The present invention relates to an arrangement structure of a floating storage gas power plant. The arrangement structure of a floating storage gas power plant is provided to store liquefied gas (LNG) in cargos of the floating storage gas power plant and produce electricity using the LNG, is capable of preventing explosion and minimizing the length of a hull by arranging a gas power generation unit and a waste heat recovery steam generator on the optimal position of the upper part of a hull deck, and improves the structural stability of the hull by lowering the center of gravity of the hull. The arrangement structure of a floating storage gas power plant comprises: a cargo system (1000) storing LNG in a floating structure (10), and loading and unloading the LNG; a fuel gas supply system (2000) installed on the floating structure (10) to evaporate the LNG of the cargo system (1000) into fuel gas; a gas turbine/engine power generation system (3000) including a gas power generation unit (3100) operated by fuel gas supplied from the fuel gas supply system (2000), and a first generator (3200) producing electricity by the gas power generation unit (3100); a waste heat recovery steam generator (HRSG) (4000) generating steam by the waste heat of exhaust gas generated from the gas power generation unit (3100); a steam turbine generation system (5000) including a steam turbine (5100) operated by steam supplied from the waste heat recovery steam generator (4000), and a second generator (5200) producing electricity by the steam turbine (5100). The waste heat steam generator (4000) and the gas turbine/engine generation system (3000) are collinearly arranged in the direction of the floating structure (10), while the gas turbine/engine system (3000) is arranged on the deck of the floating structure (10).
