Numerous toxicological studies have been performed on mineral and vegetable-based oils over the last decade. Mineral and vegetable-based oils display low direct toxicity because they do not contain the water soluble and multi-ringed poly-nuclear aromatic hydrocarbons typically found in petroleum-based oils. Due to their low toxicity and usage, little research has been performed on the response options available to cleanup a spill of dielectric fluids on the marine environment. In the unlikely event of a spill, how would the dielectric insulating oil be removed from our oceans and shorelines? How persistent are these oils in the marine environment?

To provide a comprehensive analysis of the possible fate and effects of spilled dielectric insulating oil, LSU and MMS will conduct a collaborative one (1) year project to provide a detailed literature review and scientific information on the characteristics, weathering behavior, and window of opportunity for using short-term response options for removal of spilled dielectric fluids in the marine environment. The goals of this project will be achieved through a series of laboratory and field-scale studies conducted at research facilities in Baton Rouge, Louisiana (LSU) and Leonardo, New Jersey (Ohmsett). The results from this project will have a direct effect on the spill response policies and decision-making of federal and state agencies when dealing with accidental releases of dielectric insulating fluids in the marine environment. Results from this study will aide planning and management personnel when designing coastal use permits for future offshore wind generation systems.

Objectives: The goals of this one (1) year scientific project are to provide detailed literature review and produce valid data and results on the characteristics, weathering behavior, and window of opportunity for using short-term response options for removal of spilled dielectric fluids in the marine environment. The goals of the proposed project will be achieved through a series of six (6) tasks:

1. An intensive literature review of US and European sources
    
2. A series of laboratory flask studies to determine weathering characteristic, product dispersibility, and accurate analytical methodology
    
3. A field study to accurately determine applicability of in-situ burning as a response tool
    
4. A laboratory flask study to measure the affects of long-term weathering and biodegradation on dielectric insulating fluid in the marine environment
    
5. A series of field studies to accurately determine capabilities/limitations of conventional response tools for removal of dielectric fluids from the marine environment
    
6. Preparation and submittal of a final draft and report to MMS

All tasks, except task No. 5, will be performed at LSU in Baton Rouge, Louisiana. Task No. 5 will be completed at the Ohmsett facility in Leonardo, New Jersey.
