Static and Dynamic Analysis of eROV Mechanical Design using CFD

Abstract

Technological innovations in the marine field have developed rapidly in the last decade. One of it is the innovation in the technologies related to the underwater research and exploration. It has been driven by the need of the a flexible, reconfigurable, and reliable machine for underwater operation termed Remotely Operated Vehicle (ROV). The ROV development has opened up many opportunities in the observation and exploration of underwater environment. The most important aspect in the ROV is the flexibility of motion during the maneuver in the water. The mechanical structure and also the static and dynamic analysis is very important aspect in designing ROV related to its operation environment. This paper proposes ROV body design based on analysis characteristic hydrodynamic and buoyancy effect using CFD. The characteristics of each fluid flow affect the motion of the ROV which movement is driven by the thrusters. The hydrodynamic characteristics and buoyancy effect will be analyzed. The result will be used in the further mathematical calculations in the controller design phase.
