Special Issue Information

Dear Colleagues,

This Special Issue aims to explore ground-breaking advancements in maritime technologies, with a primary focus on key themes such as sustainable ship technology, cutting-edge ship design, digital twin technology, shipyard production innovations, and the end-of-life treatment of vessels.

The maritime industry is currently undergoing significant transformations, propelled by an increasing emphasis on sustainability, efficiency, and lifecycle management. Sustainable ship technology, which encompasses inventive propulsion systems, energy-efficient designs, and environmentally friendly solutions, plays a crucial role in addressing environmental concerns and complying with stringent regulations.

Advancements in ship design extend beyond traditional methods and now integrate state-of-the-art principles in hydrodynamics, materials science, and structural engineering. The incorporation of digital twin technology emerges as a pivotal facilitator, offering a virtual replica of physical assets throughout their lifecycle. This enables the real-time monitoring, predictive maintenance, and optimization of ship performance, contributing to heightened safety, reliability, and operational efficiency.

Shipyard production techniques are undergoing a paradigm shift with the implementation of advanced manufacturing processes, automation, and digitalization. This Special Issue explores the latest methodologies employed in ship construction and reveals how technological advancements streamline production, reduce costs, and enhance overall productivity.

Additionally, this Special Issue sheds light on the end-of-life treatment of ships, which is a critical concern. As vessels approach the end of their operational lives, their responsible and sustainable disposal is imperative. The Special Issue therefore discusses environmentally friendly strategies for ship recycling, waste management, and the repurposing of materials, with the aim of minimizing the carbon footprint of maritime activities.

By uniting diverse perspectives and the latest research findings, this Special Issue aims to offer a comprehensive overview of the evolving landscape of maritime technologies. Researchers, engineers, and practitioners in the field will discover valuable insights into the multifaceted challenges and opportunities associated with sustainable ship technology, advanced ship design, the application of digital twins, shipyard production techniques, and end-of-life treatment.

A Type 22 Broadsword class of frigate uses a combined gas or gas (COGOG) propulsion system that utilizes four different gas turbines, depending on the mode of operation. Its twin ST40M cruise gas turbines are operational most frequently, and an increase in their efficiency would significantly impact fuel usage and ship range. This study evaluates the option to upgrade the cruise gas turbines to a combined gas turbine–electric and steam (COGES) system, which utilizes a steam Rankine cycle to recover energy from the exhaust gases of the gas turbine. An alternative system using hot air is also analyzed for performance comparison. The analysis contains calculations for the energy extraction and dimensions of heat exchangers, for the power extracted from the additional steam or air turbine and for pressure losses of the exhaust gas. Different configurations for the heat exchangers were investigated, as well as various parameters for the steam and hot air. The size and mass of the system were an important aspect of the analysis. It was concluded that an auxiliary system operating at a maximum steam pressure of 20 bar could generate an additional 771 kW of power while adding a mass of 7.4 tons to the frigate. These findings suggest that upgrading to a COGES system could cover the electricity needs of the entire ship and thus reduce the overall fuel consumption, resulting in lower operational costs and less emissions.

The crane installation on the deck of a yacht redistributes the stress field and affects the local structural integrity and performance. The safe operation of the yacht is associated with the optimal placement of the crane on the deck and the proper local structural reinforcement. Here, the structural analysis of the bow part of a yacht made of composite materials is studied, considering the retrofit installation of a crane, in three different cases of reinforcing the deck: (a) without any reinforcement, (b) with a T-type reinforcement, and finally, (c) with a longitudinal beam. The T-type connects the longitudinal bulkhead and the deck, reinforced locally with overlamination skin and adhesive-filler. The longitudinal beam works as a local longitudinal stiffener attached to the deck and connects the second, third, and fourth transverse frames. The structural analysis is performed using the finite element method following the classification societies’ rules. The local reinforcements are made from the same composite materials as the unreinforced deck. The maximum deformations, the principal stresses, and the safety factors following Tsai-Wu and Hashin criteria are calculated and compared for the three different cases. The T-type and longitudinal reinforcements reduce deck stresses by 33%, with longitudinal reinforcement reducing deck deformation by 17%. Composite failure analysis shows the structure was near failure, and the reinforcements enhance safety; T-type is better for multiaxial loads (Tsai-Wu), and longitudinal is superior for micromechanical failure (Hashin). By considering the structural performance and safety aspects, designers and engineers can make optimal decisions regarding yacht crane installation and proper reinforcement, leading to safer and more efficient structures.

This paper introduces a rigorous and comprehensive approach to the assessment of marine shafting systems through the utilization of an advanced π-Theorem-based scaling methodology. Integrating journal-bearing similarity assessment and shaft-line scaling methodology with advanced dimensional analysis, the study aims to provide a methodology foundation for systematic replication and analysis of marine shafting systems through scaled models. The proposed scaling methodology ensures geometric and mechanical similarity in terms of shaft-line deflection, considering key scaling parameters such as shaft length, diameter, weight, loads, rotational speed, material properties, bearing locations, and offsets. The advanced dimensional analysis computes specific non-dimensional ratios to guarantee a close resemblance between a real-size system and a scaled lab model. The methodology is analytically derived and validated with numerical simulations for a case study, conducting comparative analysis, evaluating discrepancies, and utilizing the integrated framework for experimentation.

To accommodate the production and manufacture of complex and customized marine components and to avoid the empirical nature of process planning, machining operations can be automatically sequenced and optimized using ant colony algorithms. However, traditional ant colony algorithms exhibit issues in the context of machining process planning. In this study, an improved ant colony algorithm is proposed to address these challenges. The introduction of a tiered distribution of initial pheromones mitigates the blindness of initial searches. By incorporating the number of iterations into the expectation heuristic function and introducing a ‘reward–penalty system’ for pheromones, the contradictions between convergence speed and the tendency to fall into local optima are avoided. Applying the improved ant colony algorithm to the process planning of large container ship propeller shaft machining, this study constructs a ‘distance’ model for each machining unit and develops a process constraint table. The results show significant improvements in initial search capabilities and convergence speed with the improved ant colony algorithm while also resolving the contradiction between convergence speed and optimal solutions. This verifies the feasibility and effectiveness of the improved ant colony algorithm in intelligent process planning for ships. Full article
