COLOMBO DOCKYARD DELIVERS CABLE LAYING VESSEL

KDDI Cable Infinity is the largest vessel constructed by Colombo Dockyard to-date. Built for worldwide, subsea operation based on a VARD Design and to ClassNK classification society standards and JG requirements, the vessel will undertake cable installation and repair works of optical and power cables.

“The delivery of this modern-day highly sophisticated Cable Laying Vessel is testament to the pride and dedication exhibited by Colombo Dockyard’s shipbuilding team. It demonstrates Colombo Dockyard’s proven capability to design, construct and deliver large, complex vessels to international markets as well as domestic market.” Says Mr. D.V. Abeysinghe MD/CEO of Colombo Dockyard.

The vessel features diesel-electric propulsion and DP2 positioning. The vessel’s forward tank has been fitted with an underdeck cable carousel and spooling system, with a payload capacity of 2000 tons, a loading arm and a control cabin.

The ship will be operated by KDDI’s wholly-owned subsidiary Kokusai Cable Ship Co (KCS), and her scope in subsea installation and engineering assignments includes work in the Asia Pacific region’s fast-growing offshore windfarm industry.

The vessel is diesel electric-driven and has optimised power provided by four generator sets, each generating 2,300 kW. Three out of the four generators on board are sufficient to cope with the highest propulsion power demands, ensuring high reliability with a bollard pull of up to 80 tons.

Propulsion is achieved through two azimuth propellers in the aft and two tunnel thrusters and one retractable azimuth thruster in the forward. All five thrusters on board the vessel are controllable pitch propelled with variable RPM, permitting the pitch and RPM to be optimised.
