Design Check Matrix (+2)
Design Check Matrix
| Check | Intact (DNV) | Damaged (DNV) | Method |
|---|---|---|---|
| Line tension SF | >= 1.67 (dynamic) | >= 1.25 (dynamic) | Max tension / MBL |
| Vessel offset | < 8% water depth | < 12% water depth | Max offset in design storm |
| Anchor capacity | SF >= 1.5 | SF >= 1.2 | Max anchor load / holding capacity |
| Line fatigue | Design life x3 | — | Miner's sum across sea states |
| Collision check | No line-line contact | — | Minimum separation > 2 * line diameter |
Validation Code
def validate_mooring_design(results, safety_factors):
"""Validate mooring analysis results against design criteria."""
checks = []
all_pass = True
for result in results:
# Tension safety factor
sf = result.safety_factor
sf_req = safety_factors.get(result.load_case, 1.67)
