Abstract
Abstract A method of transporting oil by vessel which includes discharging an oil cargo at a destination and refilling the vessel with a water ballast, transporting the vessel to an oil supply area, discharging only the water ballast at the oil supply area while retaining any oil-water mixture within the vessel. Apparatus is provided which automatically maintains delivery of only a single density fluid by operating only within the fluid to be delivered and ceasing to operate when in a different fluid. In an alternative embodiment, conduits are fixed in the vessel with their ends a predetermined distance apart to withdraw selectively different density fluids by pump means selectively controlled by a float member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
An apparatus for segregated delivery of fluids of different density, said apparatus comprising: a first conduit including a first end; a second conduit including a first end; selectively operable pump means operatively connected to said first conduit and said second conduit for selectively transferring fluid through said first conduit and said second conduit; and sensing means responsive to the level of fluid of a predetermined density for causing said pump means to operate to selectively transfer fluid through said first conduit and said second conduit; and wherein said sensing means includes a first float means in an operable relationship with said first end of said first conduit for positioning said first end of said first conduit within a first fluid; first sensing means for preventing said fluid transfer through said first conduit in response to said first conduit first end moving out of said first fluid; second float means in an operable relationship with said first end of said second conduit for positioning said first end of said second conduit within a second fluid; and second sensing means for preventing said fluid transfer through said second conduit in response to said second conduit first end moving out of said second fluid.
Claim 2
Independent Claim
201 words
An apparatus for segregated delivery of fluids of different density, said apparatus comprising: a first conduit including a first end; a second conduit including a first end; selectively operable pump means operatively connected to said first conduit and said second conduit for selectively transferring fluid through said first conduit and said second conduit; and sensing means responsive to the level of fluid of a predetermined density for causing said pump means to operate to selectively transfer fluid through said first conduit and said second conduit; and wherein said sensing means includes a first float means in an operable relationship with said first end of said first conduit for positioning said first end of said first conduit within a first fluid; first sensing means for preventing said fluid transfer through said first conduit in response to said first conduit first end moving out of said first fluid; second float means in an operable relationship with said first end of said second conduit for positioning said first end of said second conduit within a second fluid; and second sensing means for preventing said fluid transfer through said second conduit in response to said second conduit first end moving out of said second fluid.
Claim 3
Dependent Claim
54 words
The apparatus as set forth in claim 1 wherein said pump means includes first pump means in an operable relationship with said first conduit for transferring said first fluid through said first conduit and second pump means in an operable relationship with said second conduit for transferring said second fluid through said second conduit.
Claim 4
Dependent Claim
28 words
The apparatus of claim 1 wherein said first and said second sensing means includes means for preventing said fluid transfer in response to a change in fluid viscosity.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1 wherein said sensing means includes means for preventing said fluid transfer in response to a change in fluid density.
Claim 6
Dependent Claim
23 words
The apparatus of claim 4 wherein said sensing means is further characterized as including means for sensing the horizontal attitude of said float.
Claim 7
Dependent Claim
15 words
The apparatus of claim 1 wherein said float means is adapted to be selectively buoyant.
