ABSTRACT:
An improved articulated stinger for laying pipe at the bottom of a body of water is disclosed. The first structural support for the pipe, after it leaves the vessel, is provided at a substantial distance from the vessel. A long, nonarticulated stinger link, attached to the vessel, does not engage the pipe and serves to position a buoyant stinger means beneath an effective wave action water depth. In addition, the long length of the stinger link separates the buoyant stinger means (and first pipeline support) from the vessel by a distance sufficient to substantially decouple vessel motion from the buoyant stinger means. There results through this arrangement significantly less banging between the pipe and the stinger assembly.
