3d scanning & surveying using laser

3D SCANNING & SURVEYING USING LASER

Laser scanning using LIDAR (Light Detection and Ranging), is a new inspection technology that provide faster, safer and better coverage of any structure. The 3D laser scanner is used to capture millions of individual points on buildings, storage tank’s shell, bottom and roof and the data can be used for fitness-for-service assessments (FFS).

API 653 standards require measured data on the verticality of tank shells, the roundness of tank shells, flatness of the tank bottom and any subsidence.

Laser scanning also captures information on appurtenances such as nozzles, access points, stairs and ladders as well as nearby structures and terrain. Built-in cameras capture digital images that provide additional documentation of tank conditions.

Software is used to take data from an inspection and automatically merge multiple point clouds into a single cohesive dataset. With the software enabling basic clean-up and organization, and the resulting point cloud provides a comprehensive and precise picture of the inspection, enables users to create high-density 3D digital representations of storage tanks, analyse the data following API 653 Standard guidelines and automatically detect out-of-tolerance areas.

APPLICATIONS

1. Storage Tank measurement and calibration 2. Storage tank settlement and deformation survey and

Fitness for service assessments (FFS)

3. Construction structures, buildings, jetty, oil rig platforms, FPSO’s and ship platforms.

ALTERNATING CURRENT FIELD MEASUREMENT (ACFM)

Alternating current field measurement (ACFM®) is an electromagnetic inspection technique that introduces an alternating current into the surface of a component to detect surface-breaking cracks. Its versatility eliminates the need for pre-cleaning prior to inspection on rough or corroded surfaces, or through protective coatings and test indications can be sized to show depth and length of indications. The test can be performed at elevated temperatures as high as 450° C (900° F). ACFM was developed to reliably detect and size in-service defects with a low number of false calls. It was designed to work on rough or corroded surfaces, or through protective coatings. ACFM is extensively used for offshore platform applications on piping and structural supports, in addition to process piping in oil and gas facilities.

APPLICATIONS

• Predictive Maintenance and Condition Monitoring • Piping and Pressure Vessel Insulation issues • locate hot spots and anomalies such as voids and

inclusions • heating, ventilation and air conditioning (HVAC)

equipment’s • Energy audits

DRONES INSPECTION

Unmanned Aerial Vehicles (UAV), or Drones are simply any aircraft that does not have a human pilot.

UAV are primarily used for visual inspection to keep your workforce out of harm’s way while performing flawless inspections using cutting edge drone data capture capabilities. High resolution (HD) cameras with the option of thermography(IR) images, allow them to get a close up, accurate view of a structure, even from a great distance. GPS enabled image stabilization,

They can be used to inspect nearly any structure, both indoors and outdoors, but they are most useful in the inspection of structures that are difficult to reach by traditional means. Data visualization is taken to the next level of 2D data measurements such as measuring length and dimensions of the inspected items.

Compared to traditional inspection, the use of UAV is cheaper, faster, and safer, without requiring shutdown, the construction of scaffolding, or sending inspectors into dangerous situations.

UAS have a range of uses in variety of fields including recreational, commercial, or military purposes.

APPLICATIONS

• Tall structures, such as flare stacks, cooling towers, elevated pipe trays, chimney and smoke stack.

• Storage tanks, Aerial survey. • Confined spaces in which space is limited for traditional

inspections. • Structures that are over water such as bridges, jetty or

the undersides of oil rig platforms, FPSO’s and ship platforms.


EDDY CURRENT SURFACE ARRAY INSPECTION ( ECA )

ECA probes are designed to be flexible and is capable of finding flaws with better detection capabilities techniques. With ECA larger area can be scanned at one time while maintaining a high resolution and wider coverage. The method is less operator dependent with easier data analysis because of simpler scan patterns and C-scan imaging and permanent data recording of inspection data.

Furthermore, materials and welds can be using ECA without removing paint or protective non-conductive coatings (up to 3mm lift-off), unlike more conventional techniques. Complex shapes can be inspected using this method because the probes can be customized to the profile of the part being inspected. ECA can effectively replace the need to MPI and PT on most conditions. APPLICATIONS

• Butt and fillet welds crack detection

• Parent material • Ferrous and Non-Ferrous

materials (use of different probes)

• Flexible probes for various geometric shapes and applications.


LONG RANGE ULTRASONIC TESTING ( LRUT )

Long Range Ultrasonic Testing (LRUT) or Guided Wave Ultrasonic(GWUT) is useful for examining a long length of pipe quickly and from a single location. This technique does not require contact with the pipe except for where the transducer ring is fitted. LRUT is an effective technique for inspecting pipes in difficult to reach locations, such as those in high locations, behind walls, or under insulation. In most cases however, this method is best used as a screening tool part of a larger inspection program. LRUT reduces the removal of insulation and the whole pipe wall is tested, achieving a 100% examination (including areas such as at clamps, and sleeved or buried pipes). LRUT is capable of inspecting pipe sizes up to 78” and increased temperature capability of 240°C.

APPLICATIONS

• Predictive Maintenance and Condition Monitoring • Long lengths of pipes • Corrosion under Insulation Splash zone inspection • Un-piggable pipelines • Jetty pipe work • Buried pipelines & Road crossings




Pu

PULSED EDDY CURRENT (PEC)

PEC can be applied to in-service assets, and can detect damages through thick insulation such as aluminium, stainless steel and galvanized steel weather jackets. It is an effective tool for corrosion-under-insulation (CUI) and flow-accelerated corrosion (FAC) assessments. PEC can be done without need for contact with the surface of the material. Because of this, it can be useful in situations where an object’s surface is rough or inaccessible. This method also doesn’t require surface preparation or removing any insulation. It can be a quick and cost-effective solution for corrosion detection. APPLICATIONS

• Corrosion under Insulation(CUI) • Insulated pipes and vessels • Corrosion under fire proofing • Underwater and splash zone structure inspection • Storage tanks, marine vessels

INFARED ( IR ) THERMOGRAPHY

IR thermography is used to measure temperature variances of a component as heat flows through, from, or to that component. Images of the detected temperature distribution are called thermograms, is used to confirm machinery is running normally and to detect abnormal heat patterns within a machine, indicating inefficiency and defects and they make it possible to see heat-producing objects invisible to the naked eye.

The primary goal of infrared thermography IR thermography is utilized in many industries and applications. In the oil and gas and chemical processing industries, for example, thermography can be used to detect piping insulation issues, fluid levels, or identify trouble spots where rotating equipment is experiencing too much friction. Furthermore, IR testing is commonly used to locate hot spots and anomalies such as voids and inclusions. The benefits of IR testing include extended equipment life, decreased unscheduled shutdowns, reduced risk of equipment failure, and increased performance.

• Predictive Maintenance and Condition Monitoring • Piping and Pressure Vessel Insulation issues • locate hot spots and anomalies such as voids and

inclusions • heating, ventilation and air conditioning (HVAC)

equipment’s • Energy audits
