LUBESAFE COLD CORROSION MONITORING CYLINDER SCRAPE DOWN OIL TEST

COLD CORROSION MONITORING SOLUTION for MARINE MAIN ENGINE

Lately, in order to improve fuel oil consumption and reduce emissions, new sailing and operating practices have emerged such as ‘slow steaming’ or ‘super slow’steaming, especially at engine low load. There are different modes of slow steaming: reduced speed, moderate slow steaming, deep slow steaming and ultra-slow steaming.

Proven benefits include higher fuel savings and significant reduction in carbon emissions (CO2, NOX and SOX .Main marine engine manufacturers (OEM) have consistently supported and endorsed ship operators running their fleet under slow steaming modes. However, most ships operating at slow steaming are equipped with engines which have not been fully designed for running at low loads or under slow steaming conditions. Marine modern engines designs which include long strokes and super long strokes features fall under that category.

Hence high combustion chamber pressure and liner cooling intensity, together with the increased operating time at low load (slow steaming) generate “cold corrosion” on the cylinder liners which is actually a corrosive wear caused by acid condensation resulting from a drop in engine operation temperature during the slow steaming mode or when the overall length of the stroke is increased due to engine design.

Cylinder Scrape-Down Oil Analysis (CSDOA)

Unimarine Cylinder Scrape-Down Oil Analysis (CSDOA) is a laboratory-based special analysis service that monitors parameters of piston underside oil. CSDOA is not only able to identify cold corrosion of cylinder liners and provides early warning for the chief engineer but also contributes to the optimization of cylinder oil feed rate and hence contributes as well to costs control.

CSDOA monitors following oil parameters:

  • Metal Content
  • PQ Index
  • Element Content
  • BN Value
  • Additive Level
  • Viscosity
  • Viscosity Index
  • Flashpoint
  • Water Content
