Abstract
India has one of the fastest growing economies in the world and has an increasing energy demand, which is expected to double in 2020 compared to the present demand. Wind energy has gained wide acceptance across the globe and presently the focus is toward development of offshore wind farms. The offshore wind farm technology faces a number of technical challenges due to the harsh installation and operation conditions. Foundations supporting offshore wind turbines/wind data collection platforms are subject to constant wave loads. Offshore work involves increased risks of strong winds which affect the amount of time available for installation and maintenance which in turn influence capital and operation costs. Hence, this work is focused on development and analysis of economic and safe installation methodology in high tidal and current environment. A monopile has been designed suitable for high tidal environment at Gulf of Khambhat and Gulf of Kutch, Gujarat. Monopile static analysis, pile–soil interaction studies, and free vibration analyses have been carried out using finite element method. Developed safe and economic installation methodology through detailed lowering analysis for monopile in regular and irregular wave conditions and recommended appropriate vessel with hydraulic gripper as attachment to restrict the lateral displacements.
