NTT Communications, NTTWEM and NTT FINANCE Launch New Submarine Cable-Laying Ship "Kizuna"
NTT (News - Alert) Communications Corporation (NTT Com), the ICT solutions and
international communications business within the NTT (NYSE:NTT) Group,
NTT World Engineering Marine Corporation (NTTWEM) and NTT FINANCE
CORPORATION (NTT FINANCE) jointly held a launch ceremony today for their
new submarine cable-laying vessel "Kizuna" at Kanrei shipyard in
Tokushima, Japan. Construction of the 8,500 ton ship, which measures 109
meters in length and 20 meters in width, and which will have a planned
average cruising speed of 13 knots and a capacity of up to 60 crew, will
be completed by the end of fiscal year 2016.
Kizuna will be owned by NTT FINANCE and leased to NTTWEM when required.
NTTWEM's parent company NTT Com and other telecommunication companies
and service providers will utilize Kizuna and three other vessels
operated by NTTWEM to lay and maintain submarine cables used for
delivering network and cloud services.
Submarine cable forms part of the core physical infrastructure that
supports worldwide mobile communications, video distribution, music
sharing, the transmission of enterprise data and IoT-related data
collected from sensors worldwide. Optical fiber undersea cables are
increasingly being laid to handle the ever-increasing volumes of such
data.

Features of the new vessel include:
-
Good navigability and ability to remain stable over fixed points in
the ocean
Kizuna is configured with its main working space
in the stern. Its advanced design incorporates azimuth propellers, an
electric propulsion system and a dynamic positioning system. These
allow it to navigate quickly to selected locations and once in
position, to withstand wind velocities of up to 14 meters per second,
wave heights of up to 3 meters and ocean currents of up to 3 knots.
-
Remotely Operated Vehicle (ROV) allows rapid laying of undersea cable
An
ROV equipped with a jet cable laying system and with a maximum
operating depth of 2,500m will be deliverd as part of the new
vessel's equipment. This will allow rapid troubleshooting, speedy
determination of any points of failure and easier replacement of cable
following any repairs.
-
Multipurpose vessel with a variety of modern equipment
The
new vessel will have a large open working deck with two heavy-duty
cranes and a large secured work space at the stern, allowing it to be
deployed for a variety of tasks, including cable maintenance as well
as cable laying.
-
Compact design will allow cable maintenance in domestic waters
Careful
use of space and the extensive deployment of electronic equipment will
allow small teams of people to carry out more routine maintenance work
efficiently. Kizuna is smaller than its existing sister ship "Subaru,"
making it suitable for work within congested Japanese waters.
-
Flexible functionality will facilitate rapid disaster response
Kizuna
has been designed to assist during disaster recovery operations, for
example through the rapid shipment of containers and other supplies.
The vessel can also transport disaster recovery vehicles and emergency
cellular network base stations, as well as satellite communication
facilities and temporary accommodation for NTT group employees working
in disaster zones (see Appendix
1).
NTT Com plans to deploy the new ship Kizuna predominantly for cable
laying in Japanese waters, with the existing Subaru being used mostly
overseas, with both vessels offering fast and competitive undersea cable
laying and maintenance.
The name of the new vessel was chosen following an internal poll of NTT
Com Group employees. The Japanese word "kizuna" signifies the connection
between people and between people and things, and is therefore an
appropriate symbol for NTT Group's business field, as well as being a
keyword for the next generation. The calligraphy of the Japanese
character for "kizuna" appearing on the ship's body is the work of
Tetsuya Shoji, President and CEO of NTT Com.
