Abstract:
1. A device that enables evacuation of hydrocarbons from a plurality of nested tubulars of an underwater well pipe extending from an underwater well tree, comprising: a) a first fluid transmission line attached to the underwater well tree, the fluid transmission line having one end portion forming an attachment to the tree and the other end portion attached to a pump that enables transmission of fluid under pressure to the tree and nested tubulars attached to the tree; b) one or more openings formed through one or more tubulars of the nested tubulars at a selected location; c) a fitting that seals the openings, the fitting having an expandable seal that is expandable responsive to rotation of a rotating member that rotates upon a saddle, the saddle surrounding a mandrel and bearing against an outer tubular of the nested tubulars; d) wherein the fitting has a bore and enabling hydrocarbons to escape from the tubulars via the bore; e) a second fluid transmission line attached to the fitting; and f) a collection vessel that receives hydrocarbons from the second fluid transmission line.
