The function of a ball joint in a marine riser system is to allow angular deflection between the riser and the vessel or the subsea wellhead, accommodating relative movement and reducing bending stresses in the riser. A marine riser is a conduit that connects a surface vessel to a subsea wellhead, providing a pathway for drilling fluids, tools, and production fluids. The vessel and the wellhead are subject to different motions due to wave action, currents, and tidal variations. Without a ball joint, th....
