Cermet-Coated Piston Rings for Operation on Low-Sulphur Fuels

For owners and operators of MAN B&W two-stroke marine diesel engines (Type: MC/MC-C, ME/ME-C, ME-B.) Cermet-coating on the piston ring running surface increases the reliability of the main engine. In many cases, the cermet-coated rings continue to perform after an episode with momentary oil film breakdown, provided the oil film is restored. This ensures that the engine can continue in normal operation until the next planned overhaul. We recommend that introduction of this new ring configuration is done at the next overhaul of an engine.
