A06 – Ship Vibration and Noise
This course aims to develop core ship vibration theory and shipboard noise assessment, from single-degree-of-freedom models, beam vibration and added mass through shaft whirl, torsional vibration and propeller excitation to sound rating, transmission paths and noise prediction at a receiver location, using worked maritime examples.

Course overview
Designed for: engineering graduates looking for refresher courses in niche expert areas.
Entry requirements: an engineering degree or equivalent experience, plus engineering dynamics (single-degree-of-freedom vibration, natural frequency and damping) and basic beam theory; familiarity with decibels helps for the noise sections.
Learning format: self-paced online lessons with audio read-out, worked vibration and noise examples (including a large container-ship drivetrain case), a laboratory-style beam frequency estimate, interactive tabs, flip cards and expandable panels, in-lesson checks, an AI tutor to answer questions as you go, and graded quizzes. This suits the aim because vibration and noise problems are solved by estimating, checking against limits and choosing a fix, so worked cases after each topic rehearse that sequence before the section quiz.
What you will learn
Set up and solve single-degree-of-freedom vibration models for ship-related mass-spring-damper systems.
Estimate the lowest natural frequency of beams and deck panels using Rayleigh’s method.
Analyze how added mass and damping from surrounding water change the vibration behavior of wetted structures.
Evaluate whirl and torsional-vibration risks in propeller-shaft systems against operating-speed excitation.
Apply decibel, frequency-band, NR-curve, and dB(A) methods to interpret shipboard noise data.
Predict shipboard noise at a receiver location using source, path, and transmission-loss reasoning.
