Abstract

The present disclosure relates to a subsea catenary and a method of distributing ballast on a pipe. The subsea catenary includes a flexible pipe, and a selected amount of ballast attached to the flexible pipe, in which the ballast is distributed in a wave pattern on a sag bend of the subsea catenary. The method includes identifying a position of a sag bend in a flexible pipe of the subsea catenary, and applying ballast in a wave distribution along the subsea pipe at the identified position.
