  • Patent number: 11738807
    Abstract: A trailer assembly for carrying coiled tubing includes a main beam assembly extending from a forward end of the trailer assembly to a rear end of the trailer assembly. The main beam assembly includes a forward portion that extends from the forward end of the trailer assembly, a rear portion that extends to the rear end of the trailer assembly, and a middle portion connected between the forward portion and the rear portion and configured to transfer load to the forward portion and the rear portion. The middle portion includes an upper beam section, and a lower beam section vertically separated from the upper beam section. The upper beam section is configured to share a load resultant from a bending force experienced by the lower beam section.

  • Patent number: 11608695
    Abstract: A coiled tubing injector system may include a coiled tubing injector guide configured for guiding coiled tubing into a coiled tubing injector and a remotely adjustable guide mechanism. The remotely adjustable guide mechanism may include a guide mount configured for adjustably securing the coiled tubing injector guide to a frame of the coiled tubing injector and a drive mechanism configured for remotely adjusting a position of the guide mount relative to the frame.

  • Patent number: 9353593
    Abstract: A handler holds a blowout preventer (BOP) assembly (partially or fully assembled) for transport and then erects it from a transport position to a vertical position for deployment. In the transport position the BOP assembly generally rests in a horizontal position. During deployment of the BOP assembly by the handler, the handler is capable of moving the BOP assembly to a vertical position, elevating it, and moving it outward, away from the base of the handler and toward a wellhead, so that the BOP assembly may be connected to a coiled tubing injector, work may be performed underneath the BOP assembly before connection to a well head, and the BOP assembly may be placed on top of a well head for connection to the well head.

  • Patent number: 9316067
    Abstract: A coiled tubing handler lifts and extends outwardly over wellhead a support platform on which a coiled tubing injector is mounted. The handler collapses into a compact arrangement that allows it and the coiled tubing injector to be transported to a well site on a vehicle or trailer, and then used at the well site to raise, position and support the coiled tubing injector connected to a blow out preventer and riser assembly for connection to a well head. The support platform may be tilted backward and forward, shifted from side-to-side, and raised and lowered on the platform.

  • Publication number: 20130175048
    Abstract: A coiled tubing support guide for maintaining an arch in a length of coiled tubing as it is unwound from a storage reel and feed into a coiled tubing injector connected with a wellhead is mounted to an elongated support structure rather than to the coiled tubing injector. The elongated support structure bears a load created by tension placed on the coiled tubing by the reel, thereby avoiding putting a bending moment on the wellhead. In alternate embodiment, a coiled tubing injector being held by a hoist line from the elongated support structure is coupled to the elongated support structure with a bending-resistant coupling that permits relative rotation of the coiled tubing injector.

  • Publication number: 20110070065
    Abstract: Wind energy device is composed of an enlarged main shroud structure with flare feature to capture more on-coming wind energy, and with wind flow swirling vane feature to force the captured wind flow to rotate. A multiple stage coaxial counter rotating fan system with duct feature is attached to the main shroud to boost the wind flow energy captured by the main shroud to increase the air power passing through the fan system. The coaxial counter rotating fan's rotating direction is opposite to the captured wind flow rotating one forced by the wind flow swirling vanes for higher fan efficiency. A multiple blade supply windmill with shroud feature is mounted to the coaxial counter rotating fan system to capture and convert on-coming wind energy and supply the power to drive the coaxial counter rotating fan system to achieve inputting more energy into the wind flow captured by the main shroud through the fan system.

  • Patent number: 7077209
    Abstract: A mast for lifting and suspending over a wellhead a coiled tubing injector and blow out preventer is pivotally mounted on a rear portion of a truck. The mast has two side-by-side telescoping legs that extend and retract synchronously. When in a retracted position, the blow out preventer and coiled tubing injector are attached to the mast, between the legs, and legs of the mast extended to lift the equipment.
