发明名称 System, method and apparatus for radially-movable line termination system for a riser string on a drilling rig
摘要 A line termination assembly for a riser string has a ring adapter mounted to a slip joint and a ring body mounted on top of the ring adapter. The ring adapter radially aligns with the ring body, which forms an inner diameter for receiving the slip joint. The ring body also has a discontinuity for radial access to the inner diameter, such that the ring body is circumferentially discontinuous. The discontinuity defines a chord dimension that exceeds the outer diameter of the slip joint, such that the slip joint may move radially through the discontinuity and into the inner diameter during assembly and disassembly of the system. Fluid bearings and tension rings are mounted to the slip joint and are axially spaced apart from the ring adapter and the ring body.
