when designing thermowells for
petrochemical applications. The risk
of a thermowell failing due to under-
engineering, or the extra costs incurred
by the end user because of an over-
engineered thermowell, can both
be avoided if the buyer works with
a reputable, experienced thermowell
supplier such as OMC.
Mr Chant concluded: “Okazaki has
been providing technical support and
design services to the oil, gas and
petrochemicals industry for many years
now, working to Japanese standards,
which are often more stringent than the
ASME equivalent. Therefore, for Okazaki,
the new standard simply reinforces
that what we’ve been providing our
customers with for many years is the
best approach.”

Magnetic Analysis Corp (MAC) has
recently supplied several Rotoflux
®
flux
leakage inspection systems to major
producers of oil country tubular goods.
Designedtomeetthelatestspecifications
in the oil and gas industry, including API
5CT and 5L, ASTM, and ISO, these
transverse and longitudinal flux leakage
systems can handle material from 76.2
to 406mm (3" to 16") diameter.
Flux leakage technology is particularly
applicable for inspection of heavy wall
material, and MAC’s multiplex test
probe systems allow operation at high
throughput speeds. Using very high
magnetising capabilities and selective
filter circuits, transverse and longitudinal
defects on the OD/ID such as rolling
skins, laps, cracks, laminations and
cavities as well as internal defects can
be accurately detected.
Electronics mounted in the longitudinal
rotary test head provide up to 24
separate channels from 24 test probes
and allow each individual signal to be
independently filtered, displayed and
processed. For detecting transverse
defects, multiples of 12 element probe
arrays are individually mounted to rotate
to provide 100% coverage, based on
the tube size.
Production line testing of OCTG from MAC
Especially important for many OCTG
producers is the ability of the Rotoflux
systems to handle tube with upset,
irregular shaped ends, and tube with
couplings. Specially designed test probe
assemblies are automatically controlled
to retract when the end of a tube with
a coupling, upset or irregularly shaped
end approaches the rotary test heads.
To meet even more demanding
specifications for OCTG, many producers
are using a comprehensive inspection
system that includes both the Rotoflux
and MAC’s Echomac
®
ultrasonic test
systems. The Echomac systems include
MAC’s FD-4 electronics with up to 32
independent test channels, suitable
for user configured flaw detection or
thickness gauging for each channel, and
the Echomac UT rotary to maintain higher
throughput speeds. Current UT rotary
models can handle material ranging from
6.35 to 360mm (¼" to 14").

Technip wins prestigious
2010 Global Pipeline Award
Technip has been awarded the 2010
Global Pipeline Award in the field of
Pipeline Transportation during the
International Pipeline Conference
in Calgary, Canada, for its Subsea
Cryogenic Pipe-in-Pipe Pipeline Transfer
System (C-PiP).
The American Society of Mechanical
Engineers International (ASME) Global
Pipeline Award was presented to Technip
by members of the Pipeline Systems
Division, a division of the International
Petroleum Technology Institute (IPTI).
Technip began development of the C-PiP
Pipeline Technology in 2004, earned
proof-of-concept certification by ABS
and BV in 2006, and fitness-for-service
certification fromDNV in 2008. Technip is
currently designing or has assessed the
potential for C-PiP Pipeline applications
in several projects.
The award application featured the
design for the Hess LNG Weaver’s
Cove Energy project in Fall River,
Massachusetts. Technip’s C-PiP
technology was selected for this
liquefied natural gas import terminal
project based on its superior safety
and reliability features. The C-PiP
LNG transfer system was engineered
to address the specific challenges of
this project’s location and is currently
proposed for the 4.25-mile (6.8km) long
offshore berth.
