This study have goal with conceptual design for offshore structures of high pressure drop control valve for localization valve for development accomplished with flow analysis based on provision of ANSI B16.34, ANSI B16.10, ANSI B16.25 In order to localize the Offshore structures high pressure drop control valve. This study is numerical analysis for zambil offshore project of high pressure drop control valve. The solver which ANSYS workbench used for offshore structures analysis. The working fluids assumed the glycerin(C3H8O3). The structural analysis used ANSYS which is a commercial code. Stress analysis result of internal pressure in valve showed lower than yield strength. This is expect to need more detail design and verification for stem and disk structure.

In this study, the design of high efficiency exhausted injector system. The result shows that existing injector system has problem with fume collector system. Model-3 shows difference and high flow rate as meaning of suction capability. Finally, the improved high efficiency exhausted injector was designed.

In this study, the development of collector system for high efficiency exhausted. The aim of this study is to remove crack on a ventilation device at the suction part of plants factory, and the main point is making optimum configuration by improving an existing collector system Finally, the improved high efficiency exhausted was designed.

In this study, ER fluids were working fluid and yield shear stress of attained dispersive ER fluids made by analyzed to adapt effectively at the practical equipment like three port ER valve. In addition, movement of ER particle was observed by using a microscope the same as the strength of electric field with Bingham characteristic. Basis material was presented to develop 3 port ER-Valve by quantitatively comparing and analyzing entrance, load and outlet flows differences of 3 port rectangular tubes. This study, after designing and producing the 3port ER-Valve, considered the characteristic of pressure drop, outlet and load flow rate by changing the strength of electric field on ER fluids flowing between electrodes.

This paper presents an efficient modeling method for Multi-nozzle system. Using effective elements to take for coating yarm. At that time, if is very important not only precision coating yarm machine and machining technique but also CAE technique. The proposed multi-nozzle for coating yarm model is more precise.
