Nexans has been awarded a €6 million contract by Sevmash,
Russia’s largest shipbuilding company, to develop, manu-
facture and supply low-temperature and ice-resistant
control, instrumentation and power cables for the marine ice-
protected Prirazlomnaya stationary oil production platform in
the Barents Sea.
The Prirazlomnaya platform has been specially constructed
for the development of the Prirazlomnoye oil field and is the
first oil production project on the Russian Arctic shelf. The
area is characterised by extremely low temperatures and
high ice loads. Ice-free for only 110 days a year, the annual
average temperature is –4˚C while winter temperatures can fall
to –50˚C.
The severe operating conditions require a unique combination
of marine cable technologies to provide low-temperature
resistance with fire-resistant, low-smoke and halogen-free
properties.
Around 850km of the special cables for Sevmash will be
produced in the specialised facilities of Nexans Kukdong Electric
Wire Co, Korea. Production has already started, and deliveries
will continue until the end of 2011.

Ice-resistant cable contract for
the Barents Sea
The acid-free DCCD (dry cleaning, coating and drawing) process
incorporates lubricant viscosity control that enables demanding
wire qualities to be drawn in an economical way, at the highest
speed. The system replaces conventional rod preparation
(chemical cleaning, rinsing, wet pre-coating and drying) in all
direct drawing applications from rod to wire, including 0.85 -
0.88%C mechanically descaled bare rod, without pre-coating
chemicals. The result is lower cost, improved wire quality and
environmental benefits.
The critical aspects of lubrication, friction and wear, part of
the complex wire drawing mechanism, are greatly simplified
and some problems, such as wire breaks, surface damage and
excessive generation of metallic fines, are virtually eliminated.
Instantaneous rod dry coating, operating with no speed limit
and at zero energy consumption (self-generated by the LVC/
PDH unit), enables an automatic control of crucial variables,
including liquefied lubricant thermal stability, a vital parameter
that prevents metal-to-metal contact at the wire-die interface.
This allows high drawing speed and wear performance of
0.1–0.3 micron per ton of wire drawn.
Full film consistent coatings are achieved in a range from a
strongly adherent hard multi-coat layer for high-tensile spring
wire or PC strand wire, to an ultra thin nano-coat water-soluble
film for plating wire.
Benefiting from the recent development in rod dry preparation
and wire lubrication mode, the DCCD process provides
reliability and potential for improved steel wire production.
