Abstract

An object of the invention is to provide a remotely-operable vehicle (ROV) which is capable of crawling along and adhering to the structure to be inspected and cleaned, both into and through the splash zone up to at least sea state 5, i.e. that state of the open sea corresponding to at least a wind of force 5 on the Beaufort scale. In accordance with the invention, the ROV has a frame (5, 30) adapted to be held fast during motion in relation to said surface by the alternate energization and de-energization of a plurality of electro-magnets (14, 15 - 38, 40), said electro-magnets being arranged such that at least one electro-magnet is movable in relation to at least one other electro-magnet in order to progress said frame in relation to said ferrous contact surface. The plurality of electro-magnets comprises in one embodiment, a series of electro-magnets (15) fixedly mounted on the periphery of the frame (5) and a cluster of electro-magnets (14) central of the frame and movable relative thereto. In another embodiment there are two transversely spaced slidable electro-magnets (38) and one fixed electro-magnet (40) arranged in triangular formation. Actuators (42) can slidably move one or both magnets (38) towards or away from the fixed magnet (40).
