Non Destructive Testing (NDT)

A-GlobalEnergy offers various types of NDT services tailored to suit the requirements of your project.

Eddy Current Inspection

Eddy Current Inspection is a form of NDT inspection used to detect surface-exuding defects such as fatigue without having to remove protective coatings by grit blasting or needle gun. Global Energy Group have successfully applied this technique in the offshore industry worldwide over many years.

Ultrasonic Inspection

This effective method produces quick, highly sensitive results and can be used on most materials if sound transmission is good. High frequency sound pulses are emitted from a transducer above a sample of the material. The sound waves propagate through the sample, reflecting at interfaces and these reflected waves are monitored by a detector above the sample. The depth and type of flaws are ascertained using this method. The testing is carried out from one side of the sample only.

Magnetic Particle Inspection (MPI)

MPI is a proven and reliable method of detecting even the smallest surface, or near-surface, flaws in ferrous materials. The MPI inspection equipment establishes the magnetic field pattern of the material and pinpoints indications by identifying any distortion in that field.
Indications cause leakage of magnetic flux in the vicinity of the flaw and the equipment identifies build-ups of very fine iron particles that gather at the location of the leakage, however small it may be.

Dye Penetrant Inspection (DPI)

DPI is a simple method of detecting surfaceextruding flaws such as cracks or porosity. One step up from visual inspection, DPI offers advantages of large area coverage, speed and low cost. Based on the principle that liquid is drawn into a surface-breaking crack by capillary action, dry powder developer is applied to the surface to draw out the liquid that has penetrated the crack and produce a surface indication.

Hardness Testing

Hardness is affected by composition of material and weld metal, metallurgical effects of welding processes, heat treatment and other factors. A vital part of the inspector’s role is fully acquainting themselves with the limiting factors of various types of hardness machines.Our inspectors use three portable hardness meters, all used for highly polished machined surfaces and providing highly accurate hardness readings.

Visual Inspection

Visual inspection, with or without visual aids, is the original and still highly effective method of NDT. Many defects can be detected by careful direct visual inspection. Optical aids used include lowpower magnifiers, microscopes and telescopes. Boroscopes, endoscopes and other fibre-optic devices are used for inspection of areas with restricted access. These devices can be used with television camera systems. High-speed visual inspection may be used for tubular components.

Wall Thickness Testing

We carry out wall thickness and corrosion monitoring on pipework systems , pressure vessels and metallic structures.

Survey & Scanning

A-GlobalEnergy can mobilise a survey team taking detailed dimensional data through laser surveys, hand measurements, then engineer, identify improvements and provide drawings which can be manufactured and installed.

Dimensional Control

Our expertise in Dimensional Control has made it the focal point of our services. Using Leica 1200 series theodolites with point and shoot technology we capture sub-millimetre measurements, providing the highly accurate information our customers need.

Predominantly used for spool replacement and routing of new piping systems, the extremely reliable data provides precise lengths for piping as well as flange deviations and bolt hole rotations.Dimensional control can also provide setting out information, structural grillage positions and ensure correct alignment of new modules and structures. Key benefits of Dimensional Control are:

  • accurate tie point information to guarantee first time fit
  • clash free routing of new piping and structural systems
  • can be carried out whilst the plant is still live
  • prefabrication of replacement parts reducing shutdown times

Laser Scanning 

Laser scanning captures mass data quickly and is primarily used for clash checking where multiple pipe and plant systems are to be routed. Using our state-of-the-art Z+F 5006 HD Scanners, we can survey 50.5 million points, with a range of up to 80m, in less than seven minutes.

The scans can be co-ordinated and stitched together to form one 360° master Point Cloud Database that can be used alongside PDMS to provide comparison between design and as-built. It can also be integrated with AutoCAD to facilitate modelling alongside the scan information

Key benefits of laser scanning are:mass data capture:

  • can be used 24/7 as the laser is unaffected by daylight
  • automatic clash checking between modeled design against Point Cloud Database
