ABSTRACT:
A method of automatic underwater painting over metal surfaces of ships and offshore constructions is disclosed, which broadly comprises the steps of freely running a painting machine along the metal surface, sealably attaching the machine onto the metal surface of a location as desired and thereby forming a painting chamber over the metal surface for painting, transferring the water within the painting chamber to a ballast tank of the machine, and while paint jetting nozzles of the machine being reciprocated within the painting chamber, jetting a paint to effect an even painting over a wide area of the metal surface. The painting machine, which is also disclosed, includes an improved maneuvering mechanism, improved buoyancy adjusting mechanism, improved waterproof electromagnet, nozzle driving mechanism and paint circulation system.
