Report on dispersant testing under realistic conditions – Task 2 Design and Conduct Meso-Scale Tank Tests

The objective of the inter‐basin calibration study was to determine consistent test protocols and natural energy conditions as a start of Task 2. Dispersant effectiveness of one oil-dispersant combination has been performed using the pre-weathered Norwegian crude oil Grane and Corexit 9500 as the dispersant. Three different energy conditions (low, medium, high) were established.  Triplicate dispersant effectiveness tests have been conducted at each energy condition.
