摘要： The present invention generally relates to an apparatus and method for compensating a landing string due to movement of a floating rig platform. In one aspect, a compensation system (100) for use with a landing string is provided. The compensation system includes a slip joint (115) member attachable to the landing string, the slip joint member having an upper portion and a lower portion. The compensation system further includes a first lock assembly (140) configured to connect the upper portion of the slip joint member to a floating rig. Additionally, the compensation system includes a second lock assembly configured to connect the lower portion of the slip joint member to a riser (40) disposed below the floating rig. In another aspect, a method for compensating a landing string due to movement of a floating rig is provided.

摘要： In one, embodiment, a top drive system (200) includes a quill (214); a motor (201) operable to rotate the quill; a gripper (275) operable to engage a joint of casing; a connector (300) bi-directionally rotationally coupled to the quill and the gripper and longitudinally coupled to the gripper; and a compensator longitudinally coupled to the quill and the connector. The compensator is operable to allow relative longitudinal movement between the connector and- the quill.
