ENGINEERED WEAK POINT FOR RISER SYSTEMS

A joint assembly allows a riser system to have a weak point that can fail at a known location and tension value without reducing the riser pressure containment capacity. The joint assembly includes a standard riser pipe machined to remove material, for example, to form a groove. The joint assembly also comprises means for restoring pressure capacity. For example, the means for restoring pressure capacity include a combination of a thick-bodied clamp and a split insert ring. The split insert ring can bridge between the groove and the clamp, at least partially transferring the pressure load contained inside the machined pipe to the clamp.
