Special Issue Information

Dear Colleagues,

The structural design of ships is undergoing significant transformation as the maritime industry embraces sustainability, digitalization, and vessel specialization. This Special Issue seeks to consolidate recent advances in the design, analysis, and intelligent monitoring of both conventional ships and emerging vessel types, including smart ships, autonomous vessels, podded propulsion ships, and fuel cell-powered ships, as well as cryogenic carriers for LNG, LCO2, and LH2.

These advanced ship types demand robust structural integrity, high-performance insulation systems, and reliable thermal-mechanical behavior to support safe and energy-efficient operations. In addition to new paradigms, this Special Issue welcomes studies on traditional structural concerns, such as fatigue analysis, collision and grounding effects, ultimate strength assessment, and fluid-structure interaction (FSI) under complex loading conditions.

Simultaneously, the integration of Digital Twin technologies, real-time structural health monitoring (SHM), and AI-based design automation—utilizing deep learning, Transformer models, and natural language processing (NLP)—offers innovative tools for predictive diagnostics, performance enhancement, and life-cycle optimization of ship structures.

We welcome original research and review articles addressing theoretical modeling, experimental validation, and regulatory-compliant structural solutions that can drive innovation in modern ship design.

This paper presents an optimisation study to determine the best centre of gravity (CoG) position to improve seakeeping performance. Two varied parameters used in this study were the longitudinal and vertical centre of gravity (LCG and VCG). The Radius Gyration in the y-axis (Ry) is introduced as a novel single-objective function to be minimised, avoiding the complexity of the conventional seakeeping optimisation process. The quality of the seakeeping performance was evaluated by response amplitude operators (RAOs) of the heave, pitch, and vertical motion. Two different hull forms are compared to investigate the applicability of the Ry as the objective function in seakeeping optimisation. The patrol boat and S-60 hull form are selected as representatives of a planing hull type and a displacement hull type. The optimisation was carried out by using the Central Composite Design (CCD) and response surface methodology (RSM) to model the relationship between the CoG and Ry from large and small vessels, with the objective function minimising the Ry. The finding shows that minimising the Ry is more sensitive to the planing hull type compared to the displacement hull type in reducing the vertical motion in different Froude numbers and wave headings.
