Abstract

In this paper are presented results of the analysis related to two identical, parallel operating MAN B&W 6S70ME-C diesel engines and their cylinders at three low loads. Analyzed main engines are used for the commercial LNG carrier drive. The range of produced effective mechanical power in each cylinder is between 624.6 kW and 1638.1 kW, while the range of cylinder mechanical efficiency is between 86.56 % and 92.87 %, considering all the cylinders of both main engines at all three observed loads. Deviations from the whole engine mean indicated pressure and the whole engine mean maximum pressure (deviation limits are defined by the engine maker) are the best parameters for detecting possibly problematic cylinders and cylinders to which high attention should be placed. At each observed engine load, the PORT main engine develops higher mechanical power, has higher efficiencies and lower specific effective fuel oil consumption in comparison to the STARBOARD main engine. Both main engines should avoid extensive operation at low loads and their operation should be maintained at Continuous Service Rating (CSR) or Maximum Continuous Rating (MCR) as long as possible, with an aim to achieve the highest efficiencies and the lowest specific effective fuel oil consumption.
