E02 – Dredge Pumps, Hydraulic Transport & Cutting Mechanics

This course develops the mid-level technical foundations of dredging mechanics: how soil and rock are cut, how slurry is pumped and transported, and how pump-pipeline systems are selected and operated in practice. It bridges basic dredger familiarity and advanced equipment design by focusing on the physical processes inside dredging operations.

Course overview

This course develops the mid-level technical foundations of dredging mechanics: how soil and rock are cut, how slurry is pumped and transported, and how pump-pipeline systems are selected and operated in practice. It bridges basic dredger familiarity and advanced equipment design by focusing on the physical processes inside dredging operations.

What you will learn

Explain how pore pressure, dilatancy and cavitation influence soil and rock cutting resistance.

Distinguish major cutting and failure mechanisms and relate them to material type, geometry and operating conditions.

Describe the breaching process and predict how suction-mouth movement affects sand production.

Explain how centrifugal pump theory leads to real dredge-pump characteristics and operating constraints.

Compare slurry transport models and interpret deposition-limit velocity, concentration measures and settling behaviour.

Evaluate pump-pipeline operating conditions against production, cavitation and practical equipment criteria.
