The maritime autonomous surface ship is automatically collects and manages various information necessary for the operation to minimize human intervention and safely perform the mission assigned to the ship. And the ship may autonomously operate the partial or entire route to the destination determined by the ship himself. This ship navigation technology allows partially remote control the ship to be operated if necessary. The maritime autonomous surface ship (MASS) should collect and manage signals of various navigation communication equipments and engines mounted on the ship for safe operation. This requires a common platform technology. In this paper, we propose a common platform that is the core of smart ship implementation. Territorial authorities and ships are connected by satellite or terrestrial communication. In such a communication environment, information is exchanged smoothly in real time. This allows the onshore authorities to monitor ships and provide remote control to enable safe vessel navigation at sea.

자율운항선박(Maritime Autonomous Surface Ships, MASS)은 4수준으로 구분되는데, 현재 세계적으로 수준 2-3 사이의 원격제어 자율운항선박이 상용화를 시작할 것으로 조사되었다. 원격제어 자율운항선박은 3 주요요소(MASS, 해상위성통신, 원격제어자)로 구성되는데, 주요한 문제는 통신 손실이다. 자율운항선박의 원격제어는 해사 위성통신을 이용할 수밖에 없는데, 이러한 해사 위성통신은 통신두절, 대용량 데이터 송수신에 의한 지연 등이 문제로 대두되고 있다. 본 연구의 목적은 제어 데이터 송수신 과정에서 발생하는 지연시간이 충돌사고에 미치는 영향을 식별하기 위한 것으로, 우선하여 이러한 영향을 식별할 수 있는 실험방법을 고찰하고자 한다. 실험방법은 선박조종시뮬레이터를 이용할 것인데, 그 이전에 제어지연이 발생하는 메카니즘을 구현하고, 이러한 메카니즘에 의해서 정량적 및 정성적 분석이 가능한 방법론을 검토하였다. 본 연구는 자율운항선박에서 발생할 수 있는 제어지연이 항해안전에 미치는 영향의 과학적 식별과 평가에 관한 하나의 기반이될 것으로 기대된다.

The congestion situation of Korea's port is further inclining due to the number of arriving and departing vessels and increase in the size of the size. Indicators for assessing whether the Vessel Traffic Congestion is called the Marine Traffic Congestion and it is used as a diagnostic entries in the Maritime Traffic Safety Audit System. In the diagnostic system, 6L (longitudinal) X 3.2L (transverse) is used as ship's domain in cases of harbor. This study is to determine the safety distance of the VTS officer and the ship operators by targeting the Busan harbor, which has the most number of ships that arrive/depart in Korea and listen to the communication of the VTS and calculate the communication time of the VTS officer and the ship operators for 7 days. By utilizing the distance communication port, the safety distance between the controllers and the ship operators is derived. It can be used for basic information of VTS Officer and Ship's operator's Safety distance in Busan port's in&out harbor.

In the past, regional pilot service is provided by individual pilots directly on board each ship, but it will be difficult to provide this type of service in the near future when autonomous vessels are activated. This can be seen as the need for automation and intelligence of pilot service and provision of remote control system. In this paper, we propose a method, system, and service target that can carry out the electronic pilot service through the intelligence aids to navigation for smart port operation.

As global warming continues, the rate of ice melting in polar regions is increasing rapidly. The interest related to north polar route is increasing among not only countries near Arctic ocean but also the other countries, In the past, the classification society rule related to a design and operation of ship operating in polar area has been primarily amended by Russia, Norway and Finland located near Artic area. However recently International Maritime Organization decided to legislate the Polar Code to ensure safety of a ship operating in Arctic and Antarctic Ocean, and it is scheduled to be completed until 2014. The present paper focuses on the survey of the current enactment trends of Polar Code and suggests the confrontational strategy in related organization.

Because of increasement on the transportation of goods by ship and the operation of coastal ships for leisure, the interest of marine parts is growing up lately and then the safe navigation of ships are essential. In these circumstances, it is necessary that it should be examined the regulation of vessel traffic control in effect. Therefore, the wave height is analyzed on korean coast, and then the seakeeping performance with the wave height and the various hull types on operating on the coast is evaluated. These results will be helpful to the improvement of the regulation of vessel traffic control and safe navigation of coastal passenger ships.

IMO MSC 에서 제안된 E-Navigation 개념은 전자정보통신기술에 기반한 선박과 육상간 해양정보의 수집, 통합, 교환, 표현, 분석 풍을 통해서 항행 안전과 효율을 높이고, 해양환경을 보호하는 항행서비스를 개선하는 것이다. E-Navigation 전략을 개발하고 E-Navigation 환경을 구축하는 과정에서 해상교통환경의 주체가 되는 관제센터와 운항 선박의 정보교환 연동 시뮬레이션은 E-Navigation 환경 구축에서 중요한 의의가 있다. 육상-선박간 연동 시뮬레이션을 통해서 E-Navigation의 다양한 정보 교환의 기술적 가치와 새로운 교통환경의 안전성과 효율성을 평가할 수 있다. 본 연구에서는 항만 관제 모의를 수행하는 VTS 시뮬레이터와 선박운항을 모의하는 선박운항 시뮬레이터를 통합 운영하여 고급의 교통 정보를 양방향으로 교환하고, 각 선박마다 차별화된 교통 정보를 제공받을 수 있는 방안을 마련하기 위한 E-Navigation 환경을 시뮬레이션하는 시스템을 연구하였다.
