Slow streaming is a process of deliberately reducing the speed of cargo ships to cut down fuel consumption and carbon emissions.  The major benefits of slow steaming have been:  Higher fuel savings  Reduction in carbon emissions (CO2, NOx and Sox)  Improved reliability  Increased efficiency Slow steaming and ultra slow steaming has helped many ship owners and companies during high bunker cost period and financial recession. But running engines on slow or reduced MCR brings many disadvantages to the smooth operation of engines which are designed for optimum running. Manufacturers always suggest to run the engines on their optimum MCR. Marine engineers have following concerns regarding the slow steaming of the engines: 1) Increased scavenge and under piston inspection 2) Over lubrication 3) Carbon deposits on the fuel valves decreasing their efficiency 4) Fouling of turbochargers 5) Frequent fouling of exhaust gas economisers 6) Turbochargers running outside their desi...
