Design and Analysis of Watertight Bolted Pressure Chamber
Author:
Abstract: Water tightness is one of the challenges in design of submerged vessels. In this paper, a pressure proof test chamber is designed in order to test water tightness of a hatch and also for testing water prove of hull penetrators which used in submerged vessels for crossing sensor cables through the pressure hull. The test chamber is designed such that its interior simulates the wet environment (surrounding water environment) and its exterior simulates the watertight proof environment (the dry environment). This test chamber is designed to withstand internal pressure up to 20 bar; i.e. 200 meter submerge. First a three-Dimensional model of the test chamber is made using AUTODESK INVENTOR and then stress analysis is carried out using ANSYS solver provided in AUTODESK INVENTOR. Contact analysis between the pressure chamber and the assembly hatch is also carried out to examine the gap between contact surfaces of bolted region of the test chamber. Chamber shell and heads thicknesses calculated according to ASME code section-VIII Div.2 and verified through the finite element analysis. The analysis shows the ability of the test chamber to withstand the applied pressure and the effectiveness of the bolted assembly hatch.
