Abstract
This research presents a numerical and regressional analysis of a self-propelled trailing suction hopper dredger capability in the Chanomi creek of 4m depth. The analysis considered using relation that expresses the payload, lightweight, deadweight, hopper capacity, work schedule, pump capacity, engine performance, and sand density to determine the possible operation and duration of the excavation project based on the vessel cycle time. Using the regressional relationship, the dredger capacity was obtained, and the result shows that a propulsive power of 678.75kW, bow thrusters power of 116.9kW, and pump power of 540kW is needed for a 2324 tonnes hopper dredger capacity for the project. The result further revealed that the pump flow rate of 0.45m3 /s per suction tube with a suction diameter of 0.338m is needed to fill the hopper capacity of 1000m3 every 60 minutes. For a payload of 1356tonnes, the reclamation operation requires 466trips for one year. This provides an operational guide to operators in the sector on decision making and cost reduction operation.
