Abstract
Apparatus (8) includes a seal head (20) having first and second ends and a sidewall having an internal diameter. The first end of the seal head is open to the environment, and the second end is closed to the environment by an end cap. The seal head includes an aperture (20, 24) configured to accommodate a subsea source. A tubular seal head extension (18) is fluidly connected to the seal head end cap. The seal head extension has an external diameter, an external surface, and a length. A movable element (16) having first and second ends and a sidewall structure having an internal diameter sufficiently larger than the external diameter of the extension forms an annulus between the movable element and the extension. The movable element first end opens to the environment, while its second end is closed by an end cap defining an exit fluidly connectable to a subsea collection system.
