 Oil Recovery Vessel - ORV

Oil spills at sea cause serious damage to marine life as well as coastal areas and often demand huge sums of investment to clean up the affected areas. It is a time consuming and labour intensive mission, that needs to be set out each time an (oil) tanker looses oil. Its success depends on the speed of the spills and the wind effect. Usually, only parts are cleaned while the remainder is washed ashore.


Oil Recovery Vessel in operation

By designing a high seaworthy catamaran type of vessel with on-board cleaning and out-board oil slick storing facilities, Van den Noort Innovations BV has succeeded to bring about a break-through concept to act significantly faster and much more effectively.

The ORV is especially developed for the purpose to substantially enhance speed and capacity to recover oil spills from an oil disaster at sea. With a cruising speed of 25 30 knots it responds much faster to the disaster scene and by its concept this type of vessel is to collect 500 tons of slick with an average speed of 5 knots per hour. No intermediate slick discharge in nearest port is required as slick is pumped in separate floating rubber containers during cleaning activity as long as it takes. Note: this invention has received the Innovation 2000 Award.

Features:

  • Fast response to the scene of the disaster, with a speed of 25 - 30 knots per hour

  • A capacity to collect and separate 500 tons of oil slick per hour, with an average speed of 5 knots.

  • No intermediate slick discharge at nearest port of call, by utilizing out-board floating rubber containers to be tugged away after job completion

  • Tremendous time saving factor, while disaster impact is much more contained

  • Substantial less damage to the environment

  • Capability to even operate in rougher seas.

Principle of the Oil Recovery Vessel

Oil recovery by brushes between the bows

Our concept utilizes 2 wide rotating nylon brushes fixed between the bows of a catamaran vessel. The brushes rotate in opposite direction to the incoming water flow. The oil slick adheres to the rotating brushes to meet a scraper at the back side of the vessel removing the slick from the brushes. The slick is collected in a large reservoir. Further separation is processed in the reservoir as a result from the difference in density between oil and water. A draining valve at the bottom of the reservoir allows the water to be discharged. Next, the slick is pumped into floating rubber containers not demanding on-board space. The rubber containers will be collected after completing the job and tugged away to the nearest port. As the vessel does not need to return to the port to discharge the waste, its required tonnage is minimum. While scouring the sea, the speed of the vessel is determined by the thickness of the slick (approximately 5 to 8 knots).
