Port State Control (PSC) is a vital element of sustainable maritime transportation. Inspections of PSC regimes have been ensuring the continuity of the global supply chain as they enforce shipping to implement the maritime regulations to be safe, secure, and environmentally friendly. Since the beginning of the COVID-19 Pandemic, the number of onboard ship inspections has decreased inherently for protecting PSC officersand seafarers, while PSC regimes have developed a policy to focus on a high-risk ship based on historical inspection records. In this context, planning for a “new normal” in maritime transportation, it is essential to realize the change in ship inspection numbers and the trend of deficiency - detention factors for the maritime sector to provide current standards. This study aims to present the difference in ship inspection trends between 2017-2020 by focusing on COVID-19 pandemic outbreak data. Comparative analysis with Paris MOU ship inspection & detention figures and entropy-based Grey Relevance Analysis has been used as a methodology to reveal the change in inspection trends after COVID-19. After the pandemic outbreak caused by COVID-19, the number of ship inspections under Paris MOU fell dramatically, however, inspection and detention rate remained the same, also entropy-based Grey Relevance Analysis indicates that detention remarks have also changed compared to last year deficiencies. Detention caused by nautical publication and cleanliness in the engine room has an increasing trend on detentions. Inspection statistics indicate consistent figures even during the pandemic outbreak, which indicates the current sample group for Paris MOU inspection is healthy. At the same time, entropy-based Grey Relevance Analysis presents a broader insight that the inspection trend on detention deficiencies has varied. Familiarization with the changing trends in inspections will cause fewer detentions of the ships.

大流行病爆发下欧盟的港口国控制


港口国控制（PSC）是可持续海上运输的重要组成部分。对 PSC 制度的检查一直在确保全球供应链的连续性，因为它们强制航运实施安全、可靠和环保的海事法规。自 COVID-19 大流行开始以来，为了保护 PSC 官员和海员，船上检查的数量自然减少，而 PSC 制度则根据历史检查记录制定了一项政策，重点关注高风险船舶。在此背景下，谋划海运“新常态”，有必要认识到船舶检验数量的变化和滞留因素的趋势，为海事部门提供现行标准。本研究旨在通过重点关注 COVID-19 大流行爆发数据来呈现 2017 年至 2020 年船舶检查趋势的差异。与巴黎谅解备忘录船舶检查和滞留数据的比较分析以及基于熵的灰色相关性分析已被用作揭示 COVID-19 后检查趋势变化的方法。 COVID-19疫情爆发后，《巴黎谅解备忘录》下的船舶检查数量大幅下降，但检查和扣留率保持不变，而且基于熵的灰色相关性分析表明，扣​​留言论与去年相比也发生了变化。 。因航海出版物和机舱清洁造成的滞留有增加的趋势。检查统计显示，即使在疫情期间，数据也保持一致，这表明目前巴黎谅解备忘录检查的样本组是健康的。 同时，基于熵的灰色相关性分析提供了更广泛的见解，即拘留缺陷的检查趋势有所不同。熟悉检查趋势的变化将减少船舶的滞留。
