Colombo Dockyard, a joint venture between the Sri Lankan government and Onomichi Dockyard, has delivered a modern cable layer to Japan’s Kokusai Cable Ship. This is the biggest ever vessel, price- as well as lengthwise, built by the yard in its history.
The 5757 dwt KDDI Cable Infinity is 113.1 m in length, 21.5 m in breadth, has a top speed of 14.5 knots and accommodation for 80 people onboard. The vessel offers a bollard pull capacity of 80 tonnes, with a range of 10,000 nautical miles, and has Dynamic Positioning capability to Class 2 standards. The basic design and production drawings for the newbuilding were supplied by VARD Designs and the vessel is built to ClassNK classification society standards.
Designed for subsea operations, and in particular the installation and repair of both optical and power cables, the vessel offers a high degree of operational flexibility. For handling power cables, the forward tank has been fitted with a carousel system and a spooling arm.
The vessel is designed and equipped with a focus on good sea keeping ability and station keeping performance. Passive roll reduction tanks help minimise the effect of ship rolling, for example, while low resistance hull lines provide for higher levels of speed and lower fuel consumption than normal. The vessel is claimed to be extremely eco-friendly, being diesel electric driven.
