Abstract
A liquid spill device arrangement is disclosed for liquid transfer in a closed system from a terminal or other sender facility to a vessel, such as a tanker vessel, and vapor/gas transfer from the vessel to the sender facility. A single spill device is used to serve multiple tanks of a tanker vessel.
Claims9
A liquid spill device arrangement for use in a closed liquid transfer system from a sender facility to a receiver vessel comprising
- a receiver vessel having multiple tanks for containment of liquid with a common boundary between said tanks, said receiving vessel for receiving liquid from the sender facility and for transfer of gas/vapor from the receiver vessel to the sender facility,
- a pressure relief means for venting gas/vapor at a selected relief pressure from the receiver vessel to atmosphere,
- said tanks having an opening therein near their tops in proximity to said common boundary,
- a closed trunk connecting said tanks through said opening and allowing liquid to flow from one tank to another,
- a liquid spill device mounted to said trunk in communication with said tanks, said spill device for opening at a pressure allowing overfill liquid to flow from containment in said tanks to prevent exceeding their structural design pressure,
- said liquid spill device opening at a pressure equal to or greater than said selected gas/vapor relief pressure of the receiver vessel.
