Abstract
A method of evacuating hydrocarbons from a plurality of nested tubulars of a well pipe, extending from an underwater well tree, includes attaching a fluid transmission line to the underwater well tree, the fluid transmission line having one end portion forming the attachment to the tree and the other end portion attached to a pump that forces fluid under pressure to the tree and attached nested tubulars. Openings are formed through one or more tubulars at a selected location. A specially configured fitting is attached to the tubulars. The fitting seals the openings. The fitting has an expandable seal that is expandable responsive to rotation of a rotating member that rotates upon a saddle, pulling a tapered mandrel against the seal. The saddle surrounds the mandrel and bears against an outer tubular of the nested tubulars. The fitting mandrel has a bore through which hydrocarbons escape from the tubulars.
