  • The ship surveyor makes a scheme of reasonable ship operation by examining whether the ship has been properly constructed in accordance with the rule of classification societies and international conventions or whether the facilities of the ship in operation meet the standard stipulated by law. Even though the ship surveyors of classification society generally consist of people who have the skill of design or operation of a ship, it takes a long time to train a surveyor to the maturity level. This paper describes the development of survey simulator based on virtual ship environment that enables the surveyor minimize trial and errors to survey the ships. By using VR(Virtual Reality) based survey simulator, surveyors possibly achieve improvement of competence in survey quality by means of safe and immersive training environment. In order to improve the usability and utility of the VR simulator, the ship 3D model has been generated using 3D CAD model for design and production in shipyard. Through this, we suggested the possibility of consistent use of 3D model as the digital twin of a ship.

  • Questionnaire survey on performance requirement of ship’s speed such as not only accuracy but also response and robustness were carried out, and the experiments to survey the GPS performances of static and dynamic characteristics were carried out simultaneously. In this paper, the questionnaire survey focusing on docking maneuvering, some analytic results of the survey, the results of GPS performance, and the possibility of adaptation for docking maneuvering on SDME and GPS are discussed. Consequently, from the results of questionnaire survey the performance requirement of ship’s speed in docking/anchoring maneuvering have need under 1cm/sec on the standard deviation, and speed information from GPS was adopted to use maneuvering information in docking/anchoring.

  • Now, GPS survey is used on equipment from leisure to precise geodetic survey and nation admits the result of GPS survey. When surveyors perform precise GPS survey, they use post processing method but they greatly use real time processing method to consider field status. Especially, when surveyors measure the result of moving target, they use real time GPS survey to the best method. For this study, the author precisely surveyed distance of ship launching from shipyard on real time using real time precise GPS method. In this paper, the author compares and examines the accuracy of first real time precise GPS survey method nationally and the capability on use. And the author performed real time precise GPS survey in NOKBONG and 21C shipyard positioning at GEOJEDO.

  • The purpose of this study was to analyze whether the disposition effect, a behavioral finance theory, exists in decision-making for ship investment. A case study was adopted as the research methodology, and data obtained through narrative and questionnaire responses on decision-making for ship sales were analyzed from a behavioral finance perspective. The analysis found that the disposition effect had an impact on the decision to sell a vessel. The narrative responses revealed that some shipping companies tended to miss the opportunity to maximize ship sale profit because they sold their vessels readily and quickly before the price of the vessels had risen sufficiently. The questionnaire survey results indicated that the majority of the survey respondents chose to sell a ship whose price had risen slightly from the initial purchase price. Managers in charge of ship investment should examine whether the disposition effect exists in their decision-making when selling a ship.

  • 「선박안전법」은 선박의 감항성(堪航性, Seaworthiness) 유지 및 안전운항에 필요한 사항을 규정하고 있으며, 이와 관련해서 이 법 제10조에서는 선박소유자가 선박검사를 받은 후 해당 선박의 선박검사증서에 적혀 있는 내용을 일시적으로 변경하고자 하는 경우에 임시검사를 받도록 하고 있다. 이와 같은 조치는 이 법 제15조에 따른 선박검사 후 선박의 상태유지에 따른 것으로 여기에는 「항만법」 제39조제1항에 따른 "항만건설작업선"을 포함하고 있다. 그러나 항만건설작업선은 본래 부선(艀船)과 동일한 운용체계를 보이고 있음에도 불구하고 「선박안전법」을 적용받지 아니하고 「건설기계관리법」에 따른 등록 및 검사·점검을 받아오다 2012년 12월 14일 울산항만 내에서 작업 중 발생한 "석정36호" 침몰사고를 발단으로 2016년 「항만법」이 개정되면서 「선박안전법」에 추가해서 적용받게 된 점 등을 고려할 때 항만건설작업선을 「선박안전법」에서 정하고 있는 모든 규정을 따르도록 적용하는 것은 현실적 한계가 있다 할 것이다. 이에 따라 본 논문에서는 항만건설작업선의 개념, 등록, 작업구역, 검사규정, 임시변경 적용사례 등을 통한 작업특성 및 실제 항만건설작업선의 「선박안전법」 적용범위와 관련해서 논란이 되고 있는 사항 등에 대해 살펴보고, 또한 「항만법」의 개정에 따라 항만건설작업선을 「선박안전법」의 검사대상으로 편입하게 된 입법취지 등을 통해 「선박안전법」 제10조에서 규정하고 있는 임시검사 중 "임시변경"에 관한 사항을 적용하는데 있어서의 그 적정범위를 제시하고자 한다.

  • 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.
