Eddy Current (ECT)

Eddy Current Testing (ET) is a versatile NDT method that can be used to detect (near) surface defects in conductive materials without removing the coating. An electromagnetic inductor is used to generate a magnetic field. When this field is introduced in the surface of the test piece, it generates so called “eddy currents” in the material. These currents generate their own magnetic field which resists the initial field created by the inductor. When a discontinuity disturbs the eddy currents, this can be registered by measuring the resulting change in impedance of the coil.

Besides detecting defects in the (near) surface, ET inspections can also be applied for material and coating thickness measurements, material identification and heat treatment monitoring.

Long Range Ultrasonic Testing (LRUT)

Long range ultrasonic testing (LRUT), also known as guided wave ultrasonic testing, is a fast and cost-effective method for inspecting long lengths of pipe. Skydew Energy Services limited specializes in using LRUT at oil and gas and other sectors.

Our inspectors are highly experienced in using LRUT and are ASNT/CSWIP Level I or II and qualified; they can provide you with an accurate assessment of the condition of your pipelines.

With LRUT, we can inspect hundreds of metres of pipe from one single location in a day.
The benefits of long range ultrasonic testing includes:

Screening long lengths of pipe at one time
Inspection of 100% of the pipe
Detection of corrosion and erosion under insulation of pipes
Analysis of pipes at difficult-access locations, such as wall penetrations, road crossings and buried sites
Screening of on and offshore pipework, even in tightly packed racks
Riser inspection

Alternating Current Field Measurement (ACFM)

Alternating Current Field Measurement (ACFM) is an electromagnetic technique for the detection and sizing of surface breaking cracks. The main advantage of the technique is that it works through several millimeters of coatings. This means that paint and other protective coatings do not have to be removed and then reapplied.

Magnetic Flux Leakage (MFL)

Magnetic flux leakage (MFL) is commonly used for inspecting tank floors in the petrochemical industry. Corrosion of the tank floor can lead to the loss of product and cause damage to the environment. Therefore, it is vital that tank floor inspections are carried out in order to prevent the occurrence of such problems.
MFL provides a cost-effective and high-speed inspection of tank floors. Our qualified MFL inspectors are backed by years of experience.
