摘要

An adjustable height platform (10) is suspended on cables (13) from the vessel roof (6) and comprises at least two parallel and spaced apart beams (11) which are arranged side by side and have a compartmentalised cross- section. The height of each beam can be altered individually. The beams are suspended from the cables and connected via at least one truss (12) extending at right angles to the beams and resting on top of them. The top sides of the beams are flat so that they form a floor (18) on which one can walk and work on safely. The trusses can also be walked and worked on safely and have an overlength which enables them to move the beams in the height and sideways direction.
