E02 – Dredge Pumps, Hydraulic Transport & Cutting Mechanics

This course aims to build the mid-level technical understanding you need to explain what actually happens to soil and rock once cutting starts, slurry moves, and suction and pumps interact, so you can evaluate pump-pipeline operating points and equipment choices against production targets and practical cavitation, wear and efficiency constraints.

Course overview

Designed for: engineering graduates looking for refresher courses in niche expert areas.

Entry requirements: an engineering degree or equivalent experience, plus a working knowledge of how dredgers operate and a basic grounding in soil mechanics and fluid mechanics.

Learning format: self-paced online lessons with audio read-out, worked examples, an interactive scenario, a system selection case study, flip-card recall exercises, in-lesson checks, an AI tutor that guides rather than gives answers, and graded quizzes. This suits the aim because you can work at your own pace and test each idea on worked numbers before moving on.

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.
