Abstract: (18 Views)
The design of vessels and any structures used in water must be based on standard calculations in ship architecture and marine engineering, as the hull shape and geometry play a significant role in resisting the forces and moments acting on a vessel. In the present study, the vertical acceleration of two different stern forms of an oil tanker is investigated and compared by defining several similar nodes at the stern region. Since the dynamic motions of ships directly affect their behavior at sea, they can influence the safety of passengers and crew, cargo integrity, comfort levels, ship speed, and propulsion system fuel consumption. Therefore, reducing dynamic motions has always been a primary objective of ship designers. In this research, the canoa stern of an oil tanker was modified into a new curved transom stern, and the performance of both stern forms was evaluated using a simulation-based approach. First, the curved transom stern was designed using the Rhino commercial software. Subsequently, the vertical acceleration of each stern form was analyzed using Maxsurf marine software by defining several similar nodes in the modified stern regions. To ensure the validity of the modeling and analysis process, the results were compared with findings from previous studies. The results indicate that the curved transom stern exhibits superior performance compared to the canoa stern when subjected to dynamic hull loads and sea waves. In addition to reducing design and construction costs by approximately 13%, this stern form also leads to a reduction in vertical acceleration. Furthermore, the findings enable the identification of various desirable transom stern configurations or appropriate curvature angle ranges in the lower part of the hull, contributing to improved dynamic behavior of marine vessels.
