A covering for a rig structure has plural segments separably connected together to form a loop to enclose a portion of a rig structure. Segments can be added or removed to adjust the size of the covering. A lower edge of the covering is connected around a containment basin suspended from the rig structure to contain fluids captured by the covering. An upper edge of the covering is connected to an adjustable frame suspended from the rig structure. The frame can be raised after the covering is attached to it to tauten the covering.
