Ship Seakeeping Analysis Using Strip Theory Approach

This document provides a detailed explanation of calculating ship seakeeping using strip theory and implementing data processing through MATLAB programming. The first step involves defining the hull geometry parameters, including length, beam, height, and draft, which are typically stored in structured arrays or matrices within MATLAB. Next, we employ numerical computation methods to analyze wave-hull interactions, where key algorithms like finite element analysis (FEA) or boundary element methods (BEM) are implemented to simulate ship motions in seaway conditions. The MATLAB implementation typically involves solving hydrodynamic equations using matrix operations and iterative solvers, with functions like ode45 for motion equation integration.

The process requires sophisticated mathematical and engineering knowledge, particularly in implementing coordinate transformations and frequency-domain analyses through MATLAB's signal processing toolbox. Finally, data processing involves visualization techniques using plot functions and statistical analysis tools to interpret results effectively. This comprehensive approach provides valuable insights into ship-wave interactions, offering critical references for vessel design and maritime safety assessments.
