shell reparation
(OP)
we have a crude oil storage tank that has a very damaged 1st shell. Pittings are Spread on most of the underside area of the 1st shell plates( about 40 cm from the bottom). the thickness loss is in some places about 66% of the original thickness.
the shell original thikness is 22 mm ( 0.866 in)
the storage tank Diamiter is 60.8 m (200 foot)
what do you think is the best reparation strategy?

RE: shell reparation
- How old is the tank, what type is it and what types of crude was stored ?
- Was there a protective inner coating on the tank and is this repair due to a coating failure ?
- Did the tank corrode at the chine or was the failure through the tank bottom ?
- Do you plan to use protective coatings inside of the repaired tank If so, which type of coating will you use ?
Thank you and best regards ....

MJCronin, the Tank is not very old. It was built in 2002. the crude oil is Sahara Blend with a API gravity of 45°
yes there was a protective inner coating and this repair is due to coating failure.
the hole tank bottom is corroded and we are consedering a seconde bottom option
we are planning to use protective coatings. the bi-component type.
