Dispersants are chemicals designed to change the black oil that is floating as a layer on the sea surface, into a plume of small droplets that move into the water column to a depth of 5 – 10m. This cloud of oil will quickly be diluted to a low concentration where it will be naturally degraded reducing its impact to the environment by decreasing the:

  • Persistence of the oil in the environment
  • Risk of oil impacting shoreline
  • Volume of waste created.
