Abstract: A tensioner assembly for applying tension to a tubular member, such as a riser, can include an upper latch connected to the tubular member, a platform with a bore, and a plurality of lower latch segments, each having a base that is pivotally connected to the platform. After applying tension to the tubular member, the segments pivot inward to form an annular lower latch ring having an inner diameter less than an outer diameter of the upper latch. The assembly can include a locking mechanism that prevents axial movement of the upper latch, relative to the lower latch ring, after engagement. The upper latch can self-center on the lower latch as it is moved into the latching position.

Abstract translation: 用于向管状构件（例如提升管）施加张力的张紧器组件可以包括连接到管状构件的上部闩锁，具有孔的平台和多个下部闩锁段，每个下部闩锁段具有枢转地连接到 的平台。 在向管状构件施加张力之后，节段向内枢转以形成具有小于上部闩锁的外径的内径的环形下部闩锁环。 组合件可以包括锁定机构，其在接合之后防止上闩锁相对于下闩锁环的轴向移动。 当上下闩锁移动到锁定位置时，上部闩锁可自动对准下部闩锁。
