What is the minimum required number of ring life buoys on a MODU?

🔍 Key Concepts

• MODU (Mobile Offshore Drilling Unit) lifesaving appliance requirements in 46 CFR and/or IMO MODU Code/SOLAS • The relationship between number of persons on board and required lifebuoys (ring life buoys) • Distinction between ships and offshore units: MODUs often have more lifesaving gear than a small vessel of similar size

💭 Think About

• Think about why a MODU might need more lifebuoys than a small cargo vessel of similar length. How many different locations around the perimeter need quick access to a lifebuoy? • Consider whether the regulation sets a fixed minimum number for MODUs, or if it scales with length or number of persons on board. • Visualize a typical offshore rig: would just a few lifebuoys cover all working areas and boat landings, or would many be spaced around the unit?

✅ Before You Answer

• Check 46 CFR Part 108 (Design and Equipment for MODUs) or the IMO MODU Code section on lifesaving appliances for a specific minimum number of lifebuoys. • Verify whether the regulation lists a table of minimum lifebuoys for MODUs (not general cargo or passenger ships). • Confirm that the answer choice you pick reflects a number appropriate for a large, multi-deck offshore unit with multiple work areas exposed to the sea.
