Summary: The purpose of this paper is to establish assessment procedures for the fire safety of Ro-Ro ship cargo spaces using suitable design fires. Representative heat release rates for common types of passenger cars and heavy goods vehicles (HGVs) are determined based on data from fire experiments involving vehicles. The methodology involves extending an existing mathematical scheme for generating parametric heat release rate curves to handle vehicle fire scenarios. A case study is conducted to demonstrate the methodology, focusing on investigating fire propagation on the vehicle deck of a Ro-Ro ship using the Fire Dynamics Simulator (FDS) code.

Summary: Urban road tunnels are a reasonable solution to congested road traffic inconveniences but also bring specific threats, including the possibility of fire outbreaks. Through a case study of selected tunnels in Poland, it was estimated that low-power tunnel fires could occur in the next 10-20 years, while the chances of disastrous fire accidents were also assessed.

Summary: The Safety of Life at Sea (SOLAS), established in 1914 after the Titanic disaster, sets mandatory requirements for ship safety, including the use of watertight bulkheads. Despite advancements in safety technologies, ship accidents still occur. This study proposes a Buoyancy Support System (BSS) designed according to ISO 23121-1 and ISO 23121-2, aiming to reduce the risk of sinking or capsizing in case of flooding while considering construction costs, weight increase, and vessel stability.

Summary: As the IMO aims to reduce greenhouse gas emissions from ships by more than 50% by 2050 compared to 2008, the shipbuilding and shipping industries are undergoing a paradigm shift. The use of carbon-free fuels and electric propulsion systems is progressing, and the verification of reliability and safety is crucial. However, maritime demonstration is time-consuming and expensive, thus a more efficient means of demonstrating carbon-neutral technologies in ships is required. This study proposes a ship design for marine demonstration, integrating eco-friendly fuels and electric propulsion systems.

Summary: This study investigated and compared the compression responses and energy absorption capacities of coral sand and silica sand at a strain rate of approximately 1000 s-1. The results showed that coral sand had significantly higher energy absorption capacity than silica sand due to its higher compressibility. The study findings suggest that using poorly graded coral sand can improve its energy absorption capacity.

Summary: This study investigates the double-average turbulence characteristics of combined wave-current flow over a rough bed with different spacing arrangements. The results show that a spacing ratio of p/r=4 offers the highest resistance to the flow, and the double-average Reynolds stress decreases throughout the flow depth. The advection of momentum-flux of normal stress shows an increase at the outer layer and a decrease near the bed region after wave imposition. Maximum turbulence kinetic energy production and diffusion occur at different layers. The turbulence structure is strongly anisotropic at the bottom region and near the outer layer, with a decrease in anisotropy observed with an increase in roughness spacing.

Summary: The deep-water bridge is more vulnerable to earthquake damage than the bridge standing in air. The larger blocking ratio has a significant impact on the added mass coefficient, which requires further comprehensive study. The generation mechanism of block effect is analyzed using numerical simulation software ANSYS Fluent. The results show that the recirculation zone with focus reduces the pressure on the back surface of the cylinder, resulting in the peak value of in-line force not occurring synchronously with the peak value of acceleration. The change in position and intensity of the recirculation zone with focus, as well as the change in water flow around the cylinder surface, are identified as the generation mechanism of the block effect, which has a 10% influence on the hydrodynamic force. The changing rule of the added mass coefficient with blocking ratio is discussed in detail, and a modification approach to the current added mass coefficient calculation method is suggested. Physical experiments are conducted to validate the modification approach, and the results show that it is accurate and can be used in further study and real practice.
