Design and Analysis of a Hyperbaric Chamber

Hyperbaric is defined as an act of operating at pressure higher than atmospheric pressure. The hyperbaric chamber is an improvised version of pressure vessel where a pressure vessel is designed in a way that the vessel can be excess via door, in order for a components to be inserted and tested at high pressure. The high pressure acted in the vessel can be maneuvered or controlled by a fluid that is pumped to the vessel. The main purpose of designing this hyperbaric chamber is to support the UTP Deep-water Research for testing a deep-water Oil and Gas instrument at high pressure. Hence, the aim of this project is to design and analyze the Hyperbaric Chamber according to the pressure vessel design guideline drawn by ASME VIII standards with the defined parameter taken by previous researcher in deep-water oil and gas field.
There are four major parts designed in this hyperbaric chamber which are the vessel main body, vessel heads, nozzle instrumentation attached to the vessel and the vessel supports. The designed simulation is carried out by two mechanical engineering software which is CATIA V5R and ANSYS 14. CATIA V5R is used to drawn the virtual designed of hyperbaric chamber and then it is transferred to ANSYS for further analysis. Based on ANSYS simulation results, there are 7 critical stress points defined in the designed hyperbaric chamber. Compared with the theoretical stress calculated to the results analyzed by ANSYS, proved that the stress acted in the hyperbaric chamber wall does not failed due to over pressure at operating condition. Hence, the design is acceptable as per required design specification.
