When studying or selecting Drilling Riser, you may want to refer to API-16Q and API-16F, and NACE specifications and as outlined in the list of specifications and design requirements. API-16F should govern for conventional weld-on drilling riser connectors. Conventional drilling connectors maybe of bolted flange, dog, or bayonet type connections. If heavy mud is in the hole, pressure test will be limited.
Riser collapse resistance should be considered and determined for the riser design using API-16Q and API-5C3.
