The anchorage among harbour facilities should ensure sufficient water surface area for safe anchoring. A general method is to consider the L.O.A of the target ship and the depth and bottom quality of anchorage to calculate the water surface area of anchorage. However, the gross tonnage is used as a unit of the ship capacity standard of anchorage based on the detailed rules for harbour facilities operation in Korea. In this study, the gross tonnage is converted to L.O.A to calculate the actual anchoring radius of the target ship. This actual anchoring radius exceeds at 25 anchorages (among 90 anchorages) compared with the designated water surface area. Therefore, as an improvement plan of the ship capacity standard for anchorage, L.O.A should be used as a unit for anchorage based on the detailed rules for harbour facilities operation and related Korean maritime laws.

The criteria of operating anchorage and the unit of anchorage capacity have not been unified and the different terms have been used in same matters in each regulations related to the anchorages provided in major domestic ports. The competent authorities and vessels which are going to use anchorages are confused due to those situations. This paper suggests the schemes to unify criteria of operating anchorage, the unit of anchorage capacity and terms used in same matters through reviewing the anchorage operating regulations provided in major domestic ports. In addition, this paper suggests that the principles of anchorage naming, the unit of anchorage capacity and the number of vessels that can be accommodated should be established at the next revision of regulations through reviewing the status of anchorages in major foreign ports to minimize the confusion on operating anchorages.

Ships are built according to the purpose and operated with individual goals. Operational goals are reflected in the design of the ships and become the main criterion for determining the required ship ability. In general, cargo ships and passenger ships are objectively evaluated in terms of the operation part of the ship and the capacity part of the cargo or passenger, centering on their transportation ability. In consideration of the required ship ability, the built ship can expect effects such as economic feasibility and eco-friendliness in addition to basic characteristics such as stability. Accordingly, the concept of ship ability is expected to be effectively used in the field of training-only ship management by each institution, which plays a pivotal role in training ship-officers. In this study, the basic direction was verified for the ship ability evaluation criteria of training-only ships through the analysis of the internal space of two training-only ships of the Korea Institute of Maritime and Fisheries Technology, which were recently built with a time lag. In the process of building training-only ship or general-purpose training ship, the possibility of using the ship ability standards in securing budget and designing was derived.

본 연구에서는 승선환경에 관한 기초연구로서 승선 및 유람선 터미널의 공간 및 시설과 관련된 법적 문제에 대한 분석을 수행하였다. 연구결과는 다음과 같다. 1) 육상대중교통의 탑승과 관련된 법령과 규정에 비해 시설별 세부규정이 미흡하고, 유람선터미널 역시 탑승객 수용능력별 시설기준이 요구된다. 2) 터미널의 대기공간과 승강장은 법에 따라 기본시설이 갖춰지지 않은 곳으로 탑승능력을 수용할 수 있는 좁은 공간이다. 3) 현측 접안과 선수측 접안을 유람선 선착장의 승강 공간과 사용 시설 등을 고려하여 적절히 사용해야한다.

Relocation and expansion of existing port facilities are necessary given this increase in marine traffic volume and the presence of larger entering vessels. Therefore, this study focused on anchorage among water facilities, and examined the degree of harmony between anchorage and other water facilities at Yeosu Kwangyang Port. The number of anchoring vessels in relation to anchorage over the past 5 years, total anchored hours by anchorage-years, average number of simultaneously anchored vessels by anchorage-years, maximum number of simultaneously anchored vessels by anchorage, and maximum size of anchored vessels by anchorage have been surveyed. The minimum anchorage radius has been calculated according to the designated anchorage capacity according to anchorage. Finally, improvement plans for Yeosu Kwangyang Port's anchorage have been suggested, including relocating of Yeosu no. 2 anchorage, expanding of Kwangyang no. 1 ~ 5 anchorage, relocating of Kwangyang no. 8 ~ 9 anchorage, and repealing of Kwangyang no. 11 anchorage.

최근 우리나라에서는 해양사고의 효과적인 예방을 위하여 구축 중인 한국형 e-Navigation SV20-선내시스템 원격모니터링 서비스에서는 복원성, 화재, 침수, 과도경사, 항해장비의 이상과 같이 선박의 안전 운항과 직접적으로 관련이 있는 선박의 센서들을 수집, 분석하여 이상 상태와 긴급상황을 자동으로 식별하여 안전운항을 지원하는 기능이 있다. IMO 선박안전관리 시스템의 경우 선원의 인적 과실에 의한 해상에서 안전 및 해양환경 보호를 위한 핵심 요소로서 우리나라는 SOLAS 협약 제9장(선박의 안전운항을 위한 관리)및 ISM CODE를 1999년 2월 해사안전법에 수용하여 2002. 7. 1.부터 단계적으로 시행하고 있다. 이 연구에서는 이 둘의 융합 개념의 기술적 결합을 통한 체계적이고 자동화적으로 선박에서의 안전관리 능력을 제고하여 안전 사고 발생을 최소화 할 수 있는 여러 가지 시스템과 더불어 사고 발생시 효율적으로 대응할 수 있는 표준 토폴로지 기반 UI 및 항차 기반 위기대응 가이던스를 개발 하고자 한다.

Vessel Traffic Service (VTS) increases the efficiency of maritime traffic in terms of reducing marine accidents and the efficient use of port facilities. This means that ports and waterways have their own capacities and can be safely adapted to their capacity through proper traffic management of the VTS. Proper traffic management can reduce the number of vessels and unnecessary waiting in ports, which can lead to economic benefits of ups and port terminals. On the other hand, Korean ports and waterways have restrictions on the maximum speed for safety, but there is no restriction on the minimum speed. However, ships that operate at low speeds in ports and waterways may be able to occupy long periods of operational routes, which may impede efficient port operation. Therefore, the purpose of this study is to propose the minimum speed of ship for efficient port and waterway use. To this end, we reviewed the current laws and systems and proposed the appropriate minimum speed in the waterway using the theory of queue.

Most q the domestic container terminals are inferior to throughput q container. The reason why they have the difference between the handling capacity q planed quay and its real. By putting into quay handling equipment, the productivity of quay can be improved, waiting rate q the ship can be lowed. This paper suggests more resonable terminal construction, throughout comparing with previous construction way, improved handling capacity and the economical efficiency of equipment costs, labor costs, construction costs, operation costs on change of terminal size by adding the equipment.

Due to the fast growing rate of the global container trade, every major port is under the pressure of meeting the projected capacity demand. As a result, alternative solutions have been sought for improving capacity and meeting the growing demand for container storage area and terminal capacity. Moreover, material handling process re-engineering is now a critical issue for logistics and supply chain managers of airline, shipping lines, terminal and warehousing enterprises around the world. Therefore, the purpose of this paper is to develop the 3D simulator for executing performance valuation of port transportation systems. The developed 3D simulator system is to measure the effectiveness of the proposed total system and compare it with existing practices. The performance analysis variables are also defined for these comparisons.

National fishing harbour is as a refuge for fishing boats and a breakwater lighthouse is installed as a functional facility in consideration of harbour identification and the safety of passing vessels. In this study, the service level of breakwater lighthouse (234 units) was estimated based on the traffic volume of 105 national fishing harbour. For this purpose, the evaluation items were determined, the fishing harbour standard index was calculated (Fs=1), the proximity of fishing harbour was identified and the function (service level) of the breakwater lighthouse was estimated in the following order. However, national fishing harbour differed in size, traffic volume and fishing vessel capacity. Therefore, 105 national fishing harbour were divided into three groups through cluster analysis. The cluster analysis was based on the service level factors of the breakwater lighthouse, such as the number of weeding fishing vessels, tonnage of fishing vessels, the number of incoming and outgoing vessels per year, and fishing vessel capacity. As a result of the estimation, the service level of the breakwater lighthouse (light tower height, visual height, visual range, interval) was 10.50m, 16.50m, 7.00mile, 5.5sec for group 1, and 10.67m, 16.16m, 8.33mile, and 6.0sec for group 2, The three groups are 11.53m, 16.75m, 6.75mile and 5.0sec. The results of this study can be used as useful basic data for improving the service level of traffic vessels when a breakwater lighthouse is built in a fishing harbour in the future.
