Lizard^® M8 DIVE System

Subsea DiveScan

LIZARD^® Subsea DiveScan Systems - Easily deployable, ruggedised and remote controlled operation for deep subsea inspection work.

An Industry standard unit, complete portable field proven, self-contained Electromagnetic Crack Detection and Sizing system for structural inspection.

Consisting of:

• PC Interface and Controller (M8-Dive unit)
• Subsea Unit - DDPU (rated to 23bar)
• Digital comms wire link up to 1.2 km with Phantom Power.
• Fully intrinsically isolated low voltage power, for safe operation.
• Inspection Software: LISS.

Lizard^® M8-Dive - provides uncompromising performance in one low cost instrument whether your need is eddy current, Lizard^® AC Field Measurement or advanced Lizard^® Field Gradient Imaging (FGI) inspection.

If your background is in phase plane eddy current inspection work, M8-Dive provides a familiar and easy to understand interface within a Windows™ environment, with context sensitive help files built in. The same tool allows you to move into Lizard^® AC Field Measurement, EMA or FGI modes for more complex inspections at no extra cost. Compliant with EN1711 inspection work.

Crack depth calculations are based upon initial mathematical modelling further enhanced by advanced algorithms. Functionality checks demanded by international standards and quality assurance procedures are stored to provide high reliance on validity of inspection data.

A standard "plug and play" connection via USB or RS232 connects to any laptop or PC running a Windows™ OS.

Smaller, lighter and with more capabilities than any other equipment on the market.

With a Lizard^® Probe the operator has a choice of continuing in phase plane mode (For small / single array sensors) or switching to Lizard^® AC Field Measurement or EMA / FGI operation where our patented planar array probes can be utilised. The software provides geometric and lift-off correction for inspection through varying thickness of coating.

ADVANTAGES / CAPABILITIES Completely field proven EMA Crack Detection and Sizing system in both robotic and diver based structural integrity inspections, an industry standard. Third Party approved. Choices from the patented Lizard® EMA, field gradient and conventional probe suites. Allows surveys from 3 to 200mm widths in a single pass, through up to 8mm of many coatings, surface roughness or fouling with no requirement to clean back to bare metal. Unique system design provides for dual probe subsea operation and inspection of complex structural geometries. Digital high speed communication, data acquisition and storage. Lizard® operational software for complete field proven inspection data acquisition, reporting and archiving. Multi-mode data and analysis and display. Suitable for use with ROV inspection systems.

SIZING MODES

• EMA Crack Detection with LENGTH and DEPTH sizing using the unique electronic ruler and cursor measurements.
• Advanced analysis through Correlation for ease of defect detection.
• Elliptical crack profile fitting etc.
• Geometric and lift-off correction.

MULTI AND ARRAY MODES

• Array Processing.
• AC Field Measurement.
• Multi Dimensional.
• Interface to advanced electronically scanned 3 dimensional defect-imaging systems.
• Phase plane for cross hatch scanning on particular geometries.
