With successful harbor trials now complete, MJR said it will now demobilize the equipment and prepare for instal- lation on an operational offshore wind farm substation in the North Sea. The company did not say when the system would be installed offshore.
In addition to charging CTVs, with a maximum charging time of two hours, MJR said it was also developing a simi- lar system delivering higher powers for providing offshore power and charging for larger vessels, including SOVs.
