Common Errors and Fixes (+1)

Common Errors and Fixes

Error Cause Fix
Catenary solution diverges Horizontal tension too low for water depth and line weight Increase pretension or add more line length
Anchor capacity exceeded Environmental loads larger than holding capacity Upsize anchor or add anchor line length for catenary reduction
Safety factor < required Line MBL too low for design tensions Upsize chain/rope diameter or change material grade
Vessel offset exceeds limit Mooring stiffness too low Add more lines, shorten lines, or increase pretension
Line-line interference Mooring spread angle too narrow Increase angular spacing between lines (min 30 deg recommended)
Snap loading Slack line becomes taut under dynamic loading Increase pretension to avoid slack; add damping materials
Polyester creep Long-term elongation under sustained load Use DNV creep factors; design for post-installation elongation

Debugging Mooring Design

python
def diagnose_mooring_system(system, environment):
    """Check mooring system design for common issues."""
    issues = []

    # Check minimum number of lines
    n_lines = len(system.lines)
    if n_lines < 3:
        issues.append(f"Only {n_lines} lines — minimum 3 for station keeping")
