               3.3. ROV power cabin design
               This section presents the shell structure and internal support structure of the search and rescue ROV control
               cabin and power cabin for the 200 m water depth operation, and the theoretical calculation and ANSYS finite
               element analysis of the strength and stability of the shell structure are carried out.
