Will strengthen undersea cable laying and
maintenance capabilities in Japanese and overseas waters
NTT 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 oceanKizuna 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 cableAn ROV equipped with a jet cable
laying system and with a maximum operating depth of 2,500m will be
delivered 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 equipmentThe 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 watersCareful 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 responseKizuna 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.
