Traditional Nondestructive Testing

At SUBSEA NDT & Engineering, we offer a comprehensive range of traditional Non-Destructive Testing (NDT) services to ensure the highest levels of asset integrity, safety, and reliability for our clients. Our skilled technicians are certified experts in key NDT methods, including Liquid Dye Penetrant Testing (LPT) for surface flaw detection, Magnetic Particle Testing (MPT) for identifying discontinuities in ferromagnetic materials, Ultrasonic Testing (UT) for precise thickness measurement, corrosion mapping, and weld inspection, and Visual Testing (VT) for fundamental, hands-on assessment of visible defects and structural conditions. Each service is tailored to provide accurate, actionable insights, allowing us to support critical industries with timely, effective inspection solutions.

Liquid Dye Penetrant Testing

Liquid Dye Penetrant Testing (PT) is an essential Non-Destructive Testing (NDT) method used to detect surface flaws on non-porous materials, such as cracks, pores, or seams. By applying a liquid penetrant to the surface and allowing it to seep into surface-breaking defects, our SUBSEA NDT & Engineering technicians can reveal even the smallest discontinuities once a developer is applied.

This method is highly effective for inspecting metals, ceramics, and plastics, especially for components under stress or in high-visibility applications. Our experienced team ensures accurate, reliable results that help clients maintain asset integrity and safety.

Ultrasonic Thickness Testing (UT)

Ultrasonic Testing (UT) is a versatile and precise NDT method that enables thickness measurements, corrosion mapping, and shear wave weld inspection. Using high-frequency sound waves, our SUBSEA NDT & Engineering technicians accurately gauge material thickness, identify areas of corrosion, and detect flaws within welds.

In thickness measurement, UT is invaluable for assessing wall loss due to corrosion, while corrosion mapping provides a detailed view of material degradation over time. On the other hand, shear wave inspection is highly effective for detecting weld defects. Our certified technicians deliver detailed, actionable insights that support asset longevity and compliance.

Visual Testing (VT)

Visual Testing (VT) is the most fundamental yet crucial NDT method for inspecting components for visible signs of wear, damage, and alignment issues. Our proficient SUBSEA NDT & Engineering technicians use direct visual inspection and remote tools such as borescopes to examine hard-to-reach areas.

VT is invaluable in early detection, helping clients identify potential issues before they escalate, and is commonly used across various sectors, from offshore platforms to onshore refineries. Our team’s keen eye and attention to detail ensure a thorough and reliable assessment, reinforcing the integrity of each asset.

Magnetic Particle Testing (MT)

Magnetic Particle Testing (MT) is a powerful technique for detecting surface and slightly subsurface discontinuities in ferromagnetic materials. By inducing a magnetic field in the material and applying iron particles, our skilled SUBSEA NDT & Engineering technicians can identify flaws like cracks and fractures, as the particles accumulate at points of leakage.

MT is commonly used for inspecting welds, pipelines, and critical structural components in offshore and industrial environments. Our team’s precision ensures that any potential flaws are identified early, helping prevent failures in mission-critical assets.

Advanced Nondestructive Testing

Our Advanced Non-Destructive Testing (NDT) services harness cutting-edge technologies to provide deeper insights and unparalleled accuracy in asset inspection. Our suite of advanced methods includes Phased Array Weld Inspection for high-precision weld evaluations, Automated Ultrasonic Corrosion Mapping for comprehensive material integrity assessments, Surface Eddy Current Array for detecting surface and near-surface defects, Low-Frequency Electromagnetic Testing for examining corrosion in piping, and Digital Radiography for high-resolution imaging of complex components. Each of these advanced techniques is designed to address challenging inspection needs with efficiency and precision, ensuring that our clients receive the most reliable data to maintain asset integrity and safety.

Automated Ultrasonic Testing (AUT)

Automated Ultrasonic Testing (AUT) for corrosion mapping is a highly effective technique for detecting and visualizing areas of material degradation. Using automated scanning equipment, AUT provides precise, repeatable measurements of wall thickness, enabling comprehensive mapping of corrosion patterns across extensive surfaces.

This method is especially valuable for monitoring large pipelines, pressure vessels, and structural components in high-risk environments. By capturing detailed data on wall loss and thinning, AUT helps clients identify critical areas of concern, plan preventive maintenance, and make informed decisions to extend the life of their assets while minimizing unplanned outages.

Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT) is a versatile and advanced NDT method that provides in-depth analysis of welds and material thickness for corrosion mapping. In code weld inspection, PAUT uses multiple ultrasonic beams to create high-resolution images of welds, enabling the detection of porosity, incomplete fusion, and other welding defects that can compromise safety.

For corrosion mapping, PAUT’s precision scanning provides detailed thickness measurements, allowing operators to pinpoint areas of corrosion with accuracy. PAUT’s ability to offer comprehensive imaging and data for both weld integrity and material degradation makes it invaluable for industries where asset longevity and reliability are essential.

Digital Radiography (DR)

Digital Radiography (DR) is a powerful tool for inspecting and imaging internal corrosion and weld quality in components where traditional visual access is limited. In profile corrosion detection, DR enables high-resolution imaging of piping and other assets, allowing technicians to accurately assess the extent of wall loss and any irregularities in the material profile.

For code weld inspection, DR provides precise, digital images of welds, identifying any discontinuities, porosity, or incomplete fusion that may affect structural integrity. The digital nature of this technology enables quick data processing, storage, and sharing, making it ideal for efficient, standards-compliant inspection in demanding environments like offshore platforms and refineries.

Low-Frequency Electromagnetic Testing (LFET)

Low-Frequency Electromagnetic Testing (LFET) is an advanced inspection technique designed to detect internal corrosion in ferromagnetic materials, such as pipelines. Using low-frequency electromagnetic fields, LFET can penetrate through coatings, enabling the inspection of critical components without the need to remove them.

This makes LFET an efficient and cost-effective solution for identifying and mapping internal corrosion, particularly in hard-to-access areas or in piping systems prone to internal corrosion. By providing accurate corrosion data without invasive procedures, LFET aids in proactive maintenance planning and helps prevent costly leaks or failures.

Pulsed Eddy Current Array (PECA)

Pulsed Eddy Current Array (PECA) is a specialized NDT method designed to detect corrosion and wall loss in ferromagnetic materials, particularly in situations where components are covered by insulation, coatings, or layers of corrosion products. PECA technology generates pulsed electromagnetic fields that penetrate these coverings, allowing technicians to assess material thickness and detect underlying corrosion without the need to remove insulation—a significant advantage in terms of efficiency and cost savings.

This method is ideal for inspecting large surface areas, such as pipelines and storage tanks, and provides reliable data even in hard-to-reach or harsh environments. PECA’s ability to deliver precise measurements through protective layers makes it a valuable tool for proactive maintenance planning and long-term asset management.
