Because of emission control of greenhouse gas, shipbuilders, especially those in Korea, are pushing forward to introduce eco-friendly ship-building technology utilizing LNG. However, Technical skills of domestic shipbuilders in manufacturing the cryogenic pump designed to supply LNG for vessels are so low that technical skills for design and manufacturing of core parts are in urgent need. Therefore, This study described about the Rotor as a core part of cryogenic submerged centrifugal pump for ship LNG supply system. We wish to utilize for the basic data to develop the technology for the Rotor as deducing the optimal outcome with the experimental and the analytical methods in material selection.

In the KIOST MOERI model ice basin, a lot of experiments to find the material properties of model ice and model ship tests are being performed. And therefore many data information was produced, yet it was saved as excel data format. In order to manage and use the data more effectively and systematically, a proper database management is required. To make realistic engineering DBMS(database management system), understanding of test process, the usage of data, design of data schema and computer language and system management are required. In this paper, basic design process and usage of DBMS based on network and multiple user concept is introduced.
