Abstract: A pipeline buoyancy control assembly includes a pair of anchor rods, a pair of tie-down attachment members, a pair of termination members, and a flexible endless strap having an endless loop configuration. The anchor rods are driven partially into the ground along opposite lateral sides of the pipeline. The tie-down attachment members are disposed on and mounted to upper end portions of the anchor rods with each tie-down attachment member having a tubular mounting body defining an axial passageway through which the upper end portion of one anchor rod extends and a retainer body disposed in an oblique relation and attached to the tubular mounting body. Each termination member is mounted to the upper end portion of one of the anchor rods. The endless strap has opposite portions secured to the tie-down attachment members and main portions laid over a top of and disposed in a substantially transverse relation to the pipeline and extending between and attached to the opposite portions. The retainer body of each tie-down attachment member defines an annular shoulder that overlies and encompasses one of the opposite portions of the endless strap so as to retain the endless strap in place over the top of the pipeline such that a buoyancy load of the pipeline is spread over the anchor rods and thereby reduces stress applied to the anchor rods.

Abstract translation: 管道浮力控制组件包括一对锚杆，一对固定附接构件，一对终端构件和具有无限循环构造的柔性环形带。 锚杆沿着管道的相对侧面被部分地驱动到地面中。 固定连接构件设置在锚杆的上端部并且安装到锚杆的上端部，每个固定连接构件具有限定轴向通道的管状安装体，一个锚杆的上端部分穿过该轴向通道延伸， 以倾斜关系设置并附接到管状安装体。 每个终端构件安装到一个锚杆的上端部。 无端带具有相对的部分，其固定到固定连接构件和主要部分，该部分布置在与管道基本上横向相对于管道的顶部并且基本上横向地相对于管道延伸并且在相对部分之间延伸。 每个系固固定构件的保持器主体限定了环形肩部，其覆盖并包围环形带的相对部分中的一个，以便将环形带保持在管道的顶部上的适当位置，使得管道的浮力负载 分布在锚杆上，从而减少施加在锚杆上的应力。
