The 90-day retention requirement for DOS is counted from the end of its what?

• A. Effective period
• B. Calendar year
• C. Voyage
• D. Port stay

Answer: (A)

The timing hinges on the document’s validity window. The 90-day retention for a Declaration of Security starts at the end of its effective period, not from a calendar date, a voyage, or a port stay. This ensures that inspectors can review the entire period the DoS covered, even after its validity has expired, by keeping the record for a fixed post-expiry window. A calendar year wouldn’t fit because the DoS’s validity can begin and end at any date; tying retention to a voyage or port stay wouldn’t reflect the document’s overall security period.
