🔍 Key Concepts

• SOLAS (Safety of Life at Sea) requirements for emergency power and emergency generators • Specific testing and maintenance intervals for emergency equipment on mobile offshore drilling units (MODUs) • Why emergency power must be reliable and how frequent testing supports that

💭 Think About

• Think about how critical an emergency generator is on a MODU and how quickly conditions can change offshore—would that call for very frequent, moderate, or infrequent testing? • Compare the answer choices to typical inspection and maintenance cycles: which options sound more like routine checks, and which sound more like long-term inspections? • Consider what interval would balance safety (early detection of problems) with practicality (not overburdening the crew).

✅ Before You Answer

• Verify what interval is specifically required for emergency generator testing on mobile offshore drilling units in the applicable regulations (not just ships in general). • Confirm that you are thinking about a test/run of the generator itself, not a full blackout or load test unless the regulation specifies that. • Double-check whether there is a distinction between visual checks and operational tests, and which one the question is asking about.
