊位特征之间的关系

岸电（SP）被广泛认为是减少船舶停靠港口时温室气体排放的有效策略。然而，许多岸电系统使用不规范，导致减排效率低下。本研究利用 18724 艘船舶和 6551 个泊位的数据，评估了 2022 年中国 SP 的实施和使用情况。研究的主要目的是找出SP建造和使用中的差异，尤其是船舶和泊位在吨位、类型、地区和其他特征方面的差异。该研究使用一种先验算法，研究 SP 使用与这些独特特征之间的关系。针对这些特点中导致 SP 使用率低的具体障碍，提出了提高 SP 使用率的定制方法。该研究还衡量了使用 SP 的船舶数量的增加情况，以及这些战术策略带来的碳排放量的减少情况。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
