Supporting dredging works for the expansion of a merchandise jetty

Morphological impact assessment and navigational and manoeuvring study

Reliance Industries Ltd (RIL) wanted to increase the material handling capacity at its Reliance Dahej Marine Terminal (RDMT). Currently, RDMT operations are restricted due to heavy siltation especially at the berthing pocket of the jetty. The existing navigational channel depth only allows smaller vessels to manoeuvre due to available draft depth limitations. Thus, the need for intensive dredging works arose in order to revamp the jetty and permit larger ships to enter and exit the area. However, the project site boasts of complex hydrodynamics. It was necessary to accurately predict the infill rate of the dredged navigational channel. With our integrated hydraulic/hydrodynamic modelling and navigation/manoeuvring studies, we supported RIL with its dredging and expansion plans.
