Coded Vessel
Coded Vessel
(OP)
We have a Stamped Coded vessel on the jobsite which has not been put into service yet. The ladder clips welded to the outer shell were damaged when being off loaded. The clips were cut off and then ground below apparent metal. What should be done in regards to properly repairing these clips?The Contractor says since it is their vessel they can repair as they deem necessary. I know this is wrong and should be left up to Engineering and the AI, but need some codebook guidance here.

using an approved welding procedure and qualified welder and contractor repairing should have a valid R stamp and he should fill out a R-1 form.
if it were me...i would make them butter the shell to the nominal thickness and then MT the area and UT for thickness.
then weld on clips.
A AI's descretion, he can call it a minor repair and not HYDRO the repair and no R stamp is required, but the paper work should be filed, especially if it has a National Board Registration

If this damage occurred during shipment of a completed vessel, this is a contractual matter that can be settled various ways - one of which was weld repair using the NBIC.
