  • Patent number: 10323474
    Abstract: In accordance with embodiments of the present disclosure, system and methods for controlling borehole pressure in a MPD system to compensate for heave effects on a drilling rig are provided. The systems and method described herein involve calculating and implementing set points for two or more MPD system components in real time. These MPD components that are controlled via the dynamic set points may include a choke, a backpressure pump (BPP), a rig pump diverter (RPD), a continuous circulation device, one or more mud pumps, a pressure relief system, or some combination thereof. By calculating and providing these set points in real-time during various well and drilling operations, non-productive time, well control events, and costs to remedy issues resulting from improper pressure levels within the borehole may be mitigated or avoided.

  • Patent number: 10024121
    Abstract: Flexible riser hang-off for rigid risers deployed offshore is provided and called a spoolflex hang-off. The spoolflex hang-off utilizes combined torsional and bending flexibilities of a rigid tubular jumper deployed between a top of the riser and a floater piping. The rigid jumper transports fluids, contains the fluid pressure and accommodates angular deflections of the riser. The riser top is suspended from a pivoting arrangement that transfers the riser tension to the floater structure. The rigid jumper can be made of titanium or of other metallic or nonmetallic materials. The flexible riser hang-off provided has rotational stiffness independent on riser tension. Low static and fatigue bending loads on the riser and on the floater structure result. The hang-off allows large riser deflection angles.

    Abstract: A tensions compensator assembly for a slip type joint in an offshore work string. The assembly includes a chamber at the joint which is constructed in a manner to offset or minimize a pressure differential in a production channel that runs through the work string. Thus, potentially very high pressures running through the string are less apt to prematurely force actuation and expansiveness of the slip joint.

  • Patent number: 9133670
    Abstract: The riser system of the present invention includes an external production riser for floating structures with interfaces to the dry and subsea wellheads, internal tieback riser with a special lower overshot/slipping connector for elevated temperatures. The seals can be metallic and/or non-metallic dynamic seals. Special centralizing pipe connectors and a special subsea wellhead tubing hanger are also included. This riser system avoids the penalty of pipe within pipe differential thermal growth and the resulting unwanted effects on the floating structure. This is accomplished by allowing an overshot sealing slipping connector to swallow an expanding polished rod as thermal conditions cause pipe elongation axially. When elevated temperatures fall to ambient the opposite occurs as the pipe shrinks axially. Alternatively, a system is possible where a two pipe drilling riser is needed. The internal pipe in this case would be an inner riser rather than a tubing string.

  • Patent number: 9010436
    Abstract: A tensioner assembly for applying tension to a tubular member, such as a riser, can include an upper latch connected to the tubular member, a platform with a bore, and a lower latch ring. After applying tension to the tubular member, the lower latch ring can be closed around the tubular member so that when the tension is released, the upper latch lands on and engages the lower latch. The assembly can include a locking mechanism that prevents axial movement of the upper latch, relative to the lower latch, after engagement. The upper latch can self-center on the lower latch as it is moved into the latching position.

  • Patent number: 8960304
    Abstract: An underwater fluid transport apparatus (10) to transport a fluid between a sea bed (12) and the surface (14) of the sea vertically above the sea bed. A riser (20) is connected to a flexible pipe (32) leading to the sea surface (14). A retaining float (24) is installed around the riser in order to maintain the riser (20) in a stretched suspended position between the sea bed (12) and a subsurface region situated between the sea bed and the surface (14) of the sea. The flexible pipe (32) extends in a catenary curve between the riser (20) and the sea surface. An additional float (28) is installed between the riser (20) and the sea surface (14). The riser (20) is attached to the additional float (28) to increase the buoyancy of the riser.

  • Patent number: 8955596
    Abstract: Provided is a damping apparatus for a moonpool, which has a simple driving mechanism. The damping apparatus includes one or more damping plates which cover a moonpool of a hull entirely or partially. The damping plates are pivotally hinged to a sidewall of the moonpool, and one or more conveying units are disposed above the moonpool to convey drilling equipment. Driving wires are coupled between the conveying units and the damping plates, and the conveying force of the conveying units is transferred through the driving wires to the damping plates. Thus, the damping plates are pivoted to open and close the moonpool entirely or partially.
