Floating hydrocarbon treating plant

Abstract

A floating hydrocarbon treating plant containing a vessel having a hull and a deck and having tanks located below the deck for storing hydrocarbons, and a plant for treating hydrocarbons located at the deck of the vessel is provided. The plant for treating hydrocarbons includes spaced-apart modules, wherein each module has related plant equipment mounted on a module floor, and the modules rest on closed support girders that extend under the module in a direction perpendicular to the edge of the deck, and wherein the module floor is secured to one of the closed support girders.

1 . A method for treating hydrocarbons comprising using a floating hydrocarbon treating plant comprising a vessel having a hull and a deck and comprising tanks located below the deck for storing hydrocarbons, and a plant for treating hydrocarbons located at the deck of the vessel, wherein the plant for treating hydrocarbons includes spaced-apart modules, wherein each module comprises related plant equipment mounted on a module floor, and the modules rest on at least two closed support girders that extend under the module in a direction perpendicular to the edge of the deck, and wherein the module floor is secured to only one of the closed support girders. 
   
   
       2 . The method of  claim 1  wherein the floating hydrocarbon treating plant further comprises a pipe-rack supporting pipes that form the fluid connection between the equipment, which pipe-rack extends along the centreline of the vessel, wherein the modules are arranged at either side of the pipe-rack. 
   
   
       3 . The method of  claim 2  wherein the pipes are located above the level of the module floor. 
   
   
       4 . The method of  claim 1  wherein the deck is a double deck consisting of an upper deck and a lower deck. 
   
   
       5 . The method of  claim 1  wherein the plant for treating hydrocarbons comprises a plant for liquefying natural gas. 
   
   
       6 . The method of  claim 5  wherein the plant for treating hydrocarbons further comprises a plant for removing heavy hydrocarbons from natural gas. 
   
   
       7 . The method of  claim 2  wherein the deck is a double deck consisting of an upper deck and a lower deck. 
   
   
       8 . The method of  claim 3  wherein the deck is a double deck consisting of an upper deck and a lower deck. 
   
   
       9 . The method of  claim 2  wherein the plant for treating hydrocarbons comprises a plant for liquefying natural gas. 
   
   
       10 . The method of  claim 3  wherein the plant for treating hydrocarbons comprises a plant for liquefying natural gas. 
   
   
       11 . The method of  claim 4  wherein the plant for treating hydrocarbons comprises a plant for liquefying natural gas. 
   
   
       12 . The method of  claim 5  wherein liquefied natural gas is obtained. 
   
   
       13 . The method of  claim 9  wherein liquefied natural gas is obtained. 
   
   
       14 . The method of  claim 10  wherein liquefied natural gas is obtained. 
   
   
       15 . The method of  claim 11  wherein liquefied natural gas is obtained. 
   
   
       16 . A method of treating hydrocarbons comprising using a floating hydrocarbon treating plant comprising a vessel having a hull and a deck and comprising tanks located below the deck for storing hydrocarbons, and a plant for treating hydrocarbons located at the deck of the vessel, wherein the plant for treating hydrocarbons includes spaced-apart modules, wherein each module comprises related plant equipment mounted on a module floor, and the modules rest on at least two closed support girders that extend under the module in a direction perpendicular to the edge of the deck, and wherein the module floor is secured to one of the closed support girders and further comprising a pipe-rack supporting pipes that form the fluid connection between the equipment, which pipe-rack extends along the centreline of the vessel, wherein the modules are arranged at either side of the pipe-rack. 
   
   
       17 . The method of  claim 16  wherein the pipes are located above the level of the module floor. 
   
   
       18 . The method of  claim 16  wherein the deck is a double deck consisting of an upper deck and a lower deck. 
   
   
       19 . The method of  claim 16  wherein the plant for treating hydrocarbons comprises a plant for liquefying natural gas. 
   
   
       20 . The method of  claim 19  wherein the plant for treating hydrocarbons further comprises a plant for removing heavy hydrocarbons from natural gas. 
   
   
       21 . The method of  claim 17  wherein the deck is a double deck consisting of an upper deck and a lower deck. 
   
   
       22 . The method of  claim 17  wherein the plant for treating hydrocarbons comprises a plant for liquefying natural gas. 
   
   
       23 . The method of  claim 18  wherein the plant for treating hydrocarbons comprises a plant for liquefying natural gas. 
   
   
       24 . The method of  claim 16  wherein the module floor is secured to only one of the closed support girders. 
   
   
       25 . The method of  claim 19  wherein liquefied natural gas is obtained. 
   
   
       26 . The method of  claim 22  wherein liquefied natural gas is obtained. 
   
   
       27 . The method of  claim 23  wherein liquefied natural gas is obtained.
