Part 1

The AI-PNA System

Part 2

Class A: Design Leads

Part 3

Class B: Engineering Disciplines

Part 4

Class C: Analysis & Calculation Tools

Part 5 & 6

Geoscience & Regulatory Review

Metocean & Geology

Class D: Site Environmental Basis

Metocean sets the environmental basis (wind, wave, current) while Environmental Geology manages seabed soils and geohazards.

Critical Input: Water Depth & Location

Regulatory Compliance

Part 6: Final Integrated Review

Always called last. It screens technical results against IMO conventions, flag law, and coastal State regimes.

Decision Support Only

7. Important Notice

AI-PNA provides technical guidance for engineering consideration. All results must be verified by qualified naval architects, marine or offshore engineers, geoscientists or metocean specialists, as appropriate.

Regulatory and classification content is preliminary guidance and is not a compliance determination, legal opinion or approval. Final designs require review and approval by the relevant classification society and authorities.
