Abstract
Wave energy is regarded as one of the most consistent and potent renewable sources due to its high energy density. The global reliance on conventional energy systems—such as coal, fossil fuels, and nuclear power—has led to an urgent need for cleaner and more sustainable alternatives. Among these, ocean wave energy presents a promising green solution. This study investigates the wave energy potential off the coast of Brass (longitude 515.130′E, latitude 518.890′N) using ten years (2014–2023) of oceanographic data, including significant wave height (Hs), peak wave period (Tm), and wave direction. Results show that Hs varies from 0 to 5 meters, with an annual average of 1.67 meters, peaking in July through September. Tm ranges between 13.14 and 20.03 seconds, averaging 18.28 seconds annually, with its highest and lowest values in August and December, respectively. The statistical probability of occurrence for Hs and Tm are 53% and 64%. Predominant wave directions fall within 206° to 209°, aligned SSW. Wave power ranges from 7.63 to 56.51 kW/m, with an annual mean of 31.42 kW/m. Seasonally, energy levels are highest in summer (47.41 kW/m) and autumn (38.02 kW/m) and lowest in winter (12.85 kW/m). The total annual wave energy with a 93.6% chance of Hs ≥ 1.5 m is estimated at 1712.1 MWh/m.
