Tata TGN Pacific Segment
1 Cable
The Tata TGN Pacific Seg. 1 cable comes off the beach flanking
the Nedonna cable landing station just north of Rockaway,
OR. The Seg. 1 cable connects Oregon to Emi, Japan. The Oregon
end of this cable was installed in June 2002. This cable is
routed north of the Garibaldi reef, south of the ‘shalepile’
and is thought to be buried throughout nearly all the fishing
grounds of bottom contact fisheries. The burial success rate
is over 99.8% on this cable. There is one small suspension
and exposure area in 242 fathoms of water located at 45º
45.791’ N 124º 46.308’ W. The cable is exposed
on the seabed for approximately 49 meters; of this, 19 meters
is suspended with a maximum height of about .5 meter. A second
area of cable exposure and suspensions occurs on the bottom
and east side of a canyon in water depths of 687 fathoms and
deeper. The center of this .3 nm area of four small suspensions
is 45º 47.427’ N 124º 53.157’ W. These
suspensions vary in length from 17 to 43 meters long, and
from .3 to 3 meters in maximum height. Trawlers are advised
not to tow over either suspension area and to use caution
when fishing near them.
Tata TGN Pacific Segment 5 Cable
The Tata TGN Pacific Seg. 5 cable begins in Rockaway Beach, Oregon
and lands in Hermosa Beach, California. Seg. 5 was the first
cable to be installed off Oregon as part of the Tata TGN Pacific
cable system. The cable exits a bore pipe that is about .6nm
north of the Twin Rocks and about .6nm off the beach. The
cable route heads in a Southwesterly direction, south of the
Garibaldi Reef and the Southern Cross Cable to a point about
5 miles offshore of Cape Meares, where it turns to a WSW direction.
This cable is believed to be buried from just outside the
bore pipe to 764 fathoms water depth, offshore of the current
trawl fishing grounds. Seg. 5 was installed in the waters
off the coast of Oregon in November and December of 2001.
A very high rate of successful burial was achieved on this
cable installation, with burial of nearly 99.9% of the cable
that was intended to be buried. There are no restrictions
in currently trawled areas on this cable.
Tata TGN Pacific Segment 6 Cable
Tata TGN Pacific Segment 6 cable exits from the southern of two
bore pipes that were horizontal directional drilled (HDD)
from east of the beach dune in Rockaway, OR. The Seg. 6 cable
crosses Tata TGN Pacific Seg. 5 cable just west of the bore pipe
then follows the Tata TGN Seg. 5 cable alignment off the continental
shelf, staying north of the Seg. 5 cable. This cable was installed
in August of 2002. We believe Tata TGN achieved 100% burial in
the current trawl grounds on this installation. In much of
the fishing grounds, the cable is buried over 4 feet into
the seabed. This cable terminates near Toyohashi, Japan. There
are no trawl restrictions in effect on this cable.
 OFCC Agreement on TGN Cables
The Tyco cable system was purchased by Tata Communications and is now known as Tata Global Network (TGN).
