heal.abstract	The objective of this thesis is the design of a floating dry dock with a lifting capacity of 20,000 tons. Preliminary design and dimensional specifications are defined using Analysis and Design of Floating Drydocks, by Amirikian Arsham (1), while the structural assessment of the dock will be performed in alignment with IACS class - American Bureau of Shipping, Rules for Building and Classing Steel Floating Dry Docks. 2022. (2), and is divided in two stages. The first stage involves performing analytical calculations to verify that the proposed dock’s design meets the specified regulatory requirements, covering a dimensional review, local strength testing of primary structural components, and assessments of longitudinal and transverse strength within permissible limits. The design process also includes the development of a 3D structural model using Rhinoceros, alongside a comprehensive stability analysis conducted with AVEVA Marine. These elements ensure the dry dock’s stability and structural integrity under operational conditions, accounting for all critical loading factors and safety requirements. The second stage applies Finite Element Method [FEM] using ABAQUS Finite Element Analysis [FEA] Software by SIMULIA to assess structural integrity. This process involves defining part properties, assembling components, creating a mesh grid, and setting up loads, constraints, and boundary conditions before program execution. The resulting data are evaluated based on Von Mises equivalent stress against the maximum allowable threshold established by the regulation (2).	en
