Why NDT testing methods matter
Non-destructive testing (NDT) is the backbone of safety and reliability in industries like oil and gas. At Independent Oilfield Inspection Ltd, we understand the critical role these methods play in identifying potential issues without causing damage to our equipment. Since 1993, we’ve been providing high-quality NDT services, ensuring that our operations run smoothly and safely. Whether it’s ultrasonic inspection or magnetic particle testing, our team is equipped to handle it all. With a focus on the North Sea and beyond, we bring decades of expertise to every project. Trust us to deliver results that meet the highest standards of integrity and precision.
How we deliver our services
At Independent Oilfield Inspection Ltd, we follow a meticulous process to ensure the highest quality of service. Our team begins with a thorough assessment of our requirements, followed by the selection of the most appropriate NDT techniques. Using advanced equipment like ultrasonic flaw detectors and magnetic particle inspection tools, we carry out detailed inspections to identify any potential issues. Our commitment to quality and safety is evident in every step we take. Ready to experience the difference? Call us today to learn more about our services and how we can support with our operations.
Magnetic Particle Inspection
This is a non-destructive testing method used for defect detection. MPI is fast and relatively easy to apply, and part surface preparation is not as critical as it is for some other NDT methods. These characteristics make MPI one of the most widely utilised non-destructive testing methods. The MPI technique is very versatile, it can be used in situ for large batch runs to great effect but it is also easily mobilised which allows it to travel onsite for one-off items.
Dye penetrant inspection (DPI)
Also known as liquid penetrant inspection (LPI), this is a widely applied and low-cost inspection method used to locate surface-breaking defects (cracks, and leaks in new products, and fatigue cracks on in-service components) in all non-porous materials (metals, plastics, or ceramics). We mainly use DPI to assess the integrity of non-magnetic equipment. The technique is widely used in the oil and gas industries and performed in accordance with many industry standards.
ACFM inspection
Many structures and plant components require routine inspection to ensure their integrity. Conventional in-service methods such as MPI or DPI require paint and coating removal and rely heavily on operator interpretation. At best these techniques can determine whether a defect exists but are unable to provide information on defect severity. In order to achieve this, the depth of the defect is required. This can then be used, together with Fracture Mechanics methods to determine whether the component is safe for continued operation.
Ultrasonic testing uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection and evaluation, dimensional measurements, material characterisation, and more.
Ultrasonic Inspection
Ultrasonic inspection is a very useful and versatile NDT method. Some of its advantages are:
-
It is sensitive to both surface and subsurface discontinuities
-
The depth of penetration for flaw detection or measurement is superior to other NDT methods
-
It is highly accurate in determining reflector position and estimating size and shape
-
Minimal part preparation is required
It has other uses, such as thickness measurement, in addition to flaw detection.
Magnetic interference inspection (hotspot)
Our hotspot system is designed to detect and evaluate areas of magnetic interference (hotspots) on downhole rotary equipment such as drill collars and MWD tools. Precision in measuring the exact location and direction of the drilling operation is crucial. The instruments determine the drill bit's position relative to the earth’s magnetic and magnetic north.
We use the non-magnetic drill collars in the measurement section of the drill string to avoid any disturbance whilst data is being transmitted. If the instruments which measure the local value of the earth’s magnetic field are exposed to another source of magnetism, such as steel or contaminated non-magnetic alloy, then the data supplied would be unreliable. This examination will identify interfering magnetic fields which will allow the suspect equipment to be removed from service until the problem areas are removed
Thread Inspection
A large part of our business revolves around thread inspection. Thread inspection is carried out to ensure the integrity of the thread form and the sealing surfaces against mechanical damage or corrosion. Dimensional inspection is also carried out to identify areas of wear and deformation. You can be assured that following a thread inspection your equipment has met the standard and can be presented to your representatives for release.
ISO 9001 certified inspection
Our ISO 9001 certification is a testament to our commitment to quality and reliability. It ensures that every inspection we carry out meets the highest industry standards, providing us with peace of mind and confidence in our services.
