IMO introduced the concept of e-Navigation and proposed MSPs(Maritime Service Portfolios) concept to reduce marine accidents, to improve efficiency of ship operation, port operation, and ship operation technology. Korean e-Navigation defines S1 ~ S5 services, as the service concept focused on domestic e-Navigation service corresponding to IMO MSPs, and is constructing a system as an ongoing project. S2 service (onboard system remote monitoring service) among the concepts of Korean e-Navigation services, is a service concept that judges the emergency level according to risk if an abnormal condition occurs during navigation, and provides corresponding guidance to accident ships based on emergency level. The purpose of this paper is to provide a basic architecture proposal of Korean e-Navigation S2 service navigation safety module, based on the S2 service operation concept. To do this, we conducted a questionnaire survey to ask experts with experience with sailors, to respond to the subjective risk experienced by sailors considering effects of anomalies, including equipment failure relative to sailing and navigational safety. Risk level for each abnormal condition was classified. The basic algorithm design of the navigation safety module is composed of safety index (SI) calculation module based on results of questionnaire and expert opinions, safety level (SL) determination module according to safety index, and corresponding guidance generation module according to safety level. To conduct basic validation of basic architecture of the navigation safety module, simulation of the ship anomaly monitoring was performed, and results have been revealed.

The Korean e-Navigation system is a Korean approach to correspond with implementation of IMO e-Navigation. It provides five services, among them SV20 service, a ship remote monitoring system that collects and processes sensor information related to fire, navigation, and seakeeping performance safety. The system also detects abnormal conditions such as fires, capsizing, sinking, navigation equipment failure during navigation, and calculates the safety index and determines the emergency level. According to emergency level, it provides appropriate emergency response guidance for the onboard operator. The fire safety module is composed of three sub-modules; each module is the safety index sub-module, the emergency level determination sub-module and emergency response guidance sub-module. In this study, operational concept of the fire safety module in SV20 service is explained, and fire safety assessment factors are estimated, to calculate the fire safety index. Fire assessment factors included 'Fire detector position factor,' 'Smoke diffusion rate factor,' and 'Fire-fighting facilities factor.'

As a sense of practical field, most researchers emphasize the importance of safety management to prevent marine accidents. The purpose of this paper is to develope a new safety evaluation method using Safety Index (SI) which is to measure the emotional feeling of navigation officer by traffic situations. In this study, the questionnaires with SI are used to investigate the degree of sensing levels of navigation officers according to the navigation situations. In addition, the traffic data obtained from AIS (Automatic Identification System) data are used to give actual situations in the questionnaire investigation. As results of questionaries investigations based upon the AIS data, it is shown that the Safety Index can be used as a criterion to determine the safety levels of ship navigating in a coastal areas.

육상에 비해 위험도가 높은 해상에서의 항해를 지원하기 위해 수많은 해상안전기술 및 체계가 개발되고 있다. e-Navigation은 해상안전을 위한 대표적인 체계로, 현존하는 대부분의 해상안전기술을 집약시켜 선박 안전 지원을 극대화할 수 있도록 개발되고 있다. 이 e-Navigation 체계는 국제해사기구(IMO)에서 2019년까지 도입을 목표로 개발을 진행하고 있으며, 한국은 해상안전지원기술의 중요성을 이미 인식하여 e-Navigation을 적극도입하고 있다. 한국형 e-Navigation은 최적안전항로 제공, 위험도 분석, 기상 정보 제공등 해상안전을 위한 다양한 기능을 제공하도록 설계가 진행되고 있으며 각 기능을 제공하는 서비스 모듈은 하나의 데이터베이스로 구성하기 힘든 각기 다른 종류의 데이터를 사용한다. 이에 본 논문에서는 한국형 e-Navigation 운영 시스템에서 필요로 하는 데이터를 분석하고 이를 효과적으로 지원할 수 있는 데이터 서비스 시스템 구조와 종류를 분석하였다.

The recent huge maritime casualties and their environmental impacts showed that human error in ship navigation is one of the primary causes leading to accidents. In order to reduce maritime accidents and human errors in ship navigation, it is very important and urgent to improve the skills of navigators and develop advanced navigation support system for ship operations. For example, a SCMS(Ship Control and Management System), INS(Integrated Navigation System) and PCS(propulsion Control System) which are considered as a ship automation system was operated in ship. Furthermore, the most recent automation ships collision incidents warn us that only making automation ships alone is not sufficient for improving ship safety. Effective interaction between officer and ship automation system is essential for safety. In this paper, the interactive relationship between officer and the ship automation system was studied, then the research result for reducing maritime casualties will be presented.
