Abstract: This publication relates to method and a system for emptying a liquid containing cargo tank, comprising a closable volume (1 ) arranged below and in liquid communication with a cargo tank (22) through closable opening, where undrained cargo upon completed emptying process from the cargo tank (22) will flow into the closable room (1 ); supplying pressurized gas through a gas supply line (3) to the closable volume (1 ); emptying cargo from the closable volume (1 ) through an outlet line (4); while sealing the opening by moving a sealing body(2) into sealing contact with the opening, the motion of the sealing body (2) being provided by the pressurized gas supplied through the supply line (3). The pressurized gas is prevented from being supplied to the closable volume (1 ) until a sealing contact between the sealing body and the opening is provided, whereupon liquid in the closable volume (1 ) is forced out of the closable volume (1 ) by the pressurized gas. The sealing effect is achieved by means of an actuator is in the form of a piston (13) and a cylinder (34), and that the cylinder (34) is provided with an closable orifice (5) in fluid communication with the closable volume (1 ), and being configured to remain closed until the piston has brought the sealing body (2) in sealing contact with the opening.
