Portable Rapid Test Fuel Tank Leak Detection System

摘要

The Portable Rapid Test (PRT) tank leak detection system development was conducted under the Chief of Navy's 0817 Pollution Abatement Ashore RDT&E program. Its goal was to bring Navy fuel tanks into regulatory compliance in a cost-effective manner. The PRT Leak Detection System was successfully designed and evaluated for use in 50,000 gallon fuel underground storage tanks (USTs). Using EPA mandated procedures, the PRT achieved a 0.067 gal/hr leak rate with 95% probability of detection (PD) and 5% probability of false alarm (PFA) during 3rd Party Certification Testing at the Barking Sands Pacific Missile Range fuel farm, Kauai, Hawaii. This is the best EPA approved leak rate achieved to date in industry worldwide for a 50,000 gallon in-tank system, with results in 5-hours, and is the only available system which has the dual capability for conducting a combined monthly and annual compliance test. The system allows testing at EPA standard leak rates of 0.10 gal/hr and 0.20 gal/hr with a very high PD and very low PFA. This provides a significant improvement over current methods technologically, operationally, and in short and long-term cost benefits. The final report steps through the development stages of the PRT technology including off-the-shelf component elections, development of new hardware and software, system integration, and laboratory, field and certification testing.
