Abstract

On a ship, the longitudinal beams and the framework girders of different decks or of the inside bottom are arranged in identical vertical planes. In at least some of the rectangles defined by the longitudinal beams and the framework girders, there are access openings located vertically above one another. The openings in a vertical group are practically all the same size and aligned with one another vertically. Between corresponding junction points of the longitudinal beams and the framework girders above one another, vertical props running intercostally are located at the corners of each access opening. At least the third and subsequent access openings from the top are closed, preferably in a water-tight manner, by identically-sized removable access covers having at least two pieces each.
