“…Consequentially, diesel electric type parallel propulsion system is the most efficient option. Aims to gain from fuel consumption with this optimization technique, [26] performed the genetic algorithm (GA) method on the generators used in the diesel electric propulsion system of the diving support vessel (DSV). The operations of the DSV ship are examined in 4 different stages as transit pass, dynamic position, maneuvering and diving process.…”

Many improvements are performed in the maritime industry to ensure sustainability and energy efficiency. The use of hybrid propulsion systems (HPS) in marine vessels constitutes one of the developments in this field. In this study,both economic and environmental benefits are targeted. The study aims to reduce the high fuel consumption of the engine per unit power at low loads and minimization of emissions by sourcing them from main engine by HPS. Overcoming the limitations of Annex VI (Prevention of Air Pollution from Ships) of International Convention for the Prevention of Pollution from Ships (MARPOL) are desired and the research hopes for a beneficial result on Energy Efficiency Measures such as Energy Efficiency Operational Indicator (EEOI). A comprehensive study is accomplished on the hybrid propulsion system components and the keywords used in the literature review are revealed. Furthermore, the articles that have “efficiency”, “vessel”, “propulsion” and “marine” topics published in Web of Science (WOS) between 1975-2020 are examined and 44 studies are obtained. The studies that have been reached are analyzed and interests of them are collect under the 18 heading and the focal point of each study is highlighted in article. According to the results, the hybrid system provides low fuel consumption, minimizes emissions and costs, complies with the regulations of the International Maritime Organization, uses renewable energy sources, encourages the use of electric motors in addition to internal combustion engines, increases the efficiency of energy storage systems among other things. This article will be a significant resource for academicians, experts and companies on the Hybrid propulsion system in setting their focus. Keywords: Hybrid propulsion, Energy saving, Global warming.

“…In recent decades, diesel-electric propulsion [11,12] has grown as a good competitor for ship propulsion, bringing some additional benefits to operating flexibility and reduced footprint emission [13]. This type of propulsion system has some drawbacks due to additional energy transformations that affect the overall efficiency at maximum speed [14].…”

In recent decades, the design of ship propulsion systems has been focusing on energy efficiency and low pollutant emissions. In this framework, diesel–electric propulsion has become a standard for many ship types and has proven its worth for flexible propulsion design and management. This paper presents an approach to the optimal design of diesel–electric propulsion systems, minimising the fuel consumption while meeting the power and speed requirements. A genetic algorithm performs the optimisation, used to determine the number and type of engines installed on-board and the engines’ design speed and power, selecting within a dataset of four-stroke diesel engines. The same algorithm is then adapted and applied to determine the optimal load sharing strategy in off-design conditions, taking advantage of the high flexibility of the diesel–electric propulsion plants. In order to apply the algorithm, the propulsion layout design is formulated as an optimisation problem, translating the system requirements into a cost function and a set of linear and non-linear constraints. Eventually, the method is applied to a case study vessel: first, the optimal diesel–electric propulsion plants are determined, then the optimal off-design load sharing and working conditions are computed. AC and DC network solutions are compared and critically discussed in both design and off-design conditions.
