🔍 Key Concepts

• 46 CFR regulations on Certificates of Inspection (COI) for offshore drilling units (MODUs) • Purpose and nature of a temporary certificate versus a permanent one • Which agency or document actually issues/controls a Certificate of Inspection under U.S. law

💭 Think About

• Ask yourself: who is legally responsible for issuing and controlling a Certificate of Inspection on a U.S.-inspected unit? Is it a federal agency, a classification society, or a document like an operations manual? • Think about what a temporary certificate is meant to bridge between: what condition exists now, and what condition will exist once all normal inspection and paperwork are complete? • Consider which of the options is directly connected to the COI itself, rather than being an external approval that might happen on a different timeline.

✅ Before You Answer

• Verify which entity in 46 CFR is identified as issuing the Certificate of Inspection for inspected vessels and offshore units. • Check whether a temporary COI is described as remaining valid until a specific document is issued, or until some separate agency’s approval occurs. • Confirm that a classification society and an operations manual are not the same thing as a U.S. Certificate of Inspection and do not replace it.
