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
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")
