🔍 Key Concepts

• Mobile Offshore Drilling Unit (MODU) specific safety-drill requirements (different from regular ships) • 46 CFR Part 109 – especially the section on drills and instructions for fire emergencies • Difference between how often fire drills are required versus abandon ship/boat drills

💭 Think About

• Think about which type of emergency (fire vs. abandon ship) typically requires the most frequent practice on any vessel or MODU. • Ask yourself: are fire hazards on a MODU constant and daily, or more tied to events like crew changes? How would that affect drill frequency? • Compare in your mind how often most maritime regulations expect fire drills on ships, then consider whether MODUs would be similar, more frequent, or less frequent.

✅ Before You Answer

• Verify in 46 CFR Part 109 the specific subsection that lists how often fire drills must be held on a MODU. • Check whether the regulation mentions a fixed time interval (like every X), or an event-based trigger (like at each crew change). • Confirm that you are not confusing the frequency for fire drills with the separate requirement for abandon ship/boat drills on MODUs.
