Definitions

  • This invention relates generally to use of renewable energy to provide power on offshore oil and gas facilities, and specifically to the use of low-head hydro-air turbines to produce said power from wave-induced air pressure.
  • Offshore oil and gas platforms have tremendous electrical power needs.
  • the electrical loads on fixed and floating offshore facilities are typically supplied by fossil fuel-driven power generating equipment (e.g., diesel generators). Smaller loads, less than about 50 kW, are often supplied by small-scale renewable energy generators such as solar panels or micro-wind turbines. Examples of facilities having such power requirements are fixed platforms having legs extending to the sea floor, floating platforms that are typically secured to the sea floor with lines, and floating production storage and offloading (FPSO) vessels.
  • FPSO floating production storage and offloading
  • the present invention is directed to methods, systems, and assemblies that use wave energy to drive one or more air turbines associated an offshore hydrocarbon facility, wherein such turbines can generate electrical power for use on the offshore facility and/or nearby exploration and production (E&P) facilities and equipment.
  • E&P exploration and production
  • the present invention is directed to one or more methods for harnessing or otherwise capturing wave energy for use on an offshore oil and/or gas platform, the methods comprising the steps of: (1) incorporating an oscillating water column into an offshore oil and/or gas platform, wherein water, driven by wave energy, enters and leaves from an inlet/outlet port that is integrated into the platform's structure, and wherein the inward/outward flow of water raises and lowers the water level in the oscillating water column, thereby effecting pressure changes in the air residing above the water in said column; (2) utilizing the pressure changes in the air above the oscillating water column to drive a hydro-air turbine (e.g., Wells-type turbine) that is coupled with an electric power-generating device (e.g., a rotating alternator) so as to generate electric power; and (3) using (e.g., via a power take-off cable) the electric power to power devices on or near the offshore oil/gas platform.
