Properties and Specifications of LSHFO, MDO, and HFO used for Main Engine, and Auxiliary Engine

Read
about fuel Oil Specifications like LSHFO, MDO, and HFO for Main Engine, and Auxiliary
Engine Used on Ship. These are particular for a ship and are intended only to
give certain ideas about fuel oil quality. Some other ships might have different
value for it, but the properties and features which are used for evaluation
will remain the same.
