摘要

In this study, we aim to create a design methodology for the foundation and supporting structural modification of structures in the way of ship anchoring systems to suit all vessel types. Initially, the study follows a tug boat design (Indian Ports Association in Home-Indian Ports Association. Ipa.nic.in. https://www.ipa.nic.in/index.cshtml , [3]) of windlass foundation, chain locker, and anchor pocket supporting structures, with which a holistic approach is created. We use IRS class rules to determine anchoring equipment specifications and chain locker dimensions (Rules and regulations for the construction and classification of steel ships. https://www.irclass.org/media/7396/main_rules_july_2024-edition.pdf , [4]). Static analysis is used to identify loads acting at the foundations. A 3D model of the fore-end is generated using SOLIDWORKS, and finally, ANSYS is used for the FEM study. Various loads are identified, and an adaptable design methodology is created. The material selected is mild steel grade A (Rules and regulations for the construction and classification of steel ships. https://www.irclass.org/media/7396/main_rules_july_2024-edition.pdf , [4]).
