A system for recovering petroleum products such as oil from a sunken oil transportation vessel. The system includes first and second flexible conduits communicating with the oil-containing compartments. The conduits are released upon the vessel becoming submerged. The free ends of the conduits are connected respectively to a pump for pumping sea water into the compartment to displace the oil. The second conduit is connected to a recovery container on the surface. The displaced oil is forced through the second conduit to the recovery container. The recovery container is, in the preferred embodiment, provided on a fleet or network of recovery vessels which then transport the recovered oil to port for off-loading. In the preferred embodiment, the flexible conduits are associated with a float which releases or carries the conduits to the surface so that underwater recovery operations are minimized.
A method for recovering oil from an oil transport vessel having at least one oil-containing compartment submerged below the water level comprising:
The method of 1 further including providing venting means in said at least one oil compartment and causing said venting means to close when water is forced into said at least one oil compartment.
