After building a ship in a shipyard, there are so many repeated inspection of welding seam defects and painting status before delivering to the ship's owner. An inspection on the bottom part of a ship in commercial service should be done in every two years for the purpose of safety and for the prevention of ship speed deterioration. conventional welding seam inspection systems are rely on the visual inspection by human or the ultrasonic inspection for the selective part of a ship. This paper suggests a remote controlled inspection system for the examination of large ships or steel structures. The proposed system moves in contact with the ship under inspection and have a CCD camera to provide visual-guidance information to a remotely located human worker. Additionally this system utilizes a weld line tracking algorithm for an optimal position control. We verified the effectiveness of the inspection system by experimental data.

According to the United Nations Convention on the Law of the Sea (Article 94), the flag state must fulfill its overall role to ensure maritime safety and operate the ship inspection system as a related measure. The Korean government (Ministry of Ocean and Fisheries) has implemented policies for reducing marine accidents to promote maritime safety; however, the target goal has not been achieved. The ship inspection system is a measure to prevent marine accidents, and for the effective operation of the system, a sufficient understanding of the origin of the ship inspection system is required. In this study, the trend of the international ship inspection system was identified by analyzing ship inspection system origins and the history of the system's paradigm shift. The recent international ship inspection system paradigm confirms international standardization and the active safety management of ship companies are becoming increasingly prominent. Based on this, the introduction of the 'PDCA cycle-based self-inspection system' is presented to the current domestic ship inspection system. This is a new type of inspection system that establishes the roles of interested parties based on the basic philosophy of the ISO 9000 series to improve the ef ectiveness of maritime safety. Additionally, the necessity for a non-face-to-face ship inspection system has emerged because of the COVID-19 pandemic. Hence, the transition to a 'mobile application-based ship inspection system' is proposed to accommodate the rapid development of information communications technology.

On this research, recognizing that ship inspection and audit services are closely related in Improving ship safety, the importance of active quality managements of ship inspection and audit services have been notified. For this research, based on previous research results, Quality managements of ship inspection and audit services were divided into the following aspects; the source of quality managements, execution of quality managements and outcome of quality managements. The results of this study is as follows. Overall, it is clearly shown that the elements of quality managements execution such as management responsibilities, resource management., product realization, measurement and analyzation, and improvement had also acted as a mediator between the relation of quality managements source and outcome.

On this research, recognizing that ship inspection is closely related in improving ship safety', the importance of active quality managements of ship inspection has been notified. This paper aims to explore effective ways to improve inspection service and develop customer-centered inspection administration, by carrying out a case study on K Company. The methods applied for this research project are as follows, 1) sector-based examination of the existence of the ISO 9001 system; 2) evaluation of the operation of the system; 3) conduction of a survey questionnaire with the participation of all staff and inspection companies to analyze customer satisfaction of their inspection service, and 4) statistical analysis of the data collected from the survey questionnaire.

In the field of ship inspection in South Korea, due to outdated workflow processes, there is a possibility of tampering with inspection results. Accordingly, research is being conducted to prevent tampering with inspection results by introducing blockchain technology and cloud-based systems that allow real-time tracking and sharing of data, and to establish a transparent and efficient communication system. In this study, unit and integrated processes for overall data management and inspection execution related to ship inspection were implemented to automatically collect, manage, and track various inspection results occurring during the ship inspection process. Through this, it aimed to increase the efficiency of the ship inspection process overall, inducing growth in the ship inspection industry as a whole. The implemented web portal reached a level where trend analysis and comparative analysis with other ships based on inspection results are possible, and subsequent research aims to demonstrate the excellence of the system.

The maintenance of a ship is essential for safe navigation and hence regular surveys are prescribed according to the rule of classification societies. A hull inspection is generally performed by professional divers, but it takes a long time and the efficiency is low in terms of time and cost. In this research, a ROV(Remotely Operated Vehicle) named as SNU-ROV(Seoul National University-ROV) is developed to replace the conventional inspection method. In this system, the ROV is intended to be used for inspecting ship and harbor because harbor inspection is merging as a safety measure against any possible terror actions. In order to increase the efficiency of inspection, the ROV must be able to measure the exact position of damages. SNU-ROV has a positioning system based on LBL(Long Base Line). In shallow water such as harbor, however, LBL has bad DOP(Dilution of Precision) in the depth direction due to the limited depth. Thus LBL only can not locate the exact depth position. To solve the DOP problem, a pressure sensor is introduced to LBL and a complementary filter is attached by using indirect feedback Kalman filter. Thus developed positioning system is verified by simulation and experiment in towing tank.

Port State Control (PSC) is the inspection of foreign ships in national ports for the purpose of verifying that the condition of the ships and its equipments comply with the requirement of international conventions and the ship is manned and operated in compliance with applicable international laws. On the other hand, check items in PSC are nearly similar to periodical survey of Classification Societies, because they have the same background regarding safety and maritime pollution prevention. The purpose of this study is to develope computer-aided information system for ship inspection item which is useful for effective implementation of Port State Control. For this work, the status of PSC is reviewed, and the related scheme of ship survey system in Classification Societies is investigated. On these bases, a computer software integrated database system and object-oriented technique is developed. The developed system is expected helpful to establish and maintain an effective system of Port State Control.

According to the statistics of marine accidents occurring in Korea since the past 10 years, the proportion of small fishing boats having a gross tonnage of less than 10 tons was confirmed to be as high as 47.51% of the total marine accidents. Additionally, the trend of marine accidents involving small fishing boats has been increasing steeply compared with that of other ship types/sizes (gross tonnage); hence, countermeasures must be prepared urgently. The Korea maritime transportation authority proposed the introduction of a self inspection system to improve the ship inspection system of small fishing vessels. Futhermore the Ministry of Oceans and Fisheries recently prepared and implemented the 'Remote Method of Vessel Inspection Guidelines' to introduce non-face-to-face inspection methods. In this study, a self inspection approval system was presented as a method for reducing marine accidents of small fishing vessels. Moreover, a mobile application was developed to prepare a standardized remote method, and its effectiveness was analyzed. Resultantly, the necessity of introducing a mobile application-based ship inspection system was confirmed with the introduction of a self inspection approval system that could induce voluntary safety management in fishing vessel owners. Additionally, we confirmed that the self inspection approval system could effectively reduce marine accidents by raising the safety awareness of ship owners.
