B06 – Resistance & Propulsion
This course aims to show how naval architects estimate ship resistance, convert resistance into power requirements and relate installed power to propeller-generated thrust, moving from drive-train power definitions through resistance analysis and model testing to core screw-propeller concepts.

Course overview
Designed for: engineering graduates looking for refresher courses in niche expert areas.
Entry requirements: an engineering degree or equivalent experience, plus basic engineering mechanics and fluid mechanics (pressure, velocity, Reynolds number).
Learning format: self-paced online lessons with audio read-out, worked examples (drive train, EHP to SHP, model-to-ship scaling), interactive tabs and flip cards, in-lesson checks, an AI tutor to answer questions as you go, and graded quizzes. This suits the aim because each power definition is used straight away in a worked example, which suits a foundation course building toward powering calculations.
What you will learn
Explain how power is transmitted from a ship’s prime mover to the propeller and distinguish BHP, SHP, DHP, THP, and EHP.
Calculate delivered or installed power from stated efficiencies and operating requirements.
Interpret the main components of hull resistance and how they change with speed, flow regime, and operating conditions.
Apply similarity principles and Froude scaling to relate towing-tank model results to full-scale EHP predictions.
Explain how screw-propeller geometry and operating phenomena influence thrust and propulsion performance.
