Abstract: The present invention discloses a process for installing a floating platform (20) to the ocean floor using a spoolable tether (15), comprising installing the spooled tether onto the floating platform; towing the floating platform to a site for installation; unspooling the tether; connecting a bottom end connector (45) of the tether to a foundation (75) on the ocean floor; and connecting a top end connector of the tether to the floating platform. A preferred floating platform is a tension leg platform, and the invention includes a novel tension leg platform (TLP) comprising a spooled tether (15) installed thereon. In a preferred embodiment the foundation (75) is a suction anchor (100), and the suction anchor (100) is connected to the bottom end connector (45) prior to unspooling the tether and attached to the ocean floor after unspooling the tether. The floating platform may be installed, moved and re-installed according to the invention.

Abstract: The present invention includes a nontwisted composite tether comprising one or more composite rods encased in a jacket and a method for manufacturing same. A portion of the rods may be bundled into one or more strands, provided however that the rods comprising the strands are not twisted into twisted strands in the assembled nontwisted tether. Such untwisted strands, if any, additionally are not twisted relative to each other. Temporary and/or permanent buoyancy may be to the tether. The present invention includes methods for preparing, transporting, and installing a composite tether on a floating platform. The tether, preferably assembled at a waterfront, is launched into the water and towed to an offshore installation site, where the tether is upended and connected via a bottom end connector on the tether to an anchor foundation in the seabed and connected a top end connector on the tether to the floating platform.

Abstract: The present invention discloses redundant sealing systems for composite risers having metal liner assemblies and methods of preventing interior fluid leakage to the outside of composite risers. An elastomeric seal is formed between an elastomeric tip provided on the end of a metal to composite interface (MCI) of the liner assembly and an elastomeric shear ply provided over the liner assembly. The elastomeric seal and a mechanical seal between the MCI and a transition ring which secures the liner to the MCI, provides a dual sealing system for the composite riser to prevent leakage of interior fluids. In the event that the integrity of the mechanical seal or the integrity of the liner is compromised, the elastomeric seal would prevent leakage of the fluid to the outside of the composite riser.

Abstract: A composite riser 100 is joined to an end connector at a Metal to Composite Interface (MCI) 230. A transition ring 270 is secured to a lining section 110 and sealed against the end of the MCI, and an elastomeric seal 264 is provided on the end of the MCI. An elastomeric shear ply extends over the liner 110, transition ring 270, seal 264 and MCI 230. The shear ply and seal are cured after assembly so that they bond to form a seal along their interface 266. This seal can be provided in addition to the seal formed by conforming surfaces 272.

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.
