🔍 Key Concepts

• Industrial personnel vs. crew/passengers on offshore drilling units • What information is legally required to appear on a U.S. Coast Guard Certificate of Inspection (COI) • Which documents are primarily class/safety certificates vs. regulatory manning/limitations documents

💭 Think About

• Which of these documents is issued by the flag state (U.S. Coast Guard) and sets legal limits on people allowed to be carried? • Which certificates are mainly about construction standards or international safety compliance, rather than day‑to‑day operating limits? • When the Coast Guard inspects an offshore unit, where would they write the maximum number of industrial personnel allowed on board?

✅ Before You Answer

• Verify which document lists maximum number of persons carried and their categories (crew, offshore workers, industrial personnel, etc.) • Check which option is specifically a U.S. national regulatory document, not an international SOLAS certificate or a private owner’s manual • Confirm which document inspectors physically review and endorse when authorizing operational limits for the drilling unit
