Japan's NTT Com strengthens its underwater cable-lying capabilities
The internet connects people and things around the world. Optical cables placed along the ocean floor provide more than 99 percent of international communications. Together with NTT group companies, NTT Communications has recently outfitted the new submarine cable-laying vessel, Kizuna, to strengthen its underwater cable-laying and maintenance capabilities. The Kizuna prides itself with the capability to enable easy maneuvering and stable fixed point positioning in the ocean using DPS (dynamic positioning system). Its advanced design comprises two azimuth propellers, and an electric propulsion system, to allow lateral movement and the capability to turn in a small radius. Remotely Operated Vehicle (ROV) equipped with a jet cable laying system and with a maximum operating depth of 2,500m allows rapid laying and maintenance of undersea cables. The capabilities of the cable-laying vessel gained attention as it can perform different tasks on the ocean, particularly when the unprecedented earthquake struck Japan in March 2011. Kizuna is the first submarine cable-laying vessel equipped for the dual purpose of serving as a disaster-relief ship in the case of major natural disasters. 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 employees working in disaster zones. A clock is indispensable for everyday life. 'Aoyama Times and Images Museum', a unique clock museum has opened in Aoyama, Tokyo. While looking at the watches made using various mechanisms, it can easily make the viewers forget the time.
