Apparatus and method for containing and recovering undersea oil or gas well leakage by reason of the leaked fluid being lighter than sea water may include a canopy, or a series of interconnected canopies, which, when placed over a leak site, allow leaked fluid to be captured and displace sea water with the canopy or series of canopies having an arrangement, such as one or more conduits, for flow of leaked fluid upward from a respective canopy to the surface. With a system with multiple canopies in a series with exit arrangements for leaked fluid from a lower canopy to a next upper canopy, the series can readily extend from the surface to a great depth and allow transfer of volumes of the leaked fluid that are not limited by the capacity of canopies or conduits at deep locations.
