In the marine industry diesel engines, gear systems and hydraulics are expected to operate for long periods of time at full load capacity under extreme, often uncontrollable conditions. High performance expectations, a variety of operating environments, and the constant presence of water make marine equipment very different from equipment on land.

Analysis of lubricants, coolants, and fuels is mandatory because these units are constantly exposed to the damaging effects of fresh or salt water, which are also used by some to cool the very systems that keep them running. Fluid monitoring and control can extend equipment life and identify system problems before they turn into costly failures
