    摘要： New joint compensator and systems and methods of their use have been invented which, in one aspect are useful for compensating for the weight of a first joint and at least one subsequent joint, the first joint to be supported above the at least one subsequent joint, the joint compensator in one aspect having a body interconnectible between the first joint and moving apparatus, the body including supporting apparatus for supporting the first joint above the at least one subsequent joints and for providing support of the first joint as it moves with respect to the at least one subsequent joint, the supporting apparatus compensating for weight of the first joint as it moves, the support apparatus for alternately supporting the first joint and then the at least one subsequent joint, the support apparatus initially adjustable to compensate for the weight of the first joint so that the support apparatus is also thereby adjusted to compensate for weight of the at least one subsequent joint.

    摘要： A torque multiplier subsea tool for setting a seal between a casing hanger and a subsea wellhead includes a mandrel having a sun gear with axial elongate teeth. An outer barrel is disposed around the mandrel forming an annulus therebetween. A planetary gear assembly is disposed in the annulus between the barrel and the sun gear to transmit to the barrel a torque which is higher in magnitude than that applied to the mandrel. A connector body disposed around the mandrel, below the planetary gear assembly, includes radially movable dogs for engaging the casing hanger. The barrel engages the sealing assembly and transmits the increased torque thereto to advance the sealing assembly downwards and to set the seal. The mandrel advances downwards with the sealing assembly and releases the dogs from the casing hanger. An emergency release mechanism is provided to advance the mandrel downwards to release the dogs in the event such downward movement is prevented during normal seal setting operation.

    摘要翻译： 用于设置套管悬挂器和海底井口之间的密封的扭矩倍增器海底工具包括具有轴向细长齿的太阳齿轮的心轴。 外筒围绕心轴设置在它们之间形成环形空间。 行星齿轮组件设置在机筒和太阳齿轮之间的环形空间中，以向筒体传递与施加到心轴上的扭矩大的扭矩。 设置在心轴周围的行星齿轮组件下方的连接器主体包括用于接合壳体悬挂器的可径向移动的卡爪。 筒体与密封组件接合并将增大的扭矩传递到其上以使密封组件向下推动并设置密封。 芯轴随着密封组件向下推进，并从套管吊架上释放狗。 提供紧急释放机构以在正常密封设置操作期间防止这种向下移动的情况下向前推动心轴向下释放狗。
