7.1 Local and international regulations
Verify compliance with:
- Maritime legislation
- Environmental permits
- Border agreements
7.2 Geopolitical risks
Factors like:
- Diplomatic tensions
- Technological restrictions
- Trade sanctions
may limit the operation or supply of components.
7.3 Nationality and security policies
Some countries prefer national suppliers or strategic allies for data security reasons.
8. Sustainability and environmental responsibility factors
