Since its inception in 1992, DeepStar has progressed from a dollar 500,000 paper study of the feasibility of extended reach subsea tiebacks to a focus on developing generic deepwater technology. A large component of the Phase III program involves testing. The emphasis on testing has continued in Phase IV, which began in January 1998. DeepStar committees focus on regulatory interface, flow assurance, subsea equipment, vessels, mooring and risers, drilling and completions and reservoir engineering. This special session will cover highlights of activities recently completed, provide an overview of the present dollar 12 million Phase IV program and project DeepStar's future direction. The benefits of cooperative research efforts continue to be reaped. Illustrative examples of DeepStar technology include: novel pigging and instrumentation, flow assurance instrumentation, prediction of hydrate plug movement, subsea intervention, dynamic steel tube umbilicals, composite drilling risers and methods to alleviate shallow water flows. Phase IV continues to include a significant component of field-scale testing. This will range from four significant flow assurance tests, to deployment of an electrically heated pipeline system to be tested in an ocean environment.
