This study presents the hydrodynamic analysis of an array of oscillating water column (OWC) devices gliding freely in limited profundity waters and presented to the activity of standard surface waves. The hydrodynamic analysis comparison was made using computational fluid dynamics (CFD) analysis. The advantage of the CFD being an extremely encouraging instrument an originator can be utilized to explore and survey gadget survivability under various conditions and in sporadic waves after further approvals. This method provides an efficient tool for complete hydrodynamic analysis of these devices. The pressure hydrodynamic parameters were calculated using the characteristics of the waves in the Arabian Gulf area with an average historical wave height of 1m. The OWC chamber used for the breakwater experiments was used by Morris-Thomas et al. , whereas for the offshore OWC, the inner diameter was used, which achieved the same cross sectional area as the breakwater chamber. After performing modeling and analysis, the output flow obtained rendered the conclusions for the hydrodynamic performance of the breakwater chamber. A higher OWC devices efficiency was achieved compared to the open ocean fixed OWC, and a variation in efficiency was observed with the change in wave steepness.
