Port of Belawan, Berth Scour Protection

Concrete Mattress

The port was expanded in the early 1980’s by using a fine sand hydraulic fill. Piled jetty structures were used with a range of ground improvement methods to limit fill settlement. Revetment slopes were protected by a porous Filter Point mattress FP150 with an average thickness of 100mm with a geotextile under layer. The protection was to resist bow thrusters action, manoeuvring propeller wash, wave action to 0.5m and tidal currents to 1m/s.
