摘要： A system usable with a pipe laying vessel, includes a support frame, such as a deck frame of the vessel, and a loader arm which is movable between a loading position and an upright position. The loader arm is provided with a pipe section manipulation system. A first clamping member is provided having a substantially fixed position with respect to the support frame. The first clamping member is operable between a clamped position for supporting the weight of the pipeline, and a released position for allowing the pipeline to be lowered. A second clamping member is movable between an upper position and a lower position. The second clamping member is operable between a clamped position for supporting the weight of the pipeline during movement from the upper position to the lower position, and a released position for moving the second clamping member from the lower position to the upper position.

摘要： In a pipe joint where two pipe sections (14, 16) have threadably engaged end portions (17, 18), joint ends (32, 34) are substantially sealed to each other by a sealing surface (40, 50) on one pipe section that substantially abuts a sealing surface (42, 52) on the other pipe section. In one joint, a ring-shaped cutout (121, FIG. 7) is formed in a first pipe section and a ring-shaped spacer (120) is located in the cutout. The spacer is chosen from several that have slightly different lengths so the spacer end contacts the corresponding sealing surface (130). In a pipe string used to carry corrosive fluid, the inner surface (44) of adjacent pipe sections is covered with a corrosion resistant coating (70, 72). Where the sealing surface is connected to a rounded corner (82, 84), the coating extends to and along the sealing surfaces (40, 42). Where there are sharp corners (80) at the intersection of the inside surface (40) with the sealing surface (40B, 42B), the coating does not extend along the sealing surfaces.

摘要： A riser connector connects the upper portion of a riser (12) having a latching enlargement (32) to a receptacle (14) on a vessel (16), so the riser upper end (22) can connect to a fluid coupling (42) leading to a conduit (40) on the vessel. A double-click mechanism (88), with parts on the enlargement and on the receptacle, turns a load ring on the enlargement to latch the enlargement in place when it is lifted to an upper position and lowered to a latched position, and releases it by again lifting and lowering. A cable coupling (24) is temporarily mounted on the top of the riser to enable the riser to be lifted by a cable (26), the cable coupling being later removed to connect the riser upper end to the fluid coupling on the vessel.

摘要： A pipe string (44) is pulled out by a tug boat (30) from a floating structure (12) such as a production vessel, as pipe sections (54, 56) are connected in series on the vessel, to eventually lay the pipe string in a catenary curve from the vessel to the sea floor and then along the sea floor to a distant subsea well head (86). To save time and cost in coupling the pipe sections, lower fatigue resistant pipe couplings, such as non weld-on couplings (120) that include a threaded sleeve (134), are used to connect pipe sections that will lie in a quiescent zone such as on the sea floor (zone Az), and in a zone (Cz) lying along the middle of the catenary curve. Higher fatigue resistant pipe couplings such as weld-on couplings (150) are used along active zones such as top and bottom zones (Dz, Bz) of the catenary curve.

摘要： A pipeline (20) that lies primarily in the sea and that consists of multiple steel pipe sections connected in tandem at pipe joints, includes a protective coating around the pipe sections and around the pipe joints. Each pipe section is first covered, at an onshore facility, by an initial coating (30, 32) that extends along at least 80% of the pipe section length while leaving its ends uncovered, to leave gripping areas (40, 42) where the steel of the pipe is uncovered so the pipe can be clamped by tools such as those with steel jaws to position and slide it axially, or turn it, or prevent it from turning. After a pair of pipe sections are connected, a completion coating (50) is applied around the pipe joint to leave the pipeline with a coating around all of it.

摘要： An elastomeric flex joint is provided with a rotational bearing so that torsional stress is relieved by slip of the rotational bearing. In a first embodiment, the flex joint is designed to resist flexing from a mean position at which there is a substantial bend of axial direction, and the rotational bearing does not normally slip. An adjustment mechanism reduces the loading on the elastomeric flex element and the rotational bearing so that the bearing will slip during an initial orientation or during an adjustment of the joint. In a second embodiment, all small torsional deflections are absorbed by the elastomeric flex element, and large torsional deflections are absorbed by the rotational bearing. This is desirable because the elastomeric flex element has a greater fatigue capacity for small oscillations than the rotational bearing. An elastomeric clutch can be used to precisely control the break-out torque.
摘要翻译： 弹性柔性接头设置有旋转轴承，使得扭转应力通过旋转轴承的滑动而减轻。 在第一实施例中，柔性接头被设计成抵抗从轴向方向上的实质弯曲的平均位置的弯曲，并且旋转轴承通常不滑动。 调节机构减少弹性体柔性元件和旋转轴承上的载荷，使得轴承在初始取向期间或在接头调整期间滑动。 在第二实施例中，所有小的扭转偏转被弹性体挠曲元件吸收，并且大的扭转偏转被旋转轴承吸收。 这是理想的，因为弹性挠曲元件具有比旋转轴承更小的振荡的疲劳能力。 可以使用弹性离合器来精确地控制分离扭矩。
