After the Deepwater Horizon, we faced a problem.  How to cleanup the oil?


For example, after the Deepwater Horizon, oil skimmer technology only recovered 2-4% of the oil released from the wellhead.  [1]  The basic problem is that existing oil recovery technology struggles on the open ocean, with large waves.  


Extreme Spill Technology

Extreme spill technology (EST) developed a new approach to oil recovery.  The image below shows the EST concept.  The process relies on the natural buoyancy of oil.  The oil skims along the bottom of the hull, until it reaches the recovery tower.  Vacuum pumps raise water level into the tower, and the oil floats up with it.  Natural buoyancy keeps the oil at the top of the tower, where pumps can safely extract it.

EST Concept of Operation

EST Concept of Operation



This patented technology offers many new advantages.

  1. No external moving parts
  2. Operation in up to seastate 5
  3. Crew stay separated from the hazardous oil
  4. Operation in ice possible
  5. Nothing to damage from ice conditions
  6. Can be scaled to multiple vessel sizes
  7. Capable of recovering large quantities of oil.


This new technology works best for certain types of hullforms:  catamarans, trimarans, and barges.  They allow the hull bottom to skim near the water surface.  Combine that with the requirement for a moonpool to integrate with the oil collection tower, and retrofitting this technology to existing monohull vessels will be challenging.

EST Testing at Ohmset

EST had their technology tested at Ohmsett, which is the national testing laboratory for oil spill response technology.  The tests were favorable.  Anyone can have a bright idea.  But ideas that stand up to testing, now that shows promise.


Now EST is looking for investors to expand their product development.  If you may be interested in profiting from this technology, you can speak David Prior at Extreme Spill Technology.
