Document Type and Number:
WIPO Patent Application WO/2012/004601
Kind Code:
A4
Abstract:
A device for collection of oil and gas from an underwater source comprising a balloon- like structure (1) defined by an envelope having an opening (18), which, in operation, is on the underside of the balloon- like structure, which balloon- like structure includes: a vent (23) adapted to vent gas in the envelope, and control means (2) for controlling the oil upper level having a closure valve (3) adapted to control flow of gas in the envelope through the vent, the valve being closable by a valve closure member operable by a float (8) adapted to float on the oil to determine the minimum volume of gas in the envelope, wherein, in use, the balloon- like structure is adapted to be placed over the source to collect oil and gasses from said underwater source. The balloon- like structure further includes buoyancy means (10, 12, 14, 16, 17) adapted to control the buoyancy of the structure to enable ascent to the surface of the water in a controlled manner. The envelope may be formed of a flexible material to enable it to be collapsed or folded for storage and/or transportation.
