DREDGING MARINE MUD AT DUMAI PORT

Workers operate heavy equipment to dredge marine mud and garbage around Dermaga C port Pelindo I Dumai in Dumai, Riau, Sunday (7/6/2020). Dredging around the Dumai Port which is not far from the river muara is done periodically to increase the depth of the sea so that the pier can serve large-toned ships that will lean.
