🔍 Key Concepts

• Lifesaving appliances requirements for offshore drilling units in 46 CFR • The purpose of ring buoys with self-activating water lights • Which type of additional distress signal is commonly paired with a MOB (man overboard) lifebuoy

💭 Think About

• Think about what extra signal would help rescuers locate a person in the water at night or in low visibility in addition to the light. • Consider which choice is most commonly paired with lifebuoys on SOLAS and U.S. vessels as a visual distress and location aid. • Ask yourself which option is a simple, passive device that does not require complex electronics or crew action once the buoy is released.

✅ Before You Answer

• Check 46 CFR requirements for ring life buoys and water lights on MODUs/offshore units. • Verify which device is normally combined with the lifebuoy light to mark a man overboard position. • Eliminate options that would require power, wiring, or radio equipment on the buoy itself, and focus on standard, rugged lifesaving gear.
