  • The application of all regulations during building phase, plus constant vigilance in operation is essential to reducing the risk of fire aboard. A Safety by design approach is increasingly important. Fire safety regulation can solve problems which are hard to be solved by HSC code(International Code of Safety for High Speed Craft). Recently HSC code is applied for ship design development or guidance to the designer and demonstrates many advantages. In this pages, ship fire Safety are realistically modeled as ship design and the shipboard fires & muster stations are analyzed using HSC Code.

  • The most important factor when designing coastal and offshore concrete structures is durability. However, concrete in marine environment is exposed to physical and chemical deterioration of seawater, which might easily lead to low quality. The purpose of the present study is to understand advantages of adding ground solidificaton materials by comparatively analyze the seawater resistance of general concrete and environmental-friendly ground solidification materials.

  • Sulfate anion which cause concrete degradation is affected on marine structures. There are two of control method concrete degradation which is arisen by sulfate anion. Cementitious materials prevent permeation of sulfate anion and water-binder ratio increase to improve watertightness. But, those methods are passive. So, this study is developing new materials which prevent actively concrete degradation on sulfate anion.

  • This study, as a pilot study to implement and extend the marine healing which has been rapidly extending oversea areas into the domestic market, has collected seven major marine healing resources such as ocean water, sand, salt, mud, seaweeds, forest, and weather targeting selected four pilot municipalities and established a GIS DB. Furthermore, web GIS based marine healing portal has been established to support the easier utilization of the GIS DB and various marine healing related contents, thereby facilitating expansion of related industry. The portal includes marine thematic maps as well as research papers, related therapy manuals, and various activities and programs of the pilot municipalities. It is expected that the portal would contribute to the expansion of the domestic marine healing industry significantly through the pilot operation of the portal, not to mention of the needs of subsequent studies for expansion of the marine GIS DB and securing more various contents.

  • The high tech marine transportation infrastructure is an innovative transportation infrastructure that may be able to secure a safe transportation environment as well as efficient operation by connecting up-to-date skills including a broad range of wire and wireless communication-based information, control and electronics technologies. When integrated into the marine transportation infrastructure by the standard requirements, these standard technologies help monitoring and managing navigational aids. This paper defined a concept of middleware in the marine traffic management systems which gives characteristics of system independency, scalability, extensibility, and researches a functionality of the middleware and a software block of the middleware.

  • Recently, the building has been changed into high-rise and long span and this yields a development of high performance structural steels in construction market. According to this effect, the SM 520 and the SM 570 were developed and utilized into steel building industry. However, the study for fire resistance of them were not done actively. In this study, to know and comparative the fire resistance performance of long span beams built up with high strength structural steels an analytical method is going to applied using mechanical and thermal properties at high temperature.

  • Recently, the supplying of basic materials for construction of building as sand is big issues due to lack of shoreside supply. For solving this problem, many suppliers attempt to gather aggregate from the sea bottom of the EEZ & west coastal area of Korea. In this regard, the 'Jangantoe' which exists in the westside of the Daesan port is worth noticing as good seasand supplying areas. The Chungnam Aggregate Association have plan to gather of seasand from 'Gaduckdo 5 regions & Igok 3 regions' which lies westside about 6 miles off from the Jangantoe areas. This designated area also locates upper parts of the Gadaeam TSS(Traffic Separation Scheme) which is very useful passing routes for the sailing vessels of Inchon & Daesan ports. In this study, the evaluation of the safety for passing vessels in the vicinity of the seasand gathering area was performed by various methods of radar observations & GICOMS AIS data for marine traffics and vessel traffic-flow simulation of the 'Marine Traffic Safety Diagnostic Scheme'. By the results of this evaluation, I suggested comprehensive countermeasures for the safety of passing vessels in the near the seasand gathering area.

  • Propulsion in waves is a complex physical process that involves interactions between a hull, a propeller, a shaft and a prime mover which is often a diesel engine. Among the relevant components, the diesel engine plays an important role in the overall system dynamics. Therefore, using a proper model for the diesel engine is essential to achieve the reasonable accuracy of the transient simulation of the entire system. In this paper, a simulation model of a propulsion system in waves is presented with emphasis on modeling a two-stroke marine diesel engine: the framework for building such a model and its mathematical descriptions. The models are validated against available measurement data, and a sensitivity analysis for the transient performance of the diesel engine is carried out. Finally, the results of the system simulations under various wave conditions are analyzed to understand the physical processes and compare the efficiency for different cases.

  • After Chinese reforms and market opening, China actively started working on ways to attach importance to the ocean and it's maritime strategy has been developed and carried out by external and internal factors. We can take two things as external factors attributed to China's marine strategy. The first one is maritime environment change in the East Asian region and the second one is the strategic importance of Taiwanese Straits and the South China Sea. And we can take about national strategy, security strategy, and change of foreign policy as internal factors. China recognizes the ocean as a major step to achieve a goal of national development. The main goal of China's marine strategy in the 21st century is to secure marine transportation and marine resources and to make peaceful maritime environment in the ocean to keep up with their economic development by opening itself to the world. China has strengthened their defense abilities to act against threat of national security by modernizing sea forces and increased national power by building up the marine power. It is expected that China will continue to seek more aggressive maritime strategy on matters of national security as well as pour heir efforts into making economic development and obtaining energy resources. This will also be one factor making new dynamics between countries in and around the East Asian region.

  • During the period of every summer to early autumn seasons, ships have been wrecked or grounded from effect of a typhoon in the water areas around Korean Peninsular. Typhoon Maemi. which brushed South Korea in September 12-13, 2003, left at least 110 dead or missing, knocking down building. smashing ships and triggering floods that forced about 25,000 to flee from their homes. In this work. records .of marine accidents caused by a typhoon are investigated for the period from 1962-2002. The distribution is also compared with the trajectories of typhoons, passed during the 1990-2003. In addition to that, attack frequency of typhoon and number of marine accidents is the highest in August
