Abstract
An articulated stinger attachable to a pipelaying vessel and constructed of a plurality of elongated multi-leg segments arranged in end-to-end relationship and interconnected by flexible joints. Each flexible joint is comprised of at least three components: two sockets, each in abutting ends of the multi-leg segments, and a socket-filling member. The stinger may be arranged inclined to the horizontal as in conventional pipelaying practice, or vertically for J-method pipelaying. A resilient element may be carried within the sockets to yieldably restrain relative movement between the socket and the socket-filling member.
