An apparatus for localized cleaning of a surface, particularly a subsea surface such as a hull of a ship, riser, pipeline or the steel jacket of a platform comprises a body 4, at least one jet or nozzle 16 mounted on the body 4 for directing a high pressure stream of fluid at the surface and a securing device such as a plurality of magnets 18 is mounted on the body 4 for attaching the body 4 to the surface. The apparatus further comprises a base member (9, fig 2) extendable from and retractable within the body 4 and means for moving the base (9, fig 2) with respect to the body 4 from a first position in which the body 4 is in contact with the surface to a second position in which the body 4 is spaced from the surface such that the position of the body 4 can be finely adjusted relative to the surface before the securing device 18 is engaged with the surface to firmly hold the body 4 on the surface. The arrangement allows for fine positioning and soft landing of the apparatus. |
