USING MODERN 3D SCANNING TECHNOLOGY MAPPING YOUR SITE FOR ANALYSIS, MODELING AND DOCUMENTATION
In just four years, Advanced 3D Laser Solutions has quickly established itself with a strong client base in the UK and Europe. After Establishing a strong client base in the UK, the team set its sights on Europe, particularly in the Netherlands, as its offered new opportunities to expand the company’s offering.
For bulk storage operators capturing accurate tank data is an integral part of ensuring efficient day to day running of your facility. Be it for production, engineering, maintenance or health & safety, having a level of recorded information that can be shared readily with your colleagues across the globe can be invaluable.
No longer will you require temporary access platforms to elevate your traditional equipment into position in order to collect information about the tank surface. No longer are you limited to a few hundred data points offering limited information for your reports. 3D Laser scanning is cost effective and in a short period, provides many millions of data points for your 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 repairs, loss in production and negative environmental impact. The Storage sector is already benefiting hugely from use of our 3D Laser scanning technology, backed ably by our tank analysis program.
Tank scanning can be completed before influencing factors including temperature or tank contents can affect your results. Our tank analysis reports are both versatile and informative and can include, but not limited to the following outputs:-
“80M DIAMETER TANK RECORDED FROM A SINGLE
DAYS SCANNING AT AN ACCURACY OF +/-1MM ”
Scan data EXAMPLE
This is the raw scan data of a tank. A tank analysis can provide a number of outputs :
ROLLOUT GRADIENT MAP, RADIAL DEFLECTION, SHELL VERTICALITY,
TANK SETTLEMENT, BUND VOLUME ANALYSIS, TANK CALIBRATION,
TANK FLOOR LEVEL ANALYSIS
Taking radial cuts horizontally through the middle of each tank plate (or more if required) we can take a look at the radial deflection of a tank compared to a true cylinder (an accurate
3D model of the tank)
A 3D Model serves multiple purposes in the battle of saving time and capital for everyday procedures and for future projects. New project work always has a multitude of design hurdles, including how it will fit and tie into your existing brownfield site, the relationship between new plants with your existing, remembering to take into account even the smallest of these hurdles.
Taking a cut through the side of the tank, vertically, at regular intervals usually every 10M around the circumference of the tank we are able to gauge the tank vertical integrity.
Looking at the skirt of the tank we take measurements, using the 3d scan data, of its height around the whole tank. Giving us an idea of its height in relationship to the rest of the tank.
With those operators still using earth bunds
for containment, our scan files now offer
the most accurate approach for calculating
bund volumes. We can not only assess
ground levels, but can interrogate the
variances that occur with natural bunds.
With scan data from either inside or outside
the tank we are to take area measurements,
every 1mm up the tank, taking volumes
from tank nozzles, manways. Bearing in
mind traditional methods, which would use
total stations to record 160points we are
able to record over a million per second.
TANK FLOOR LEVEL
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
of line to be added at the optimal place.

AlS will complete pre-planning in order to determine the most efficient and therefore, cost effective solution.
RISK & METHOD STATEMENTS
ALS 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
Once ALS has been out on site with the 3D Laser Scanners we then process the scan using faro scene software.
AUTO PIPEWORK RECOGNITION
ALS uses pipework recognition software to pick out the pipework from the point cloud data this save valuable time modelling.
STEEL WORK EXTRAPOLATION
ALS can provide steel work models this can aid clients in the situation where they need feed a new line through the site. ALS offer clash detection services.
ADD PIPING COMPONENTS
Auto Cad Plant 3D has a catalogue of spec driven components which replicate onsite assets which can be given individual numbers which correspond with asset management systems.
ADD LINE NUMBERS
ALS uses the clients specific nomenclature which allows us to produce 2D deliverables such as orthos and isos which tie into existing management systems.

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.
ALS are proud to have established point cloud technologies, now recognised as the preferred method for accurately capturing measured site data in using 3D laser scanning instruments. Traditional methods being time consuming and subject to error
The vast engineering experience from over 30 years working within process industries has resulted in ALS now leading in the production of ‘brown field’ technical process models. ALS recognised the importance of our skilled 3D laser surveyors site familiarity.
The ALS Tank analysis reports deliver critical information with a level of detail not previously achieved using traditional methods. since we are using advanced 3d laser scanners with out need for temporary access platforms, thus technology is a market leading competitively priced alternative..
