METHOD AND DEVICE FOR COLLECTING A LIGHT UNDERWATER FLUID SUCH AS FRESH WATER OR HYDROCARBONS

摘要

The invention relates in particular to a device for undersea collection of a light fluid the device comprising:
a first tank that is provided with a first opening and a second opening;a second tank covering the first opening, surrounding a portion of the first tank, and provided with a third opening putting the second tank, into communication with the medium surrounding the device;connection means connecting together the first and second tanks:a first pipe opening out into the first tank in order to provide density transport of a phase of the fluid to the surface;a structure for guiding and introducing the fluid into the first tank, which structure extends inside the first tank and separates a first portion of the first tank in which the second opening is provided from a second portion of the first tank in which the open end of the first pipe extends; anda structure for collecting the fluid, which structure extends outside the first tank, is secured to the first tank, and surrounds the second opening.

主权项

1. A device (10, 101, 102) for undersea collection of a fluid (200) of density lower than that of sea water, the device being characterized in that it comprises:
a first tank (11) for receiving the fluid, which tank is provided with a first opening (16) and a second opening (233); a second tank (12) covering the first opening (16), surrounding a portion of the first tank, and provided with a third opening (19) putting the second tank into communication with a medium surrounding the device; connection means (58) for connecting together the first and second tanks; a first pipe (21) opening out into the first tank (11) in order to provide density transport (57) of at least a first phase of the fluid to the surface (94); a guiding structure (64, 234) for guiding the fluid and introducing (53) the fluid into the first tank (11), which structure extends inside the first tank (11) and separates a first portion of the first tank in which the second opening (233) is provided from a second portion of the first tank in which the open end (210) of the first pipe (21) extends; and a collecting structure (92, 235) for collecting the fluid, which structure extends outside the first tank (11), is secured to the first tank, and surrounds the second opening (233).
