In-Service Steel Tank Floor Inspections

Looking for Inspection Techniques/Methods for the inspection of Steel Tank Floors without taking the tanks out of service. I am aware of Acoustic Emission, TANKPAC etc... but, are there any new techniques out there? Long Range UT, ACFM?!? Any of these able to do the job?

Re: In-Service Steel Tank Floor Inspections
You really need to look at what you want to achieve.

All of the techniques you mention have some role to play in an on-stream storage tank inspection. They all also have limitations.

If you want in inservice snapshot of the condition of a tank floor in service you are probably limited to Acoustic Emission or an In Service Tank Robot.

Differing methods in terms of data and cost so you need to examine cost benefit analysis.

You could start with an RBI study and then apply in service techniques on high risk.

If annular problems are suspected long range ultrasonics will fill a need.

For more information consider attending Asia Bulk Liquid Storage Tanks & Terminals March 26/27 Singapore check www.ibc-asia com/bulkliquid.htm

es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
