    摘要： A subsea well intervention cap is provided. The subsea well intervention cap includes a frame, a first clamp segment coupled to the frame and configured to be fitted over a horizontally oriented flowpath of a subsea well equipment component, and a second clamp segment having a rim segment configured to interface with the first clamp segment, wherein the second clamp segment is movable with respect to the first clamp segment. The subsea well intervention cap also includes an actuation mechanism coupled to the frame that actuates the second clamp segment in a vertically upward direction and in an axial direction with respect to the frame toward the first clamp segment. The subsea well intervention cap is lightweight and able to be installed on subsea well equipment using a standard remote operated vehicle (ROV).

    摘要： A rotating head assembly includes a body, an implement, a clamp assembly, a drive member, a hydraulic motor, and a bypass circuit. The drive member is threadingly connected to a first clamp member and a second clamp member. The hydraulic motor is connected to the drive member to cause the drive member to rotate in a selected direction. An inlet of the bypass circuit is in fluid communication with an inlet of the hydraulic motor to receive a portion of the pressurized hydraulic fluid passing to the hydraulic motor. An outlet of the bypass circuit is in fluid communication with the outlet of the hydraulic motor. At least one bypass valve is interposed between the inlet of the bypass circuit and the outlet of the bypass circuit. The bypass valve has an actuator positioned adjacent one of the first clamp member and the second clamp.

    摘要： A high capacity universal connector for use in connecting tubular members and a method for sealing the tubular members is provided. First and second tubular members are provided which each have ends that are brought into face-to-face engagement by a connector. A metal sealing element seals against conical surfaces at the ends of the first and second tubular members and enables the entire surface of the end of one tubular member to be bought into engagement with the surface of the end of the other tubular member so as to improve the bending and compression capacity of the assembly comprising the tubular members and the metal sealing element. A metal sealing ring for use in this assembly is also provided, along with a gasket retention assembly.

    摘要： A subsea hydrocarbon production field includes a number of first subsea christmas trees, a first manifold, a number of first flexible flowline jumpers, each of which is connected between the first manifold and a corresponding first tree. Each first flowline jumper includes a first flow conduit and a number of first umbilical lines, and each first flowline jumper includes a first end which is removably connected to a corresponding first tree by a first multibore hub and connector arrangement and a second end which is removably connected to the first manifold by a second multibore hub and connector arrangement.

    摘要： Systems and methods for initiating an emergency disconnect sequence (EDS) are provided. In an aspect, a disconnection system is provided and configured to initiate the EDS, and includes a controller including a processor and a memory operably coupled to the processor. The controller receives, from a set of motion reference units (MRU(s)) operably coupled to a flexible joint, position data generated by the set of motion references units and associated with the joint when the joint is operably coupled to and disposed between a drilling riser and a lower marine riser package (LMRP). The controller determines, based on the position data, an angular offset of the joint. The controller sends, to a subsea control pod disposed at or adjacent to the LMRP, a trigger signal in response to determining that the angular offset exceeds a predetermined threshold, such that the subsea control pod initiates the EDS.

    摘要： A system for tethering a subsea blowout preventer (BOP) or well head is disclosed. In at least one embodiment, the system comprises an interface associable with the BOP, and more than one anchors disposed about the BOP. Each anchor is configured to carry or support a tensioning system arranged in operable association with a respective tether. Each tether is arranged so as to link a respective anchor with a respective operable means associated with the BOP. Furthermore, each of the respective operable means are configured in operable association with the interface such that tension in the tethers can be adjustable either individually or together as a group of two or more tethers, by way of the interface.
