MARITIME – COMMUNICATION & REGULATION CALCULATOR
Flag State Survey Interval
A precise tool.
What is the Flag State Survey Interval & How does it work?
Flag states are responsible for ensuring that vessels under their registry comply with international safety and environmental standards.
The frequency of statutory surveys varies according to vessel type (e.g., cargo, tanker, passenger) and classification society class, reflecting differing risk profiles.
A simplified calculation multiplies a base interval by factors for type and class to derive the recommended survey period.
\text{interval}=B times C_{f} times T_{f}
interval = calculated survey interval in years
