Global Marine Systems Limited, the
world leader in subsea system
design, installation and
maintenance has been awarded
for North America Maintenance
Zone (NAZ) submarine cable
maintenance contract up to 31st
December 2024. This long-term

deliver highly responsive and well-
executed maintenance provision to
all members.

TECHNOLOGY

Wave Venture from the 1st February
2017, bringing improved DPS-2

strategic spares in its cable tanks to
support

rapid mobilisation in the event a fault and
is equipped with COTDR and deep
water ROV capability to support the
detection of faults on ultra-long haul
systems.

ZONE RANGE
NAZ covers a cable maintenance
footprint, which stretches from the
Eastern North Pacific to the Equator.
Global Marine has been providing cable
maintenance services from its base port
in Victoria, British Columbia, Canada
since January 2012 providing dedicated
year-round cover to the region. Global
Marine’s track record in the North Pacific
extends back further, when in 1991 it
installed and maintained the first
repeatered system linking the US
mainland with Japan.
