Optimisation of the depth of the navigation channel of the Musi river

In this report a prediction has been made for the influence of water depth in the Musi river on the shipping costs for vessels that call the harbour of Palembang. To this day shallow parts remain in the navigation channel. Due to these shallow parts vessels often have to postpone their entry of the Musi river until the tide provides enough depth. The vessels which call Palembang harbour have relatively low payloads, because they reduce the payload in order to have lower waiting times. A larger depth can also lead to a higher payload. From 11.3 the conclusions can be drawn that an increase of water depth will lead to shorter waiting times on the Musi river and possibly to an increase in payload, thus making less calls necessary. From chapter 12 the conclusions can be drawn that the optimum water depth for the Musi river is around LWS -6.5 m. For this depth the line for the fleet with 30% draught increase is favourable (Figure 49). This means that the optimum cost reduction can be attained for a draught increase in the order of 30% where possible. The reduction for the shipping costs is in the order of 30 billion Rupiah per year.Hydraulic EngineeringCivil Engineering and Geoscience
