2020년 4월 부산신항에서 발생한 밀라노 브리지 사고는 초경하상태 선박의 조종성능 저하에 대한 큰 관심을 일으켰다. 본 연구는 흘수가 과도하게 작은 상태의 선박의 조종성능 저하에 대한 기초연구로 진행되었다. 이를 위하여 다양한 문헌 검토, 실증시험 및 시뮬레이션테스트를 진행하였고, 흘수가 지나치게 작은 선박은 만재 상태에 비하여 선회권의 크기가 커지므로 이에 대한 주의가 필요하다. 각 도선구에서는 입항하는 선박의 흘수가 지나치게 작을 경우 이를 제한하는 규제 도입에 대한 검토가 필요할 것으로 사료된다.

황산화물, 미세먼지 등 대기환경의 오염원은 선박이 많은 비중을 차지하고 있다. 오늘날 인간은 해양을 삶의 영역을 넓히고 있다. 하지만 해양에서 대기환경을 측정할 수 있는 방법은 제한이 되어있다. 해양에는 선박의 안전항해를 도모할 다양한 종류의 항로표지가 설치되어 있다. 따라서 항로표지를 이용하여 해양의 대기환경을 측정하여 해양과 밀접한 관련이 있는 국민에게 서비스하고자 한다.

Since emergency response training for maritime safety and safety education of maritime education institutions are conducted based on the set scenarios and education contents, there are limitations in the reduction of human error and response to various situations. Although there is a need for improvement, there is no way to improve response capabilities by assessing existing education training and securing diversity in situations. This study proposes a theoretical procedure analyzer method to model the diversity of situations for the improvement of emergency response training. This paper defines the human and system theoretical procedure analysis model (HSTPA) based on the organic relationship of the source and system. The limitations of the existing training were derived by analyzing the errors that each component could produce and applying them to the fire response training scenarios requiring vertical reporting systems and responses. The segmentation and inspection of training scenario considerations applying the proposed HSTPA model is believed to help create diverse and realistic scenarios in emergency response training and education, and improve the situation judgment understanding and response capabilities of the subjects.

The International Maritime Organization (IMO) is promoting the introduction of e-Navigation that prevents maritime accidents by fusion of Information & Communication Technology (ICT) with ship operation technology. In Korea, Korean e-Navigation is also being developed for fishing vessels and small vessels sailing offshore, which are vulnerable to maritime accidents. However, for the successful development of Korean e-Navigation, it is necessary to develop an indicator that can evaluate the development performance so that the development performance that has been progressed so far can be evaluated and the development direction can be re-established. Therefore, this study attempted to develop an evaluation index tailored to the development goal of e-Navigation service centering on the collision accident, which is a major maritime accident. In this study, a collision accident evaluation index for e-Navigation service was developed by deriving and quantifying the root cause of maritime collision accidents using Root cause analysis(RCA) and fault tree analysis (FTA) techniques. This indicator is considered to be helpful in reducing maritime accidents as it is used as a development indicator for e-Navigation and an indicator for maritime collision accident analysis.

Marine Incidents based on Heinrich's law are very important in preventing accidents. However, marine Incident data are mainly qualitative and are used to prevent similar accidents through case sharing rather than statistical analysis, which can be confirmed in the marine Incident-related data posted in the Korea Maritime Safety Tribunal. Therefore, this study derived quantitative results by analyzing the causes of marine incidents during berthing using various methods of statistical analysis. To this end, data involving marine incidents from various shipping companies were collected and reclassified for easy analysis. The main keywords were derived via primary analysis using text mining. Only meaningful words were selected via verification by an expert group, and time series and cluster analysis were performed to predict marine incidents that may occur during berthing. Although the role of an expert group was still required during the analysis, it was confirmed that quantitative analysis of marine incidents was feasible, and iused to provide cause and accident prevention information.

Regulations to reduce greenhouse gas emissions from ships are gradually being strengthened. EEXI (Energy Efficiency Existing Index) has been introduced in existing ships, and various studies are aimed at achieving the greenhouse gas emission reduction target are currently underway. In this study, we proposed a method to reduce greenhouse gas emissions through reducing fuel oil consumption by applying a solar power generation system to a pure and truck carrier among existing ships engaged in international voyages. The proposed photovoltaic power generation system consists of a photovoltaic module, an energy storage system, and a power conversion device. To confirm applicability, the system was modeled through a power electronics program, and a simulation was performed. In addition, economic analysis was conducted to check the feasibility of application to real ships, and it was confirmed that significant results were derived in the economical aspect after about 11 years had elapsed.

The International Convention on Standards for Training, Certification, and Watchkeeping of Seafarers (STCW) outlines the qualifications that maritime cadets must meet in order to serve as merchant marine officers. Maritime English is one of the most essential qualifications for STCW, and each national authority is implementing Maritime English education that complies with national and international regulations. In this study, an English proficiency background survey was conducted to investigate the factors related to the Maritime English skills and competencies. In line with this, maritime cadets utilized the Standard Maritime English Communication Phrases (SMCP) learning platform to track their learning progress and its efficacy. This study examined the applicability of the automatic scoring platform for Maritime English education, as well as its future potential for widespread use in the maritime education field.

국제해상충돌예방규칙(COLREGs)에 관한 협약은 해상에서 발생하는 충돌사고를 방지하기 위한 규칙으로 구성되어 있으며, Seaman(선원)의 Qualitative Rule(질적 규칙)과 Ordinary practice(통상적인 관행)에 기초하고 있다. MASS의 출현으로 인하여 질적 규칙과 관행으로 인하여 COLREG를 기반으로 한 항법 해석의 기준의 다름이 발생하였고, 기준의 차이로 인해 충돌 상황에 대한 항법 해석의 모호성문제가 발생하고 있다. 따라서 본 연구는 COLREG의 항법 해석의 모호성을 규명하여 유인과 무인 사이의 충돌회피 상황을 명확히 하는 것을 목적으로 한다. COLREG를 기반으로 한 충돌 상황의 모호성을 식별하기 위해 실제 항해사를 대상으로 충돌 회피 상황에 대한 인식을 조사하고, 정면 및 횡단, 횡단 및 추월 상황을 기반으로 조사 결과를 분석하였다. 분석 결과, 응답자들은 008°에서 마주치는 선박에 대해서 정면 또는 횡단 상황 항법 규칙을 적용해야 하는지, 160°에서 다가오는 선박에 대해서 추월 또는 횡단 상황을 적용해야 하는지에 대해 확신하지 못하는 것으로 나타났다. 이러한 결과는 이러한 모호성의 증가와 함께 충돌회피상황의 수동적 행동보다 능동적인 행동을 취함으로써 선원에 의한 충돌위험을 회피하려는 경향이 더 강해짐을 나타낸다.
