Abstract

A system includes a plug configured to restrict release of hydrocarbons from a terminal end of an offshore riser by accumulating the hydrocarbons at the plug when the plug is disposed in an internal portion of the offshore riser and at a first vertical location of the offshore riser. The system also includes a vent configured to be disposed at a second vertical location, wherein the vent is configured to provide a path for the hydrocarbons to be released from the offshore riser.

What is claimed is: 
     
         1 . A system, comprising:
 a plug configured to restrict release of hydrocarbons from a terminal end of an offshore riser by accumulating the hydrocarbons at the plug when the plug is disposed in an internal portion of the offshore riser and at a first vertical location of the offshore riser; and   a vent configured to be disposed at a second vertical location, wherein the vent is configured to provide a path for the hydrocarbons to be released from the offshore riser.   
     
     
         2 . The system of  claim 1 , comprising a valve configured to control a flow of the hydrocarbons passing though the vent. 
     
     
         3 . The system of  claim 2 , comprising a vacuum configured to evacuate the hydrocarbons from the offshore riser via the vent. 
     
     
         4 . The system of  claim 3 , comprising a connector configured to couple the vacuum to the vent. 
     
     
         5 . The system of  claim 4 , wherein the connector comprises a stab connector. 
     
     
         6 . The system of  claim 1 , comprising a connector coupled to the offshore riser at a connection point at a third vertical location of the offshore riser. 
     
     
         7 . The system of  claim 6 , wherein the third vertical location is disposed above the first vertical location relative to a seafloor. 
     
     
         8 . The system of  claim 6 , wherein the connector is configured to be coupled to a blowout preventer. 
     
     
         9 . The system of  claim 1 , wherein the vent is disposed in the offshore riser below the first vertical location relative to a seafloor as the second vertical location. 
     
     
         10 . The system of  claim 1 , wherein the vent is disposed in the plug as the second vertical location. 
     
     
         11 . A system, comprising:
 a body comprising a terminal end and a second end, wherein the second end of the body is configured to be coupled to an offshore riser;   a plug configured to restrict release of hydrocarbons from the terminal end of the body by accumulating hydrocarbons at the plug when the plug is disposed in an internal portion of the body and at a first vertical location of the body; and   a vent configured to be disposed in the body at a second vertical location, wherein the vent is configured to provide a path for the hydrocarbons to be released from the offshore riser.   
     
     
         12 . The system of  claim 11 , wherein the body comprises a connector disposed at the second end of the body. 
     
     
         13 . The system of  claim 12 , wherein the connector is configured to engage with the offshore riser to couple the body to the offshore riser. 
     
     
         14 . The system of  claim 11 , comprising a valve configured to control a flow of the hydrocarbons passing though the vent. 
     
     
         15 . The system of  claim 14 , comprising a connector coupled to the terminal end of the body, wherein the connector is configured to be coupled to a blowout preventer. 
     
     
         16 . The system of  claim 11 , wherein the vent is disposed in the body below the first vertical location relative to a seafloor as the second vertical location. 
     
     
         17 . The system of  claim 11 , wherein the vent is disposed in the plug as the second vertical location. 
     
     
         18 . A system, comprising:
 a plug configured to restrict release of hydrocarbons from a terminal end of an offshore riser by accumulating the hydrocarbons at the plug when the plug is disposed adjacent to the offshore riser and at a first vertical location; and   a vent configured to be disposed at a second vertical location, wherein the vent is configured to provide a path for the hydrocarbons to be released.   
     
     
         19 . The system of  claim 18 , wherein the plug is configured to be disposed directly adjacent to the offshore riser as the first vertical location. 
     
     
         20 . The system of  claim 18 , wherein the plug is configured to be disposed directly adjacent a body, wherein the body comprises a terminal end and a second end, wherein the second end of the body is configured to be coupled to the offshore riser. 
     
     
         21 . A method, comprising:
 disposing a plug adjacent to an offshore riser at a first vertical location to restrict release of hydrocarbons from a terminal end of the offshore riser by accumulating the hydrocarbons at the plug; and   venting the hydrocarbons via a vent disposed at a second vertical location, wherein the vent is configured to provide a path for the accumulated hydrocarbons to be released.
