Who is charged with appointing persons to be in command of the lifeboats and(or) liferafts on a mobile offshore drilling unit?

Correct Answer: Option B — Designated person in charge

46 CFR 109.213 designates the person in charge of the MODU as the authority responsible for assigning qualified personnel to command lifeboats and liferafts. This ensures that only individuals with the necessary training and competency are tasked with the safe operation of survival craft during emergency evacuation procedures.
