- Laser scanning offers many advantages over traditional storage tank surveys
COMPLETE DATA CAPTURE: The laser scanner collects thousands of survey points on every surface. We also capture the storage tank surroundings allowing us to look at bund capacity and carry out spill analysis. We can survey inside and outside of storage tanks, as well as above ground and buried tanks.
RAPID: Laser scanning captures millions of points in a matter of minutes.
ACCURATE: The tank floor and tank shell can be accurately modelled to within +/-2mm . ‘Deadwood’ assets can also be modelled. Critical features such as the strike point/plate and roof mounted gauge points, valves and sensors can be accurately derived from the scan data.
Our bespoke software, developed specifically for creating tank volume tables, facilitates the creation highly accurate strapping tables. For high value products, it pays to have accurate volumes.
Hi if possible could could I show this video in a presentation I'm doing in Orlando?
yeah, me too.... I have always been curious to what my city may be up too....
Nice job...The one thing I would do differently is the verticality check. Simply fitting a cylinder to the whole dataset and measuring the difference at the origin bottom v top is not an accurate representation of how off vertical it is as it naturally best fits the cylinder to all the data in between the top and bottom. It would be more accurate to fit 2 separate cylinders using a thing slice of data at the top and bottom and compare these values in X & Y......
+christopher byrne Thanks, I agree with your comment regarding the verticality, which we actually measure in two distinct ways. One is by fitting the cylinder - think of it as an 'overall measure' and one by creating many horizontal sections/slices. Some of the extra analysis is missing or simplified for an easy to understand video.
Thanks for this video,
I need to know does this laser scanner work for the tank calibration ?
Do you calibrate tanks?
Great solution. How did you make the surface unroll? Thanks.
+Gregor Novaković Thanks, we developed our own in-house software to do this. Here's a link to the math: www.mathopenref.com/cylinderarea.html

Thank you very much.
Hello James, where can I get more information about laser tank scanning services? I am looking for a solution to scan underground storage tanks. Thanks & appreciate your reply.
Hi Vikram, I work for a company called Merrett Survey Limited, we work all over the world laser scanning storage tanks. Please visit our website at www.merrettsurvey.com for more information. Alternatively, contact me directly via email: james.rye@merrettsurvey.com

Dear James,
Many thanks for the info. Appreciate it!
Regards,
Vik
how much the equipment price
It depends on what scanner you use to measure the tanks. The video is quite a few years old now and the Leica C10 has been replaced with a Leica P40. Other scanners are available and prices vary from £30,000 to £100,000+ for high accuracy laser scanners.
