BATTERY POWERED REMOTE ACCESS
CRAWLER WITH A DRY COUPLED
ULTRASONIC WHEEL PROBE.
The Scorpion2 dry coupled remote access ultrasonic crawler
system brings major inspection efficiency improvements to
above ground ferro-magnetic structures such as storage tanks,
vessels and offshore installations.
The all-in-one solution has been developed with feedback from
Silverwing’s extensive Scorpion user base and support from
industry leading robotics researchers at Strathclyde University.
Performance advantages include faster data collection, efficient
scanning patterns, higher probability of detection and the ability
to collect valuable measurements in critical locations enhancing
RBI inspection programs.
PROBE DESIGN
Silverwing’s unique “Dry Coupled” ultrasonic wheel probe
eliminates the need for traditional couplant or a constant water
supply. The wheel probe performs like a standard twin ultrasonic
probe, and can measure material thickness from 5 mm to 100 mm,
including through paint.
The probe is enclosed in a gimballed probe carriage allowing it
to ride over protruding objects whilst keeping it perpendicular
to the inspection surface. The carriage also allows the system to
record thickness measurements within 25 mm of a weld cap to
inspect the critical heat affected zone (HAZ).
The system has two operating modes and can record thickness
measurements at a speed of up to 125 mm/sec in programmable
mode and up to 150 mm/sec in manual mode, this brings a
major inspection efficiently improvement which will translate into
increased revenue for its users.

INSPECTION STANDARDS
Traditional techniques of random tank shell thickness measurements can be
very misleading due to the low Probability of Detection (POD) and may lead
to incomplete corrosion rate calculations. As recommended by EEMUA, the
Scorpion2 records thickness measurements along a vertical line even in the
critical Heat Affected Zone (HAZ) meaning a higher POD resulting in a more
accurate corrosion assessment.
EEMUA states that walking on tank roofs can be hazardous if the condition
is not known. The condition and thickness of the roof plates should be
confirmed before access is permitted. The Scorpion2 can remotely record
thickness measurements reducing the need for roof access.

DATA CAPTURE SOFTWARE
The Scorpion2 system is supplied with four intelligent Li-ion
batteries allowing for continuous on-site operation. (two for the
Scorpion2 and two for the UTLite2). Each Scorpion2 battery can
scan up to 700 metres from a full charge or the equivalent of 8
scans of a 40 metre high storage tank.
The Scorpion2 B-scan software features several powerful
data review, reporting and printing tools. Saved data can be
reviewed at any time with active A-scan and B-scan displays.
Placing the cursor over any part of the B-scan profile shows the
A-scan trace for that specific section of the scan.
The Scorpion2 swappable battery is mounted on board the
crawler removing the need for a separate battery pack on the
ground thus reducing umbilical and overall system weight.
An adjustable reporting threshold indicator can be displayed
over the B-scan profile, this helps to identify reportable defects
at a glance and allows rapid analysis of the complete scan. The
full amplitude B-scan mode helps to characterise wall loss which
in turn allows for a more detailed post-inspection analysis and
accurate corrosion assessment.
ACTIVE STEER
One of the challenges for crawlers is compensating for drift
on high structures, especially in windy conditions where
the umbilical can drag the unit offline. Active Steer solves
this problem with the use of dual encoders to measure
angle changes, then automatically corrects the scan path by
controlling each of the four drive wheels independently.
Active Steer also allows for accurate positioning when turning
the crawler through programmable angles making it easier and
more efficient for the operator.
DRIVE WHEELS
The Scorpion2 uses four independently powered magnetic
drive wheels with treaded tyres for ultimate grip in damp
conditions. The treaded tyres give the Scorpion2 the advantage
of being able to easily drive over 12 mm steps with less slippage
compared with other systems on the market.

CMAP REPORTING SOFTWARE
Silverwing’s CMAP software is an innovative solution to
managing today’s complex inspection data. CMAP has the
potential to save many hours on an average inspection with the
ability to import, analyse and report inspection data collected by
multiple vendors and multiple inspection techniques.
The Scorpion2 works seamlessly with the UTLite2 ultrasonic data
acquisition unit. Simply connect the Scorpion2 to the UTLite2 via
the umbilical cable and you’re ready for your inspection.
Users of CMAP can import and stitch together inspection data
collected by the UTLite2 acquisition unit which includes the
Scorpion2, R-scan and Thetascan as well as Silverwing’s RMS2
and Floormap.
The intuitive touch screen control software has been designed
for the operator, large buttons and simple to use menus ensure
easy crawler control and ultrasonic setup.
CMAP allows for the analysis of these various inspection
datasets on one screen creating a complete view of an assets
condition with full traceability back to raw inspection data.
