Acoustic Emission technology is an advanced NDT technology with unique advantages:

• In-service evaluation of plant asset integrity
• Non-invasive inspection
• Single instance quick inspection of large surface area
• Detects early onset of growing defects as well as their severity
• Material independent (metals, composites, ceramic, concrete etc.)

Alternating Current Field Measurement (ACFM) is used for detecting and sizing surface-breaking flaws. ACFM is also applied to structures both in and out of the water. (It has the advantage over some other techniques that the structure requires minimal cleaning and that it can be applied over paint and other coatings up to several millimetres in thickness).

Applications

Alternating Current Field Measurement (ACFM) is particularly suited to the detection and sizing of fatigue cracks at the toes of welds, including all butt, fillet, node and nozzle welds. ACFM to inspect fillet welds in Mobile Offshore Drilling Units (MODUs) to detect any possible original fabrication hydrogen cracking present at weld toes.

• Offshore cranes
• Storage tanks floor & roof ‘lap’ joints
• Storage tank annular welds internal & external
• Vessel nozzles

Corrosion and erosion can inflict significant damage upon petrochemical vessels, tanks and pipework. Due to the risks involved, it is important to recognize corrosion damage as early as possible, especially when such knowledge can assist in planning your operational maintenance strategy. With corrosion mapping systems, solutions are available to assist you in developing condition-determined maintenance strategies which can be used in the calculations for the remaining lifetime of a plant. Our strategies can also be used within a structured plant maintenance program and we also offer a visual representation of the results with a comprehensive report of the affected areas helping you to avoid unplanned shutdowns.

Rapid Motion Scanner (RMS)

The RMS is a high-speed, high-accuracy remote access ultrasonic corrosion mapping system designed to evaluate the condition of ferrous structures such as storage tanks, pipelines, pressure vessels and other critical equipment, supporting effective and safe operation. The RMS2 can give 100% coverage in a band up to 1000 mm wide, significantly increasing the Probability of Detection (POD) of corrosion, enabling engineers to determine the optimum repair strategy and improve risk life assessment (RLA) & risk-based inspection (RBI) maintenance programs. The RMS2 is extremely flexible with a range of scanning heads to suit different inspection requirements.

Scorpion 2 Robotic Crawler

Scorpion 2 dry coupled remote-access ultrasonic crawler brings major efficiency and data improvements to tank shell inspections and other structures such as vessels and offshore installations. API 650/653 compliant, this powerful duo is the perfect solution for in-service inspection of your assets.

Scorpion 2 is equipped with the best ultrasonic electronics and software the industry has to offer. With its advanced filtering, the system can inspect materials 4.7 – 100 mm (0.19 – 3.94 in) faster and more accurately than other solutions on the market.

R-Scan

The R-Scan is a manual, dry-coupled B-scan ultrasonic scanner which can be used on a wide variety of components ranging from 50mm diameter pipe up to a flat surface. The R-Scan continuously records ultrasonic thickness measurements as the scanning head is moved over the inspection surface. The recorded UT thickness information is presented as an A-scan trace, a digital thickness measurement and a B-scan thickness profile. Inspection results can be viewed in real-time in the field or recalled for post-inspection analysis at a later date.

R-Scan can be used for inspection of Piping starting from 2” dia., also it can be used as complementary for RMS scanner for testing of inaccessible or limited access areas.

Digital Radiography or DR is an advancement of traditional Radiography. This technique utilizes DDAs (Digital Detector Arrays) instead of Film or CR (Computed Radiography) to create an instant Image. The Radiation reaches the DDA, which has passed through the object, is converted by a Scintillator into visible light and then translated into a digital Image.

The physics (Angles, Penetration, technique etc) remain similar and only mild changes are required to make the transition to DR.

Digital Radiography involves using a source of X-ray or gamma rays. The source sends the rays through the test piece. Following that, a DDA panel (detector) that is sensitive to these rays is placed behind the object. The test piece absorbs part of the radiation and therefore, areas with higher density or thickness absorb more of the rays resulting in an image on the DDA. The detector sends the digital image to a Tablet or PC, and the operator can see the resulting image on the screen immediately.

Digital RT is a good tool for Corrosion monitoring (even through insulated, covered pipelines), for weld inspection such as looking for Cracks, Gas inclusions, Porosity, lack of penetration, etc., and for Wall thinning (profiling).

In Magnetic Flux Leakage (Tank Bottom Inspection) technology, the component required to be tested is magnetized to a saturation level at which the presence of a significant local reduction in material thickness distorts the internal magnetic field, allowing flux lines to break at the area of the discontinuity.

With MFL, sensors are used to give an electrical signal at the leakage site. This signal operates an audible or visual alarm to alert the inspector or stores the event for computer mapping of the area.

The storage of dangerous goods in tanks must be done safely. To reduce the economic as well as the environmental risks to a minimum, a thorough knowledge of the condition of the tank, and in particular, the tank floor is of outstanding importance. To minimise inspection time ARISE Global offers you a quick and reliable inspection, by combining:

Magnetic Flux Leakage (MFL) for tank floor inspection, Hand scan for the inspection of areas with limited access and Ultrasonic Testing (UT) for verification of some areas expected to undergo corrosion. By using those techniques, corrosion can be effectively detected.
