Reference Answer
### (a) Parameters to be Checked on Takeover of Watch
A thorough check of the turbocharger system during watch takeover is critical for ensuring the safe, reliable, and efficient operation of the main propulsion or auxiliary engines. The following parameters must be systematically checked and logged:
1. **Lube Oil System Parameters:**
* **Inlet Pressure:** Verify the lube oil pressure at the turbocharger inlet is within the manufacturer's specified range (e.g., 1.5 - 2.5 bar). Insufficient pressure is a critical alarm condition that can lead to immediate bearing failure.
