COMPRESS provides option to design lifting lugs for vertical lift, and also lugs for lifting/turning vessel (including the tailing lug). See the options under the "Attach" menu.
The lifting lugs are attached only to the pressure boundary material (eg: heads, cylinders, cones). Tailing lugs can be attached to support skirts.
COMPRESS does not provide option to attach lifting lugs to structural supports such as skids, etc.
