Phase II of the Deepstar Project was an Investigation to solve the shallow water flow problem in the Gulf of Mexico (GoM) and was supported by the Deepstar Consortium. The project encompassed a feasibility study for long conductor pile installation (by commercial hammers) down to 1,200-ft below the sea floor and resulted in a user-interactive pile driving analysis program based on the wave equation method. Phase III of the Deepstar Project, built upon the findings of Phase II and formulated procedures for deep conductor installation.  Aggie Drilling Research was subsequently retained to investigate the application of riserless drilling concepts (later known as subsea mud lift drilling) for water depths of 10,000-ft. This project included a detailed study of hydraulics for steady state and transient behavior of drilling fluids, well control, and user-interactive programming. The program developed was copyrighted (TAMU 1214, Txu775-006).
