This study investigates the hydrodynamic behaviour of submerged offshore vehicles, including submarine hull and NACA aerofoils through simulation and fluid flow analysis, using ANSYS Fluent. The study models the interaction between fluid flow and offshore submerged vessels i.e. a Standard Submarine Model and various NACA profiles, simulating pressure distributions and drag forces that affect offshore operational stability. The analysis comprises of the study of multiple mesh profiles required to calculate the drag force and their coefficients in a pressure based solver. The inter-dependency on the variation of one data on the other is also studied with the help of tables and graphs. The error analysis between the data obtained is also investigated in order to ensure the validity of the report. The findings contribute to the optimization of offshore structures, aiding in the design of submerged energy platforms and deep-sea exploration vessels. Concurrence with the data obtained is generally agreed as accepted within the error margin of 10% which is quite within the range.
