“…It is known that modernization requires significant investment, while the ship owner's funds are often limited. Unlike previously considered studies on the fleet modernization [5,[8][9][10][11][12], the proposed strategy makes it possible not only to comprehensively improve the technical characteristics of a vessel but also to ensure the profit gain as a result of their implementation, thereby ensuring the modernization effectiveness.…”

“…Paper [12] examines alternative concepts for improving the energy efficiency of cruise vessels by modeling the operation of vessels equipped with different new energy generation systems. The study revealed that double-pressure steam systems, the use of low-temperature water have the greatest potential to ensure the reduction of fuel consumption and to improve the energy efficiency of cruise vessels.…”

“…The typical configuration for a fully electric cruise ship, with size 140,000 GT similar to the one investigated herein, is depicted in Figure 1. Cruise ships of that size account for a considerable part of the overall tonnage of the cruise ship fleet and are identified as representatives high-efficiency conventional cruise ships [34].…”

The shipping industry has been facing increasing challenges due to the stringent regulations for anthropogenic emissions limits, the new targets for carbon emissions reduction and the potential carbon pricing introduction. These have led to an upsurge of activities towards improving the environmental footprint of cruise ships. This study investigates the impact of carbon pricing on the cruise ships optimal power plant configuration. Mathematical models are used to estimate the performance of the cruise ship energy systems. A novel bi-objective optimisation method for the cruise ship energy systems synthesis is developed, which employs the Non-Sorting Genetic Algorithm II optimisation algorithm and uses as objectives the Life Cycle Cost and the lifetime carbon emissions. Cruise ship configurations that perform optimally under carbon pricing scenarios while complying with the air emissions regulations are identified. The results show that the baseline configuration does not belong to the optimal solutions. Solutions including carbon capture, waste heat recovery and dual fuel generator sets that operate with natural gas or methanol can reduce drastically the carbon emissions. The optimisation identified solutions that reduce the Life Cycle Cost by 40% compared to the baseline configuration despite increasing their capital cost, whilst reducing of the carbon emissions more than 37%.

“…Because of these reasons, two strategies such as finding the renewable energy sources [3] and technical solutions for emission management for the improvement of the effectiveness in the use of energy and the environmental protection are essential [4]. Among emissions emitted into the air from the fossil fuel combustion of diesel engines, sulfur emission (SOx) is a dangerous pollutant and it is complicated to control [5], [6]. In the exhaust line of engines, SOx reacts to water under the appropriate conditions to form sulphuric acid, resulting in negative impacts on materials (corrosion) and environment (acid rain).…”

Pollution in the maritime field is considered as such a serious problem that scientists, policymakers, and managers are always urged with a desire to find solutions and strategies one way or another to minimize its negative impacts on the environment and the life. Among the effective solutions, the use of fuels with limited-sulfur content or bio-based fuels has been paid much attention to due to their advantages in the use of marine diesel engines. In the current study, a type of fossil diesel fuel with ultra-low sulfur content (ULSD) was mixed with coconut oil (CO) through the ultrasonic treatment under the changes in volume fraction of as-used fuels, the correlation on viscosity selected the rate mixing between ULSD and coconut oil. After 12 minutes of ultrasound treatment, the highest stability of the ULSD-CO emulsion was achieved correspondingly to 97.8% for a mixing rate of 76%(ULSD):24%(CO) along with the distance of 85mm from the containing-vessel bottom to the ultrasound horn tip. Moreover, the spray characteristics including penetration length and a cone angle of ULSD, CO, and ULSD-CO emulsion were also examined and compared to diesel fuel. The similarity of spray characteristics to diesel fuel, containing ultra-low sulfur content and oxygen content, renewability are considered as some advantages of ULSD-CO emulsion as used for diesel engines aiming to meet the stricter requirements of IMO regulations about the strategies of environmental protection.
