Marine Lubricant Applications

The marine market consists of 3 segments in broad terms that use either residual or distillate fuel, which is characterized by its high sulfur content:

• Propulsion engines for large deep-draft and smaller coastal vessels
• Auxiliary engines installed on vessels
• Power generation

These applications are served by two types of engines:

• Two-cycle, slow-speed crosshead engines, which require a marine cylinder lubricant (MCL) that is injected into the cylinder during operation and a system oil that lubricates the crankcase
• Four-cycle, medium speed trunk piston engines, which require a single lubricant, commonly known as a trunk piston engine oil (TPEO), because they have a common sump for the cylinder and crankcase
