Device which provides an underwater dry workshop environment for ship propeller inspection and repair

摘要

There is disclosed a means and a method for inspecting and repairing a propeller on a propeller shaft on a ship. The ship is in the water. A truss is positioned on the propeller shaft. A habitat bag is positioned over the upper part of the propeller and is attached to the truss. Then, the truss is inflated with air. An inspector and/or a repair person can enter into the habitat and work in a dry environment while the ship is in the water. There is no need, in many instances, to place the ship in a dry dock.
