Technology spotlight

Heavily corroded and difficult-to-accesspipelines
VECTRA™ GEMINI HD and MagneScan™ SHR Plus
are our highest-specification in-line inspection tools.
They deliver the best possible information to address
your most complex challenges—enabling morereliable decision‑making, ultra-high confidence,and significantly fewer digs. VECTRA HD has twice
as many sensors as other MFL tools. The result is amore accurate picture than ever before—one thatenables early detection and pinpoint accuracyof even the smallest instances of metal loss andcomplex corrosion. MagneScan SHR Plus has 4-in-1
sensor technology that makes it possible to identify
linkages between individual pits/pinholes and theformation of NAEC as well as circumferential slotting
and grooving. These tools deliver extremely highaccuracy for depth, length, and width—making
them particularly well suited to lines with extensive
complex corrosion, high failure consequences, or the
likely presence of axial defects or pinholes. The end
result is the high confidence needed to only dig andrepair what is absolutely necessary—the savings here
significantly outweigh the incremental cost of thehigher‑specification inspection.

Pinhole corrosion

Pilferage and illegal tapping

Very small pinholes can cause major problems—
leaks. Whether caused by external microbe-induced
corrosion or internal pitting, pinholes are always
extremely difficult to detect. Our highest-definition
tools have the capability of detecting pinhole-sizedfeatures, and seeing the most minute areas of metal
loss. VECTRA HD, for example, has industry-leading
sensor resolution, and yields multiple data sets ina single run—resulting in a sharper view that moreaccurately locates, identifies, and sizes complex
anomalies such as pinholes. On top of inspection
tool capabilities, we’re constantly improving ouralgorithms and models so our analysts can moreaccurately quantify these difficult features. All in all,your advantages are reduced maintenance costs
and less lost revenue, in exchange for increased
uptime, fewer digs, and improved safety.

When two illegal taps were discovered in a
European refined-product pipeline (along with atank holding 30,000 liters of stolen product), wequickly mobilized a MagneScan tool to assess theunknown risks. We compared the results to another
MagneScan inspection we completed severalyears earlier. Within a week, we produced a highly
practical Change Report that gave precise location
details about new anomalies. We identified nineillegal taps along nearly 200 km of pipeline. Six
months later, we ran the process again and foundseveral new illegal taps. Not only has this helped
the customer minimize its losses, but it’s raised
industry awareness and vigilance around thiscritical financial and safety issue. We now offer theChange Report with our MagneScan SHR Plus andVECTRA GEMINI HD inspection services.

MagneScan HR & SHR

Our corrosion and metal-loss integrity solutions date back to the development ofmagnetic flux leakage tools in the 1960s. Now, with over 2 million km of pipeline inspectedworldwide, our advanced technologies, engineering experience, and data-interpretation
capabilities are all well proven in helping operators meet increasingly stringent regulatory
requirements—while enhancing the safety and productivity of their assets.
From the moment a pipeline is commissioned, it begins to deteriorate. No matter whichcathodic protection system or coatings are used, or what product is in the pipeline,
corrosion will eventually compromise pipe wall integrity. We provide the accurate defectdetection, sizing, and classification to efficiently prioritize necessary maintenance,
determine growth rates, and plan future inspection. Each of our technologies offers uniqueadvantages, so the selection decision can be closely aligned with the underlying threats
and your objectives.
All our inspection services have one thing in common: they ensure that, through better
accuracy performance, you save more money by repairing only what you need to repair.

Offshore heavy-wall pipelines
Offshore pipeline inspections can be much more
complicated than onshore inspections, as multiple
pipes are often clustered together on the platformand subsea. Their close proximity and adjacentpipe walls can confuse some inspection tools. But
that’s not a problem for our MagneScan SHR Plus
technology. For example, MagneScan identified acritical feature of around 80% wall thickness that was
extremely difficult to analyze and verify because of
its location at a transition between spools of different
wall thicknesses, and directly behind the caisson wall.
This resulted in lower than expected magnetic fieldlevels for the known wall thickness. To be certain, weworked with the client to design highly specialized andrigorous pull-through tests to verify that the defectwas indeed below the critical 85% wall thickness thatwould require shutdown. The tests confirmed the tool’s
accuracy, and the client was able to keep operating
the pipeline until a replacement line was constructedwith substantial cost savings.

Baseline and routine inspection
Whether an operator is looking for reliable baseline
surveys or routine inspections, our MagneScan HR &SHR tools continue to be among the go-to solutions
for most customers around the world. The technology
provides accurate and reliable corrosion inspection,
which enables the integrity management programs of
most pipeline operators. Robust designs and extensive
track records result in industry-leading first-run
success rates; and they also have a combination ofinspection options. Geometry and pipeline mapping
can be added to a metal-loss inspection to simplify
operations. Furthermore, the latest-generation
MagneScan tools provide an additional option toincrease detection and sizing specifications, which areparticularly valuable for pipelines with higher incidenceor complexity of corrosion.

Axially oriented seam corrosion

Cracks in girth and spiral welds havebeen causing operators concerns for anumber of years; but finding a reliableinspection solution has been challenging.
Advancements in our MagneScan and
VECTRA technologies have led to increased
confidence levels in detection and sizing ofthese features with MFL technology. We’ve
gathered a large database of actual pipeline
defects, alongside manufactured defects,
to develop a bespoke analysis process
and associated report specifically for girthand spiral welds. This is now proven to bea reliable solution for operators who know
they have pipeline construction concerns,
and need to better focus their integrity andmaintenance budgets.

For over 20 years, our TranScan inspection fleet
has been the industry go-to for detecting seamweld defects, axial flaws, and third-party damage.
TranScan’s transverse field inspection (TFI) technology
ensures that axial flaws (cracks and elongatedmetal loss) present their largest dimension to themagnetic flow, creating a strong signal from flaws
that are invisible to other magnetic tools. TranScan
tools are very robust, and equally at home in gas oroil pipelines. They can inspect up to 4 m/s and havea high tolerance to dirt and wax. They have evenbeen used to detect flaws in seam welds as narrowas 0.1 mm. TranScan has become the tool of choiceamong operators and regulators for the detection ofhook cracks and lack-of-fusion in pre-1970 ERW gaspipe. Its sensitivity to dents, associated cracking, andmetal loss also makes it ideal for the detection andclassification of third-party damage.

Corrosion management andresponse planning
It’s industry standard to compare datafrom different inspections to determine
corrosion growth rate, but the applicationof the resulting information is not wellunderstood. By contrast, our RunCom™
product provides a range of corrosiongrowth and integrity‑assessment services
that support response-planning decisions.
By moving away from fixed corrosion rates
to instead use joint-based and cluster rates,
we leverage the real power of RunCom’s
signal-level data analysis—this significantly
increases the precision of growth-rate
calculations, and improves decision-making
about re-inspection intervals and repair
initiatives. With excavation and repair costs
typically $100,000, RunCom’s ability to avoid
unnecessary digs has very clear value.

Our precommissioning and maintenance(P&M), and in-line inspection (ILI) teams
regularly join forces to provide a single pointof responsibility for complex projects. One
example of a successful combined effort
was for a German operator with a 22-day
shutdown planned to inspect two oxygen lines.
ILI in a water batch would be the easiest option,
but with a high cost. We instead proposed anitrogen batch, which was more complex—but

faster and less expensive. Bringing extensive
nitrogen experience to the table, we worked
closely with the customer and three suppliers
to manage everything from pre-engineering
to ILI and N2 execution, infield troubleshooting,and fast-track reporting. The team worked likea well-oiled machine, and the inspection wasa huge success with high accuracy from ourMagneScan SHR Plus tool.
