Abstract:
An interstitially insulated pipeline for flowing a hydrocarbon. In an embodiment, the pipeline comprises a first interstitially insulated pipe and a second interstitially insulated pipe. Each interstitially insulated pipe comprises an inner pipe, an outer pipe mounted coaxially around the inner pipe, an insulating interstice radially positioned between the inner pipe and the outer pipe, and a layer of screen mesh having a mesh size 10 or less disposed in the insulating interstice. In addition, the pipeline comprises a joint coupling the first interstitially insulated tubular and the second interstitially insulated tubular end-to-end. The joint includes a connection that couples the outer pipe of the first interstitially insulated pipe to the outer pipe of the second interstitially insulated pipe, and an annular seal member disposed between the inner pipe of the first interstitially insulated pipe and the inner pipe of the second interstitially insulated pipe.
Systems And Methods For Allowing Underwater Escape From A Submarine
US Patent:
6925954, Aug 9, 2005
Filed:
Feb 24, 2004
Appl. No.:
10/785145
Inventors:
Charles A. Bollfrass - Spring TX, US
International Classification:
B63G008/41
US Classification:
114323
Abstract:
A method for allowing underwater escape from a submarine includes attaching a lower escape tower connector of an escape tower to a hatch connector of a submerged submarine to sealingly attach a lower end of the escape tower to the submarine. A first riser tube is attached to an upper escape tower connector of the escape tower and second riser tube is attached to the first riser tube to form an escape tunnel. Water is replaced in an interior of the escape tower and a tunnel interior of the escape tunnel by air. An exterior hatch of the submarine is opened and a person passes through the hatch. The person is raised to the water surface through the tunnel.
