Wave Data and Load Analysis


Based on on wave data analysis, the primary purpose is to document wave loads based on concise descriptions with mathematical background.

Wave data analysis involves application of accepted time-series analysis and spectral analysis techniques, and includes the mathematical background and theory which applies to analysis of load from wave analysis. The calculation procedures needed to establish the structural loading generally involve the following steps in which knowledge of the surface waves is essential: 

  1. establishing the wave climate in the vicinity of the structure,
  2. estimating design wave conditions for the structure, and
  3. selecting and applying a wave theory to determine the hydrodynamic loading on the structure.

As the fundamental properties of surface waves, induced by wind, is their irregularity, the prediction of wave parameters can be achieved only through stochastic analysis of the sea surface, which span three basic domains: time, frequency, and probability.

The wave data analysis procedure involved finding the significant wave height along with the significant wave period, assigning a Sea State value, and detailed spectral and statistical description of the wave data.

A complete physical and statistical description of the proposed operating environment is a vital component of the design process. Natural frequencies, relative geometries and scale, and other static and dynamic response characteristics are largely defined by the significant wave height and period of the seas, the direction/interaction of the sea, swell condition, and other data.

Application Programming Interface - API

Some software packages can be driven via an application programming interface (API), as well as being used as a normal Windows program. An API is a connection between computer programs, or a type of software interface, offering a service to other pieces of software. This application is such a software that uses an API to support in the aero- and hydrodynamic modelling and analysis.

A methodology for hydrodynamic modeling in offshore renewables is outlined using integration with a hydrodynamic solver. The application programming interface (API) is used to integrate applications in order to perform a task to share data and to execute pre-defined processes. For example, hydrodynamic simulation requires some preparation to be done before it can be numerically set up and performed. This step is called pre-processing input data, in order to idealize a physical design and create a model for analysis.

The API enables idealization of a model based on geometric and environmental information and then simulate how that model will behave under certain real-life conditions.

This Figure is showing the three stages linked together by file.


Following hydrodynamic simulation, a post-processor is used to analyze and present the simulation results and customize the representation. The postprocessor imports and displays the results and helps the understanding of model behavior. It has the ability to perform some analysis work on the output, for example extreme load analysis and statistics. An editor provides the environments and the tools to create reports, including model visualization and charts.
