3. Completion of American Underpressure System (AUPS) Test Program: Final Report to the Office of Naval Research (ONR) 2004.
The U.S. Congressional Oil Pollution Act of 1990 allowed for the evaluation and approval of alternatives that can be determined to have equal or better performance than the double hull in protecting the marine environment.
AUPS is an active inert gas controlled system utilizing a vacuum technique, which drastically reduces or totally prevents spillage from a rupture to the hull, accidentally or from enemy action. It has been tested in full scale on the USNS Shoshone also under a contract from the ONR under Congressional authorization.
The EXECUTIVE SUMMARY of the Final Report, prepared at the completion of the comprehensive analysis of the tests and risk-based design, is shown here-in.
