ABSTRACT:
A method of alleviating problems with high stresses above fatigue failure levels due to vibrations modes caused by vortex shedding during the lowering and jetting-in of a large diameter surface string in deep water having a current characterized by the inclusion of a moment reducing device in the suspension conduit holding the surface string of conduit during lowering and jetting-in. Also disclosed are preferred embodiments where the moment reducing device is either a ball joint or a flex joint.
