Question 1 of 27070

Each emergency generator on a mobile offshore drilling unit, when tested, must be run under a full load for at least __________.

🔍 Key Concepts

• 46 CFR requirements for mobile offshore drilling units (MODUs), specifically the section on emergency generators • The purpose of full-load testing of emergency generators and how long is needed to prove reliability • Difference between routine start tests and duration-load tests for emergency power systems

💭 Think About

• Think about why the Coast Guard would require a minimum full-load run time: what failures or weaknesses are they trying to uncover? • Consider which answer choices are more typical of a test duration versus a continuous operating requirement. • Ask yourself: for a MODU, how long does an emergency generator need to carry full load to reasonably demonstrate reliability without causing unnecessary wear or taking too long?

✅ Before You Answer

• Verify in 46 CFR Part 109 (or the current MODU regulations) the specific testing requirements for emergency generators. • Check whether the regulation talks about "tested" versus "capable of operating"—these are different requirements and have different time periods. • Eliminate options that are clearly too short to demonstrate reliability or unrealistically long for a test run rather than actual emergency endurance.
