Competition is heating up among Korea's three largest shipbuilders to dominate the rapidly growing market for autonomous ships, according to industry officials, Sunday. Daewoo Shipbuilding & Marine Engineering (DSME) said last Tuesday that it succeeded in testing a DSME Autonomous Navigation-Vessel (DAN-V) near Jebu Island in Hwaseong, Gyeonggi Province, between Nov. 16 and 17. The test included remote control operation, path following and collision avoidance, according to the shipbuilder.
