ABSTRACT:
Outflow of oil from a damaged tanker having some tanks dedicated for carriage of oil and others for sea water ballast is minimized by transferring oil out of the upper part of any damaged tank to one or more empty ballast tanks. This is accomplished by installing a passageway in bulkheads common to a cargo tank and a ballast tank which is normally closed by at least a one-shot valve including a blank flange bolted to a section of pipe and a hydraulic hose compressed by the flange which, when pressurized, breaks the bolts to release the flange and open the passageway to allow oil to flow from the damaged cargo tank to a ballast tank.
