ABSTRACT:
The off loading of bulk particulate cargo from self unloading ships creates considerable dust. A self erecting canopy arrangement is described which connects between a ship's boom and a dockside hopper and which can adjust to sudden movement of the boom created by the effect of wind and waves on the ship. The canopy comprises a pliant skirt and resilient, self supporting means such as an inflatable framework for supporting the skirt.
