English Abstract

An oil spill cleanup system has a vessel, a separator within the vessel for separating oil and water, a pump for pumping an oil/water mixture into the separator, and one or more probes and submersibles having hoses connected to the pump, for collecting the oil/water mixture. The separator has two or more adjacent tanks, for containing the oil/water mixture. Gravity separates the oil from water in the first tank and the water is evacuated from the bottom, while the oil overflows in the second tank, having an increased oil concentration, and so on, until the concentrated oil is evacuated. A mobile oil platform is also disclosed, having a subsea well connected to a hose, which carries oil to a vessel. The vessel receives the oil and is exchangeable with an empty vessel when full. When the vessel drops the hose, floats maintain its location.


French Abstract

Un système de nettoyage pour les déversements d'hydrocarbures comportant un vaisseau, un séparateur au sein du vaisseau pour séparer les hydrocarbures et l'eau, une pompe pour le pompage du mélange hydrocarbures/eau dans le séparateur, et une ou plusieurs sondes et submersibles dotés de boyaux connectés à la pompe pour recueillir le mélange hydrocarbures/eau. Le séparateur comprend deux réservoirs ou plus pour contenir le mélange hydrocarbures/eau. La gravité sépare les hydrocarbures de l'eau dans le premier réservoir, l'eau est évacuée par le bas, tandis que les hydrocarbures débordent dans le deuxième réservoir, dont la concentration d'hydrocarbures est plus importante, et ainsi de suite, jusqu'à ce que les hydrocarbures concentrés soient évacués. Une plateforme mobile de forage pétrolier est également divulguée, et comprend un puits sous-marin connecté à un tuyau, qui transporte les hydrocarbures à un navire. Le vaisseau reçoit les hydrocarbures et peut être échangé avec un vaisseau vide lorsqu'il est rempli. Lorsque le vaisseau lâche le tuyau, des flotteurs marquent son emplacement.

CLAIMS

1. A method for oil spill cleanup comprising:
a. deploying one or more probes into the oil spill for sucking an oil and
water
mixture;
b. sucking the oil and water mixture into a separator by means of a pump on
board
of a vessel oil tanker;
c. separating by gravity the oil and water mixture using a four tank
separator,
wherein a first tank fills with the oil and water mixture, and overflows oil
into a
second tank, the second tank overflows oil into a third tank, and the third
tank
overflows oil into a fourth tank, wherein each tank separates oil from water;
and
d. evacuating the separated water.
2. The method of claim 1, wherein step a further comprises the step of
deploying one or
more submersibles into a subsea oil spill.
3. The method of claim 1, further comprising the step of controlling the one
or more
probes remotely, by way of a camera.
4. The method of claim 2, further comprising the step of controlling the one
or more
submersibles remotely, by way of a camera.
5. The method of claim 1 wherein the oil spill is contained using booms, the
booms
dragged by the one or more probes and the one or more probes operating within
the
booms.
6. The method of claim 2 wherein the one or more submersibles are directed to
a subsea
well.
7. The method of claim 1, wherein the separator is self-contained and is
movable to where
it is required.
8. The method of claim 7, wherein the separator is in a tanker truck.
9. The method of claim 7, wherein the separator is in a ship.

12


10. The method of claim 1, wherein the one or more probes comprise a
manoeuvrable
sucking tube, the method further comprising the step of manoeuvring the
sucking tube
into the greatest oil concentration.
11. The method of claim 8 wherein a remote operator performs the manoeuvring
of the
sucking tube.
12. The method of claim 1, further comprising the step of filtering the
separated water
using a mechanical filter before evacuating the separated water.
13. The method of claim 12, the separator further comprising an oil free zone,
wherein the
separated water is contained in the oil-free zone before being evacuated.
14. The method of claim 13 further comprising the step of a boat with a
driver, while in
communication with a cleanup operator, dragging a vacuum hose to the oil spill
and
sucking up the mixture.
15. A method of claim 1 wherein the separator is equipped with one or more
vacuum hose
and hose extensions to suck up the mixture and collect the oil and the gas
within the
separator.
16. The method of claim 9, wherein the ship is a tanker that is on top of an
oil carrier
cleanup vessel separating the mixture and evacuating the separated water by
gravity.
