The invention provides a ship energy efficiency management and control platform based on fuzzy clustering and a genetic algorithm. The ship energy efficiency management and control platform comprises a sensor group, a lower computer system and an upper computer system, wherein the upper computer system comprises an upper computer communication module, a data storage module, a data processing module and a ship energy efficiency comprehensive management and control module; the data processing module is used for calling parameters in the data storage module, resolving all the received parameters and providing the resolved parameters to the ship energy efficiency comprehensive management and control module; the ship energy efficiency comprehensive management and control module is used for computing the current energy efficiency operation index of a ship in real time based on fuzzy clustering and the genetic algorithm by using the resolved parameters in order to provide references for a ship operator; through the system, optimal navigational speed, power supply form and load working state of the ship can be determined, and control commands can be output automatically. According to the ship energy efficiency management and control platform, the energy consumption state of the ship can be monitored in real time, the influences of environmental factors on the energy consumption of the ship can be eliminated or lowered, and the irrationality of the navigational speed can be set in advance, so that the aims of saving energy and reducing emission are fulfilled.
