“…LCL filters interfacing the converters and the AC bus are deployed following a design procedure from [13]. The load torque (T ) on the motor and the propeller thrust (F ) are both dependent on the rotational speed of the shaft (n), density of the water (ρ), and the propeller diameter (D) [14], [15].…”

With significant inroads being made in the electrification of land-based transport in recent years, there is an increased impetus on maritime transport as well for navigating towards cleaner fuels and reducing their emissions. However, the griddistant nature of marine vessels poses several challenges for their electrification not faced by their overland counterparts. This paper addresses some of these issues and outlines the role of power electronics in tackling them through onboard/onshore converters. Moreover, a hybrid energy interface feeding the ship's propulsion system and various loads is modeled and analyzed in a simulated environment wherein an intelligent control strategy is employed to optimize the use of onboard energy resources. Finally, some future trends are highlighted in the development of electric ships for making water transport emission-free.

The problems associated with the greenhouse effect have increased the desire to limit carbon dioxide (CO2) emissions into the atmosphere, including emissions produced by shipboard electrical power systems. This has led to a further search for solutions in this area, such as shipboard hybrid electric power systems (SHEPSs). These systems do not yet have a wide application compared with traditional shipboard electrical power systems for several reasons, including the lack of studies establishing the fault tolerance of such systems. Therefore, in this work, problems related to generated power quality deterioration under large disturbances are studied. To achieve the fault-free operation of SHEPS, an emergency prevention control (EPC) system based on controlled parameter forecasting, along with a system structure and operation algorithm, is developed. The goals of improving electrical power quality are achieved by increasing the control efficiency of the power system’s generating sources. To validate the feasibility of the proposed control system, a computer simulation was carried out after developing a mathematical model of the SHEPS under study. The results of the study show that the use of the proposed EPC system will improve power quality when the controlled parameters are within acceptable limits. At the same time, further research is needed, as the problem of false control action as a consequence of EPC system hardware or software faults remains unstudied.

“…Maritime transport plays an important role in global greenhouse gas (GHG) emissions, contributing approximately 3% of total emissions, comparable to the emissions of industrialized countries such as Germany and Japan [48]. Sector emissions are projected to increase by 17% if no changes are implemented by 2050 [8].…”

Maritime transport accounts for approximately 3% of global greenhouse gas (GHG) emissions with the sector aiming to achieve net zero by or around i.e. close 2050. There has been intense debate on medium-term measures that combine regulatory frameworks with financial incentives or economic penalties. Among the main proposals under discussion are a GHG levy, two flexible mechanisms (FCMs) based on the GHG Fuel Intensity (GFI) and a feebate. Despite extensive discussions on carbon levies, there is a notable lack of studies comparing the cost-effectiveness of these different GHG reduction measures in the maritime sector. This study aims to fill this gap by developing a comprehensive methodology to evaluate and compare these GHG policies. Using cost-effectiveness and multi-criterion decision analysis (MCDA), the study assesses the technical feasibility, economic implications, and environmental benefits of the proposed measures. The main quantitative results reveal that a GHG levy starting at $100 per ton of CO2 doubles fuel costs, while new fuels become economically attractive only after 2040 under the feebate mechanism. Both original and revised FCM proposals show similar cost patterns, with the revised FCM leading to earlier adoption of new fuels. We find that the FCMs and the carbon levy are effective in achieving the IMO's final and intermediate targets. However, FCMs are the most cost-effective proposals, achieving targets with the lowest present value of costs and the cost per avoided GHG emissions. The proposed methodology provides a robust framework for facilitating objective and structured discussions with stakeholders, helping to balance economic and environmental goals in maritime policymaking.
