Abstract
For abrasively blast-cleaning the bottom of a ship hull while the ship is supported on blocks on the floor of a drydock, an upwardly facing closed cycle abrasive wheel having a durable but compliant seal projecting forwards around its frontal perimeter, is mounted for transversal movement along the moderately articulatable rails of a mobile carrier. A control panel is provided for effecting traversal, for controlling spraying of abrasive, for controlling X-Y movement of the carrier along the drydock floor, and for extending and retracting rail end support jacks of the carrier frame for locally conforming the vertical positioning of rail ends to the bottom of the ship.
