Lifting and Rigging Analysis
What use is a highly engineered piece of pressure equipment if you can’t safely get it off the rail car and stand it up? COMPRESS and INSPECT include an integrated solution to this complex task. When performing lifting and rigging analysis COMPRESS and INSPECT:
Use an accurate weight
Find the correct center of gravity
Apply the actual pressure vessel cross sectional properties
Benefits of our lifting and rigging analysis include:
Rigging analysis is considered in the vessel design
The governing lift angle for vertical vessels is automatically determined
Lift lugs are designed to be strong enough to avoid tearing or bending
Tailing lug designs consider skirt struts to prevent lift damage to vertical vessel support skirts
More About Rigging
The Codeware rigging analysis can be used with or without the lift lug option. It provides bending moment, shear stress and bending stress diagrams as well as tabulated values at main vessel locations. Variations in local sectional properties along the length of the vessel are considered.
When activated with lift lugs, the lift points are taken as the lift lug locations by default. This can be overridden to provide a quick indication of the effects of relocating lift points (design optimization).
More About Lift Lugs
COMPRESS and INSPECT include a lift lug design option. Plate, ear, trunnion and tail type lift lugs are included. This feature calculates the stresses within the lug as well as the local stresses of the vessel at the lug attachment location. For vertical vessels which undergo a rotational lift from horizontal (shipping) to vertical (in-service), the lift lug is checked for all lift angles (0° – 90°). The governing lift angle condition is automatically found and reported.
Lifting and rigging analysis is just one of the many features enjoyed by users of our suite of software products. To find out more email firstname.lastname@example.org or call us at (941) 927-2670 and set up a software demonstration today.
