ANSYS Finite Element Analysis:

 FEA Summary of Pressure Vessel:

 The FEA study simulated hydrostatic pressure at 350m depth, with seawater density of 1023.6 kg/m³ and gravity -9.81 m/s² in the z-direction. The free surface was set at the vessel’s highest point, with x and y displacements fixed at 0m and a 5m displacement in z-direction to reflect operational constraints.

 Mesh Quality:

 The mesh showed good element distribution, with some lower-quality areas still within acceptable limits for accuracy.

Structural Analysis:

 The maximum von Mises stress was 88.92 MPa, with stress concentrations along axial and hoop regions, aligning with expectations.

Safety Factor:

 The minimum Factor of Safety (FOS) was 2.81, ensuring compliance with standards. The vessel is structurally sound and reliable for 350m depth operations.
