MAIN AND AUXILIARY ENGINES



Marine equipment presents an extremely demanding environment to tribologists. While the machine elements and the lubricants used are substantially the same as in other applications, some fundamental differences regarding the operating environment play a substantial role in their success. Important is the chemical nature of the fuels used, the operating temperatures, and the speed at which the engine runs. Although frictional losses in engines are relatively small, when it comes to large, two-stroke, marine diesel engines in ships that travel huge distances, even small reductions in friction add up. Insights into the causes of frictional losses and their reduction can be used to increase the energy efficiencies of large ships, leading to lower fuel use and, thus, lower operating costs.

Increased wear in ship main engines will cost definitely more than hoped for. E.g. if a bearing fails on a marine engine, the crankshaft might fail as well and a possible replacement of the bearing and crankshaft could be the case. The replacement will cost months and the amount of money involved will be exorbitant . At sea this eventuality will be even more catastrophic. The ship won’t be able to manoeuvre anymore, and a total loss of the vessel and its cargo might be the result. Let alone the possible loss of human life.

Therefore it is crucial to ensure that all possible has been done in order to control and monitor wear and tear in modern marine engines. Apart from the traditional ways of doing this, ENVIRO₂PRO offers a unique combination of patented characteristics in the field of tribology which assist the ship owners in controlling and reducing their operating costs and risks.

Please have a look on this website at the chapter “general explanation technology” and “Science” in order to learn more about this topic and how we think science “made in Germany” can assist you in dealing with day to day technical issues in the field of tribology.

But ENVIRO₂ offers more:

Marine fuel management is a multi-level approach to measuring, monitoring, and reporting fuel usage on a boat or ship, with the goals of reducing fuel usage, increasing operational efficiency, and improving fleet management oversight. Fuel management has grown in importance due to the rising costs of marine fuel and increased governmental pressures to reduce the pollution generated by the world's fleet.

Effective fuel management requires that you know:

   How much fuel is used
   How the fuel was used
   What things impact fuel usage
   And by how much


Manual methods of measuring fuel usage, i.e. fuel tank dipping or sounding, typically do not tell how much fuel was used:

   Traveling versus idling while in port or on station
   By a specific engine
   Performing one job versus another
   By crew A versus crew B on similar voyages


Without a clear understanding of how fuel is being used, there is no operational baseline from which to compare any kind of fuel conservation tool or activity. Without a baseline, there is no way to determine if conservation strategies are actually working.

Fuel management allows a fleet owner to track actual fuel consumption and relate fuel consumption to the work performed by the vessel. It supports the analysis of the effectiveness of operating strategies and helps develop a clearer understanding of how well a vessel uses its fuel.

Consequentially, a proper fuel management is the only way to effectively monitor a fuel consumption reduction before and after the application of ENVIRO₂PRO.
