ABSTRACT:
A continuous marine pipe laying system utilizes two rollers to overbend and straighten pipe as it is unwound from a reel. A support arm is pivotally connected to the axis of rotation of said reel and first and second roller arms are pivotally connected to the support arm at a point spaced from said axis of rotation. During use, the first roller is positioned at a point adjacent the pipe substantially opposite the departure point of the pipe from the reel. The second roller is spaced from the first roller so as to create an appropriate overbend to straighten the pipe and is maintained at that spacing as successive layers of pipe are unwound from the reel.
