Wire & Cable ASIA – July/August 2013
news
THE largest infrastructure project in
western Europe, London’s Crossrail, is
a 118km high-speed rail link across
London.
Five tunnel-boring machines are
working 24 hours a day to produce
21km of twin-bore tunnels beneath the
city.
The tunnels are strengthened with
ArcelorMittal steel fibres. Over 11,000
tonnes of bespoke steel fibres are
being supplied from the ArcelorMittal
wire plants in Sheffield, England, and
Bissen, Luxembourg.
Crossrail’s eastern tunnels, from the
Limmo Peninsula to Farringdon, and
from Pudding Mill Lane to Stepney
Green, will use 4,000 tonnes of
ArcelorMittal HE++90/60 steel fibres to
reinforce the segments, and over 1,000
tonnes of HE+55/35 fibres in sprayed
concrete will be supplied to contractor
Dragados Sisk.
In the 2.6km tunnel from Plumstead to
North Woolwich, around 1,000 tonnes
of HE++90/60 steel fibres in segments
are being supplied to contractor
Hochtief Murphy.
ArcelorMittal’s WireSolutions fibres
sales team, technical support, research
and development, and production
teams worked together to supply the
steel for the contract.
They also worked with and provided
advice to the material engineers and
production managers in the three joint
ventures involved in the tunnel and
stations projects.
Two new grades of high performance,
high tensile strength steel fibre were
developed specifically for Crossrail.
The products, HE +55/35 and HE
++90/60, will reinforce the sprayed
concrete and tunnel lining segments.

Umbilical for offshore Malaysia
Nexans is making inroads into the Malaysia offshore sector with the award of
a major contract from Persada Engineering.
The French company is to supply a 22km electro/hydraulic subsea umbilical
for Sarawak Shell Berhad’s F29 field development.
The subsea cable will be installed at a depth of around 100m to provide
communication and control functions for the F29 field development.
The F29 umbilical will be manufactured at Nexans’ specialised facility in
Halden, Norway.
