“…In oblique and vertical flows, the ROV can maintain stability in a flow environment of 0.9 m/s while maintaining horizontal thrust. (2) The horizontal thrust of the propeller decreases with the increase of flow velocity, but the relationship between thrust and flow velocity is not linear and the rate of thrust decline is lower than the theoretical value. The vertical flow also decreases the horizontal thrust of the propeller.…”

“…With the exploitation of marine resources, the construction of cross-sea bridges [1,2], offshore wind power [3], and maintenance and repair (IMR) operations [4] has started to develop towards deeper waters. Consequently, deep-water pile foundations are developing towards having larger diameters [5,6] to cope with complex marine environments.…”

In recent years, Remotely Operated Vehicles (ROVs) have played an increasingly important role in the construction and monitoring of underwater pile foundations. However, due to the open frame structure of such vehicles, a gap of knowledge still exists with regard to their hydrodynamic behavior. In this study, the hydrodynamic stability of such vehicles is investigated numerically by means of a multiple reference frame method. The hydrodynamic characteristics of the ROV when it moves horizontally and upward in the vertical plane are examined. It is found that there is interference between the horizontal and vertical thrusters of the ROV. There is also interference between the propeller thrust and drag (or lift). The effect of the vertical thrusters can increase the horizontal thrust by about 5%. The horizontal thrusters create a low-pressure area below the body, which can make vertical drag experienced by the ROV significantly higher.

“…ROVs are operated by a human operator using a remote control, and they are tethered to a surface vessel, which supplies power and communications. ROVs can be used for deep-sea exploration, search and rescue operations, and underwater construction and maintenance [2]. AUVs are self-propelled and operate without human intervention, AUVs are used for mapping the ocean floor, oceanography, and marine biology research [3].…”

This study aims to design a new hybrid twin autonomous underwater vehicle (HTAUV) consisting of dual cylinder hulls and analyze its pitching motion. The kinematic model for the HTAUV is established, followed by the execution of hydrodynamic simulation CFD of the HTAUV using Ansys Fluent. These simulations are conducted to obtain the hydrodynamic force equation of the HTAUV, which relates to the deflection angle of the elevator. Through the motion simulation of the HTAUV, under the same net buoyancy condition, notable differences emerge when the elevator is deflected. Specifically, parameters such as gliding speed, gliding angle, and pitch angle of the HTAUV are larger when the elevator is deflected, as compared to cases where no deflection is applied.
