This invention relates to a washing system for washing tanks or the like, preferably ship's tanks (2) having one or more substantially horizontal stringers (2a-2c), the washing system (1) being provided with washing nozzles which while rotating about a substantially vertical axis are at the same time rotatable about substantially horizontal axes. In order that this washing system (1) shall provide effective cleaning of various nooks and recesses in the tank (2), the washing system comprises nozzle holders (9, 24 or 9, 9a, 24) arranged at various elevations, each of said nozzle holders having at least one washing nozzle (11, 25 or 11, 19, 25). An upper nozzle holder (9) at an upper elevation is detachably disposed on a standpipe (3) connected to the tank (2). An extension pipe (21 or 16, 21) is detachably and non-rotatably coupled to the upper nozzle holder (9) via a coupling (17). A lower nozzle holder (24) at a lower elevation is coupled to the extension pipe (16 or 16, 21) via a coupling (23). A rotary and vertically reciprocatory drive member (13) is adapted, on the one hand, to rotate the upper nozzle holder (9) and the extension pipe (21 or 16, 21) non-rotatably mounted on the…
