Claims26
A method of skimming oil and the like from the surface of a body of water utilizing a vessel having a hull having a bow, a stern having an elongate substantially horizontal slot extending across a portion thereof, side walls, a bottom, a deck, a spill suction tunnel, tunnel pump means, a collection tank, collection tank flap means located in the bottom of the collection tank and extensible into the spill suction tunnel, collection tank pump means, secondary oil recovery means, tertiary oil recovery means and oil boom means thereon, said method comprising the steps of:
- deploying the oil boom means on said vessel in said body of water;
- releasably securing oil boom means to the stern of said vessel;
- towing said vessel by the stern thereof into said oil and the like by the oil boom means;
- confining said oil and the like between the oil boom means thereby collecting said oil and the like adjacent the elongate substantially horizontal slot in the stern of said vessel;
- flowing said oil and the like and a portion of the water of said body of water underlying said oil and the like into the spill suction tunnel;
- flowing said oil and the like and an amount of water from said body of water which was flowed into the suction tunnel into the collection tank;
- separating said oil and the like from the water in the collection tank utilizing the secondary oil recovery means;
- and
- separating said oil and the like from substantially any remaining water contained therein utilizing the tertiary oil recovery means after the separation of said oil and the like from the water in the collection tank utilizing the secondary oil recovery means.

- confining said oil and the like between the oil boom means thereby collecting said oil and the like adjacent the elongate substantially horizontal slot in the stern of said vessel;
- flowing said oil and the like and a portion of the water of said body of water underlying said oil and the like into the spill suction tunnel utilizing the tunnel pump means;
- extending the collection tank flap means into the spill suction tunnel;
- flowing said oil and the like and an amount of water from said body of wateer which was flowed into the spill suction tunnel through the collection tank flap means into the collection tank;
- separating said oil and the like from a substantial portion of the water which was flowed into the collection tank therewith utilizing the secondary oil recovery means;
- flowing water from said body of water in the collection tank from said vessel into said body of water utilizing the collection tank pump means;
- and
- separating said oil and the like from substantially any remaining water contained therein utilizing the tertiary oil recovery means after the separation of said oil and the like from the water in the collection tank utilizing the secondary oil recovery means.
