Abstract: A monolithic isolation stress joint is disclosed having a first conduit element, a first insulating joint assembly, and a stress joint connected to the first conduit element through the first insulating joint assembly. The stress joint is formed of a material which has advantageous elastic flexure characteristics but which is electrochemically active with respect to the first conduit element from which it is electrically isolated by the first insulating joint assembly. A second conduit element is connected to the stress joint through a second insulating joint assembly, the second conduit element being formed of a material which is electrochemically active with respect to the stress joint and which is electrically isolated therefrom with the second insulating joint.

Abstract: An installation for producing oil from an off-shore deposit has a semi-submersible platform, at least one riser connecting the platform to the sea bed, and devices for tensioning the riser. The tensioning devices include, for each riser, at least one submerged float connected to a point on the main run of the riser for hauling it towards the surface, and a mechanism for hauling the riser. The mechanism is installed on the platform and applied to the top end of the riser.

Abstract: Where a submarine wellhead is coupled to a floating vessel by a riser in the form of a flexible hose, vessel movements subject the riser to excessive strains where the riser is tethered ask to the vessel. In accordance with the invention, these strains are reduced by pivoting the riser tether about a horizontal axis, and optionally also about a vertical axis. Giving the riser tether at least one degree of rotational freedom is surprisingly beneficial in reducing riser strains, and consequently in reducing the probability of premature failure of the riser.

Abstract: A riser connector is provided for connecting a riser to a wellhead assembly having a bore therethrough. The connector includes a housing having a first and a second end. The first end of the housing has an opening and is adapted for mounting to the wellhead assembly with the opening in communication with the bore of the wellhead assembly. The second end has a first opening connectable to the riser having a diameter at least the same as the inner diameter of the riser, and a second opening, having a diameter at least substantially the same as the diameter of the bore of the wellhead assembly. The housing further includes a first conduit connecting the opening in the first end of the housing to the first opening in the second end of the housing, and a second conduit connecting the opening in the first end of the housing to the second opening in the second end of the housing. In use, first well operations are conducted through the riser in the conventional manner. Second well operations are conducted using open water techniques and access the wellhead assembly and the well through the second conduit in the connector without the need to disconnect the riser from the connector. The riser connector is of particular use with risers having an inner diameter less than the diameter of the bore of the wellhead assembly, the second well operations being conducted using equipment which is too large to pass through the small bore riser.

Abstract: An apparatus for rapid venting of the compressed air and deballasting of a buoyant air tank in a positively buoyant riser system in the event of a premature drive off or a riser section parting is shown. The buoyancy tank or housing includes an annularly shaped flange positioned on its upper end and retained by explosive bolts. The inner circumference of the flange is sealed to the riser section supported by the buoyancy housing. A sensing means, activated by a parting of the riser, actuates the explosive bolts to release the annularly shaped flange and flood the buoyancy housing while restraining lines limit movement of the buoyancy housing with respect to the riser section.

Abstract: A cylindrical buoyancy unit is composed of separate sections which are held together to surround a marine object such as a riser or pipe with additional conduits. The sections combine to define an internal cavity which is shaped to conform with the marine object. Each unit section is a thermosetting resin composite with a bulk interior of syntactic foam and an outer layer of different characteristics and an intermediate reinforcement layer. The intermediate layer is disposed close to the outer layer and is mechanically embedded but not tightly bonded into the structure. The intermediate layer is made as a mesh of high strength polymer fibers.

Abstract: The present invention discloses multiple sealing systems for composite risers and methods of preventing interior fluid leakage to the outside of composite risers. Single or multiple elastomeric seals are formed between an elastomer applied in single or multiple grooves provided circumferentially along the outer surface of a metal to composite interface (MCI) of a liner assembly of the composite riser and an elastomeric shear ply provided on the outside of the liner assembly. The elastomeric seals and a seal between the MCI and the liner of the liner assembly provide a multiple sealing system for the composite riser to prevent leakage of interior fluids. In the event that the integrity of the seal between the MCI and liner fails or the integrity of the liner is compromised, the elastomeric seals would prevent leakage of the fluid to the outside of the composite riser.
