The Paradip port, India is a natural deep-water port, located in the Jagatsinghpur district of Odisha, on the East Coast, in terms of latitude and longitude its location is 20°-15′-55.44′’ N and 20°-40′-27.34′’ has experienced an extreme wave oscillations 3.0 to 5.0 m during its extreme weather conditions. In this study, numerical investigations are carried out to examine the frequency distribution of standing waves across the oceanic surface in Paradip port at four synthetic record stations in the presence of the partially reflecting harbor wall. The numerical scheme's accuracy is determined through the simulation results and by comparing with the measurement data at Pohang New Harbor (PNH), South Korea. At four synthetic record stations, the wave analysis with a different reflecting coefficient of harbor wall through spectral density is determined when the normal incident wave propagates towards the Paradip port corresponding to the wave period. The distribution of wave energy through resonance frequencies is estimated in the Paradip port to identify the safe locations for cargo handling.
