Abstract: A method is provided of stopping an operation of a floating wind turbine, the wind turbine including a floating body, a tower mounted to the floating body, a nacelle mounted to the tower, a rotating hub rotatable mounted to the nacelle and having a plurality of blades, and a generator connected to the hub for generating electric power. The method includes: receiving a stop request for stopping the operation of a floating wind turbine; determining whether or not the stop request is non-critical to allow a delay or attenuation of stopping the operation of the floating wind turbine; and delaying or attenuating the stopping of the operation of the floating wind turbine, when the delay of stopping the operation of the floating wind turbine is allowed, so as to attenuate a wind turbine pitch movement.

Abstract: Renewable Energy (RE) sources are already one of the cheapest sources of energy available today but are variable and infirm, and the open ocean offers many opportunities to generate energy by using various disparate sources and methods on a floating station. These energy stations converting renewable energy including solar, ocean currents, wind, waves and batteries and hydrogen to store energy and provide sufficient stable power and energy as required and available most of the hours. The invention claimed here is a system to capture energy from a combination of wind, solar and ocean currents, along with batteries for storage and later use and hydrogen creation, storage and use for generation. In addition, apparatus is described that provide mechanical stability and resilience in deep open seas and reliably survive storms and hurricanes. Also described is a method for overcoming intermittency of ensuring continuous and stable energy export from the station, and finally methods to continually operate RE station in the open seas even during storms and hurricanes and survive the high winds and waves.

Abstract: A power generation system includes a flotation assembly configured to float in water and a first harnessing assembly coupled to the flotation assembly and disposed in an airflow above the water. The first harnessing assembly is configured to harness the airflow to create a first rotational energy. The system also includes a second harnessing assembly coupled to the flotation assembly and disposed in the water. The second rotational assembly is configured to harness movement of the water to create a second rotational energy. The flotation assembly also includes a generating module to convert the first and second rotational energies into electrical energy.

Abstract: An energy converter is provided for converting an energy of ocean waves received at the energy converter into corresponding electrical energy. The energy converter includes a buoyant platform having a peripheral edge region. One or more wave energy conversion devices are mounted around at least a portion of the peripheral edge region. The buoyant platform together with its one or more wave energy conversion devices are configured to exhibit at least one of a roll movement and a pitch movement when in use. Herein, natural resonant frequencies of at least one of the movements are matchable to a frequency of the ocean waves received at the energy converter and the one or more wave energy conversion devices are configured to convert the energy of the ocean waves into air movements to drive a generator arrangement to generate electrical energy.
