🔍 Key Concepts

• Industrial personnel definition for Mobile Offshore Drilling Units (MODUs) in 46 CFR Part 109 or related MODU regulations • Which persons are normally classified as crew versus industrial personnel on a MODU • Who must be listed on or required by the Certificate of Inspection (COI)

💭 Think About

• Look at how the regulations separate people into categories: crew, industrial personnel, and special positions. Which of the listed choices clearly belongs to a different category than general industrial workers? • Ask yourself: who is essential for safe operation of the MODU and therefore usually treated as part of the vessel’s required complement rather than ‘industrial personnel’? • Think about which role is directly tied to regulatory responsibility and command of the unit, rather than to performing the industrial work itself.

✅ Before You Answer

• Verify in the MODU regulations how industrial personnel are defined and which categories of persons are excluded • Check whether personnel required by the Certificate of Inspection (COI) are usually counted as crew or as industrial personnel • Confirm which of the listed positions has overall responsibility or designated authority for safety and operation, and whether such a person would normally be grouped with industrial workers
