1 FloormapVS2i

2 Computerized Magnetic Flux Leakage Tank Bottom Inspection System

3 The battery powered, motorised scanner is complimented by the powerful, yet easy to use software. FloormapVS2i

4 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

5 A new encoder system has been developed, giving positional accuracy to within 3mm on an 8 metre track length. FloormapVS2i

6 Powerful, easy to use software simplifies data collection, data analysis and reporting. FloormapVS2i

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

8 The FloormapVS2i is the most operator friendly, comprehensive tank floor inspection system available today. FloormapVS2i

9 Magnetic Flux Leakage FloormapVS2i Basic Principles

10 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

11 The FloormapVS2i uses powerful permanent rare earth magnets, which achieve local magnetic saturation of the tank floor plates Permanent Magnets Basic Principles of MFL

12 An array of 36 Hall effect sensors are mounted between the 2 magnet poles Sensor Array Basic Principles of MFL

13 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

14 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

15 Basic Operation – Collecting Data

16 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

17 All operator controls are easily accessible and simple to use. Basic Operation – Collecting Data

18 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

19 All scanning options are shown as graphical images to increase production rates and help minimise operator error. Basic Operation – Collecting Data

20 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

21 The FloormapVS2i Data Acquisition software captures the MFL signals and displays the location and severity of the corrosion on screen. Basic Operation – Collecting Data

22 The software displays a colour coded map of the floor plate. Corrosion severity is represented by differences in colour. Basic Operation – Collecting Data

23 The user can filter the level of corrosion so only relevant defects are displayed on screen. Basic Operation – Collecting Data

24 More specific corrosion information can be seen by holding the cursor over the corrosion. Basic Operation – Collecting Data

25 All data from the current inspection is automatically transferred to a USB memory drive with one button click. Basic Operation – Collecting Data

26 Reporting Software

27 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

28 Once the data is imported, the reporting software automatically positions each plate to produce a plan of the tank floor. Reporting Software

29 Other tank features and notes can be added. Reporting Software

30 Corrosion can be shown as individual coloured pixels. Reporting Software

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

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

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

34 The software features a powerful patch repair design tool. Reporting Software

35 Defects from any other inspections can be added to the tank floor report. Reporting Software

36 Weld inspections can also be added with additional comments. Reporting Software

37 Full defect statistics analysis. Reporting Software

38 Easy to use, powerful, customizable report configuration. Reporting Software

39 Produce a printed copy of the report. Reporting Software

40 Produce a printed copy of the report. Reporting Software

41 Produce a printed copy of the report. Reporting Software

42 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

43 Thickness range: Maximum 12.5mm (automated sizing mode) 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 FloormapVS2i - Specification

44 Floor plate cleaned to bare metal using high pressure washing Floor cleaned to acceptable standard – some thin scale remaining Generally acceptable – some spurious results possible from blisters Floor acceptable – top surface pitting now visible Surface Preparation Requirements Acceptable Floor Conditions

45 Surface Preparation Requirements Product residue and hardened scale present 60mm thick layer of product residueHardened scale and loose corrosion products Thick layer of scale present Not Acceptable Floor Conditions

46 We are convinced that the powerful reporting software coupled with the advanced FloormapVS2i scanner makes this the best tank bottom inspection system on the market today. FloormapVS2i
