Oil Dispersant Application System Frequently Asked Questions
What is an oil spill dispersant?
“Dispersants” as they are known generically are low toxicity chemicals that are used to break up oil on the surface of the water and promote natural degradation. They are a tool used alongside mechanical recovery and in-situ burning.
When are dispersants used?
Dispersant is typically used in large scale incidents offshore when other means are limited. Responders will go through a net environmental benefit analysis.
Where is it used?
Dispersant is not typically used in shallow or inland waters.
How is it applied?
Dispersant has to be sprayed in the correct manner to ensure effectiveness. It may be sprayed from aircraft or ships.
Does dispersant usage have to be approved?
Yes. The use of oil dispersants is regulated in most countries. Not only does the use need to be approved, the chemical itself has to undergo testing for toxicity and effectiveness.
What dispersant spray systems does Elastec offer?
We have three different systems, Elaspray is a conventional pump and arm setup, with arms that are mounted to the side of a ship. The Neatsweep is more precise as oil is funneled to a channel where the oil dispersant is applied ( dosage automatically adjusts to the speed of the vessel ), and the Boom Vane Spray (BVS). The BVS system enables vessels to get closer to shore with a wider swath than arms.
