| abstract | A mechanical joint assembly (600, 610, 700, 800, 900) for a steel catenary riser (400) (SCR). The lower section of the mechanical joint assembly (600, 610, 700, 800, 900) is comprised of steel or alternate high strength components, rather than elastomers to absorb the high loads and increase life of the unit. The lower mechanical joint assembly provides for reduction of bending moments and resulting fatigue stresses at the SCR top by removing resistance to movement in all angular directions, providing increased construction tolerances for the pipeline approach corridor. Pipeline approach angle increase is accommodated by providing dual orthogonal trunnions (635, 681) in addition to an axial swivel. The upper mechanical joint assembly, acting without riser tension loads, allows for the use of either flexible high-pressure pipe or swivel arrangements (700) to accommodate angular flexure before the rigid deck piping (500). The mechanical joint assembly provides for upstream (900) and downstream (800) valving for safety and maintenance without decreasing the fatigue life of SCR's. |
