“…A study conducted by [21] stated that the EEDI formula will differ for ships operated in inland water and open seas thus new parameters should be used in calculating the EEDI for these ships. In the container ship with a carrying capacity of 10000 TEU, [22] show that the gains in terms of EEDI using the waste heat recovery (WHR) method in the low-speed ship diesel engine. Using WHR method, the EEDI value can reach up to 20% below the reference line.…”

“…In addition to emissions, new technologies used in ballast water treatment are expressed. Optimized sail using on ships provides energy efficiency, [22] developed the test model by using computational fluid dynamics. In terms of EEDI the model provides 4% gain for the ships that has sailing system also provides 18.2% gain for ships that hasn't any sails.…”

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 the beginning, the traditional vessel has a non-symmetrical arc-shaped sail with soft sail material. Indeed, this profile has good aerodynamic performance [8,9]. However, a previous study explained that the rigid sail has a higher lift coefficient than the soft sail [7].…”

“…Besides, after the oil crisis, the rigid sail has been proposed to be applied for several ships, in which ships with rigid sail succeeded in reducing the fuel consumption by around 10% [7]. Recent studies stated that optimizing the hard wing-sail in sail-assisted vessels could improve energy efficiency [8]. Hence, this research determines the effectiveness of wing-sail technologies, such as fowler flap assisted sail for a 108 meters Tanker.…”

The use of fossil fuels on commercial ships significantly contributes to the increase of carbon dioxide emission, and adaptation of renewable energy can help control that emission efficiently. Historically, the extraction of wind energy is found to be the best renewable energy solution for commercial ships; and recently, with renewed interest in this area, various wind energy extraction devices are proposed in the literature. This study investigates the effectiveness of one such technology, wing-sail, on a tanker ship. The NACA 4412 series is adopted to design the sail in this regard, and a fowler flap is added to aid the sail in low wind speed. ANSYS Fluent is used to carry out this CFD simulation-based study. The effects of onboard wing-sails under various apparent wind angles, wind speeds, and wing-sail orientations have been examined. The impact of wing-sail on the stability of the ship is also analyzed. It is concluded that the ship can save fuel and reduce carbon dioxide emissions by 1.8% to 2.4% while using the wing-sail with the aid of a fowler flap. Also, this combination of wing-sail with the fowler flap is found to be the best in providing extra thrust for commercial ships without significantly sacrificing its stability.

This scoping review assesses the current use of simulation-based design optimization (SBDO) in marine engineering, focusing on identifying research trends, methodologies, and application areas. Analyzing 277 studies from Scopus and Web of Science, the review finds that SBDO is predominantly applied to optimizing marine vessel hulls, including both surface and underwater types, and extends to key components like bows, sterns, propellers, and fins. It also covers marine structures and renewable energy systems. A notable trend is the preference for deterministic single-objective optimization methods, indicating potential growth areas in multi-objective and stochastic approaches. The review points out the necessity of integrating more comprehensive multidisciplinary optimization methods to address the complex challenges in marine environments. Despite the extensive application of SBDO in marine engineering, there remains a need for enhancing the methodologies’ efficiency and robustness. This review offers a critical overview of SBDO’s role in marine engineering and highlights opportunities for future research to advance the field.
