KDDI OCEAN LINK is a Japanese cable repair and cable‑laying vessel built at Mitsubishi Heavy Industries’ Shimonoseki Shipyard and delivered on 28 February 1992.

Technically, the vessel is classed by ClassNK with notation NS*(CL), MNS*, M0 and is fitted with twin controllable‑pitch propellers, bow and stern thrusters, and a Kongsberg Maritime dynamic positioning system. It has three main cable tanks with a total capacity of 2,300 m³ and is equipped with drum and linear cable engines, anti‑rolling tanks, and deck cranes to support cable laying, recovery, and repair operations. KDDI OCEAN LINK is primarily employed in the installation, burial, repair, and maintenance of optical submarine cables, supporting international communication networks across East Asia and broader regional routes. Operating under the Japanese flag and typically based around Yokohama and other Japanese ports, it serves as part of KDDI’s subsea telecoms infrastructure fleet alongside newer units such as KDDI Cable Infinity.
