최근 국내 일부 항해사들은 해운산업의 어려운 취업환경을 극복하고, 직업선택의 저변을 확대하기 위하여 승선경력을 기반으로 국내외 교육기관에서 DP운항사 교육을 이수하여 직종을 전환하고자 노력하고 있다. 그러나 아직까지 국내에서는 해양플랜트 서비스 산업 이 활성화 되어있지 않기 때문에 동 분야로 진출하고자 하는 항해사들은 어렵게 자격취득을 위한 실습을 마치고 대부분 해외선사로 진출 하고 있다. 그럼에도 불구하고 DP운항사로 취업을 희망하는 항해사들은 경력을 중시하는 해외 해양플랜트 기업의 보수적인 채용 절차, 비 영어권 출신자의 언어사용의 한계, 다문화 승선생활의 어려움, 필수 직무요건에 대한 체계적인 정보 부족 등의 이유로 구직 단계에서 부터 어려움을 겪고 있다. 따라서 이 연구는 DP운항사가 갖추어야 할 직무능력 및 자격 요건을 분석하여 국가에서 요구하는 최소한의 능력 수 준을 제시하고 있는 NCS 표준 개발을 위한 기초자료를 제공하고, DP운항사 전문인력양성을 활성화하기 위한 방안을 제시하는 데 목적을 두고 있다. 본 연구의 결과로서, DP운항사의 직무 분류, 직무능력표준 및 경력개발경로를 제시하였고, DP운항사 양성 활성화 방안으로서 DP 실습선박의 공동 활용, DP 전문 교원 양성 및 정부주도 NCS 수출모델을 제안하였다.

We have proposed modeling methods of mariners' standard behavior for collision avoidance by analyzing mariners' recognition process in a previous study. As a subsequent study, the aim of this study is to build a model of mariners' execution process which is one of six processes in the condition of collision avoidance. In this study, thus, the structure of mariners' information processing on the process of taking avoiding actions is described and the relation between mariners' behavior and necessary factors in the process is analyzed. And then we have built a model of mariners' standard behavior for execution process based on the characteristics of mariners in ship-handling, which are obtained from the international collaborative research on human factors. It is tried to define the contents of execution process based on the standard behavior of mariners for collision avoidance and to formulate information processing of mariners.

The safety degree of navigation for collision avoidance is closely related with the combination between mariner's behavior and navigational environment. The condition of navigational environment is mainly decided by navigable waters, ship traffic, rule of road, sea state, weather and so on. Especially, the condition of navigable waters and ship traffic in navigational environment are ones of the important factors to attain safe navigation when mariners are underway and crossing, head on or overtaking situation. Thus this paper is to analyze the characteristics of mariner's behavior for collision avoidance caused by ship traffic and navigable waters by analyzing the contents of questionnaire and the results of international collaborative research. As a result, it can be concluded that the density of ship traffic and the area of navigable waters affect mariner's ship handling for collision avoidance.

We've investigated the characteristics on mariner's behavior in the collision situation through a full-mission ship handling simulator and considered that it's necessary to model the standard avoiding behavior of mariners in order to apply the obtained results more widely and effectively. Thus we described the contents of standard avoiding behavior taken by mariners in the collision situation and established the concept of the standard model based on human factors for collision avoidance in a previous study. As a following study, this paper is to propose the method of modeling on mariners' standard behavior for collision avoidance by analyzing the contents of mariner's information processing and the related factors using regression analysis. As a result, we confirmed the influence of relating factors to avoiding behavior in mariner's deciding decisions and proposed the modeling method of mariners' standard behavior for collision avoidance with a example of recognition model.

Human factors have been considered the primary reason of marine accidents. Especially, the collision between vessels is mostly mused by human behavior. However, there have not been many researches to clarify the reason of marine accidents mused by human factors quantitatively. In order to understand human factors and to enhance safe navigation systematically, using a full mission ship-handling simulator, we've investigated the characteristics of avoiding behavior taken by mariners. Further in order to apply the characteristics more widely and effectively, it's necessary to formulate the standard behavior for ship-handling in the condition of collision avoidance. Is this study, therefore, we intended to propose the concept to model the mariner's standard behavior on the handling of collision avoidance as the first step. As a result, we confirmed the contents of information processing in ship-handling that mariner's generally taking to avoid collision.

It can be said that the relationship between the maneuvering ability of operators and the navigational environment affects the safe degree of navigation in the collision avoidance situation. In order to reduce the occurrence probability of accident and to maintain the safety, it is necessary to clarify the relationship between human behavior and navigational environment. In this study, therefore, we analyzed and discussed the relationship between the maneuvering characteristics and the safety focused on human behavior as a fundamental factor of marine accidents using ship handling simulator and questionnaire. As a result, we concluded that navigational environment changes variously and the maneuvering ability of operators also varies with the navigational environment, and the ship handling characteristics strongly affect the occurrence probability of accident.
