More than 500 bulkers have been hit by congestion at Asian ports, data from Thomson Reuters Eikon shows.
Delays have tied up between 400 and 500 large ships across China, while another 100 are waiting to load coal on Indonesia's Kalimantan Island, most of them at Samarinda and Taboneo, the company said.
The congestion started in late 2017, when 300 ships were reported delayed off China and Australia.
