Wire & Cable ASIA – July/August 2013
JDR has deployed subsea production
umbilicals and power cables for the
China National Offshore Oil
Corporation’s (CNOOC) Liuhua 4-1
field subsea tieback project.
JDR designed and manufactured over
42km of ESP power cable, each
incorporating nine power cores,
delivered in three 14km lengths.
The order also included a 14km main
production control umbilical and a
bridging manifold control umbilical.
These umbilicals are operating in the
South China Sea, at depths from 260m
to 300m.
Paul Gahm, JDR VP sales and
marketing, said: “CNOOC has utilised
the full range of JDR’s capabilities in
subsea umbilical design and
manufacture to deliver against their
objectives on this major project.”
He added: “We designed CNOOC’s
umbilicals to maximise reliability,
minimise project cost and provide the
customer with future-proofing options.
For example we produced the ESP
power cables on our vertical lay-up
machine (VLM) in Hartlepool.
“This enables us to provide ultra-long
length electric power cores, which
significantly reduces the number of
core splices required.
“And the design approach we have
taken will support future field
expansion, with the ability to serve up
to four additional wells. We loaded out
the project, via transpooling, straight
onto a heavy lift vessel via the
deepwater port alongside our
Hartlepool plant.”
Each ESP power cable includes three
3-phase power circuits, capable of
serving three identical ESPs in this
eight well field.
