Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

Home Courses Offshore Hydromechanics Part 2

Overview

Part 2 of offshore hydromechanics (OE4630) involves the linear theory of calculating 1st order motions of floating structures in waves and all relevant subjects such as the concept of RAOs, response spectra and downtime/workability analysis.

Course Objectives:
Participants who have successfully completed the course will be able to carry out computations at a superior knowledge level involving computations relevant for first order forces on and resulting motions of floating structures.

What you will learn

  • Definitions of ship motions in 6 DOF
  • RAO’s and phase angles of harmonic properties (motions, forces, wave elevations, etc)
  • General motion equation: how to determine all the terms in the equation, how to solve the equation in order to obtain RAOs/phase angles
  • Potential flow due to undisturbed wave
  • Numerical potential flow due to wave radiation and diffraction
  • Combine motion RAOs and derive RAOs of related properties
  • Calculate probability of exceedance
  • Carry out downtime/workability analysis
