ISO 13624-1:2009 pertains to the design, selection, operation and maintenance of marine riser systems for floating drilling operations. Its purpose is to serve as a reference for designers, for those who select system components, and for those who use and maintain this equipment. It relies on basic engineering principles and the accumulated experience of offshore operators, contractors, and manufacturers.

The marine drilling riser is best viewed as a system. It is necessary that designers, contractors, and operators realize that the individual components are recommended and selected in a manner suited to the overall performance of that system. For the purposes of ISO 13624-1:2009, a marine drilling riser system includes the tensioner system and all equipment between the top connection of the upper flex/ball joint and the bottom of wellhead conductor outer casing. It specifically excludes the diverter. Also, the applicability of ISO 13624-1:2009 is limited to operations with a subsea BOP stack deployed at the seafloor.

ISO 13624-1:2009 is directly applicable to most floating drilling operations, to special situations dealing with deepwater drilling and collapse, to the special considerations required for guidelineless drilling and to operations in cold-weather conditions and H₂S considerations.

It is important that all riser primary-load-path components addressed in this International Standard be consistent with the load classifications specified in ISO 13625.
