“…While carrying out further work on electric and hybrid propulsion [19][20][21][22] on the occasion of a small inland shuttle ferry project for the city of Gdańsk (Figure 1), the designers paid particular attention to the problem of energy management [23][24][25][26]. It turned out that the classic methods of calculating the demand for propulsion power [27,28] are practically useless.…”

Interest in hybrid propulsion systems that can be used on small vessels has increased significantly in recent years. They can replace inefficient and environmentally burdensome conventional systems based on diesel engines. Hybrid propulsion has many advantages such as high energy efficiency and virtually noiseless operation, and therefore it fits well with the current trends of “green shipping” and “zero emission”. The aim of the research conducted was to examine and analyse the varied energy demand of a small inland ferry with electric propulsion depending on the navigation strategy. The work included tests carried out on a model of the vessel. Conventional resistance tests involving towing the model at a constant speed proved to be of no use for the unit, which, during a short voyage, moves with variable speeds and manoeuvres. Therefore, atypical and unique tests were performed to determine the energy consumption during the acceleration of the unit and the parameters of navigation with the propulsion turned off. The work resulted in calculated forecasts of energy consumption by the ship depending on the adopted cruising style and a proposal of the most energy-efficient way to cross the shipping route connecting the two banks of the Motława River in the city of Gdańsk.

“…В судоходной отрасли при росте стоимости энергоресурсов и отрицательного воздействия морского флота на состояние окружающей среды проблема энергоэффективности приобретает важное значение. При этом судостроительная промышленность все больше сосредотачивается на концепциях электроэнергетических систем, улучшающих электромагнитную совместимость установленных потребителей, так как разные производители выдвигают определенные требования к качеству электрической энергии, потребляемой их продукцией [1].…”

At present, with the rise in the cost of energy resources and the negative impact of the marine fleet on the environment, the problem of energy efficiency in the shipping industry is becoming important. Most of the technical processes carried out on a ship board are somehow associated with the consumption of electrical energy, which, in turn, leads to stricter requirements for the quality of electrical energy. This is explained by the fact that the various consumers of electrical energy are designed to operate at certain values of electrical parameters such as rated current, rated voltage, rated frequency of the electrical network. In this case, it is necessary to take into account the fact that, due to the inhomogeneity of current-voltage characteristics, a large number of consumers can adversely affect the symmetry of voltage and current. This phenomenon can be partially reduced by introducing electrical energy converters to power consumers, including electric motors, which also allows the speed to be controlled in a wide range. However, commutations occurring in conversion technology will be a source of higher harmonics. In order to minimize the influence of semiconductor converters of electrical energy on the network, manufacturers can implement the following technical solutions: increasing the number of voltage ripples in the input rectifier; installation of a network choke; the use of an active harmonic filter; the use of smoothing filters in the DC link. The ways to improve the quality of electrical energy by introducing higher harmonic filters are discussed in the paper. Equations are written to determine the parameters of the elements included in the filters. A computer model of the considered electric power plant in the environment of dynamic modeling of technical systems SimInTech has been compiled. The graphs of voltage and current changes at activeinductive load are taken.

“…It transpires that in regions covered by speed limits, when the propulsion operates on a fraction of its nominal power, the energy efficiency of the internal combustion engine significantly decreases. Therefore, for at least several previously described reasons, it is beneficial to install a hybrid propulsion system on the vessel [20][21][22]. Then, in the areas covered by speed limits (when the power demand is lower), the optimal solution is to use electric propulsion.…”

The growing requirements for limiting the negative impact of all modes of transport on the natural environment mean that clean technologies are becoming more and more important. The global trend of e-mobility also applies to sea and inland water transport. This article presents the results of experimental tests carried out on a life-size, parallel diesel-electric hybrid propulsion system. The efficiency of the propulsion system was analysed for two modes of operation (electric and diesel) and for different engine speeds and loads. Analysis of the impact of using a hybrid propulsion system on fuel consumption was carried out on a case study vessel and for six actual journeys. The use of hybrid propulsion in "zero emission" mode enables up to four times higher energy efficiency when compared to a conventional drive, while reducing CO 2 emissions and air pollution to zero, as well as a hundred-fold reduction in noise emissions. High flexibility in the operation of such a drive enables the use of intelligent power control technology (smart propulsion). This article shows that the use of hybrid propulsion reduces the negative impact on the environment to a minimum and allows for a significant reduction in the vessel's operating costs.
