Changelog
[1.0.0] - 2026-01-17
Added:
- Initial release with standards compliance checking
- Mooring line capacity verification
- Safety factor calculation
- Multi-standard support (DNV, API, ISO)
When to Use
- Verify mooring line tensions against MBL limits
- Check riser stress against allowable
- Validate safety factors per design codes
- Generate compliance reports for certification
- Design verification before fabrication
- Audit existing designs against current standards

Python API
Mooring Safety Factor Check
from digitalmodel.structural.structural_analysis.capacity import CapacityChecker
def check_mooring_safety_factors(
max_tensions: dict,
mbl_values: dict,
standard: str = "API_RP_2SK"
) -> dict:
"""
Check mooring line tensions against MBL limits.
*See sub-skills for full details.*
### Riser Stress Check
```python
from digitalmodel.structural.structural_analysis.capacity import CapacityChecker
import math
def check_riser_stress(
max_tension: float,
max_bend_moment: float,
internal_pressure: float,
external_pressure: float,
od: float,
*See sub-skills for full details.*
### Standards Lookup
```python
from digitalmodel.infrastructure.common.standards_lookup import StandardsLookup
# Initialize lookup
lookup = StandardsLookup()
# Search for relevant standards
results = lookup.search("mooring design")
for standard in results:
*See sub-skills for full details.*
### Generate Compliance Report
```python
def generate_compliance_report(
check_results: dict,
output_path: str,
project_info: dict
) -> str:
"""Generate HTML compliance report."""
html_content = f"""
<!DOCTYPE html>
*See sub-skills for full details.*
