Are there any good computer programs for 4 leg sling design ?

[bertyboy]

I am a Structural Engineer, working in the offshore oil and gas industry.
I am looking for a computer program that can design 4 leg slings,
in accordance with the commonly used codes, in this industry.
Can anyone tell me if there is such a computer program ?

Thanks, Bert.

Does it require a computer program? Probably could be done by simple calculation, refer any basic lifting equipment literature + Bridon's blue book.
