The battery powered, motorised scanner

is complimented

by the powerful,

yet easy to use

software.

FloormapVS2i

The ruggedized on-board computer has a vibration resistant hard drive and a resistive touch screen for ease of use within the hostile storage tank environment.

FloormapVS2i

A new encoder system has been developed, giving positional accuracy to within 3mm on an 8 metre track length.

FloormapVS2i

Powerful, easy to use software simplifies data collection, data analysis and reporting.

FloormapVS2i

Photographs and results from other inspections can easily be added to the FloormapVS2i report to show total tank floor condition.

FloormapVS2i

The FloormapVS2i

is the most operator friendly,

comprehensive tank floor inspection system available today.

Basic Principles

The following slides demonstrate the basic

principles of MFL for the detection of corrosion on

tank bottoms as used on the FloormapVS2i …..

Basic Principles of MFL

The FloormapVS2i uses powerful permanent rare earth magnets,

which achieve local magnetic saturation

of the tank floor plates

Permanent Magnets

Basic Principles of MFL

An array of 36 Hall effect sensors

are mounted between the

2 magnet poles

Sensor Array

Basic Principles of MFL

Basic Principles of MFL

The powerful magnet induces a uniform magnetic field close to saturation in the plate

When corrosion is encountered the magnetic field is forced outside the plate

The magnetic leakage field is detected by the hall-effect sensors and converted to an electrical signal

All MFL signals are filtered, amplified and combined with positional information from the optical encoder before being stored on the on-board computer.

Basic Principles of MFL

Basic Operation – Collecting Data

• The FloormapVS2i must be calibrated on a MFL reference plate before being used for an inspection.• The calibration procedure has been simplified to

minimise operator error

Basic Operation – Collecting Data

• All operator controls are easily accessible and simple to use.

Basic Operation – Collecting Data

All FloormapVS2i Data Acquisition software controls are oversized.

The touch screen can be used even if the operator is wearing gloves.

Basic Operation – Collecting Data

• All scanning options are shown as graphical images to increase production rates and help minimise operator error.

Basic Operation – Collecting Data

• Each plate is scanned in a pre-set pattern until the entire plate has been covered.• The width of each scan is 250mm• Maximum single scan length of 15M• Speed of 0.45M per second

Basic Operation – Collecting Data

The FloormapVS2i Data Acquisition software captures the MFL signals and displays the location and severity of the

corrosion on screen.

Basic Operation – Collecting Data

The software displays a colour coded map of the floor plate. Corrosion severity is represented by differences in colour.

Basic Operation – Collecting Data

• The user can filter the level of corrosion so only relevant defects are displayed on screen.

Basic Operation – Collecting Data

• More specific corrosion information can be seen by holding the cursor over the corrosion.

Basic Operation – Collecting Data

• All data from the current inspection is automatically transferred to a USB memory drive with one button click.

Reporting Software

Reporting Software

• Once the inspection is complete, the Floormap data is imported into the offline reporting software.

• There are 2 versions of the reporting software:• FULL version - designed for use by the Floormap

operator provides complete control to all data manipulation and evaluation tools.

• Read Only version - designed to be issued to end clients locks the inspection data, while providing full access to all of the useful evaluation tools, data comparison tools and patch plate

design tools.

Reporting Software

Once the data is imported, the reporting software automatically positions each plate

to produce a plan of the tank floor.

Reporting Software

Other tank features and notes can be added.

Reporting Software

Corrosion can be shown as individual coloured pixels.

Reporting Software

Or each track can be coloured to show the maximum defect found per track.

Reporting Software

The exact position and percentage loss of individual defects can be displayed by placing the cursor over the defect.

Reporting Software

Digital images can be linked to specific areas of the plate.

Reporting Software

The software features a powerful patch repair design tool.

Reporting Software

Defects from any other inspectionscan be added to the tank floor report.

Reporting Software

Weld inspections can also be added with additional comments.

Reporting Software

Full defect statistics analysis.

Issue an electronic report

An electronic copy of the report can be issued to the customer along with the

read-only version of the reporting software.

The read only reporting software locks the data to prevent accidental editing, but

still allows the user to access the powerful reporting tools.

Reporting Software

Maximum 20mm (detection mode only)

• Max sensitivity: 20% under floor corrosion

• Maximum coating thickness:6mm

• Scan width: 250mm

• Maximum single scan length:15 metres

• Speed: 0.5m/ sec

• Power requirements: 12v battery operation - Supplied with 3 batteries and 2 chargers to allow continuous working
