    • Sections of pipe for an underwater pipeline are laid by first positioning a support frame on the underwater terrain generally about the position for a section of pipe and then lowering a longitudinal pipe support and a section of pipe into engagement with the support frame. The position of the longitudinal pipe support on the support frame can be adjusted for proper positioning of the section of pipe with previously laid pipe. After a section of pipe is laid and supported by backfill, the underwater support frame is moved to the position for the next section of pipe. The support frame includes first and second transverse members each having a saddle for receiving a seat portion of the longitudinal pipe support. The saddles are moveable along the transverse members for adjusting the position of a section of pipe, and one of the transverse members is moveable. The longitudinal pipe support is moveable on a roller in the saddle on the fixed transverse member. The support frame includes a plurality of extendable vertical legs for engaging the underwater terrain.
    • 通过首先将水平地面上的支撑框架定位在大体上围绕一段管道的位置,然后将纵向管道支撑件和管道的一部分与支撑框架接合来放置用于水下管道的管道的部分。 可以调节支撑框架上的纵向支撑件的位置,以便正确定位管道与预先铺设的管道。 在回填一段管道放置并支撑后,水下支撑架移动到下一段管道的位置。 支撑框架包括第一和第二横向构件,每个横向构件具有用于容纳纵向管道支撑件的座部的鞍座。 鞍座可以沿着横向构件移动,以调节管道的一部分的位置,并且横向构件中的一个可移动。 纵向管支撑件可在固定横向构件上的鞍座中的辊上移动。 支撑框架包括用于接合水下地形的多个可延伸的垂直腿。
