A cable-laying vessel operated by Chinese offshore construction company the Dejing Group has completed undergoing a two-month modernisation program to enable it to better serve customers in the domestic offshore wind market.

The upgrade on the 2021-built Dejing 106 included installation of a dynamic positioning system and further optimisation of the anchor positioning system and the cable loading equipment.

The upgrades will enable the vessel to perform cable-laying using DP and anchor positioning simultaneously if required. Cable-laying can be performed even under Beaufort Force eight conditions, 3.5-knot ocean currents, and 2.5-metre wave heights. The maximum cable-laying depth is set at 50 metres.

The 106- by 33-metre, 7,106-tonne vessel is also equipped to perform maintenance and emergency repairs on cables. The deck can carry up to 8,000 tonnes of cables while a powered rotating cable pool ensures more efficient deployment and installation. The pool can deploy both 220kV AC and ±400kV DC cables.

The upgrade works on Dejing 106 were completed by Nantong Yongxing Shipbuilding in compliance to China Classification Society requirements. The vessel will initially be deployed at offshore wind farm sites off Fujian and Guangdong provinces in southeastern China.
