O & K Inspections, here in Louisiana, has a department designated strictly to storage tanks.

As a matter of fact, I am going to be in Angola, Africa in the beginning of March as the 653 for a few tanks for Chevron Texaco in Molongo, Cabinda. We do work for them on a regular basis, travelling there approximately 3-6 times a year. We have a handful of inspectors, including myself, who have passports and up-to-date shots for that region.

There are a bunch of companies which provide these services check ilta.org.

Are you looking for an RCI or construction management?

Are you intending on re-using any of the material from the existing roof?

Do a google search for tank industry consultants. There should be lots of hits as there are several firms that specilize in those services.

Many thanks for your answers.
We are still looking for an audit / detailed inspection.(Bonswa, still expecting an answer from O&KI)
We do not intent to reuse the damaged ERF because too much deformed
Because of operation / schedule constraints, it is envisaged to remove the EFR in sitù by using a track excavator despite I recommended to lift the damaged EFR at + 2 m by jacking and blocking with wooden supports or by loading the tank (water or oil)because of the necessity to investigate the EFR bottom side with all insurers expert to try and understand the causes and in order to avoid any damage to the bottom plate or to campacted backfill underneath (the tank is new)during the removal, and then to demolish carefully
Does some body has a point of view about the most appropriate method ?

Are your support legs damaged beyond the point of using them? I would think the safest way would be to fill it with water up to the point that you can set the legs at the highest level. From there, you can go in and block it as you go. Once blocked, call in your insurance guys and whoever else needs to get a look at the damage.

When you're done with the cause analysis, cut a door sheet, bring in the excavator and cut that thing out. it's easier, safer, and depending on your safety, it may not be considered a confined space anymore. Then, you call in your inspections.

BTW, who did you speak to at O&K?

Was Anti Rotating Device(s) in place and remained OK Or Got damaged as well!

Are there significant evidence(s) to prove/indicate that all the pontoons were intact and roof remained balanced during the episode?

Or the pontoons also got damaged,Filled up with Crude Oil and EFR got tilted or stuck up and the material came on top?

I Hope the replies to above should show way forward to analyze & help resolution.

Thanks for your answers
How to protect efficiently the bottom plate to avoid any bulge and an damage to the backfill underneath?
- Temporary additional plates ?
- Types filled with sand ?
- Other ?

Use Heavy Thickness steel Plates Below the Excavater operation area

(preferably 25mm plus thickness)should help mimimise any damage(s)to bottom plates and the underneath compacted area.
Hope this should be helpful indeed!
