RPSEA's Ultra-Deepwater Technical Advisory Committees (TAC) focus on a particular ultra-deepwater technology area. The role of the TACs, with representation from subject matter experts who study and apply ultra-deepwater technologies in real field situations, is to identify current technology gaps and define the specific R&D efforts needed to address these gaps. As such, the TACs provide a bottom-up, end-user-driven program.

There are a total of six UDW TACs.

The UDW TACs are open to the public

The DCI TAC's goal is to improve deepwater drilling operations.
