Abstract: A method and an apparatus for facilitating purging a vessel (1) by means of an inflatable bladder (3), the bladder (3) being connected to a conduit (53, 55, 57) for communicating a fluid into or out of the bladder (3), wherein the method comprising : - arranging the bladder (3) in a compartment (5) outside the vessel (1), the compartment (5) being provided with a closable sealing means (7) adapted for selectively bringing the compartment (5) in fluid communication with the internal of the vessel (1) via an aperture (9) in a portion of the vessel (1); - bringing at least a portion of the bladder (3) into the vessel (1); - inflating the bladder (3) by means of a fluid provided from a fluid source; - cleaning the vessel (1) by purging a space which is defined by an internal surface of the vessel (1) and an external surface of the inflated bladder (3); - deflating the bladder (3); and - bringing the bladder (3) out of the vessel (1) and into the compartment (5).
