Floating facility mounted with power plant

Abstract

This invention relates to a floating facility mounted with a power plant. The floating facility mounted with a power plant includes: at least one power generator room disposed respectively in both ends within a hull of the floating facility; and at least one fuel tank disposed in a central portion within the hull.

What is claimed is: 
     
         1 . A floating facility mounted with a power plant, comprising:
 at least one power generator room disposed respectively in both ends within a hull of the floating facility; and   at least one fuel tank disposed in a central portion within the hull.   
     
     
         2 . The floating facility according to  claim 1 , wherein the center of gravity of the floating facility is lowered by disposing the power generator room and the fuel tank within the hull. 
     
     
         3 . The floating facility according to  claim 1 , wherein ballast tanks are disposed respectively in both ends of the floating facility. 
     
     
         4 . The floating facility according to  claim 3 , wherein the weight of both ends of the floating facility is reduced by filling the ballast tanks with seawater first and then discharging the seawater when fuel in the fuel tank is consumed. 
     
     
         5 . The floating facility according to  claim 1 , wherein at least one transmission tower is provided in an upper deck of the power generator room to transmit electricity produced in the power generator room to the exterior of the floating facility. 
     
     
         6 . The floating facility according to  claim 1 , wherein fuel used for power generation in the power generator room is liquefied natural gas (LNG), and a vaporizer for vaporizing the LNG stored in the fuel tank and supplying the vaporized LNG to the power generator room as power generation fuel is provided on an upper deck of the floating facility. 
     
     
         7 . The floating facility according to  claim 1 , wherein the power generator room is partitioned into a plurality of sub power generator rooms, and watertight bulkheads are provided between the sub power generator rooms. 
     
     
         8 . The floating facility according to  claim 1 , wherein a plurality of main engines is provided in the power generator room, and the plurality of main engines are provided to face opposite directions. 
     
     
         9 . The floating facility according to  claim 1 , wherein a space ratio of the at least one power generator room to the at least one fuel tank within the hull of the floating facility ranges from 30:70% to 50:50%. 
     
     
         10 . The floating facility according to  claim 1 , wherein the power generator room generates power by using an ME-GI engine as a main engine. 
     
     
         11 . An arrangement method of a floating facility mounted with a power plant, comprising:
 at least one power generator room and at least one fuel tank disposed under a deck of the floating facility,   wherein the power generator room is disposed respectively in both sides under the deck,   the fuel tank is disposed in a central portion under the deck, and   a space ratio of the power generator room to the fuel tank ranges from 30:70% to 50:50%.   
     
     
         12 . The arrangement method according to  claim 11 , wherein a transmission tower is provided on an upper deck of the power generator room to transmit electricity produced in the power generator room. 
     
     
         13 . The arrangement method according to  claim 11 , wherein ballast tanks are disposed in both ends of the floating facility, and the weight of both ends of the floating facility is reduced by filling the ballast tanks with seawater first and then discharging the seawater when fuel in the fuel tank is consumed.
