  • Patent number: 10125825
    Abstract: A hydraulic tool for moving a first structural element in the axial direction in relation to a second structural element. The tool comprises a ring-shaped frame configured for insertion into a gap between an annular shoulder on the first structural element and an annular shoulder on the second structural element; and hydraulic power members fixed to and distributed along said frame, the power members being configured to exert an axial pushing force against one of said annular shoulders to thereby move said structural elements apart. The frame comprises first and second arc-shaped sections, each of which having a hinged first end and an opposite second end. The arc-shaped sections are pivotable between an open position, in which their second ends are spaced apart, and a closed position, in which their second ends are in contact with each other.

  • Patent number: 9909690
    Abstract: A method of handling a discrete elongate subsea element of determinate length, such as a spool of rigid pipe is disclosed. The method includes shortening a tensile chord system acting on longitudinally-spaced locations on the element to apply longitudinally-compressive forces to the element. The compressive forces bend the element along its length against elastic recovery force to shorten the span of the element. One end of the element is anchored at a first anchorage before or after the element is bent. The other end of the element is anchored at a second anchorage, after the element is bent and while the element remains bent. The method is apt to be used during installation of the element, where the anchorages are both underwater, and during transportation of the element, where the anchorages are hang-off platforms of a surface vessel.

    Abstract: An accessory for a subsea pipeline such as an in-line tee having a rigid pipe support frame defining a pipe course and at least one carriage arranged to support a pipe or a fitting attached to a pipe. The carriage is movable with respect to the frame in a direction generally parallel to the pipe course. The carriage is attached to the frame via at least one angularly movable connection that allows a pipe or fitting supported by the carriage to tilt locally with respect to the frame as the pipe bends during laying. Pipe stiffness is therefore independent from the stiffness of the accessory. The stiffened section of the pipe is limited to a short length of the carriage. This is compatible with the small bending radius of the pipe on a stinger.

  • Patent number: 7942608
    Abstract: A flowline for hydrocarbon which is capable of being reeled and which is unreeled for being laid on the seabed using the reeled lay method is comprised of successive pipe sections having opposing ends which are joined by an anchor collar that is butt welded to the opposing ends. The pipe sections have a jacket on the exterior of the pipe sections, but the pipe sections are able to be reeled. Anchor collars are affixed by butt welding between the ends of adjacent pipe sections. Each anchor collar has a fixture or protrusion radially outward which has an outer diameter less than or at least not more than the outer diameter of the pipe section jacket. The flowline has the same inner diameter at the pipe sections and the collar, and the pipe has the same outer diameter as the collar, while the protrusion protrudes outward from the exterior of the collar.

  • Publication number: 20100329792
    Abstract: Controlled bending of a pipeline laying on the sea floor is achieved by attaching a bending sleeve assembly to a selected bending zone of the pipeline for limiting the controlled bending of the pipeline to a predetermined resulting bending configuration. External force is then applied on the bending sleeve assembly, bending the pipeline to the predetermined resulting bending configuration in cooperation with the bending sleeve assembly and the sea floor. External force can be exerted from one or more weights placed on top of the bending sleeve assembly. External force can be exerted from a winch attached to a wire, the wire passing through a pulley attached to a fixed structure, and the wire attached to the bending sleeve assembly. External force can be exerted through the bending sleeve assembly's contact reaction with an immobile object.

    Abstract: A device and a method for lowering or raising the end of an undersea pipe between a vessel and the sea bottom by a carriage moving along an inclined J-lay tower and co-operating with chain-locking devices connecting the top end of the pipe to a storage area by passing over a deflector sheave secured to said carriage. A first chain-locking device is secured to said carriage and serves to lock the abandonment chain while lowering said carriage and said top end of the pipe at the end of the chain, said second locking device then being in an open position at the base of said tower. Thereafter, said abandonment chain is locked at the low portion of the tower with the help of said second chain-locking device, with the first chain-locking device being in the open position while the carriage is being raised.

  • Patent number: 7556452
    Abstract: A bend-limiting conduit controls the curvature of a catenary riser extending from the seafloor as it enters the centerwell of a spar-type offshore platform through the keel of the platform. The conduit has a bore dimensioned to receive the riser, and it extends from an upper end constrained within the keel to a lower end disposed below the keel. The conduit has increasing flexibility and weight per unit length from the upper end to the lower end, which results in a lateral load being applied to the riser as it passes through the conduit, thereby causing a gentle and gradual transition in the riser from a curved configuration at the lower end of the conduit, to a straight configuration as it emerges from the upper end of the conduit.

  • Publication number: 20090103984
    Abstract: Gas Subsea Transmission System (GSTS) is a new method for transferring large quantities of natural gas between marine distances through the oceans. Its purpose is to provide a safer, faster and more financially advantageous alternative to gas transmission via LNG. The GSTS's main part is a Submersible Suspension Pressure-equaliser Pipeline (SSPP). It is a long pipe with a large diameter which has a high capacity of gas transmission. This pipe is kept submersible and suspended in deep waters by its special mooring system. It is made from steel pipe which is reinforced by internal concrete rings. The basic concept of SSPP is to cancel the internal pressure of the gas pipeline with the external hydrostatic water pressure by varying the pipe environment. These conditions lead to the possibility of a large diameter pipeline resulting in efficient, high capacity gas transmission.
