integrity and structural safety. By transcending barriers of
inaccessibility and risk, these techniques not only serve as
sentinels for human lives but also as pillars of efficiency
and reliability in safeguarding critical infrastructure. In
today's engineering landscape, where once-unthinkable
feats are now within reach, remote NDT stands as the
vanguard of innovation, ensuring the enduring durability of
our most essential assets.
Common Defects in the Oil & Gas Industry
Remote NDT techniques play a vital role in the Oil and gas
industry, where safety and environmental consideration is
of utmost importance. Some common defects in the oil and
gas industry that may require testing using remote NDT
methods include:
Ú Corrosion:
ë Corrosion is a persistent issue in pipelines and other
equipment in the oil and gas industry. It causes a
deterioration in the state of the material, due to
gradual chemical reactions with the surrounding
environment and materials carried by the pipelines.
ë Corrosion weakens the structural integrity of
pipelines, potentially leading to leaks, spills, and
catastrophic failures that can have severe
environmental and financial consequences.

Corrosion in pipelines in the form of rust
Techniques such as ultrasonic and radiographic
testing, enable inspectors to assess the extent of
corrosion without the need for human entry, making
it safer and more efficient. By employing drones or
robotic systems equipped with NDT sensors,
operators can identify corrosion spots in remote or
inaccessible areas.
7 Weld Defects:
Welding operation being performed on a workpiece
Welding defects, including cracks, porosity,
incomplete fusion, and lack of penetration, can
compromise the strength and integrity of welded
joints in pipelines.
Weld defects can lead to fractures and leaks, posing
safety hazards and environmental risks, especially
in oil and gas pipelines.
Remote NDT methods like radiographic and phased
array ultrasonic testing are used to inspect welds in
pipelines. Welds are assessed for their adherence to
industry standards using remote inspection via
advanced sensors and equipment.
Hydrogen-Induced Cracking (HIC) and Stress
Corrosion Cracking (SCC):
HIC and SCC are forms of corrosion that can occur in
pipelines due to high levels of hydrogen and tensile
stress, respectively.
These defects can cause brittle fractures in pipelines,
leading to leaks, ruptures, and accidents, posing
significant risks in the oil and gas industry.
Stress corrosion cracking in a workpiece
Remote NDT techniques, such as electromagnetic
acoustic transducers (EMATs) and guided wave testing,
are used to identify HIC and SCC in pipelines. Remote
inspections provide a safe and efficient means to detect
these defects in challenging environments.
7 Erosion and Abrasion:
Erosion and abrasion result from the physical wear
and tear of pipeline surfaces due to the flow of
abrasive materials, such as sand and solid particles.

Erosion and abrasion can thin pipeline walls,
reducing structural integrity and potentially leading
to failures and leaks.
Edge erosion in a pipe
Methods including remote-operated robotic
platforms equipped with ultrasonic or eddy current
sensors, are employed to inspect pipelines for signs
of erosion and abrasion. These methods promote
operator safety during the structural assessment of
structures and equipment under study.
N Fouling and Scaling:
Fouling involves the accumulation of unwanted
materials on equipment surfaces while scaling
entails the deposition of minerals or scale.
Fouling and scaling reduce the efficiency of heat
exchangers, increase energy consumption, and can
lead to operational problems in the oil and gas
industry.
Remote NDT techniques, such as infrared
thermography and remote-operated drones, inspect
heat exchangers for fouling scaling. These remote
inspections help identify issues early, increasing
efficiency and reducing maintenance costs.
Scaling in a pipeline
N Material Defects:
Material defects, such as inclusions, voids, and
laminations, can occur during the manufacturing of
pipeline components, weakening the material's structural
integrity.
Material defects can lead to equipment failures and
safety hazards in oil and gas operations, especially
in pipelines.
Material defects in pipelines are detected using
remote NDT methods like Phased Array Ultrasonic
T
esting and Remote Visual Inspection. These ensure
meticulous testing in unfavourable environments.
Lamination defect in a steel plate

These defects and deformities in the oil and gas industry
emphasize the critical importance of regular NDT
inspections to detect and mitigate potential risks.
Neglecting such issues can lead to disastrous
consequences, including loss of life, environmental
damage, and financial repercussions.
Operational Scenarios Involving Critical
Remote NDT in the Oil Gas Industry
Using traditional NDT techniques in hazardous and often
inaccessible environments in the Oil and Gas industry can
pose various safety and environmental challenges. To truly
understand the merits of remote NDT, one must
understand the critical operational scenarios within the
oil and gas industry wherein the traditional, hands-on
NDT techniques fall short. These include the following:
l Offshore Platforms:
p Offshore oil and gas platforms reside in unforgiving
and corrosive environments at a significant distance
from the safety of the shore. These intricate
structures, replete with pipelines and equipment,
demand meticulous inspections.
p The offshore environment exposes equipment to
relentless saltwater, unpredictable weather
patterns, and the hazards of corrosion. Moreover,
the rigors of working at extreme heights and in
confined spaces are challenges that place human
inspectors at considerable risk.
l Subsea Pipelines:
p Subsea pipelines, submerged beneath the ocean's
depths, facilitate the transport of hydrocarbons
from offshore wells to onshore facilities. The
submerged domain necessitates inspections that
are both rigorous and remote.
p Subsea pipelines grapple with high-pressure
conditions, deep-water conundrums, and the
persistent threat of marine encrustation and
corrosion. Traditional inspections, due to the
constraints of underwater work, invariably entail
costly and logistically intricate diving operations.
l Refineries:
p Refineries house a labyrinth of equipment, tanks,
and pipes, each demanding frequent examination.
p Refineries operate at elevated temperatures and
under pressurized conditions. The dangers posed by
these circumstances are compounded by the
potential for exposure to noxious or flammable
gases, rendering human inspection perilous.
l Storage Tanks:
p Storage tanks, used to store refined petroleum
products, and chemicals, are critical for maintaining
the industry's ceaseless supply chain.
p These massive tanks may house corrosive or volatile
contents, a situation that demands their regular
inspection. Traditional inspections invariably entail
the laborious and costly process of tank emptying
and cleaning, disrupting operations and causing
financial setbacks.
l High-Risk Environments:
p Some oil and gas operations unfurl in high-risk and
remote locales, where the Arctic's biting chill or the
deep-sea's abyssal depth present unique challenges.
p The extremities of these environments, featuring
tempestuous weather, frigid temperatures, or far-
flung locations, conspire to make on-site inspection
an expensive, complex, and potentially life-
threatening endeavour.

How 3D Scanners
are replacing
Traditional
methods to
increase pipeline
inspection
efficiency,
reliability, and
safety
Challenges: Traditional pipeline assessment
methods are cumbersome, time-consuming and
limited
Without proper maintenance, the lifespan of pipelines can
be greatly reduced, which subsequently can lead to people
and the environment being exposed to potential hazards
as well as costly infrastructure investments and network
downtimes. In order to safeguard against pipeline defects,
corrosions and failure, pipeline operators and owners as
well as non-destructive evaluation (NDE) service
providers must carry out preventative pipeline integrity
assessments on both greenfield and brownfield projects.
Traditionally, pipeline inspections were inherently complex
and challenging, due to field conditions and safety
considerations. Systematic monitoring requires skilled
inspection technicians that were often difficult to find.
In addition, non-destructive testing (NDT) on pipelines
traditionally entailes manual measurement techniques, such
as paper rubbings, vernier depth gauges and single-line
lasers. Such techniques were exceptionally time-consuming
and cumbersome—and inevitably ramped up operational
costs while limiting pipelines being able to operate at full
capacity. What’s more: many issues arose regarding the
accuracy, reliability repeatability of manual inspections in
harsh pipeline environments. Characterizing a pipeline’s
material integrity means looking for signs of internal,
external atmospheric corrosion as well as mechanical
damage, such as dents and gouges. The vast amounts of
data collected could mislead technicians to either
recommend overly conservative remedial actions, which
impacted network availability, or assess that pipes were still
fit for service when they were not.

Do pipeline assessments require experts with a
lot of experience?
The need for inspectors is growing annually as pipeline
operators and owners expand their networks. In today’s
tight labor market, finding qualified pipeline inspectors
with all the necessary training as well as the right know-
how on a variety of different conventional measurement
techniques and tools is extremely difficult. Training
technicians to become certified pipeline inspectors can be
a long and costly endeavour.
Even after they are trained, technicians are not immune to
human error or capturing poor data. Due to the harsh
working conditions, turnover is extremely high. Solutions
are therefore required to address these inspection staff
issues.
Are pipeline inspections extremely long?
Pipeline owners and operators follow specific protocols
when conducting pipeline assessments. Using manual
inspection techniques requires lengthy tool setups and
measurement times that could span hours or even days,
depending on the length of the pipe.
Once the data is collected, extra time is needed to evaluate
the measurements on site and send them to off-site
engineers or other specialists further assessments.
How accurate are pipeline assessements?
Pipelines are inherently complex—and so is inspecting
them in the field for damage, such as corrosion, weld arc
strikes, stress- and atmosphere-induced cracking, gouges
and dents. Traditional techniques being manual meant that
the accuracy, reliability and repeatability were dependent
on a technician’s skill and often compromised by the
surrounding environment on any given inspection day.
In addition, inspection teams may miss out on some
important information or damage. If the pipe is buried
back, it is too late for technicians to go back and make
further assessments. This means that inspectors and
integrity engineers may question the accuracy and
availability of the data—and lack the confidence in
providing their final recommendations.

Solutions: Handheld 3D scanners change the
game for quality pipeline integrity assessments
With handheld 3D scanners, pipeline operators and
owners as well as NDE service providers can benefit from
an easy-to-use, fast and effective tool for all types of
pipeline integrity inspections.
Handheld 3D scanners make convenient to acquire
measurement data on pipes of up to 18 m (60 ft)—and
directly at a pipeline’s specific inspection quadrant.
Easy-to-use, 3D scanners, along with their self-positioning
and dynamic referencing capabilities means anyone can
perform a pipeline inspection. No metrology experience or
extensive training on a series of measurement techniques
required!
Thanks to their optical technology, 3D scanners acquire
measurement data fast, which reduces inspection times.
Imagine being able to achieve up to 1,300,000
measurements per second!
3D scanners generate highly accurate, repeatable and
reliable results with exceptional resolution, regardless of
user ability, the complexity of the pipeline’s geometry,
unstable excavation environment, and measurement setup
quality. With an accuracy of 0.025 mm and ISO 17025
accreditation, 3D scanners can help integrity engineers
and inspectors to confidently make the right decisions.
Benefits: Transforming pipeline assessments for
the better!
After having conducted its field tests with Creaform’s
HandySCAN 3D scanner and VXintegrity-Pipeline NDT
software, pipeline owners and operators immediately
notice the solutions’ undeniably positive impact on
pipeline inspection workflows and results.
