Alternative fuels and fuel-flexible ships are often seen as promising solutions for achieving significant greenhouse gas reductions in shipping. We formulate the selection of alternative corresponding ship power systems a bi-objective integer optimization problem. apply our model to Supramax Dry-bulker solve it lower bound price scenario including carbon tax. Within this setting, question wheth...

In view of fault diagnosis of the ship generator , the paper proposes improved fault diagnosis method of ship generator ,which is Optimized Neural Network based on Multipopulation Chaos Genetic Algorithm. The results prove that the method effectively solves low precision,slow constringency and local minimum of neural network and improves global search ability, optimizes the rate and precision o...

In order to realize the comprehensive utilization of multiple energy sources in renewable ships and improve rate system economy, this paper studies matching optimization power generation ship system. Firstly, structure is introduced. Considering natural conditions actual situation for first time, wind generation, photovoltaic storage devices are configured The objective function including annua...

In recent years a great deal of research efforts in ship hydromechanics have been devoted to practical navigation problems in moving larger ships safely into existing harbours and inland waterways and to ease congestion in existing shipping routes. The starting point of any navigational or design analysis lies in the accurate determination of the hydrodynamic forces generated on the ship hull m...

Coarse and accurate power accounting methods for ship electric propulsion are observed and compared. For the purpose of analysis, the propulsion system has been separated into two units, namely the ship load and the motor drive. In the load model, variation of such factors like static and dynamic hull resistance and efficiency is explored while the supply characteristics, drive loading, propell...
