Device for skimming oil from the surface of water

Abstract

The dock vessel has the tow compartment for placement of tug-boats, and technological compartment. The technological compartment is made as a hangar at the bottom of which a central channel is located, along its upper boundaries, the rack-ledges with symmetrical location to the right and left, toward the hull, are placed on which the technological equipment for the water-oil emulsion treatment is placed. Between the dock-vessel hull walls and side walls of the central channel, the containers for collection of the emulsified oil are placed. The central channel of the technological compartment is equipped with, at least, two bulkheads in which, the hermetically pluggable openings located at different levels are made. The floating boom is made as the sectional net sleeve filled with elastic porous adsorbent and provided with positive buoyancy in the top edge of doubled net forming the net sleeve and negative buoyancy at its lower edge.

What is claimed is: 
     
         1 . A device for containment and skimming of oil and oil products on the sea comprising:
 an oil spill recovery vessel with means for pumping out oil, the oil spill recovery vessel being made as a dock vessel having the hull with decks and a double bottom, the hull having an interior divided into:
 a tow compartment situated in the after-part of the dock vessel comprises a channel framed by its walls, and two on-board hangars comprising gates and bulkheads, wherein a width of an on-board hangar is no less than that of a tug-boat and a length of an on-board hangar is no less than that of at least one tug-boat; and 
 a technological compartment made as a hangar and defied by a ceiling, side and end walls, the technological compartment comprising:
 a central channel and a plurality of rack-ledges situated to the right and left along upper boundaries of the central channel, the central channel of the technological compartment comprising at least two bulkheads with hermetically pluggable openings located at different levels, wherein the level of placing the hermetically pluggable openings in the bulkheads decreases from aft to fore; and 
 containers connected with the technological compartment and disposed between the walls of the dock-vessel and side walls of the central channel; 
 
   a guard boom coupled at one end to tug boats and made as a sectional net sleeve filled with elastic porous adsorbent and provided with positive buoyancy at a top edge of the net sleeve and negative buoyancy at a lower edge of the net sleeve; and   at least two drums with branners.   
     
     
         2 . The device as defined in  claim 1 , wherein the drums with the branners are located in the after-part of the dock vessel. 
     
     
         3 . The device as defined in  claim 1 , wherein the sectional net sleeve is detachable. 
     
     
         4 . The device as defined in  claim 1 , wherein sections of the sectional net sleeve have a different height and wherein the sections of greater heights are situated closer to the dock vessel during reeling out. 
     
     
         5 . The device as defined in  claim 1 , wherein at least one ventilation shaft is placed in a hangar ceiling 
     
     
         6 . The device as defined in  claim 1 , wherein the top edge of the sectional net sleeve, formed when the net sleeve is folded, comprises additional buoyancies.
