Structural Design and Hydrodynamic Coefficient Calculation of Observation-class ROVs

Remote Operated Vehicle (ROV) can replace humans in inspecting and maintaining water facilities such as reservoirs and dams. Connected to surface support equipment through umbilical cables, the umbilical cable allows the operator to control the ROV's operations remotely from a mother ship or shore. Using the ROV as an underwater operational platform, precise and efficient underwater inspection and repair operations for hydraulic structures can be achieved by mounting underwater mechanical arms, pan-tilt cameras, cleaning and cutting devices, etc. This paper designs an observation-class ROV, carries out structural design of the ROV body, selects and models sensors and actuators according to actual needs, and provides a method for using the FLUENT software to perform hydrodynamic calculations and obtain hydrodynamic coefficients based on the model.
