Introduction to Ship Seakeeping and Manoeuvring

Understanding how a vessel responds to ocean waves and controls its direction is fundamental to safe and efficient ship design. This text-only course introduces the essential principles of marine hydrodynamics, focusing on seakeeping performance and manoeuvring characteristics. You will transition from having a basic curiosity about ships to understanding the complex physics governing ship motions in a seaway and steering control in calm water, preparing you for initial design assessments. What you'll learn: - Understand the six degrees of freedom of ship motion and how wave characteristics influence vessel behavior. - Calculate ship response in regular and irregular waves using fundamental seakeeping equations. - Analyze manoeuvring characteristics, including turning circle parameters and directional stability. - Practice evaluating rudder effectiveness and steering control derivatives. - Explore modern environmental safety criteria and basic computational methods used in contemporary ship design. The course begins with key terminology and foundational concepts of wave mechanics and rigid-body dynamics before moving into practical mathematical models for predicting ship motion and steering behavior. You will study standard manoeuvring trials and seakeeping criteria through clear, step-by-step written explanations and worked examples. This course is designed for beginners, engineering students, and maritime enthusiasts seeking a solid theoretical foundation in naval architecture, with no prior advanced hydrodynamic experience required.
