Ship-bridge collisions are one of the most common types of accidents, and bridge anti-ship collision devices are of great importance for bridge protection. First, a new type of assembled ultra-high performance concrete (UHPC) collision avoidance is proposed in this paper. The main components of the device are double-deck, two-way, densely reinforced ultra-high performance concrete floating boxes that are connected by high-strength bolts to form the whole structure and are equipped with steel supporting elements to form a collision energy dissipation device. The device is self-floating in water, is strongly energy absorbing due to plastic deformation, has a high degree of toughness, is corrosion resistant, and so on. This device also benefits from modular manufacturing, efficient installation, and easy replacement of damaged parts. Then, in this paper, the main parameters of the new collision avoidance, such as the material of the internal supporting elements, the wall thickness of the floating box, and the reinforcement ratio of the floating box, are optimized. Finally, a performance analysis and evaluation of the UHPC collision avoidance for the Honghe Bridge in Zhuhai City are carried out by using LS-DYNA program. The numerical results show that the new collision avoidance has significant advantages in reducing the ship–bridge collision force, prolonging the ship–bridge collision time, and protecting the ship. The results show that the assembled UHPC collision avoidance system is very effective for protecting ships and bridges in the event of a ship–bridge collision.

“…Fluid-structure interaction (FSI) methods have been introduced to integrate wind and wave effects into simulations, particularly by researchers focused on dynamic structural and aero-hydrodynamic interaction analyses. In a study by Song et al (2016), a comparative analysis of the FSI method to the constant added mass (CAM) methods using LS-DYNA software for an iceberg-floating structure collision analysis was conducted, validating their results against ice tank tests. Their study revealed that while the FSI method, coupled with a specific ice material model, yielded significantly more accurate results aligned with potential theory, it required an order of magnitude greater CPU power consumption compared to the CAM method.…”

Aging ships and offshore structures face harsh environmental and operational conditions in remote areas, leading to age-related damages such as corrosion wastage, fatigue cracking, and mechanical denting. These deteriorations, if left unattended, can escalate into catastrophic failures, causing casualties, property damage, and marine pollution. Hence, ensuring the safety and integrity of aging ships and offshore structures is paramount and achievable through innovative healthcare schemes. One such paradigm, digital healthcare engineering (DHE), initially introduced by the final coauthor, aims at providing lifetime healthcare for engineered structures, infrastructure, and individuals (e.g., seafarers) by harnessing advancements in digitalization and communication technologies. The DHE framework comprises five interconnected modules: on-site health parameter monitoring, data transmission to analytics centers, data analytics, simulation and visualization via digital twins, artificial intelligence-driven diagnosis and remedial planning using machine and deep learning, and predictive health condition analysis for future maintenance. This article surveys recent technological advancements pertinent to each DHE module, with a focus on its application to aging ships and offshore structures. The primary objectives include identifying cost-effective and accurate techniques to establish a DHE system for lifetime healthcare of aging ships and offshore structures—a project currently in progress by the authors.

“…According to the research of Song et al [2016] and Zong [2012], the added mass coefficient is independent of the magnitude of the excitation force. In this context, the force was 9.8 times larger than the mass of the ice floe and the excitation frequency was in a range between 10 rad/s and 50 rad/s.…”

In this study, the ice resistance of ship under the pack ice condition has been estimated using Multi-Material Arbitrary Lagrangian–Eulerian formulation and penalty-based fluid–structure interaction technique. Especially, the hydrodynamic loads occurring during the ship–ice interaction were combined in the numerical model, which could be important for simulating pack ice conditions. The feasibility of the hydrostatic and hydrodynamic performance in the fluid model was verified, respectively. By using an ice field generation algorithm to generate randomly distributed pack ices, the ice resistance of an oil tanker has been calculated and validated by comparing with the empirical formula. Moreover, the necessity to consider water effect in the interaction between ship and ice was also discussed.
