Cylinder Oil Feed Rate – Current Low Load Advice

The main engine manufacturers acknowledge that low load ops are leading to a required change in cylinder lube oil management. It is now no longer the simple act of balancing fuel sulphur with Base Number  and feed rate. The load and relative temperature of the liner will require monitoring to ensure that conditions are avoided which can cause cold corrosion.

In addition the modern lower BN products may not be ideal in all circumstances  – I recommend a thorough review of the CLO management process when working a low load operational policy.
