Abstract: A method for capturing at least a portion of hydrocarbon fluids vented into the surrounding sea from a subsea discharge site comprises (a) mounting a pressure control device to the subsea discharge site. Further, the method comprises (b) flowing the vented hydrocarbon fluids from the subsea discharge site through the pressure control device. Still further, the method comprises (c) positioning a collection system subsea on a lower end of a tubular string. Moreover, the method comprises (d) flowing the vented hydrocarbons fluids from the pressure control device into the collection system and through the tubular siring after (b). The method also comprises (e) minimizing lateral and vertical loads applied to the subsea discharge site by the collection system.

Abstract: A device for capturing hydrocarbons discharged from a subsea flow passage comprises an elongate tubular structure having a central axis, a first end, and a second end opposite the first end. The second end is open and in fluid communication with the first end. The tubular structure includes a rigid stabbing member extending axially from the second end and configured to he inserted into the flow passage. In addition, the device comprises an annular flexible skirt disposed about the stabbing member. The skirt is secured to the stabbing member and extends radially outward from the stabbing member. The skirt is configured to flex from an unflexed position to a flexed position upon insertion of the stabbing member into the flow passage. The skirt is biased to the unflexed position and has an outer diameter in the unflexed position that is greater than the inner diameter of the flow passage.
