- 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).
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.About NTT World Engineering Marine CorporationNTT World Engineering Marine has been the marine-engineering arm of the NTT family since 1998.
