Abstract

This study analyses the wind speed characteristics in the Kilwa offshore zone, situated along Tanzania's southern coast. The Rayleigh probability distribution model, which only has one parameter the scale parameter was used for analysing the wind speed characteristics since it is simpler to estimate and work with. In order to match the hub heights used in modern offshore wind turbines, wind speeds were initial measured at a height of 10 meters and then projected to higher heights of 50 and 70 meters using standard wind profile equations. Analysis of monthly and annual wind speed distributions revealed that average wind speeds ranged from 9 to 10 m/s. They show a high potential for energy generation because they are within the ideal operating range for modern offshore wind turbines. The region's feasibility for the utilization of sustainable offshore wind energy is further demonstrated by the consistent and advantageous wind conditions that are seen throughout the year. The study highlights Kilwa's potential for offshore wind farm development, which serves the broader goal of generating sustainable offshore wind energy solutions and enhancing energy sources. The study not only identifies Kilwa as a potential location for offshore wind generation but also establishes a foundation for more comprehensive feasibility and investment analyses in the future.
