DELPHINE © CLdN

CLdN has announced that the DELPHINE successfully completed its first voyage since the fire incident on 16 April, operating an overnight trip from Zeebrugge to Killingholme. The vessel was authorised to sail at a reduced capacity of 6,000 lane metres, down from its full 8,000 lane metres.
