Marine Diesel Engine Oil Condition Monitoring

Source

Diesel engines power the vast majority of the global merchant marine fleet. Both two-stroke and four-stroke designs can be found in the fleet, burning fuels ranging from the heavy residual types to light distillates. The lubricating oils in these engines face many challenges, not least from varying fuel quality and diverse operating conditions. This paper reviews ASTM test methods used by ship owners and operators to monitor the condition of these in-service oils to maintain engine efficiency and optimize running costs. The shipping industry has also recognized the contribution of burning low grade diesel fuel toward climate change and is taking steps to reduce harmful emissions. For example, the International Maritime Organization introduced legislation in January 2020 to reduce the allowable sulfur content of marine fuels from 3.5% to 0.5% (by mass) outside of designated emission control areas, which have even lower limits (0.1%). This has had a significant impact on fuel quality and a consequent effect on engine operation. Routine monitoring of the condition of the lubricating oil in the engine has become even more important following this legislation and is illustrated in this review.
