Special Issue Information

Dear Colleagues,

Reducing the environmental impact of CO2, sulfur and nitrogen oxide emissions is a major challenge for maritime activities and the shipbuilding industry. The ecological energy transition is being promoted in the maritime sector in order to achieve carbon neutrality by 2050. The International Maritime Organization (IMO) has already adopted mandatory measures to reduce the greenhouse gas (GHG) emissions produced by shipping following the United Nations Sustainable Development Goal n° 13, which is to "take urgent action to address climate change and its impacts". These actions aim to reduce the GHG emissions produced by marine activities as soon as possible. These objectives have motivated a complete rethinking of the energy and propulsion systems of ships in order to reduce their impact and optimize their efficiency, operation and reliability. This Special Issue will focus on new solutions regarding the energy and propulsion systems of ships. This Special Issue aims to share knowledge through innovative theoretical and experimental contributions that address ideas, recent developments, or mature solutions regarding this topic. This involves integrating new low-carbon energy sources (e.g., hydrogen, alternative fuels, storage systems, renewable sources, etc.) and hybrid and electrical propulsion systems onboard existing and future ships. Another crucial aspect is the integration of novel solutions that aim to enhance efficiency in terms of hydrodynamics (new kinds of propellers, drag reduction, etc.).

The design of the stator and nozzle of a rim-driven pumpjet thruster (RDPJ) is addressed through a simulation-based design optimization approach built on a parametric description of the main geometrical characteristics of the system, a RANS solver with actuator disk model, and a genetic algorithm. As the propeller blades’ geometry is fixed, the rotor/stator (RDPJ-R/S) configuration is considered for the optimal design from a multi-objective optimization process aimed at minimizing the resistance keeping the cavitation inception index at the lowest possible value. Steady-state (moving reference frame plus mixing plane interface) and unsteady simulations (sliding meshes) with fully resolved rotor geometry were finally carried out on six selected optimal geometries to validate the optimization process and the performance improvements provided by the RDPJ configuration when compared with the original rim-driven thruster (RDT).

The growing use of proton-exchange membrane fuel cells (PEMFCs) in hybrid propulsion systems is aimed at replacing traditional internal combustion engines and reducing greenhouse gas emissions. Effective power distribution between the fuel cell and the energy storage system (ESS) is crucial and has led to a growing emphasis on developing energy management systems (EMSs) to efficiently implement this integration. To address this goal, this study examines the performance of a fuzzy logic rule-based strategy for a hybrid fuel cell propulsion system in a small hydrogen-powered passenger vessel. The primary objective is to optimize fuel efficiency, with particular attention on reducing hydrogen consumption. The analysis is carried out under typical operating conditions encountered during a river trip. Comparisons between the proposed strategy with other approaches—control based, optimization based, and deterministic rule based—are conducted to verify the effectiveness of the proposed strategy. Simulation results indicated that the EMS based on fuzzy logic mechanisms was the most successful in reducing fuel consumption. The superior performance of this method stems from its ability to adaptively manage power distribution between the fuel cell and energy storage systems. Full article

Maritime transport is the most widely used means of transporting goods, and forecasts indicate that it will continue to grow in the coming years, which is why the IMO is regulating energy efficiency and emissions from maritime transport with exhaustive monitoring. The most widely used measure of energy efficiency during operation on a ship is the Energy Efficiency Operational Indicator (EEOI); however, the difficulty in obtaining references for this indicator, together with the great variability that exists between shipowners when choosing terms such as “cargo transported”, among others, means that this operational indicator of energy efficiency in ships does not have the expected results. This work develops a two-phase procedure for the selection of representative EEOI values for ships, taking into account parameters such as ship speed, cargo, mode of operation and the subsequent determination of a suitable control system that allows the continuous and real-time implementation of measures to improve energy and environmental efficiency on the ship. The proposed final procedure is effective in terms of improving energy efficiency and emissions, on top of being simple, easily implementable, working in real time and adapting to navigation circumstances while keeping emissions under control.
