Manway tailing lug

Manway tailing lug

Manway tailing lug

(OP)
I have been working on a project that requires me to demolish a vessel.  The original tailing lug is buried in fireproofing, so we're no really sure where it is (and we don't want to spend the time and money tearing out the fireproofong to find it).

I want to use a bottom manway as a tailing lug by welding a lug to it.  I have looked at Moss 3rd Ed, Procedure 7-7 but haven't found it very useful for this situation.

Does anybody have experience with this ?  COMPRESS doesn't address it.  A spreadsheet would be great.

Thanks for any help.

RE: Manway tailing lug

How do you intend to remove the anchor bolt nuts without removal of the fireproofing?

If the original tailing lug is missing or damaged, you could prepare a tailing beam to bolt up to the anchor bolt holes. I presume that since you need a tailing device that this is a large enough vessel so that it would have plenty of anchor bolt holes to work with. Raise the vessel a foot or so and slide the beam under it, bolt it up, and continue.

On the other hand, using the manway is not a bad idea. The Moss procedure provides decent guidance on the lug itself, but you'll need to check the nozzle and shell as well. Shear and bending for the nozzle neck, local loads per WRC-107 or FEA or other for the shell connection.
