Development of safety monitoring system for workers in the ship building industry is currently under progress using RFID(Radio Frequency IDentification) for successful development of the U-BUSS(Ubiquitous- Safety User Safety System). For decades, RFID technology has become a key technology to provide the real-time location system of worker and is variously used for safety monitoring system to increase productivity, improve the blasting quality and enhance the safety of working condition in the ship building industry In this paper, 2.45GHz band RTLS(Real Time Location System) technologies and the ubiquitous safety monitoring system of the ship yard's blasting cell are described.

오늘날 해운산업분야에서 해상의 인명 ㆍ재산, 해양환경보호에 가장 큰 관심을 기울이고 있다. 국제해사기구 (IMO)에서는 해상에서 선박운항으로 인하여 발생하는 충돌, 좌초, 침몰 등 해양사고에 대한 위험성을 정량적으로 평가하여, 그에 대한 제어방안을 마련하고 합리적인 안전규정을 제ㆍ개정하기 위한 절차적 수단으로 FSA(Formal Safety Assessment)를 도입하여 과학적이고 체계적인 대응방안을 마련하고자 노력하고 있다. 따라서 본 연구에서는 FSA평가시스템을 이용하여 사고발생빈도와 사고로 인한 인적, 물적, 환경오염 피해가 막대한 선박충돌사고의 발생위험성을 분석하였다. 또한 선박충돌사고 발생에 가장 큰 영향을 미치는 위해요소(Hazard)인 인적요소(Human Factor)에 대해서 전문가집단의 의견을 수렴하여 FSM법을 이용하여 각 위해요소를 계층화하고, 요소 상호간의 관련성을 분석하여 선박충돌사고를 예방하기 위한 적절한 제어방안을 제시하였다.

With the recent increase in the volume of liquid cargo transportation, there is a need for STS( Ship To Ship) globally. In the case of the STS mooring, the safety assessment should be conducted according to other criteria because mooring is different from the general mooring at the quay, but there is no separate standard in Korea. Thus in this study, STS mooring simulation and sensitivity analysis using OPTIMOOR program, the numerical analysis program, was conducted to identify the characteristics of the STS mooring. The target sea modeled the Yeosu port anchorage in Korea and the target ship was selected as the case of VLCC (Very Large Crude Oil Carrier)-VLCC. Through the numerical simulation and sensitivity analysis, the characteristics of STS mooring were identified. Also based on these results, we focused on establishing the standard for STS mooring safety assessment. Numerical simulation results show that the STS mooring safety can be changed according to a ship's cargo loading condition, pre-tension of mooring line, sea depth, encounter angle with the weather, and the weather condition. Additionally, the risk matrix is prepared to establish the safe external force range in the corresponding sea area. This result can be used to understand the mooring characteristics of STS and contribute to the revision of mooring safety assessment criteria.

It is well known that simulation study in the preliminary design stage of harbors or berths is of great use, since it can provide helpful informations to the designer from the view point of ship navigations. In this paper, a brief review is made in the safety assessment of ship navigation for a 320,000 DWT VLCC entering Yecocheon harbor area, which is carried out by shiphandling simulator system. The geographic data base for the harbor as well as the mathematical models of the ship and environmental effects are designed and developed. Based in the on-site inspections and interviews with pilots in Yeocheon area, basic maneuvering plans and consistence with real operation conditions. Berthing and deberthing maneuvering simulations as well as approaching and departing simulations are carried out by 3 experienced navigators according to the maneuvering plans and environmental scenarios. The simulation results are analysed in various ways to evaluate the quantitative and qualitative maneuvering difficulties and thereby to assess the safety of ship navigation in that area.

As the faithful performance of ISPS of IMO, nowadays actually applicable an integrated safety and security system in and out of vessel should be organized in views of seafarers. Therefore, this paper is aimed to design a fundamental system for ship's integrated safety and security. The system of integrated grabbing will affect efficiently in any maritime field of material and human flow. Therefore this research will be expected to affect economical side by securing all the risk of maritime issues. In addition to the passenger ship and merchant vessel, it is applicable to other public and private vessels either. As a result of this paper, the system designed collecting various data through integrating the system including RFID reader, PIR sensor, and CMOS camera by putting an individual number into each unit that could be control at easy.

The Korean government has introduced and enforced maritime traffic safety assessment to secure traffic safety since 2010. The maritime traffic safety assessment is needed by law to design a new port or modify an existing one. According to Korea Maritime Safety Act, in the assessment the propriety of marine traffic system consists of the safety of channel transit and berthing/unberthing maneuver, safety of mooring, and safety of marine traffic flow. The safety of channel transit and berthing/unberthing maneuver can be evaluated only by ship-handling simulation. The ship-handling simulation is carried out by sea pilots working with the port concerned. The vessel's proximity measure is an important factor to evaluate traffic safety. The proximity measure is composed of vessel's closest distance to channel boundary and probability of grounding/collision. What is more, the probability of grounding becomes important. According to central limit theorem, a sample has a normal distribution on condition that its size is more than 30. However, more than 30 simulation runs bring about the increase of assessment period and difficulty of employing sea pilots. Therefore this paper is to find out minimum sample size for evaluating vessel's proximity. First sample sets of size of 3, 5, 7, 9 etc. are selected randomly on the basis of normal distribution. And then KS test for goodness of fit and t-test for confidence interval are applied to each sample set. Finally this paper decides the minimum sample size. As a result this paper suggests the minimum sample size of 5, that is, the simulation of more than five times.

This paper aims to investigated the reasonable objectiveness of trading areas on the Korea Ship Safety Act and to make a regulated proposal of trading areas. To achieve the above mentioned object, we analyzed the existing rules and other related circumstances of maritime fields. On the basis of this viewpoint, this paper was focused on three topics of concern : (1) the relationship between the ship Safety Act and other Maritime Acts. (2) the legislative examples of foreign countries, (3) the reasonable revised reasons of trading areas. In this paper, we proposed following four matters such as (1) the modification of ship's length and speed which are the designative basis of trading areas, (2) the extension of the smooth sea area to limit of territorial seas (3) the extension of the near-coastal area to the coasts of the P.R.C., Japan, the U.S.S.R and the R.O.C ., and rename of its area into the near & greater coastal area, (4) the annulment of greater-coastal area.

As a ritual of modern people is getting higher, the safety assessment of the structure related to people has become the most important part in the process of the design. Especially, in the case of a ship, as regulations about the safety of passengers and the pollution in the ocean are strictly reinforcing, the safety assessment has become the most important part in the process of the design. However, because the established safety assessment is mostly depend on the experienced theory, it is so difficult to assess the safety considering a lot of situations such as various ocean environments, the mistake of sailors and emergency situations. As the way to solve this problem, lately the study of the simulation using a computer has been processed. In this paper, we suggested network-based simulation system framework using HLA (High Level Architecture) among many kind of simulations to assess the safety of the ship. Because HLA has already become a standard of the future simulation system in the U.S. DoD(Department of Defense) and Korea army, we expect to raise the possibility in the future. In addition, because HLA makes a standard of documents and a reused component(Federate) of simulation(Federation) by OMT(Object Model Template) and RTI(Runtime Infrastructure), we expect that this study will be developing the safety assessment of ship as well as operation in warship and cooperation with another applications.
