Special Issue Information

Dear Colleagues,

The needs of the building of new ships, driven by both economic and environmental aspects, require an ever higher level of specialization of the ships. This translates into the improvement of operational capabilities related to the intended objectives.

In this regard, it is essential to improve the predictions of the behavior of ships in rough seas in terms of safety, comfort and power efficiency.

Safety in adverse sea states passes through the study of the new approach and criteria on the dynamic stability of the ship as well as the study of loads and structural response in waves.

Enhancing the knowledge of the ship's performance in waves, in terms of accelerations, speeds and ship motions both in navigation and maneuvering, allows us to analyze and optimize not only the comfort on board but also the performance of the ship in terms of energy saving.

Therefore, this Special Issue is proposed as an improvement of the analysis and forecasting techniques, through experimental, numerical and simulation techniques, aimed at analyzing the stability, hydrodynamics, ship motions and structural responses of marine vehicles. Therefore, this Special Issue will be an opportunity to provide guidelines and case studies to help designers to find strategies for the optimization of the performance and safety of marine vessels in heavy seas.

In this work, the dynamics of a planing hull in regular head waves was investigated using the Smoothed Particle Hydrodynamics (SPH) meshfree method. The simulation of the interaction of such vessels with wave trains features several challenging characteristics, from the complex physical interaction, due to large dynamic responses, to the likewise heavy numerical workload. A novel numerical wave flume implemented within the SPH-based code DualSPHysics fulfills both demands, guaranteeing comparable accuracy with an established proprietary Computational Fluid Dynamics (CFD) solver without sharpening the computational load. The numerical wave flume uses ad hoc open-boundary conditions to reproduce the flow characteristics encountered by the hull during its motion, combining the current and waves while adjusting their properties with respect to the vessel’s experimental towing speed. It follows a relatively small three-dimensional domain, where the potentiality of the SPH method in modeling free-surface flows interacting with moving structures is unleashed. The results in different wave conditions show the feasibility of this novel approach, considering the overall good agreement with the experiments; hence, an interesting alternative procedure to simulate the seakeeping test in several marine conditions with bearable effort and satisfying accuracy is established.

An approach combining frequency and time domain analysis is introduced in this study for ship motions assessment. The open-source NEMOH code is utilized to compute the excitation forces and the hydrodynamic coefficients, while heave and pitch motions time histories are determined by solving the Cummins equations in the time domain. The study compares the numerical outcomes for the heave, pitch, and vertical acceleration at the center of gravity with data obtained from a smartphone onboard during an oceanographic expedition in the Antarctic Ocean in early 2020 on the “Laura Bassi” research vessel. In order to validate the proposed method, weather forecast data from the global-WAM (GWAM) model are utilized. The comparison reveals a good agreement between numerical results and onboard measurements, with differences in motion values remaining below 10% and accelerations below 15%. Therefore, the developed code, taking into account its future improvements, represents an initial step towards creating a promising tool for an accurate estimation of ship motions and accelerations.

The employment of fixed hydrofoils on existing planing craft is becoming a widely investigated topic, thanks to the opportunity of reducing the total drag forces and the consumptions of main engines, with a positive impact also in terms of air pollutant emissions in the atmosphere. The design of fixed hydrofoils for planing craft is investigated after developing the wing hydrodynamic model, capable of capturing the main forces acting on the craft longitudinal plane. An iterative procedure is developed to solve the nonlinear equilibrium equations and detect the minimum thrust configuration of the fixed hydrofoils at the cruise speed. The new iterative procedure allows investigating the entire design space of fixed hydrofoils and detecting the best configuration for both new and existing craft, with a positive impact in terms of time effort amount and design efficiency. A simplified seakeeping model is also developed to evaluate the impact of fixed hydrofoils on the craft hydrodynamics in a seaway. The USV01 planing craft is assumed as reference for the case study. The wing optimization procedure is employed and the seakeeping analysis in the foil-borne mode is subsequently performed by a set of dedicated codes developed in Matlab. The obtained results are discussed and some suggestions for the reliable design of fixed hydrofoils are provided. Full article

Amid a global effort in reducing the shipping ecologic impact, the study of the particular case of added resistance of high speed vessels cruising in a seaway has been approached by a very limited number of authors. In this study, we provide a comprehensive and systematic assessment of the added resistance of a planing hull in regular waves. The data are analyzed in both the time and frequency domains in order to fully characterize the added resistance and highlight its correlation with hull motions. It is found that peak added resistance modulation occurs for shorter waves with respect to the peak average added resistance, and slenderness is beneficial only in terms of modulation. Nonlinearity of both the average and first harmonic amplitude is also shown. In addition, results of the phase analysis show a correlation between the added resistance phase and average added resistance. Full article

The rescue of ships in distress at sea relies mainly on rescue vessels, which includes the approaching process and the towing motion of the two ships. Ship rescue can be reduced to a two-ship problem, primarily involving the relative motion between ships during rescue. We established a mathematical model of ship motion based on the viscous fluid N-S equation, and the approaching process of two Wigley ships under waves was simulated in a two-dimensional plane. Then, according to three-dimensional potential flow theory, the coupled motion response model of the ships under six degrees of freedom was constructed, and calculation models of wind, waves, currents and other environmental disturbance factors were established to numerically calculate the towing motion. The results show that the upstream vessel has a lower heave motion amplitude and higher roll motion amplitude during the approaching process; A ratio of 1.5 times the width of the ship is the critical area where the motion of the two ships interacts with each other; For the berthing process, the faster the motion of the active vessel is, the lower the motion amplitude will be for both upstream and downstream vessels. When towing under rough sea conditions, changes in wave height and towing velocity have a large influence on the coupling effect of the towing system. When towing, head-on waves and low sea conditions are preferred, and the velocity should be sufficiently high to reduce the influence of cable self-weight on the towed ship. According to the simulations, the recommended velocity range is 3–5 m/s. Finally, a ship model scaling model was developed based on the similar quasi-Froude number of the ship model test, and the simulation results were verified by conducting parallel and towing tests of the model in a basin with a spherical wave-maker device.
