| Abstract:In view of the characteristics of tugs, including complex operating condition, small hull structure, compact space and low speed operation at the port, from the environmental protection and energy saving point of view, different design programs of the propulsion power system are put forward. With the use of self-developed multi-program evaluation software based on the AHP algorithm, the different design programs were evaluated, and the appropriate propulsion power system design was determined. In this design, the diesel-electric hybrid system is arranged on the high-speed propulsion shaft by the reversible shaft motor, so that the tug could realize economic operation under various operating modes. Compared with the main diesel engines of traditional tugs, the installed power is reduced by about 20%. The comprehensive energy efficiency increases significantly. |
