  7. Objective and Deliverables Lab measurements OBJECTIVE: • Develop field monitoring methods and technologies to measure the effectiveness of dispersants for subsea applications using ultrasonic based technologies to measure the oil particulate size. DELIVERABLES: • Kick Off Meeting Summary • Quarterly Progress Reports • Final Report Ohmsett Measurements in 2012 Commercial Sonar

  8. Tasks Task 1. Laboratory Measurements • Measure ultrasonic scattering response from oil droplets • Dispersion Types (Corexit 9500, Corexit 9527 and Agma DR 379) • Crude types, sediment, and temperature • Precision ultrasonic instruments • Commercial sonar and marine acoustic instruments Task 2. Data Analysis • Benchmark ultrasonic measurements of droplet size with LISST and visual measurements/image analysis. Task 3. Theory and Modeling • Literature Review • Compare the theory with the experiment. Task 4. Algorithm Development • Develop the droplet sizing algorithm from ultrasonic/acoustic data Task 5. Testing at Ohmsett • Study dispersion effectiveness and robustness of measurement methods using precision ultrasonic, sonar, and marine acoustics instruments. Task 6. Reporting and Project Management • Quarterly and final reports
