When maneuvering a ship in a narrow channel or under bridge, the ship operator may take actions of slowdown engine and altering course in order to avoid possible navigational dangers, which may reduce difficulties on navigation or collsion avoidance against other ship and/or bridge. In this paper, taking notice of the stress caused by these actions of slowdown engine and altering course, survey is carried out for whether it is possible to quantify the stress by time delay as an index. Based on the ship handling simulator experiment, it is verified that difficulty of navigation changes is highly correlated with the time delay, which result from compensation actions of slowdown engine and altering course.

In this paper, we proposed an image shaking index to evaluate the remote controllability of vision based unmanned vehicles. To analyze the usefulness of the proposed image-shaking index, we perform subjective tests using a virtual unmanned vehicle driving simulator. The developed driving simulator consists of a real-time multibody dynamic software of the unmanned vehicle, a motion simulator, and a driver console. We perform dynamic simulations to obtain the motion of the unmanned vehicle running on the various road surfaces such as ISO roughness level A~E roads. The motion of the vehicle body is reflected in the motion simulator. Then, to enable remote control operation, we offer to operators the image data that was measured using the camera sensor on the simulator. We verify the usefulness of the proposed image-shaking index compared with subjective index provided by operators.

This paper represents the development of a CLS(Control Loading System) for a target a airplane (KT-1) with mechanical linkage reversible flight control system. The system is composed of mechanical frame, controller, sensing part to measure the force from the stick, driving system generating the reaction forces. The DS1103 DSP(Digital Signal Processor) of the dSpace Corp. was used as the controller. The control algorithm of the CLS and the operational environment including monitoring software and evaluation tools are described. The evaluation of the system was conducted according to the requirement specification. The results of the test were analyzed by comparing with the actual data of the target airplane.

The purpose of the present study was to investigate the effect of mariner's situation awareness(SA) training on navigation performance using a full mission ship-handling simulator. For this purpose, the mariners were trained in terms of various aspects of SA. Independent variables such as risk levels of ship-to-ship collision, navigational route types of 'target ship(TS)', and number of ships around the own ship(OS) were systematically varied, and dependent variables of closest point of approach(CPA) between TS and OS, number of collision, types of collision-avoidance strategy were measured The results can be summarized as followings. First, training on mariner's SA appeared to induce improved performances in various aspects of ship handling. Second, mariners in the routine navigation situation where TS had priority following maritime rules seemed to suffer to prepare collision avoidance when the TS altered its route. However, this tendency greatly reduced after the training These results suggest the benefit of mariner's SA training on maritime safety.

Yaw-checking and course-keeping ability in IMO's ship manoeuvrability standards is reviewed from the viewpoint cf sole navigation Three kinds of virtual series-ships, which have different course instability, are taken as test models. The numerical simulation on Z-test is carried out in order to examine the correlation between known manoeuvrability in spiral characteristics and various kinds of overshoot angle. Then simulator experiments are executed with series-ships in a curoed, narrow waterway by six operators(five active pilots and one ex-captain) in order to examine the correlation between known manoeuvrability and degree of manoeuvring difficulty. IMO criteria for yaw-checking and course-keeping ability are discussed and revised criteria are proposed.

Recently, in the process of developing, verifying, and upgrading the e-Navigation service and autonomous navigation system, there is an increasing demand for inter-working with a ship-handling simulator that can simulate actual maritime traffic conditions. In this paper, to develop a ship-handling simulation system based on actual maritime traffic conditions, a simulation server was built, received information on the actual maritime traffic conditions from the e-Navigation linkage system, and changed to information for operating the ship-handling simulator. In order to provide simulation images to users, 3D shape modeling for trade ports, coastal ports in Korea and major type of ship were performed. The developed system will be used for the advancement of e-Navigation service, development and verification of autonomous navigation systems, by enabling simultaneous processing of more than 10,000 ships and allowing users to simulate actual maritime traffic conditions in the desired area.

현재 건설 중인 제주 강정항에 15만톤급 크루즈 선박의 운항안전성 여부를 판별하기 위하여 3차례의 선박조종 시뮬레이션 평가를 실시하였다. 국내 초대형 크루즈 선박의 조종성능에 대한 연구가 미비했고, 크루즈 선박의 조종성능을 정확하게 선박조종 시뮬레이터에 반영할 수 없었던 시스템적인 한계로 인해 초대형 크루즈 선박의 운항 안전성 평가 결과는 사회적으로 많은 갈등과 마찰을 초래하였다. 본 연구에서는 세계적인 초대형 크루즈 선박의 조종특성을 바탕으로 제주 강정항 건설 과정에서는 논란이 되었던 수역시설의 적정성을 검토하고자 선회장, 항로 법선, 방파제 통과 선속 등에 대하여 국내외 각종 설계지침과 실측 자료, 항만 운영 사례 등을 심층 분석하였다. 초대형 크루즈 선박의 우수한 추진 및 조종성능을 감안하면 제주 강정항의 수역시설 규모는 적정하다고 판단되며, 초대형 크루즈 선박의 안전 입출항에도 별다른 문제는 없을 것으로 사료된다.

해상교량의 규모 결정을 위한 선박조종시뮬레이션 표준시행 조건 및 기법(대상선박 설정, 시나리오, 시행회수, 평가기법 등)을 정립함으로써 해상교량 통항 안전성을 평가하는데 정책 결정의 혼선을 최소화 할 필요가 있다. 본 연구에서는 과거 수행된 선박조종시뮬레이션 관련 보고서 분석 및 평가를 기초로 선박조종시뮬레이션 표준안에 대한 공통점을 도출하여, 국내 선박조종시뮬레이터 보유기관 항만 이용자 및 항만 건설 관계자 등의 의견 수렴과정을 거쳐 수정 보완함으로써 선박조종시뮬레이션의 대상선박, 수행 조건, 평가기법, 시나리오 설정 등에 대한 최종 표준안을 제시한다.
