Oil and gas industry gooseneck manufactured by hot isostatic pressing and a flexible pipeline assembly with an oil and gas industry gooseneck

Abstract

The present invention relates to an oil and gas industry gooseneck with a fluid duct portion with at least an arch shaped portion, a first connecting portion, a second connecting portion a lifting pad eye and a shackle interface along the arch shaped fluid duct portion. The gooseneck is one Hot Isostatic Pressed element. An oil and gas industry flexible pipeline assembly with a hipped gooseneck is also disclosed.

1 . An oil and gas industry gooseneck comprising a fluid duct portion with at least an arch shaped portion, a first connecting portion, a second connecting portion, a lifting pad eye with a shackle interface extending along the arch shaped fluid duct portion, and
 wherein the gooseneck is one hot isostatic pressed element.   
     
     
         2 . The gooseneck of  claim 1 , wherein the gooseneck is made of a Super-duplex material. 
     
     
         3 . The oil and gas industry goose neck of  claim 1  wherein the lifting pad eye extends along a convex part of the fluid duct portion. 
     
     
         4 . The oil and gas industry goose neck of  claim 1  wherein the lifting pad eye is plate shaped. 
     
     
         5 . An oil and gas industry flexible pipeline assembly comprising an oil and gas industry gooseneck of  claim 1 , and a flexible pipeline with a first end connected to the second connecting portion and a second end connected onto a subsea host structure. 
     
     
         6 . The oil and gas industry flexible pipeline assembly of  claim 5 , further including a guiding structure with a clamp connector connected to the first connecting portion. 
     
     
         7 . The oil and gas industry flexible pipeline assembly of  claim 6 , wherein the guiding structure with a clamp connector is adapted to be connected to a guiding structure with a female hub assembled to a subsea structure. 
     
     
         8 . Use of hot isostatic pressing to manufacture an oil and gas industry gooseneck of  claim 1 .
