Which of the following procedures should be carried out to permit the continued operation of a crosshead engine with a leaky aftercooler?

🔍 Key Concepts

• Function of an aftercooler in a large, low‑speed crosshead diesel engine • Effects of water or air leaks in an aftercooler on engine operation and safety • Standard temporary operating measures when critical air‑path equipment is compromised

💭 Think About

• What is the main risk to the engine if the aftercooler is leaking, and how can you reduce that risk while still keeping the engine running? • How would changing fuel type affect combustion and safety if cooling of the charge air is not reliable? • Which option best reflects a conservative, damage‑limiting operational change rather than trying to maintain full power?

✅ Before You Answer

• Identify which choices involve operating at reduced speed/power versus maintaining normal sea speed. • Consider which procedure directly addresses the leak problem rather than ignoring it. • Ask whether shutting off or bypassing a cooling component could cause overheating of charge air, and how that would affect safe engine loading.

Which of the following procedures should be carried out to permit the continued operation of a crosshead engine with a leaky aftercooler?

Nothing needs to be done due to the low heating value of heavy fuel.

Switch to diesel fuel and run at reduced speed.

Blank off the cooling water lines and run at reduced speed.

Bypass the aftercooler to operate at sea speed.
