OSRR-493-Understanding Oil Spill Dispersants: Efficacy and Effects

The project is a JIP with many agencies involved in updating this document. This document is the 1989 National Research Council's Using Oil Spill Dispersants on the Sea. Agencies in this JIP are MMS, NOAA, API, and US Coast Guard. Review and evaluate existing information regarding the efficacy and effects of dispersants as an oil spill response technique. Focus will be on understanding the limitations imposed by the various methods used in these studies and to recommend steps that should be taken on effects of dispersed oil on freshwater, estuarine, and marine environments.

OSRR-506-Analysis of IFO-180 and IFO-380 Oil Properties for Dispersant Window of Opportunity

This project will extend the work to complete property analyses on IFO-180 and IFO-380 fuel oils used in the June 2003 UK field trials and in the Ohmsett dispersant effectiveness experiments completed in the fall of 2003.

Tasks to be completed:

Conduct detailed oil property analyses on IFO-180 and IFO-380 fuel oils;
Write a technical report, scientific paper and powerpoint presentation that incorporate results from all analyses (SL Ross and COOGER laboratory maintained by the Canadian Department of Fisheries and Oceans) on the results of this research project.

OSRR-507-Correlating Results of Ohmsett Dispersant Test with At-Sea Trials: Workshop to Coordinate Publications and Prioritize Follow-up Research

The goal of this project was to coordinate the publications of results of the 2003 MMS-sponsored Correlating Results of Ohmsett Dispersant Tests with Identical At-Sea Trials study by SL Ross and A. Lewis 2004. The results of the other spin-off projects were aimed at correlating results of other dispersant effectiveness testing procedures with results of the June 2003 UK at-sea trials, and identify, plan and coordinate follow-up dispersant effectiveness experiments at Ohmsett.

OSRR-347-Emulsions Formed at Sea and in Test Tanks

This project will evaluate the tendency of oils to emulsify at sea into unstable, meso-stable, or stable emulsions. Until now there were only laboratory scale tests of emulsification and some analysis of emulsions collected at sea during clean up operations. The proposed work will extend the laboratory work into the Ohmsett tank and evaluate the factors that affect emulsification, such as oil slick thickness and wave energy in a controlled, reproducible environment like Ohmsett.

OSRR-349-Technology Assessment of the Use of Dispersants on Spills from MMS-Regulated OCS Facilities

The objective was to conduct an assessment of the operational and environmental factors associated with using chemical dispersants to treat oil spills from MMS-regulated OCS facilities. The report for the Gulf of Mexico was received in December 2000.

OSRR-114-Field Evaluation of Oil Spill Chemical Additives

The Minerals Management Service and the Conservation and Protection Agency, Environment Canada, have evaluated two new oil spill chemical additives during a series of intentional oil spills off the Canadian coast during September 1987. One chemical agent modified the visco-elastic properties of the spilled oil to enhance its recoverability using conventional mechanical techniques. The second chemical agent inhibited the formation of oil-water emulsions which are not readily captured using existing recovery techniques.

OSRR-160-Study of Oil Spill Chemical Treating Agents

This is a Joint Industry Project (JIP) between MMS and Environment Canada to: (1) develop tests for oil spill chemical treating agents and apply these lessons to develop more effective and improved products; (2) to test commercial products for efficacy and toxicity; (3) to test oil spill dispersants to understand effectiveness and how they might be improved; and (4) to test new product ideas.

OSRR-298-Testing at Ohmsett to Determine Optimum Times to Decant to Temporary Storage Devices

The Objective of this study is to conduct full-scale tests of recovered oil/emulsion/water separation rates at OHMSETT in order to predict the optimum time for decanting separated water in temporary storage devices.
