USING MODERN 3D SCANNING TECHNOLOGY MAPPING YOUR SITE FOR ANALYSIS, MODELING AND DOCUMENTATION
TANK ANALYSIS
For bulk storage operators, capturing accurate tank data is an intrinsic part of ensuring efficient day-to-day running of your facility. Whether it’s for production, engineering, maintenance or health & safety, having a complete record that can be easily shared with colleagues across the globe is invaluable.
You will no longer require temporary access platforms to elevate your traditional equipment into position to collect tank surface information, nor will you be limited to a few hundred data points providing minimal information for your reports. 3D laser scanning is cost-effective and very fast, providing many millions of data points for analysis and reporting.
In worst-case scenarios, inaccuracy or absence of data can lead to costly incidents such as a storage tank rupture, with consequential costly repairs, loss of production and negative environmental impact. The storage sector has already benefited from our 3D laser scanning technology, supported by our tank analysis program.
Tank scanning can be completed before influencing factors such as temperature or tank contents affect your results. We produce full tank analysis reports tailored to your requirements.

SCAN DATA EXAMPLE
The image left shows raw scan data of a tank. Our tank analysis reports provide a number of outputs:
Rollout gradient map, radial deflection, shell verticality,
tank settlement, bund volume analysis, tank calibration,
tank floor level analysis
THE BENEFITS
RADIAL
DEFLECTION
By taking radial cuts horizontally through the middle of each tank plate (as many as required) we can observe the radial deflection of a tank compared to a true cylinder (an accurate 3D model of the tank)
ROLL OUT
GRADIENT MAP
An 3D Model serves multiple purposes in the battle to save time and capital. New projects/works must overcome a multitude of design hurdles, including how they will fit/tie into your existing brownfield site. Our maps are able to provide the smallest of details to help you plan.
SHELL
VERTICALITY
By taking a vertical cut at regular intervals (usually every 10m) through the side of the tank around its circumference, we gauge the tank’s vertical integrity.
TANK
SETTLEMENT
Using 3D scan data, we take measurements of the height of the skirt around the whole tank, to check for signs of settlement.
BUND VOLUME
ANALYSIS
For operators using earth bunds for containment, our scan files offer the most accurate method for calculating bund volumes. We can not only assess ground levels, but can interrogate the variances that occur with natural bunds.
TANK
CALIBRATION
Using scan data from either inside or outside the tank, we capture area measurements, every 1mm up the tank, including volumes from tank nozzles, manways etc. Traditional surveying methods using Total Stations would record 160 points, whereas we are able to record over 1 million per second.
TANK FLOOR LEVEL ANALYSIS
Surveying within the tank with 3D laser scanners, we are able to map the whole tank floor to accurately calculate the lowest
point within the tank, allowing a water draw-off line to be added in the optimal place.

Risk & Method Statements
A3D recognise that any form of site work on an operating site must be subject of both RAMS along with planning documents in order to expedite an efficient and safe survey.
3D Laser Scan
Recognised as the referred method for accurately capturing measured site data in using 3D laser scanning instruments. Traditional methods being time consuming and subject to error.
Register Scan Data

FREQUENTLY ASKED QUESTIONS
Do you need access inside the tank?
We don’t need access inside the tank as we can collect the data from scanning outside. If you require a tank floor inspection you will need internal access.
Do you have confined space training?
All of our surveyors are equipped with confined space training.
Can your data help us with floating roof hangers?
By Scanning a tank we can work out the ovality which will then give us an idea on how the floating roof will sit when installed.
Can you determine tank movement between two dates?
By collecting the data using laser scanners surveyed for tank analysis the data can be used to see if there’s movement over a period of time by having it scanned again.
