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.
