🔍 Key Concepts

• Reversing turbine purpose in a marine steam turbine plant • Difference between normal operations and emergency-only operations • How a ship uses astern power for backing, stopping, and maneuvering

💭 Think About

• Ask yourself: Is the reversing turbine designed only for rare emergencies, or is it a regular part of astern operation? • Think about all the situations when you need power in the astern direction: which of the listed options require astern power? • Consider how a steam turbine ship would handle close‑quarters handling in port—what role would the reversing turbine play?

✅ Before You Answer

• Verify whether the reversing turbine is solely for emergency use or also for routine astern movement. • Check if backing and maneuvering in tight spaces typically require astern power from the turbine. • Confirm whether an emergency stop on a turbine ship is normally achieved by applying full astern power with the reversing turbine.
