Floating power generation system

A system for safely using natural gas to generate electricity for an electricity consumer comprising:

• an offshore gas process vessel that includes a process hull that is moored at a first location to the sea floor, hydrocarbon gas processing equipment on said process hull, and transfer facilities constructed to transfer liquified hydrocarbon gas between the process hull and a tanker that carries at least 10,000 tons of liquified gas;
• a generator vessel that includes a generator hull that is moored at a second location to the sea floor, and an electricity generator unit that uses natural gas as fuel to generate electric power;
• an electric cable that carries electricity from said generator unit to said gas processing equipment on said gas process vessel;
• said generator vessel lying at least 0.2 kilometer from said process vessel, to provide safety to personnel.

A method for using gaseous hydrocarbons as a fuel to provide electricity to an onshore distribution facility for delivery to electricity consumers such as factories, offices, and residences, in a manner that isolates the consumer from any dangers arising in the handling of such gaseous hydrocarbons, comprising:

• anchoring to a sea floor, a first floating structure that lies in a sea and that carries a gas-fueled electricity generating unit;
• establishing an underwater electricity-carrying power line in extension between said first floating structure and said onshore distribution facility;
• supplying said gaseous hydrocarbons to said first floating structure;
• flowing said gaseous hydrocarbons to said generating unit to generate electricity, and passing said generated electricity along said power line to said onshore distribution facility.
