When is the work on a propulsion turbine considered complete after inspection and repair?

• A. Immediately after inspection
• B. After satisfactory dock and post repair trials
• C. After reassembly
• D. Once visual inspections are passed

Answer: (B)

The work on a propulsion turbine is considered complete after satisfactory dock and post-repair trials because these trials are critical for verifying that the repair work has been effective and that the equipment is functioning as intended. During post-repair trials, the turbine is subjected to operational conditions to ensure it performs safely and efficiently under load. This step helps confirm that all repairs were correctly executed and that there are no residual issues that could impact performance or safety. While inspections and reassembly are important steps in the repair process, they do not guarantee that the turbine will function properly in actual operating conditions. Hence, without going through the necessary dock and post-repair trials, one cannot conclusively determine the readiness of the propulsion turbine for service.
