  • A production management system is developed to enhance both the information and productivity of ship and offshore plant deckhouse floor outfitting. The functions of the production management system for the deckhouse floor outfitting were reviewed based on a literature survey of several production management systems with respect to the ship building and architecture fields. This study investigated numerous daily production reports and their application to actual work places to utilize the system development. The developed scanned drawing-based production management (SDPM) system minimizes any loss and/or distortion of work information between the workshop and management office when applying a scanned production drawing to the daily report. The SDPM system increases the data objectivity, as well as intuitiveness of the information generation by adopting an efficient user interface, which makes it possible to perform image annotations on the scanned drawing for the daily production report while simultaneously interacting with the production management database. Applying the system operation to actual deckhouse floor covering work verified that it was feasible to use the SDPM system for production management in the ship outfitting work process.

  • Great number of ships has been built by Korean Shipyards since early of 2,000 due to the expanding worldwide trade. Most of shipyards have enlarged the weight of erection block and many blocks have been assembled in block fabrication factories outside the shipyards to reduce the shipbuilding period. Especially, Giga blocks that exceed 2,000 tons are often assembled by the block fabrication factories outside the shipyard. Generally, the blocks are transported to building dock in shipyard by towing barges. Accident can be occurred during the sea transportation and it may bring about not only the delay of delivery but also a disaster on the ocean environments. Transportation condition of GPE (Grand Pre-Erection) block differs from the ocean going conditions of marine vessels. Special consideration should be included before transportation work in order to guarantee the safety of GPE blocks and barge carriers. In this paper, several examples, which have been investigated to set up the safety standard of transportation of the GPE blocks on coastal routes, are introduced. For the barge transportation on coastal sea route, the design criteria are discussed, considering the design wave, the acceleration induced by wave, structural strength, and the fixture condition of blocks.

  • This study conducted a conformity review of Korean shipping industry policy and suggested that the Korean five-year shipping reconstruction policy has not violated the WTO (World Trade Organization) trade law agreement yet. In order to investigate the latest Korean shipping policy, domestic and foreign reports were reviewed, and after that, the WTO's published data and domestic and foreign journals were analyzed. Through this process, this study tried to review the conformity of trade laws by major Korean shipping policies. The shipping industry is a representative service industry, and subsidies for this are not subject to WTO-level regulation in principle. The purpose of Korean shipping industry policy is to support the shipping industry, a type of service industry, and even if the ship-building and manufacturing industries (shipper) indirectly spread benefits in the process, this is unintentional or private-level support. That is, this study concluded that It is understood that Korea's five-year shipping reconstruction policy does not violate the WTO trade law agreement.

  • Whereas shipping and Ship-building industries of Korea have been under the direct influence of International Maritime Organization (IMO) conventions and resolutions that aim at maritime safety and the protection of marine environment, it is needed that a specialized institute for dealing with IMO Agenda be established by industry-academy-government collaboration. Accordingly, this study proposes the establishment of a specialized institute to manage the IMO Agenda. To this end, integrating the existing bodies and their functions into a specialized institute, namely, the International Maritime Cooperation Center, is suggested. This center, composed of 40 researchers and operated by the Korea Maritime Institute, could assume this role. This study proceeds by building an estimate of the operational cost of the institute and exploring practical ways to finance it through the private and public sectors, also considering revisions to the Maritime Safety Act to ensure continuous operation of the new institute.

  • The cruiser trip which can have various experiences in a short time is growing as the best tourism package because there is less leisure time in contrast of the increased income in 21C. in other words, as the demand of the tourist goes up, the number of ships built newly is increasing. The order of the ship keeping first and second rank in Korea has arranged a long-term strategy in order to get into the global market with the cruiser with the high value added. They also set the objective related to the cruiser design and skillful construction work. We need to observe the change and trend of the cruiser with a care at this time when the cruiser industry is launched out. In this study, the cruiser industry is divided by four periods: the spring time, the depressed time, the developing time and the peak time, on the basis of the trend of the development and the change of space structure. In addition, it was analyzed in this study that there were the various trends such as the ratio, the structure and the type of the space as well as the interior plan in the passenger's residential place The aim of this study is to present the fundamental material about the interior plan to prepare for building the domestic cruisers in a foreseeable future.

  • The high grade thick plate is in great demand in the ship building industry and the construction industry. The main problems to produce the high grade plate are residual stress and flatness of plate. In the previous research, Finite Element Analysis(FEA) was conducted for cold roller leveler to understand the behaviors of cold roller leveler under different conditions of thickness, intermesh, and yield stress. In this study, a numerical model of roller leveler is developed and the calculated results of this model are compared with the FEA results to show the validity of the numerical model. The optimal leveling conditions to improve flatness of plate are suggested using this numerical model.

  • A fact that limits a company's ability to achieve more of its goal is referred to as a 'constraint' shipbuilding industries need to identify and manage constraints. The theory of constraints is evolved out of the problems of bottleneck formation. This happens and is conserved for the formulation if various real time problems for arriving standard uniquely addressed problems If, for example, the goal of a shipbuilding industry is to make money now and in the future, it is suggested that TOC will enable th mangers of the company to do so. TOC, focuses the organization scare resources on improving the performance of the true constraints, and therefore the bottom line of the organization. An attempt is made for the implantation of the theory into real world shipyard decision support mechanism.

  • This study has investigated shipping finance systems in Korea and China, and extracted negative factors based on it to propose a way to develop the shipping financial system in Korea for shipbuilding industry and marine transportation. From after the global financial crisis in 2008 to right before the Lehman Brothers Holdings bankruptcy, shipping finance has been dominated by the major industrialized countries in Europe. However, the weight point is moving to the countries in Asia region such as Korea, Japan, and China based on relatively strong banking system and low interests rate. This study focused on the alternatives the current situation that the starter of shipping finance among three countries in Northeast Asia, South Korea is facing China's challenges. In the paper, shipping finance in Korea presented its defectives such as the limits of ship financing, lack of professional workforces, ever-present foreign exchange risks, and lack of understandings of the parties. As the countermeasures of them, it proposed establishing professional institute for ship financing, training professionals in financial industry, raising foreign credentials of won, and continuing associations between the parties. Even though we are the first Asian country introduced ship funds, the ship funds growth in China shall be under our eyes while we keep systemic networks between shipping, ship building, and ship financing.

  • The living performances of crews and passengers in cabins have been less received attention, while Korea is a top leading country in ship building industry. To develop a high value added ships like 5-star cruisers, researches on the comfort and productivity in cabins should be carried out with urgent. The purpose of this study is to measure and analyze of the ship's indoor thermal conditions in spring, summer and winter, and also to compare the seasonal differences, of which conditions are supplied from and controlled by marine HVAC The temperature, humidity and air supply volume of 5 different needs of cabins on a training ship were measured through a year, which was launched at Dec. 2005 and totally 246 crews can go on board for education. The following results were obtained: (1)In the spring, the temperature in cabins was measured as $20{\sim}25^{\circ}C$ and humidity was below 30%. (2)In the summer, the temperatures was controlled at $21{\sim}27^{\circ}C$ in almost cabins and humidity was between $40{\sim}60%$ which is known as comfort conditions. (3)In the winter, temperature and humidity was maintained between $19{\sim}26^{\circ}C$, and humidity was between $10{\sim}50%$. (4)It is clear that the humidity conditions in cabins are not properly controlled at all through a year to satisfy the Comfort Standards provided by ASHRAE and/or ISO, In conclusion, humidification and dehumidification of cabins must be treated with importance for more comfort living and working environments for crews and passengers.

  • In the ship and offshore structure design, age-related problems such as corrosion damage, local denting, and fatigue damage are important factors to be considered in building a reliable structure as they have a significant influence on the residual structural capacity. In shipping, corrosion addition methods are widely adopted in structural design to prevent structural capacity degradation. The present study focuses on the historical trend of corrosion addition rules for ship structural design and investigates their effects on the ultimate strength performance such as hull girder and stiffened panel of double hull oil tankers. Three types of rules based on corrosion addition models, namely historic corrosion rules (pre-CSR), Common Structural Rules (CSR), and harmonised Common Structural Rules (CSR-H) are considered and compared with two other corrosion models namely UGS model, suggested by the Union of Greek Shipowners (UGS), and Time-Dependent Corrosion Wastage Model (TDCWM). To identify the general trend in the effects of corrosion damage on the ultimate longitudinal strength performance, the corrosion addition rules are applied to four representative sizes of double hull oil tankers namely Panamax, Aframax, Suezmax, and VLCC. The results are helpful in understanding the trend of corrosion additions for tanker structures.
