Abstract

A flexible pipe joint achieves flexibility between pipe sections using a plurality of elastomeric pads arranged to create a spherical acting joint. The angle of the pads (and resulting radius of the sphere) can be selected to optimize the internal loads and relative motions of the mating parts. The use of the flex joints reduces bending moments in the pipe from vessel motions and current loads. Stability of the assembly may be maintained by having sufficient weight on the lower sections of the riser to resist current loads. A soft elastomeric seal minimizes fluid loss and allows relative motions of the pipe at the joint. The connector may be mated by inserting the inner pipe into the outer pipe and then rotating the pipe sections relative to each other until a stop is reached. A separate latch may be set, or automatically set, to prevent reverse rotation and unlatching.
