摘要 |
Apparatus for laying a pipeline of large diameter on a deep sea-bed without kinking or excessive bending includes a floating vessel having a discharge track sloping downwardly toward the stern to support the outer end of a pipeline for sliding movement and mechanism for imparting tension to a pipeline is mounted on the discharge track. A stinger, adapted to slidingly support a pipeline as it is being laid, is pivotably connected to the discharge end of the track and is formed from articulated ramp segments, each buoyantly supported independently of the others so that its depth in the water may be regulated, whereby the stinger may be caused to extend downwardly from the stern of the vessel along a predetermined slope. |
