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.

Are you looking for an RCI or construction management?
Are you intending on re-using any of the material from the existing roof?

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 ?
RE: Need for API650/653 Certified Inspector / Expert
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?
RE: Need for API650/653 Certified Inspector / Expert
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.

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 ?
RE: Need for API650/653 Certified Inspector / Expert
(preferably 25mm plus thickness)should help mimimise any damage(s)to bottom plates and the underneath compacted area.
Hope this should be helpful indeed!
