  • 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.
