“…To reveal the dynamic characteristics of the floating systems, the coupled hydrodynamic-structural responses were investigated by Chen et al (2023), using a frequency-time-domain numerical model with viscous correction. At present, the use of finite element analysis to study the stress state of the target structure is relatively common (Nugroho et al, 2020;Alegre and Tremblay, 2022;Li et al, 2022). The detection of ship mooring loads is mainly based on the stress monitoring of mooring facilities (Yu and He, 2018;Wu, 2019;Liu M W et al, 2020) and the model-based dynamic load calculation (Dev, 2018;Yang et al, 2021).…”

Due to the sea water intrusion and the development trend of using large-scale ships, more stringent requirements are put forward for the safety of water delivery process and the mooring equipment operation for the sea shiplock. The maximum loads for the mooring equipment of sea shiplock, i.e., floating mooring column (FMC), are generally occurred at the end of water delivery. The superimposed effect of turbulent flow and marine corrosive environment can accelerate the failure of the floating mooring column structure for the sea shiplock, which leads to the safety incidents, including the structural damage of FMC and the breakage of mooring lines for the ship, etc. The safety of the FMC is mostly influenced by three factors, including the ship’s tonnage, the water flow environment of the locked room, and the lock operation technologies; among these, the water flow environment can be considered the most significant. In practice, because the mooring load of an FMC due to water delivery from the shiplock is very complicated, there is currently no mature approach to condition monitoring. This investigation aims to address a large sea shiplock, and the optimal regulation approach for water delivery of shiplock is established based on a load monitoring methodology for FMCs. The detection accuracy of the FMC mooring loads is controlled by simulation verification with errors less than 10%. During the optimized water delivery process, the exerted loads on the FMCs are noticeably reduced to be lower than the maximum design rating. The innovative approach is essentially based on an inversion calculation of the load response model for obtaining the mooring loads of FMCs, with the monitored load results used to regulate and optimize the water delivery process of the shiplocks. The research results can fill a part of the research gap of FMC mooring load condition monitoring method in shiplock water delivery, and provide technical support for the safety of shiplock water delivery process and mooring equipment operation.

“…Scholars have made many efforts to reduce fuel consumption and greenhouse gas emissions. Modification of hull form in the preliminary and early-stage design is categorized as a potential solution to obtain the optimal hydrodynamic performance aspects, including propulsion, resistance, stability, and seakeeping [13][14][15][16][17][18]. The shape of the hull underwater will affect the fluid flow characteristics around the ship, representing a drag movement.…”

A typical ship must operate in extreme conditions in the open coastal zone. Due to the severe operation at sea, comparative research on the design of the hull shape for optimization purposes will be important, specifically in the resistance and movement aspect. In this regard, an investigation was carried out by varying the total of four V-shaped monohull models from the high-built design as the main subject to compare several hull shape designs at the same displacement to obtain better performance at stability, resistance, and seakeeping criteria. Savitsky formula is used to calculate the hull resistance, and the stability analysis is calculated analytically by comparing the relationship between righting arm and heel angle. Moreover, ship motion is investigated by examining heave and roll response amplitude operator (RAO) and Motion Sickness Incident (MSI) index due to wave height 0.1 m. The most significant feature in this study is resistance since, with limited power, a minimum resistance value is necessary for best outcomes. It can be found that Model I is a superior model in terms of resistance, stability, and seakeeping performance to other models. However, Model III is not recommended since it has high resistance and bad stability and motion performance. From these results, it can be summarized that Model I is selected as the best hull form model.
