Dispersant Testing Under Realistic Conditions

Research Report

REPORT ON DISPERSANT TESTING UNDER REALISTIC CONDITIONS – KEY COMPONENT 1 STATE OF THE KNOWLEDGE REVIEW

The report is a review of the literature on previous testing of dispersant effectiveness under Arctic conditions. The report details prior research which tell us that dispersants can work in the Arctic given the appropriate conditions, it also confirms that we have a significant amount of information describing when we can use dispersants. The future work will refine this even more.

TEST TANK INTER‐CALIBRATION FOR DISPERSANT EFFICIENCY REPORT – KEY COMPONENT 2 BASIN TESTS IN ICE-CONDITIONS

The objective of the inter‐basin calibration study was to determine consistent test protocols and natural energy conditions as a start of Key Component 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 were conducted at each energy condition.

REPORT ON DISPERSANT USE IN ICE-AFFECTED WATERS:  STATUS OF REGULATIONS AND OUTREACH OPPORTUNITIES – KEY COMPONENT 5 REGULATORY REQUIREMENTS AND PERMITTING PROCESSES

The report is a summary of dispersant use regulations in ice-prone countries, a discussion of the potential obstacles to achieving permission to conduct dispersant operation in ice-prone regions, and a strategy to address obstacles. Based upon this review of the current regulatory environment and except for the UK and the US, it is suggested that obtaining blanket nationwide pre-approval for dispersants from all ice-affected countries is probably unlikely. The report outlines the potential to help countries with oil and gas activities in ice-affected waters appreciate the potential benefit of an expedited process to approve the use of dispersants.
