Catwalk System

Abstract

A catwalk system comprising a catwalk suitcase and a tubular handling catwalk. The catwalk suitcase may have a base configured to receive the tubular handling catwalk, and a ramp connected with the base and configured to extend diagonally to a drill rig floor located at an oil and gas wellsite. The ramp may be configured to facilitate movement of tubulars from the tubular handling catwalk to the drill rig floor.

What is claimed is: 
     
         1 . An apparatus comprising:
 a base configured to receive a tubular handling catwalk; and   a ramp connected with the base and configured to extend diagonally to a drill rig floor located at an oil and gas wellsite, wherein the ramp is configured to facilitate movement of tubulars from the tubular handling catwalk to the drill rig floor.   
     
     
         2 . The apparatus of  claim 1  wherein the tubular handling catwalk is one of a plurality of tubular handling catwalks, and wherein the base is configured to receive each tubular handling catwalk one at a time. 
     
     
         3 . The apparatus of  claim 1  wherein the base is configured to detachably connect with the tubular handling catwalk. 
     
     
         4 . The apparatus of  claim 1  wherein the base is configured to support the tubular handling catwalk thereon. 
     
     
         5 . The apparatus of  claim 1  wherein the base comprises:
 a horizontal portion configured to be disposed at ground level of the oil and gas wellsite; and 
 a vertical portion fixedly connected with the horizontal portion, wherein the ramp is connected with an upper end of the vertical portion, and wherein the horizontal and vertical portions define a space configured to receive the tubular handling catwalk. 
 
     
     
         6 . The apparatus of  claim 1  wherein the base comprises:
 a frame; and 
 a fluid conduit extending along the frame. 
 
     
     
         7 . The apparatus of  claim 6  wherein the fluid conduit is configured to convey a kill weight fluid during well kill operations at the oil and gas wellsite. 
     
     
         8 . The apparatus of  claim 1  wherein the ramp comprises:
 a frame; and 
 a fluid conduit extending along the frame of the ramp. 
 
     
     
         9 . The apparatus of  claim 8  wherein the fluid conduit is configured to convey a cement slurry from a ground level of the oil and gas wellsite to the drill rig floor during cementing operations at the oil and gas wellsite. 
     
     
         10 . The apparatus of  claim 1  further comprising a fluid conduit connected with and extending longitudinally along the base and ramp. 
     
     
         11 . The apparatus of  claim 10  wherein the fluid conduit is configured to convey a cement slurry from a ground level of the oil and gas wellsite to the drill rig floor during cementing operations at the oil and gas wellsite. 
     
     
         12 . An apparatus comprising:
 a catwalk suitcase comprising:
 a base configured to detachably connect with a tubular handling catwalk; 
 a ramp connected with the base and configured to extend to a drill rig floor located at an oil and gas wellsite, wherein the ramp is configured to facilitate movement of tubulars from the tubular handling catwalk to the drill rig floor; and 
 a plurality of fluid conduits connected with and extending along the base and/or ramp. 
   
     
     
         13 . The apparatus of  claim 12  wherein the base comprises:
 a horizontal portion configured to be disposed at ground level of the oil and gas wellsite; and 
 a vertical portion fixedly connected with the horizontal portion, wherein the ramp is connected with an upper end of the vertical portion, and wherein the horizontal and vertical portions define a space configured to receive the tubular handling catwalk. 
 
     
     
         14 . The apparatus of  claim 12  wherein at least one of the fluid conduits is configured to convey a kill weight fluid during well kill operations at the oil and gas wellsite. 
     
     
         15 . The apparatus of  claim 12  wherein at least one of the fluid conduits is configured to convey a cement slurry from ground level of the oil and gas wellsite to the drill rig floor during cementing operations. 
     
     
         16 . A method comprising:
 installing a catwalk suitcase at an oil and gas wellsite such that a base of the catwalk suitcase is disposed at a ground level of the oil and gas wellsite and a ramp of the catwalk suitcase extends to a rig floor of a drill rig;   detachably connecting a tubular handling catwalk with the base; and   moving tubulars from the tubular handling catwalk to the rig floor via the ramp.   
     
     
         17 . The method of  claim 16  further comprising:
 disconnecting the tubular handling catwalk from the base; 
 detachably connecting another tubular handling catwalk with the base; and 
 moving tubulars from the another catwalk to the rig floor via the ramp. 
 
     
     
         18 . The method of  claim 16  wherein the catwalk suitcase comprises a fluid conduit connected with and extending along the base, and wherein the method further comprises conveying a kill weight fluid via the fluid conduit during well kill operations. 
     
     
         19 . The method of  claim 16  wherein the catwalk suitcase comprises a fluid conduit connected with and extending along the ramp, and wherein the method further comprises conveying a cement slurry via the fluid conduit during cementing operations. 
     
     
         20 . The method of  claim 16  wherein the catwalk suitcase comprises a fluid conduit connected with and extending along the base and the ramp, and wherein the method further comprises conveying a cement slurry via the fluid conduit during cementing operations.
