Floating vessel and method of operating a floating vessel

A floating vessel comprising:

• a gas turbine engine-generator assembly comprising a dual fuel gas turbine engine operable on both boil-off gas from an LNG reservoir and on marine gas oil, wherein the gas turbine engine-generator assembly is configured to generate a first electrical power and to supply the first electrical power to an electrical distribution system, a maximum of the first electrical power being between 10 MW and 18 MW;
• a steam turbine engine-generator assembly configured to generate a second electrical power and to supply the second electrical power to the electrical distribution system, wherein a portion of depleted steam from the steam turbine engine-generator assembly is channeled to one or more steam loads aboard the floating vessel;
• a steam generator configured to receive hot gas exhausted from the gas turbine engine-generator assembly and hot gas exhausted from an oxidizing unit to generate steam, wherein the steam is configured to drive a steam turbine of the steam turbine engine-generator assembly;
• and
• a propulsion system configured to propel the floating vessel using a propulsion power supplied from the electrical distribution system,
• wherein the gas turbine engine-generator assembly further comprises a first exhaust duct in fluid communication with a crossover duct to channel the hot gas exhausted from the gas turbine engine-generator assembly to the steam generator, the exhaust duct including a first diverter valve to modulate an amount of the hot gas exhausted from the gas turbine engine-generator assembly that is fed to the steam generator.
