A system and method to transfer oil cargo from ruptured tank(s) of a tanker to receiving vessel(s) or receiving tank(s), while maintaining a partial vacuum in the ullage space of the ruptured tank(s). A partial vacuum is created and maintained in the ullage space of tank(s) of a tanker to reduce outflow of liquid such as oil in the event of a ruptured tank. The vacuum is continuously maintained in a precise balance responsive to the forces acting on the contents of the tank, which forces change when the tank is ruptured. According to the preferred embodiment of the invention the liquid cargo in the tank(s) of the ruptured vessel is transferred to tank(s) of receiving vessels or any designated receiving tank(s) while maintaining the partial vacuum in the ullage space of the tanks of the ruptured tanker or vessel. The partial vacuum in the ullage space of the ruptured tank must be maintained while the oil is transferred to tanks of a receiving vessel, otherwise catastrophic oil spillage may occur.
