Course on "Hydrodynamics of moored structures"

SINTEF Ocean offers a 1-day course entitled Hydrodynamics of moored structures, targeting engineers working with hydrodynamics and/or mooring systems, with preferably more than 3 years experience.

Registration deadline

The course will be held right before the yearly TEKNA DP&Forankring av offshore installasjoner conference in Trondheim, so that it will be convenient to attend both events.

State-of-the-art on the following topics will be presented, and there will be time for questions after each presentation:

Mooring analyses

Objective: Understand the ingredients of mooring analyses, and how they are performed in SIMA

  • Goal of a mooring analysis, and quantities of interest
  • Generic design basis
  • Modelling of mooring lines
  • Low-frequency and wave-frequency loads and motions
  • Examples in SIMA
Waves, wave models, extreme waves

Objective: Understand the wave theories applied in mooring analyses, and their limitations.

  • Basics and not-so-basics about waves
  • Wave generation and propagation, at sea and in a laboratory
  • Usefulness and limitation of linear waves
  • Examples and simulation of nonlinear wave effects
Linear wave radiation/diffraction analyses

Objective: Recap the best practices when running wave radiation/diffraction analyses

  • Quantities of interest to be evaluated for a mooring analysis:
  • Basic theory of linear radiation/diffraction analysis. Retardation functions.
  • Panel models, meshing, size distribution
  • Important analysis parameters (irregular frequencies removal for ex.)
  • Experience with WAMIT and Hydrostar
Low-frequency nonlinear wave loads

Objective: Understand hydrodynamic effects that affect the low-frequency hydrodynamic loads, and how to model them in a mooring analysis.

  • Importance of low-frequency wave loads for mooring systems
  • What is a quadratic transfer function, and how to compute it?
  • Newman's approximation versus full QTFs
  • Wave-current interaction effects, and higher-order loads
  • Empirical correction of QTFs
Model testing

Objective: Understand how model tests are carried out from spec. to report, to maximize their benefits for the project.

  • Why model tests: importance of sharing clearly defined objectives with the lab.
  • How to set up a test matrix
  • How model tests are executed
  • Model manufacturing and instrumentation
  • Main error sources
CFD for offshore applications

Objective: Understand the possibilities and limitations in CFD for offshore applications, today.

  • What is CFD and when to use it
  • CFD for moored structures
  • Wind loads and current loads
  • Reproducing waves in CFD
  • Wave loads in CFD, including impact

Target number of participants will be 20-25.

The presentations will be given by senior scientists with expertise and hands-on experience in their domain.

Hard copies of the presentations will be provided for note-taking and reference.

Lunch is included.

Cost: 9000kr, excl taxes
