Coupling capacity ratings are established to enable the grouping of coupling models according to their maximum stresses developed under specific levels of loading,regardless of manufacturer or method of make-up.This International Standard relates directly to API RP 16Q, which provides guidelines for the design, selection, and operation of the marine driling riser system as a whole. 2Normative references The following referenced documents are indispensable for the application
