摘要： A mooring system for offshore vessels uses a chain stopper within a preset mooring line. The chain stopper has means for attaching a removable hydraulic chain jack actuator which may be used to stroke the chain through the stopper assembly while both the stopper and the mooring line remain under load.

摘要： A tension leg platform (TLP) (100, comprising buoyant columns (110, 510, 610, 710, 810, 910, 1010, 1110, 1210, 1310) having a generally polygonal transverse cross section and buoyant pontoons (112, 512, 712, 812, 912, 1112, 1212, 1312) interconnecting adjacent columns. In certain embodiments at least one axis of said polygonal transverse sections is generally radially aligned with a central vertical axis of the hull. Some embodiments comprise tendon porches (30a, 30b, 130, 930, 930', 1030, 1130) mounted on different surfaces of the buoyant columns. In one embodiment of the TLP, tendon porches (1192) are mounted to the outboard surface of the pontoons (1112). Also disclosed is a semi submersible (200, 300) comprising buoyant columns (210) with generally rectangular transverse section, an inboard surface, an outboard surface and a pair of opposing side surfaces, a plurality of pontoons, connected between adjacent columns. The pontoons of the tension leg platform and the semi-submersible are generally rectangular in cross section and the outboard, generally vertical surface of each pontoon may be connected to a side surface of an adjoining column at a location which is substantially inboard of the outermost face of the column (210).

摘要： A fairing for the reduction of vortex-induced vibration and the minimization of drag about a substantially cylindrical element immersed in a fluid medium. The fairing also eliminates the galloping phenomenon typically associated with a teardrop- shaped fairing. The fairing having a U-shaped cylindrical shell with opposing edges defining a longitudinal gap and parallel fins extending outwardly from the opposing edges of the shell, the parallel fins being positioned so as to reduce vortex-induced vibration, minimize drag and to eliminate the galloping phenomenon on the cylindrical element.

摘要： Flexible hang-off arrangement is provided for a catenary riser suspended from an offshore or inshore platform, which includes floating or fixed platforms, vessels or/and buoys. The bending loads in the top segments (209) of the said riser are reduced by incorporating a pivot (201) at the riser hang-off. Pressure containing welded, bolted, rolled or swaged pipe spools transfer fluids, including hydrocarbons between the riser and the platform. Along significant spool lengths the tangents to the center lines of said spools are orthogonal to and offset from the tangent to the center line of the riser at the hang-off. The said pressure containing spools include arbitrary looped, spiral (237) and helicoidal designs that are subject to torsion.

摘要： A floating platform system supports one or more decks (14) above the water surface for accommodating equipment to process oil, gas and water recovered from a subsea hydrocarbon formation. The platform is secured to the seabed by one or more tendoms (17). A central column (12) of the platform includes a moonpool (19) extending axially through the central column (12). The moonpool (19) is open at the lower and upper ends thereof. Riser lateral restraint members (32) are supported within the moonpool (19) for laterally restraining risers (16) disposed in the moonpool (19) and minimizing riser spacing and riser deflection.

摘要： For use with a subsea well incorporating an external condutor pipe (12) extending upwardly above the seabed, a protector apparatus is set forth. A longitudinally split, flange, equipped, bolt joined elongate conductor clamp is supported on a frame (16) at the bottom thereof and has a plurality of appended upstanding braces (70). The bottom frame is adapted to be rested on a seabed and held in place by a number of anchors (20) driven into the seabed at corners. This apparatus is selectively installed after completion of a well wherein the condutor pipe extends above the bottom, and the apparatus is subsequently removed after protecting the pipe after drilling but before installation of a platform.

摘要： A disconnectable buoyant turret mooring system for an FPSO is vulnerable to damage from collisions between the buoy and the buoy turret cage during mating and de-mating operations. It is therefore desirable that the buoy separate quickly from the turret of the FPSO vessel during a disconnect operation. A buoy turret cage is provided with a certain degree of porosity that allows a flow of seawater from the outside of the receptor to the inner surface of the receptor. Introducing water in this way relieves the suction forces and allows for a quicker separation of the buoy from the turret of the FPSO vessel, minimizing the time during which an uncontrolled collision between the buoy and the FPSO vessel is most likely. Filling a portion of the turret above the mooring buoy with water prior to releasing the buoy also decreases the separation time.

摘要： A floating, offshore drilling and/or production platform is equipped with a rail-mounted transport system that can be positioned at a plurality of selected positions over the well bay of the vessel. The transport system can move a drilling riser with a drilling riser tensioner system and a blowout preventer from one drilling location to another without removing them from the well bay of the vessel. Using the transport system, the drilling riser is lifted just clear of a first well head and positioned over an adjacent, second well head using guidelines. The transport system may then move the upper end of the drilling riser (together with its attached tensioner and BOP) to a second drilling location. A dummy wellhead may be provided on the seafloor in order to secure the lower end of the drilling riser without removing it from the sea while production risers are being installed.
