The FAModel (or Floating Array Model) package serves as a high-level library for modeling a floating wind array. It combines site condition information and a description of the floating array design, and contains functions for evaluating the array's behavior considering the site conditions. For example, it combines information about site soil conditions and an array's anchor characteristics to estimate the holding capacity of each anchor.
The library works in conjunction with the tools RAFT and MoorPy to model floating wind turbines and mooring systems, respectively.
In addition to the code, this repository defines a Floating Array Ontology, which provides a standardized description format for floating wind farms.
An example of use of these tools to model three mooring lines over the bathymetry of the Humboldt lease area is shown below.
To install FAModel itself, clone the FAModel repository and then enter the following in the command line from its directory.
For development use:
run python setup.py develop or pip install -e . from the command line in the main MoorPy directory.
For non-development use:
run python setup.py or pip install . from the command line in the main MoorPy directory.
The dependencies required by FAModel depend on how it is used. To install all possible required dependencies, you can create a new python virtual environment based on the included yaml listing the required dependencies.
In the terminal (Anaconda Powershell Prompt), clone this repository to a directory of your choice, navigate into the main folder of the repository, and run the following command:
conda env create -f famodel-env.yaml
This command will install all the dependencies required to run FAModel.
The library has a core Project class for organizing information and an evolving collection of subpackages for specific functions. The two current subpackges are:
- anchors: contains modules for anchor capacity calculations
- seabed: contains modules for seabed bathymetry and boundary information
- cables: contains classes that assist with power cable-related calculations
Please navigate into the subfolders above for additional information.
