🔍 Key Concepts

• Lifeboat readiness requirements on offshore drilling units (MODUs) • Difference between inspection, drill, and operation of machinery requirements • How frequently critical propulsion equipment must be run to stay reliable

💭 Think About

• Think about how often you would need to actually run a small diesel lifeboat engine so that it will reliably start in an emergency. • Is this requirement more like a daily check, a routine weekly exercise, a broader monthly test, or a long‑interval annual evaluation? • Compare this to other emergency equipment on MODUs—are propulsion systems usually checked more or less frequently than visual inspections?

✅ Before You Answer

• Verify what 46 CFR says specifically about lifeboat engines on mobile offshore drilling units (MODUs), not ships in general. • Check that you are not confusing the frequency for abandon‑ship drills or launching the lifeboat with the frequency for just operating the lifeboat motor ahead and astern. • Confirm whether the regulation uses the word "at least" with the time interval you are choosing, indicating a minimum required frequency.
