🔍 Key Concepts

• 46 CFR requirements for mobile offshore drilling units (MODUs) and logbooks • Difference between official and unofficial logbooks and when each is required • Role of the OCMI (Officer in Charge, Marine Inspection) in recordkeeping and reporting

💭 Think About

• Ask yourself: If a regulation says a unit is not required to have an official logbook, does that automatically mean no log of events is kept at all? • Consider what the Coast Guard usually wants regarding records of operations and incidents on vessels or MODUs, even when a specific official form is not mandated. • Think about which choices would most likely conflict with the general safety and inspection philosophy of the Coast Guard.

✅ Before You Answer

• Verify in 46 CFR whether MODUs have any logkeeping requirement even when an official logbook is not specified. • Check whether Form CG-706 is explicitly required for MODUs in the regulations. • Consider whether the OCMI would expect continuous records or just occasional reports of major events.
