Stern Tube Oil Testing

Ensuring optimum stern tube lubrication performance and reliability

Stern Tube Oil Testing

Stern Tube Lubricating Oil systems operate under difficult and severe operating conditions, these Oils are exposed to seawater which can cause rust and corrosion, wear and tear due to heavy operating conditions of the propellor shaft which could lead to the formation of wear metals and oxidation of the Stern Tube Lubricating Oil due to heavy use. The IACS (International Association of Classification Societies) mandates that testing of the Stern Tube Lubricating Oil should be ideally carried out every 6 months, but it is noticed that ship owners and managers prefer testing the oil every 3 months for optimum performance.  

Atlas Lab provides a comprehensive state-of-the-art Stern Tube Lubricating Oil testing and analysis service. We test the Stern Tube oils as per the following world-class standards such as ASTM - American Society for Testing and Materials, ISO - International Organization for Standardization etc. The various tests conducted for Stern Tube Oil are Density, Kinematic Viscosity, Flash Point, Pour Point, Water, Carbon Residue, Ash, Sulfur etc. Tests for Stern Tube Oil are carried out by experts in the field of testing and analysis with over 40 years of cumulative experience to provide exact results for your Stern Tube Oil-related issues. Atlas lab offers a complete solution for Stern Tube Oil with quick and precise test results at a cost-effective price to clients on a global scale.
