## Splash Zone Analysis Checklist


- [ ] Wave Hs appropriate for installation weather window (typically Hs < 2.5m)
- [ ] Fine depth increments through splash zone (1-2m steps)
- [ ] Hydrodynamic coefficients set for partially submerged structure
- [ ] Slamming loads considered (if applicable)
- [ ] Crane wire dynamic amplification factor applied
- [ ] Structure orientation at each depth is physical

## Validation


| Check | Method | Acceptable Range |
|-------|--------|-----------------|
| Crane wire tension | Extract from static results | < crane SWL with safety factor (typically SF > 2.0) |
| Structure elevation | Compare 6DBuoy Z with target | Within 0.1m of target delta_elevation |
| Wire length | Sum of wire sections | Reference length + abs(delta_elevation) +/- 1% |
| Sling tensions | Extract from static results | Positive (no compression in slings) |
| Static convergence | model.CalculateStatics() | Converges at all depths |
| Touchdown | Check structure Z vs seabed | Structure Z > -water_depth (not through seabed) |
