Special Issue Information

Dear Colleagues,

Marine transportation plays a crucial role in global trade; the performance of modern marine vehicles has significantly improved over the past few decades, largely driven by IMO regulations. In addition, the demand for high-quality food and stable energy supplies brings new applications and challenges for ships and marine vehicles. As a result, researchers and engineers are striving to develop advanced technologies to improve the performance of modern marine vehicles in alignment with the rapid expansion of industry trends, including IoT, data mining, digital twin, AI, etc.

This Special Issue aims to bring together cutting-edge research and insights from experts in the field, focusing on improving the performance of modern marine vehicles in both design and off-design conditions. Subsequently, it will cover a range of topics related to marine vehicle performance, including (but not limited to):

  • The design and optimization of hull forms for improved hydrodynamic performance;
  • The development of innovative propulsion systems, such as wind-propulsion, hybrid-electric and fuel cell systems;
  • The prediction method and control technology of ship vibrations and underwater noise;
  • The prediction and protection of ship shock vibration and noise;
  • The application of composite materials in the ship’s design;
  • Novel technologies for reducing GHG emissions and improving fuel efficiency;
  • Emerging technologies for ship performance monitoring;
  • The prediction of marine vehicle performance in a seaway;
  • The optimization of ship operation;
  • Data analytics in maritime applications.

We hope this Special Issue will provide a valuable resource for worldwide researchers, engineers, and practitioners working in the marine vehicle engineering and design field. We believe the articles in this issue will inspire new ideas and innovations, leading to further advancements in the performance of modern marine vehicles.

Since the variable-speed seawater pump and the three-way valve of a ship’s central cooling system are forms of feedback from the same output signal, these controllers may cause interference when they are not coordinated. Therefore, studying an efficient control tuning method for a central cooling water system is necessary. In this study, a central cooling water system is modeled using Matlab Simulink by utilizing an actual operation dataset, and unknown parameters are estimated for fine-tuning. The simulation model is then verified using the second operating dataset. Additionally, transfer functions are developed for the freshwater output temperature against the three-way valve openness input and the electrical power frequency input to the seawater pump motor, supposing that the two systems are independent. Then, the two PI controllers are tuned using internal model control (IMC) filters. Moreover, the modified internal model control tuning method is suggested, using the character of the central cooling system, which has a large time constant for the heat exchanger system with the seawater pump and a small time constant for the three-way valve system. This method simplifies the tuning of the two combined PI controllers, enhancing the seawater pump’s overall efficiency and the three-way valve’s operation. This study presents the proposed tuning methods based on the IMC filter and modified IMC guide, which confirmed the simple determination of the gain values of the PI controller with the efficient control of the rotational speed of the seawater pump and the three-way valve with reasonable control of the freshwater outlet temperature.
