ard.offshore.mooring_design_constant_depth.generate_anchor_points(center, length, rotation_deg, N)[source]#

Generates anchor points equally spaced around the platform

Return type:

ndarray

Parameters:

  • center (np.ndarray) -- x and y of platform in km

  • length (float) -- desired horizontal anchor length in km

  • rotation_deg (float) -- rotation in deg. counter-clockwise from east

  • N (int) -- number of anchors

Returns:

array of size N by 2 containing the x and y positions of each anchor

Return type:

np.ndarray

_summary_

Return type:

tuple[ndarray]

Parameters:

  • phi_platform (np.ndarray) -- counterclockwise rotation from east in deg. for each platform

  • x_turbines (np.ndarray) -- list of platform/turbine easting in km

  • y_turbines (np.ndarray) -- list of platform/turbine northing in km

  • length (float) -- desired horizontal anchor length in km

  • N_turbines (int) -- number of wind turbines in the farm

  • N_anchors (int) -- number of anchors per turbine/platform

Returns:

x locations of anchors, y locations of anchors, each array of shape N_turbines by N_anchors

Return type:

tuple[np.ndarray]

class ard.offshore.mooring_design_constant_depth.ConstantDepthMooringDesign(**kwargs)[source]#

A class to create a constant-depth simplified mooring design for a floating offshore wind farm.

This is a class that should be used to generate a floating offshore wind farm's collective mooring system.
