ABSTRACT:
A marine vessel cleaning assembly (1) comprising cleaning means (5, 6) and displacement means (17a, 17b) supported on a framework (18) for location under the water, the cleaning means comprising a pair of brushes (5, 6) rotatably mounted on a pair of arms (3, 4) which are pivotable about a submerged axis (A—A). In use the brushes are caused to rotate and contact fouling on the hull of the vessel and are pivoted generally upwardly and downwardly of the hull, the vessel being conveyed with respect to the pivotal axis of the arms (3, 4) so that the entire hull of the floating vessel may be cleaned. The inventive cleaning assembly advantageously eliminates the significant financial costs associated with arranging for a marine vessel to remain on hard-standing and also reduces the time required to clean the hull of a marine vessel.
