The scope of the contract was to complete the test program of the American Under pressure System (AUPS). AUPS, when installed in a tanker, significantly reduces and in some cases eliminates the spilling of oil when a tanker is collided or grounded. A slight underpressure in the ullage (the space between the oil surface and the tank top) creates a hydrostatic balance with the sea surface. The scope of work included the control system design and simulation, a final installation design in 3 sizes of tankers, probabilistic outflow analyses of 8 notional tankers plus the above three tankers and extensive responses to the US Coast Guard requirements for rule making changes. The final report includes an economic analysis for the smallest (70,000 dwt) and largest (300,000 dwt) tankers with the AUPS installation. The probabilistic outflow statistics were developed by the International Maritime Organization and included the probability of all types of collision and grounding ruptures. This Final Report provides the mathematic modeling of the control system, the simulations of the various events and responses, risk assessment, vapor generation and safety, structural analyses and dollars per barrel saved with AUPS.
