자율운항선박 등 스마트선박에서 항로상의 해양환경 상태를 관측·예측하는 과정은 필수요소이며 선박 통신을 고려했을 때 선박자체에서 취득할 수 있는 정보만을 이용하여 의사결정이 가능하도록 해양환경 정보를 생산하는 기술이 필요하다. 이에 본 연구는 짧은 시간 내에 해상 변화를 예측할 수 있는 인공지능(딥러닝)기반의 예측기법을 개발하였다.

Marine disaster, such as 'Dolphin Lake ship', "the Sewol ferry', on the ocean needs emergency communication with land post and Rescue services. It needs of emergency communication system has increased in Republic of Korea peninsula with the sea on three side. The system will be more fully equipped to deal with disasters linked to communication so alone sailing ship is at sea. Research is needed on communication links to submarines operated by submarine to sink a ship, as well as immersion in the sea with. And it is necessary in the study of the land in preparation for the emergency disaster ship and submarine communication links for offshore and subsea oil and associated communication systems. Will be studied in preparation for the communication protocols and emergency and disaster location and land the plane or for a career in the satellite systems are linked through this.

This study identified necessary navigational support services to prevent accidents through an examination and a survey on the navigation and communication systems of non-SOLAS ships. The functional and operational requirements for the identified navigational support services were discussed accordingly. Among the navigational support services proposed are an Electronic Navigational Chart (ENC) service, a route planning service, an operation monitoring service, and collision prevention support services for ships in coastal areas. To facilitate the identified navigational support services, ship navigation system, shore supporting centre and maritime communication network were discussed as a digital infrastructure. The operational methode for the digital infrastructure were discussed in the service scenarios for ships carrying dangerous cargo, large ships over 200 meters in length and high speed passenger ships over 15 knots in speed. This study will facilitate the development of policies for the improvement of ship operation management in Korean coastal waters and will contribute to improving the navigational safety of non-SOLAS ships.

In the maritime digital forensic part, it is very important and difficult process that analysis of data and information with vessel navigation system's binary log data for situation awareness of maritime accident. In recent years, analysis of vessel's navigation system's trajectory information is an essential element of maritime accident investigation. So, we made an experiment about corruption with various memory device in navigation system. The analysis of corruption test in seawater give us important information about the valid pulling time of sunken ship for acquirement useful trajectory information.

The Smoke Detect System is setup to extinguish early a fire on the large ship like as the cargo ship and Bulk Carrier at sea. The Addressable Type Smoke Detect System that keeps the advantages and dispenses with the disadvantages of the existing conventional type system is composed of only one electrical cords. In this paper, we make the Smoke Detect System of an addressable type and implement to control it using ATmega Micro-controller and evaluate it.

선박이 배출하는 안정수(ballast water)는 외부로부터 유해 생물들이 유입되어 전파해 오는 주요경로로써, 해양환경 변화를 초래하는 매우 중요하고 위험한 일중의 하나이다. 그러나 이에 대한 효과적인 처리방법은 아직까지도 미흡한 상태이다. 선박 안정수에 포함되어 타 지역으로부터 옮겨지는 외래침입생물 처리 방안의 하나로, 강 전리방전 기술을 적용하여 고 밀집 산소와 물분자로부터 고농도 수산자유기(OH: hydroxyl radical)를 전리, 발생시켜서 활성입자를 신속히 확산시켜 비교적 낮은 수산기농도 하에서 유해성침입생물을 소멸 처리하는 환경 친화적 녹색 청정처리방법을 제안하였다. 제안된 기술은 대상물의 처리 후 부수적으로 발생할 수 있는 처리잔류물이 전혀 발생하지 않으며, 인공적 화학성분의 약제를 사용하지 않는 저렴한 처리방법이므로 대ㆍ소형 원양선박의 안정수에 들어있는 외래침입생물의 타 지역 해양확산을 안전하게 처리할 수 있는 자연치유적 신기술이다.

Shipbuilding is an order made assembly production basically. To build a single vessel, it costs hundreds of thousands small and big parts and million tons of structural steel. From contract to delivery, It takes 2 years of time in general. Shipbuilding parts are supplied order made based in and out of the country. For the cost and efficiency issue, on-time supply of ship parts is critical. Thus, this study suggests the optimum material management system plan of ship components for the best result.
