Basic Design

# Define line segments
chain = MooringLineProperties(

    holding_capacity=5000.0,
    location=(400.0, 0.0, -100.0)

# Create mooring line

    segments=[chain],
    anchor=anchor,
    fairlead_location=(20.0, 0.0, -10.0),

# Create system

# Analyze
designer = MooringDesigner(system)
results = designer.analyze_intact_condition(

Generate OrcaFlex Model

from mooring_design import OrcaFlexModelGenerator

generator = OrcaFlexModelGenerator(system)
generator.generate_model_yml('models/mooring_analysis.yml')
