Vessel for collecting and separating oil/water in a marine environment using submerged internal collection, and separation

Claim 2

A marine vessel having sides, for collecting and separating spilled oil in a marine environment having a sea level surface comprising: (a) a floating vessel having an enlarged interior collection chamber for receiving an oil/water mixture from the adjacent sea surface via a separator inlet at the bottom of the collection chamber and the chamber extending laterally to the sides of the vessel; (b) at least a portion of the collection chamber extending down to an elevation below the sea surface during use; (c) an oil/water separator contained within the vessel collection chamber and surrounded by the oil/water mixture contained therewithin, and positioned at least partially below the sea level surface during use so that oil and water can be separated by the separator below the sea level surface by the mechanical action of the oil attempting to rise to the sea level surface from a lowermost position at the inlet and upwardly the sea surface level, the separator comprising a plurality of vertically spaced members with surfaces that allow rising oil to accumulate thereon during separation and an oil inlet at the lower end portion of the separator for adding oil to the separator; (d) surface intake means for transmitting an oil an water mixture from the adjacent sea surface to the separator inlet; and (e) a flowline for communicating oil from the intake to the separator at the oil inlet portion thereof.

Claim 3

The apparatus of claim 1, wherein the intake means comprises a catch basin having an outlet with an elevation below the sea level surface during use.

Claim 4

The apparatus of claim 1, wherein the separator comprises a closed wall separator having multiple vertically spaced plates.

Claim 5

The apparatus of claim 3, wherein at least some of the plates are angled with respect to horizontal.

Claim 6

The apparatus of claim 4, wherein at least some of the plates are parallel to each other.

Claim 7

The apparatus of claim 1, further comprising means for determining the level of oil.

Claim 8

A marine vessel for collecting and separating spilled oil in a marine environment having a sea level surface comprising: (a) a floating vessel having an interior collection chamber for receiving an oil/water mixture from the adjacent sea surface; (b) at least a portion of the collection chamber extending to an elevation below the sea surface during use; (c) at least one oil/water separator contained within the vessel collection chamber, and positioned at least partially below the sea level surface during use so that oil and water can be separated by the separator below the sea level surface by the mechanical action of the oil attempting to rise to the sea level surface, the separator comprising a plurality of vertically spaced members with surfaces that allow rising oil to accumulate thereon during separation and an oil inlet at the lower end portion of the separator for adding oil to the separator; (d) at least one intake for collecting an oil and water mixture from the adjacent sea surface; (e) a flowline for communicating oil from the intake to the separator at the oil inlet portion thereof; and (f) wherein the intake includes a boom extending outwardly from the vessel for channeling oil to the intake as the vessel is moved.

Claim 9

A marine vessel for collecting and separating spilled oil in a marine environment having a sea level surface comprising: (a) a floating vessel having an interior collection chamber for receiving an oil/water mixture from the adjacent sea surface; (b) at least a portion of the collection chamber extending to an elevation below the sea surface during use; (c) at least one oil/water separator contained within the vessel collection chamber, and positioned at least partially below the sea level surface during use so that oil and water can be separated by the separator below the sea level surface by the mechanical action of the oil attempting to rise to the sea level surface, the separator comprising a plurality of vertically spaced members with surfaces that allow rising oil to accumulate thereon during separation and an oil inlet at the lower end portion of the separator for adding oil to the separator; (d) at least one intake for collecting an oil and water mixture from the adjacent sea surface; (e) a flowline for communicating oil from the intake to the separator at the oil inlet portion thereof; and (f) wherein the intake includes a boom extending outwardly from the vessel for channeling oil to the intake as the vessel is moved.

Claim 10

The apparatus of claim 7, wherein the vessel is self-propelled.

Claim 11

A marine vessel for collecting and separating spilled oil in a marine environment having a sea level surface comprising: (a) a floating vessel having an interior collection chamber for receiving an oil/water mixture from the adjacent sea surface; (b) at least a portion of the collection chamber extending to an elevation below the sea surface during use; (c) at least one oil/water separator contained within the vessel collection chamber, and positioned at least partially below the sea level surface during use so that oil and water can be separated by the separator below the sea level surface by the mechanical action of the oil attempting to rise to the sea level surface, the separator comprising a plurality of vertically spaced members with surfaces that allow rising oil to accumulate thereon during separation and an oil inlet at the lower end portion of the separator for adding oil to the separator; (d) at least one intake for collecting an oil and water mixture from the adjacent sea surface; (e) a flowline for communicating oil from the intake to the separator at the oil nlet portion thereof; and (f) wherein the separator comprises a closed wall structure having a bottom, and side walls defining an oil holding interior, and the side walls include at least one water outlet, the oil inlet communicating with the bottom, and the interior having said plurality of vertically spaced members comprising multiple transverse, vertically spaced plate members with surfaces for catching and accumulating oil rising within the interior that has been introduced thereinto via the oil inlet.

Claim 12

A marine vessel for collecting and separating spilled oil in a marine environment having a sea level surface comprising: (a) a floating vessel having an interior collection chamber for receiving an oil/water mixture from the adjacent sea surface; (b) at least a portion of the collection chamber extending to an elevation below the sea surface during use; (c) at least one oil/water separator contained within the vessel collection chamber, and positioned at least partially below the sea level surface during use so that oil and water can be separated by the separator below the sea level surface by the mechanical action of the oil attempting to rise to the sea level surface, the separator comprising a plurality of vertically spaced members with surfaces that allow rising oil to accumulate thereon during separation and an oil inlet at the lower end portion of the separator for adding oil to the separator; (d) at least one intake for collecting an oil and water mixture from the adjacent sea surface; (e) a flowline for communicating oil from the intake to the separator at the oil nlet portion thereof; and (f) wherein the separator comprises a closed wall structure having a bottom, and side walls defining an oil holding interior, and the side walls include at least one water outlet, the oil inlet communicating with the bottom, and the interior having said plurality of vertically spaced members comprising multiple transverse, vertically spaced plate members with surfaces for catching and accumulating oil rising within the interior that has been introduced thereinto via the oil inlet.
