Offshore electrical power plant

A floating vessel equipped with a power plant and comprising a hull and a process deck arranged on a portion of the hull above one or more compartments within the hull,

• the power plant comprising a fuel source, and at least one electrical power generator driven by a gas turbine;
• the fuel source arranged for providing fuel to the gas turbine of the at least one power generator, wherein
• the fuel source is a fuel gas source comprising at least one LNG storage tank for storing LNG and a regasification unit coupled to the at least one LNG storage tank for producing a stream of regasified natural gas from stored LNG,
• and
• per one or more gas turbines, the floating vessel is equipped with at least one steam production unit coupled to an exhaust of the one or more gas turbines for receiving heat to produce pressurized steam;
• per each steam production unit, the floating vessel is equipped with at least one secondary power generator driven by a steam turbine, which is coupled to the respective steam production unit for receiving produced steam;
• each gas turbine of the one or more gas turbines and the at least one steam production unit are positioned on or above the process deck, and
• each of the respective secondary power generator and the steam turbine are positioned under the process deck in the one or more compartments, and
• wherein the floating vessel is a converted LNG carrier having a number of the LNG storage tanks originally installed for storage of the fuel gas, in which a portion of the number of originally installed LNG storage tanks is removed at positions within the location of the process deck.
