Description of the project
Port Consultants Rotterdam conducted a dredging study for the port of Hazira. The Port of Hazira is primarily built for LNG facilities, and later expanded with a basin for a container terminal. The high current velocities of the port entrance yielded a serious design challenge. These conditions were difficult for the construction of breakwaters and dredging works either. Monsoon waves and swell affected the works further. The high silt load of the current causes large maintenance volumes in the port basin and the entrance channel. Part of the dredging study included cost estimation of capital dredging and exploring maintenance dredging strategies. Maintenance schedules combining trailing suction hopper dredgers and water injection dredgers have been tried and tested in order to minimize annual maintenance dredging costs.
