Modern marine Diesel prime movers are equipped with so called ‘common rail’ as a part installed in the fuel injection system. This kind of design, gives a possibility to control fuel injection process in ways which were not available to carry out on conventionally designed engines. During the ship operation with a reduced speed and reduced load of the main engine, especially under the “Super Slow Steaming” conditions the waste heat recovery process in exhaust gas boiler is being disturbed. In the article, there is presented a possibility to increase the steam production of the waste heat boiler by interference in the fuel injection pattern for the engine. For the selected system “low speed main engine – smoke tube exhaust gas boiler” the test session has been carried out under the real ambient and operational condition of the ship to verify described possibility. Obtained results have been presented.
