Abstract: The invention pertains to conduit assemblies, such as pipeline assemblies. A first conduit section comprises a first tubular conduit body. A second conduit section comprises a second tubular conduit body connected in end-to-end relation with the first conduit body. The bodies have opposed end faces. The second conduit section further comprises a tubular lining disposed within the second conduit body and having an inner diameter substantially equal to the inner diameter of the first conduit section. An annular seal sealingly engages between the opposed end faces of the conduit body, the seal being sufficiently rigid to maintain an axial gap between said end faces. The tubular lining extends beyond the end face of its respective conduit body into said axial gap and abuts the first conduit section at its inner diameter. Such extending portion of the tubular lining is preferably beveled on its outer side to form a lip at its inner diameter for noncompressive abutment with the first conduit section.
Abstract: The invention comprises a guard for disposition adjacent an offshore structure to protect the structure from impact. The guard comprises a tubular body of resilient material, at least one flexible positioning line extending longitudinally through the bore of the tubular body, and a pair of connectors joined to the positioning line or lines and disposed adjacent axially opposite ends of the tubular body for connection to the offshore structure.
Abstract: The present invention relates to a new and improved method and apparatus for installing and thereby protecting existing offshore structures, existing platforms and flow line risers in the splash and/or wave action zone.
