Dredging helps to maintain the water
depth by removing sediments that
accumulates gradually.
Inflowing soil from the river becomes sediment in channel and basin in port. When it is left as, seabed level becomes shallower and port's function will be lost by hindering the vessel from navigation and mooring. We remove the sediment by dredging to secure and maintain the water depth in port. Dredging is indispensable to secure the safe navigation in port.
