A qualified person must be assigned as the second in command of a lifeboat on a MODU if the lifeboat has a capacity of more than __________.
• Lifeboat manning requirements on Mobile Offshore Drilling Units (MODUs) under 46 CFR • Difference between person capacity of a lifeboat and the number of assigned crew • When regulations add a second in command (assistant coxswain) based on boat size/capacity
• Check in your memory or references what 46 CFR says about lifeboat crew assignments specifically for MODUs, not for regular merchant vessels. • Think about why a second in command would be needed: at what approximate number of persons does crowd control, launching, and handling require two qualified leaders instead of one? • Compare the threshold in the rule with the given answer options and match the closest higher capacity requirement.
• Verify in 46 CFR (MODU lifeboats) the exact phrase about a qualified person assigned as second in command and note the person‑capacity threshold. • Confirm that the rule is about lifeboat capacity, not the total number of persons on board the MODU. • Make sure the threshold is strictly more than the listed number ("more than X"), not "X or more," before matching it to one of the choices.
