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

The upgrade on Dejing 106 included installation of a dynamic positioning system and further optimisation of the anchor positioning system and the cable loading equipment. This will enable the vessel to perform cable-laying using DP and anchor positioning simultaneously if required, and to do so even in 3.5-knot ocean currents and 2.5-metre wave heights.

The vessel is also equipped to perform maintenance and emergency repairs on cables.

The upgrade works on Dejing 106 were completed in compliance to China Classification Society requirements.
