	MFL Corrosion Mapping Tank Inspection Floor Scanner Developed by Silverwing (UK) Ltd

The FloormapVS2i floor scanner is a MFL system designed to detect and size underfloor corrosion for above ground storage tanks. The FloormapVS2i is latest version of the best selling magnetic flux leakage (MFL) floor scanner and now comes with up-graded magnets to improve defect detectability and sizing on thicker materials, faster data capture with a custom designed micro controller and all new software. The VS2i contains significant improvements in terms of defect positioning, electronic data processing and software manipulation.

Key Features

Automatic CAD Drawing

Patch Plate Design Feature

Ruggedised Touch Screen Computer

Real Time Data Acquisition and Analysis

Hard Copy and Electronic Report Function

Combined Defect Profiling and Amplitude Analysis

Add Data from Visual, UT, Vac Box and MPI Inspection

A new High Specification encoder system has been developed which is electronically calibrated to each individual scanner eliminating errors caused by component tolerances. The new encoder now gives accuracy to within 3 mm on an 8 metre track length and providing it is calibrated on an annual basis will not be effected by normal wear and tear.

The ruggedised on-board computer uses touch screen technology for ease of use within the hostile storage tank environment. The custom designed data acquisition software not only captures all the MFL signals but analyses and displays the location and severity of the corrosion in real time.

The off – line reporting software automatically produces a CAD drawing of the tank floor with the defects being positioned to within 30mm accuracy. All captured data, over 20% loss of the nominal plate thickness, is re-analysed to identify the defect profile and separate the corrosion into 1 of 3 classes. Different sizing algorithms are applied to each class of corrosion ensuring enhanced defect sizing even on badly corroded floors where small diameter deep pits may otherwise have been undersized.

Additional data from visual, ultrasonic, vacuum box and magnetic particle inspection can be added to the report generating a full fingerprint of the tank floor including the annular plates.

Please Note: in order for you to run the Demo software you will need to download Microsoft DirectX 9, .NET Framework Version 2 and .NET Version 3.5, andunless you have them pre-installed. These are approx 100mb in total.


Tank View	Plate View	Linked Photo	Statistics	Patch Plate Design Tool
Overall view of the tank floor showing areas of corrosion.	View individual plates in more detail including exact position and percentage loss of corroded areas	Digital photos can be attached to specific areas of the tank floor.	Show number of discontinuities in bands of 10%. View statistics for the entire tank or individual plates.	Easy to use patch plate design tool. The software produces a material list and details the total amount of material required to make repairs.

An innovative feature of the software allows subsequent inspection data to be overlaid and corrosion growth identified.

These features coupled together with a patch plate design function and full statistics package give the tankage engineer a powerful, cost effective tool with which to carry out trending and asset life projections
