Upon conducting a machinery space round on a main propulsion diesel, you detect a significant amount of water discharge when blowing down the charge air cooler or scavenging air receiver drains. What should you do?
• Engine room watchstanding responsibilities when abnormal conditions are found • Why water in charge air coolers / scavenging air receivers can be dangerous for the engine • The difference between immediate reporting of abnormal conditions and routine / non-urgent reporting
• If you find a significant amount of water where it normally should not be, how quickly could this develop into a serious problem for the main engine? • Who is the person officially responsible for responding to abnormal engine conditions during a watch or duty period? • Is this the kind of condition that can safely wait until you casually see a senior officer later, or does it affect the immediate safety and reliability of propulsion?
• Decide whether “significant” water discharge suggests an abnormal or potentially dangerous condition • Identify who is on watch or on duty and therefore responsible for taking action right now • Distinguish between routine information (can wait) and urgent safety/operational issues (must be reported at once)
