The merchant marine fleet is under inspection by several parties to ensure maritime regulation compliance. International Maritime Organization mainly regulates the industry, and the most effective defender is indeed Port StateControl run by the regional memorandum of understandings. This article aims to analyze all detention remarks of Paris Memoranda of Understanding (MOU) from 2013 to 2019 for EU15 countries (except Luxemburg and Austria) to guide marine industry on detainable Port State Control remarks and country risk profile. The data of the detained vessels taken from the public website of Paris MOU and each report considered as a professional judgment that causes detention. Analytical Hierarchy Process Approach has been utilized to indicate the ranking of basic maritime regulations from the perspective of the Port State Control, and Geographic Information System (GIS) helps us to demonstrate the regional dispersion amongst EU15. Through an approach based on Analytical Hierarchy Process and demonstrating the results on GIS has been shown that almost all the country’s top priorities for regulation are Safety of Life at Sea (SOLAS) and Fire Safety Systems (FSS). Moreover, a comparative demonstration of the detention percentage of each regulation to AHP results demonstrates a better understanding of EU15 countries' detention profile. The results of the study can assist Port State Officers, ship crew, ship owners, and managers in presenting the facts of their inspection and able to improve themselves. The spatial analysis is also expected to guide ship owners and managers to focus their vessel’s deficiencies on preventing sub-standardization. Policymakers also utilize these reports to evaluate their inspection practices.

港口国控制拘留评论等级：专业判断和空间概述

商船队正在接受多方检查，以确保符合海事法规。国际海事组织主要监管该行业，而最有效的捍卫者的确是由该地区谅解备忘录管理的Port StateControl。本文旨在分析2013年至2019年间针对欧盟15国（卢森堡和奥地利除外）的巴黎谅解备忘录（MOU）的所有扣留说明，以指导海洋工业关于可扣留的港口国管制说明和国家风险状况。从巴黎谅解备忘录的公共网站上获取的被拘留船只的数据以及每份报告均被视为导致拘留的专业判断。从港口国控制的角度，采用了层次分析法来表示基本海事法规的排名，地理信息系统（GIS）帮助我们证明了欧盟15国之间的地区差异。通过基于层次分析法的方法并在GIS上论证的结果表明，几乎所有国家/地区的首要监管法规都是海上人命安全（SOLAS）和消防安全系统（FSS）。此外，通过比较证明每条法规对AHP结果的扣留百分比表明对欧盟15国的扣押情况有了更好的了解。研究结果可以帮助港口国官员，船员，船东和管理人员陈述其检查的事实并能够改善自己。空间分析还有望指导船东和管理者将其船舶缺陷集中在防止不合标准的问题上。
