Due to COVID 19, the global economy is facing a crisis situation, and in the export-oriented industry, companies must consider survival. The government and industry are striving to revitalize exports in a number of ways, and with restrictions on non-face-to-face export activities, they are contemplating various ways to implement non-face-to-face export marketing. Among them, various studies are being conducted in various industries on the part of conducting an online exhibition. In particular, the shipbuilding and offshore industry is a major export industry, and offline exhibitions held around the world were an important opportunity for marketing, and the use of online exhibitions to substitute for them is urgently needed. In this study, we study AR, VR, MR, etc., which are various element technologies necessary for building an online exhibition hall suitable for the shipbuilding and marine industry, and how they are applied to online exhibitions.

This study analyzes the results of applying the ISO19030 (hull and propeller performance monitoring method) standard to an actual 178 k bulk vessel. Recently, there have been many attempts to apply various energy reduction solutions to vessels to continuously strengthen GHG reduction regulations and secure maritime competitiveness. However, it is not easy to quantitatively analyze the performance of a ship. To resolve these problems, shipping companies, marine paint companies, ship owners, and transportation associations have appointed specialists and standardized the ISO19030 (standard of hull and propeller performance monitoring method) guidelines in 2016 after three years of continuous review. The ISO19030 standard provides methods to monitor hull and propeller performance quantitatively through standardized procedures, thus allowing ship managers to arrive at informed decisions for hull and propeller maintenance, and to evaluate energy-saving solutions and ship-maintenance efficiency. The ISO19030 standard provides a method of analyzing the ship's own performance by collecting the ship's operation and agency data and correcting its environmental and operating factors. In this paper, we apply the ISO19030 standard to three actual ships and propose the ISO19030 application result and the improvement point of the current ISO19030 standard.

Recently, production cost of ready mixed concrete has been increased due to the rising cost of raw materials such as cement and aggregate etc. cause by the upturn of oil price and increase of shipping charge. The delivery cost of ready mixed concrete companies, however, has been decreased owing to their excessive competition in sale. Consequently, ready mixed concrete companies began to manufacture the concrete by mixing ground granulated blast furnace slag(GGBF) and fly-ash in order to lower the production cost. Therefore, the objective of this study was to predict 28 days strength of GGBF slag concrete by early strength(warm and hot water curing method) for the sake of managing with ease the quality of ready mixed concrete. In experimental results, the prediction equation for 28 days compressive strength of GGBF slag concrete could be produced through the linear regression analysis of early strength and 28 days strength. In order to acquire the reliability, all mixture were repeated as 3 times and each mixture order was carried out by random sampling. The prediction equation for 28 days strength of GGBF slag concrete by 1 day compressive strength(accelerated testing) according to warm and hot water curing method won the good reliability.

In recent years, the transportation sector has been undergoing very rapid and multifarious changes due to the M&A, alliances between shipping companies, introduction of larger container ship as it cost reduction measure and the application of integrated logistics to satisfy the needs of customers. Therefore, container terminal is required adequate terminal facilities, sufficient channel depth, efficient handling and low cost of port fees and dues. The purpose of this paper is for functional assessment of efficient container terminal. Firstly, the container operating process information about yard equipment and chassis is extracted through the analysis of practical daily work report of container terminal. Also, the formulae of skill factor and troubles of operator on transfer crane are defined. Lastly, container handling simulation model which consideration of skill factor and trouble of operator is proposed by Petri network model.

This study investigates cargo management issues in the shipbuilding and marine equipment industry. Problems are analyzed concerning the absence of information about exact cargo location and condition, damage, loss, replacement, and transportation delays during the import and export process. Then, improvements are proposed to solve these problems. To illustrate, real time information about the status and location of cargo should be communicated between import/export and logistics companies to facilitate material logistics for shipbuilding & marine equipment. In addition, a standard cargo classification and recognition system should be established to reduce delivery delays and mistakes, so then enhancing logistical efficiency. Moreover, it is also necessary to nurture professional shipbuilding & marine equipment forwarders to strengthen their expertise with professional education and training.

The variation of marine accidents and ship's insurances is to be the measurement of assessment concerned effect of importing ISM Code because each kind of ship accident's expenses and compensation for the loss have an effect on the ship's insurance and P&I insurance. Therefore in this study, we had grasped the accomplishment of importing ISM Code, using analysis of the variation of marine accidents and ship's insurances in domestic shipping companies from one year ago to 8 years after importing ISM Code. As the result of analysis, compared with the period of a year before carrying out ISM Code, marine accidents were showed a decrease of about 14.4% at 8th year of importing ISM Code. Also, the insurance had tended downward every year.

Maritime security incidents by pirates and by terrorists increase, but maritime incidents investigation models are limited to figure out the maritime security incidents. This paper provides the analysis model for maritime security incidents. To develop this analysis model, this categorizes five threat factors, the ship, the cargo type, port system, human factor, information flow system, makes the risk assessment matrix to quantify the risk related to threat factors and classifies four priority categories of risk assessment matrix. Also, this model makes from the frameworks which include a variety of security initiatives implementing in stakeholder levels like international organizations, individual governments, shipping companies, and the ship. Therefore, this paper develops the Analysis for Maritime Security Management model based on various security initiatives responding to the stakeholder levels of maritime security management and top-bottom/bottom-up decision trees, and shows the validity through verifying the real maritime security incident of M/V Petro Ranger.

In North-East Asia, Port traffic in Asia-North America sea route has been rapidly increasing due to economic growth in China and ASEAN. Furthermore, the major shipping companies directly call at northern chinese ports like Qingdao, Dalian and Tianjin without passing through Korean ports on Asia-North America sea route. To acquire a port traffic and develop a hub port, governments in North-East Asia have intensively invested in the development of port. Therefore, Busan new port and Gwangyang port have been developed in Korea. According to the medium-long term development planning, the port should give a enormous budget investment for the port facilities construction. So the inaccurate estimation may lead to the unreasonable port development policy. Firstly, based on the estimation of Chiang Bong-Gyu & Yang Hang Jin(2005), this study gave a comparison with the estimation of Ministry of Maritime Affairs and Fisheries(2001) and OSC/Glori(2005). Secondly, taking into account the influence factors for port traffic, this study made an estimation of port traffic for Busan new port. On the basis of this estimation, this study is compared with the estimation of Ministry of Maritime Affairs and Fisheries(2001) and OSC/Glori(2005). In conclusion, in case of the development of Busan new port, based on the estimation of Ministry of Maritime Affairs and Fisheries(2001), this study should the high possibility that the Busan new port will be serious lack of the port facilities in the year of 2011. And according to the OSC/Glori(2005)'s estimation result, there is a lack of the port facilities, though we have modified the port investment plan.
