🔍 Key Concepts

• Typical functions of an automated gas turbine control system on marine installations • Difference between operational control vs. safety protection vs. monitoring/indication • What types of control (pneumatic, hydraulic, electric/electronic) are usually about how things are actuated rather than what the system is designed to do

💭 Think About

• Think about what a shipboard gas turbine control system must ALWAYS do to protect the machinery and the ship, even if an operator makes a mistake. • Separate in your mind the method of control (how signals move: air, oil, electricity) from the purpose of the control (what the system actually accomplishes). • Ask which answer choice lists three broad, high‑level functions rather than specific technologies or one very special function.

✅ Before You Answer

• Identify which options describe basic system purposes (what it does) versus types of actuators or signal media (how it does it). • Ask: does the control system need a specific safety/protection role? If so, which choice clearly includes it? • Confirm which set of three functions would be found together in an automatic control and protection description in a gas turbine manual.

In a gas turbine propulsion installation, the typical control system is designed to perform which of the following three functions?

Operational control, safety control, and monitoring

Pneumatic control, electric control and monitoring

Pneumatic, hydraulic, and electric control

Operational control, speed control, and braking
