🔍 Key Concepts

• Chain of command on a MODU (Mobile Offshore Drilling Unit) • Who the Coast Guard and regulations recognize as the official person in overall charge of the unit • Difference between company/operations roles vs. legally designated command roles for emergency equipment such as lifeboats and liferafts

💭 Think About

• Think about which of these job titles is formally recognized in regulations as having overall authority on the MODU, especially for safety assignments. • Ask yourself: during an abandon-unit drill, whose orders are followed for manning and launching survival craft? • Which position is explicitly named in regulations and safety management documents as responsible for assigning lifeboat/liferaft commanders?

✅ Before You Answer

• Verify which position is the master-equivalent or overall person in charge of the MODU under regulations. • Distinguish between operational/technical roles (drilling/production) and command/safety roles. • Confirm which job title would appear in regulatory language or the Safety Management System as responsible for emergency organization and assignments.
