“…Nowadays, with very dynamic development of autonomous systems, we can discover new possibilities of detecting, classifying and identifying possible threat [28][29][30][31][32][33][34]. The use of autonomous vehicles for harbour and seaway traffic lines monitoring is one of the most effective solutions for maintaining security awareness.…”

This article presents the information concerning aspects of the autonomous underwater vehicle (AUV) mission planning process, emphasizing maritime security monitoring and surveillance, and using side-looking sonars as a primary data source. The paper describes characteristic mission plan phases and gives suggestions for the operators, mainly concerning the safety and effectiveness of the AUV mission. The article describes the coverage path planning algorithm, which could be used to create an effective AUV mission plan, considering AUV manoeuvrability, sonar characteristics, and environmental factors. The results of the algorithms have been verified during the real mission of the AUV vehicle.

“…Through the fluid numerical simulation software ANSYS FLUENT 2020 R2, the water flow of a large ROV body under the condition of multi-degree-of-freedom motion was analyzed. The settings for the dynamic performance calculation for this numerical simulation of a three-dimensional steady-state flow are set to the following values [29]. The ROV structure body is long the unidirectional flow model is used to move underwater during the period, when determining the hydrodynamic performance of ROVs; the turbulence model selects the k-w model which takes into account the effects of low Reynolds numbers compressibility and shear flow dispersion.…”

Remotely Operated Vehicle (ROV) has been widely used in numerous underwater exploration applications such as exploration of complex deep sea environment, pipeline detection, installation, maintenance, and repair. Thus, it is worthy to design, optimize, and performance evaluation of ROV systems for underwater exploration purposes. Computational Fluid Dynamic (CFD) is a computational approach that is very helpful and widely used to examine the flow characteristics of ROV systems. In this research work, CFD analyses of ROV bodies with different thruster blades were carried out in order to generate thrust forces by the thruster blades. For this purpose, ANSYS FLUENT was used to examine the flow characteristics over the ROV body. The analyses were performed at different flow velocities, such as 1 m/s, 1.5 m/s, 2 m/s, 2.5 m/s, 3 m/s and 3.5 m/s. The outcomes were in the form of thrust force, drag force, pressure distribution, and velocity distribution. The result shows that four-blade thruster generates maximum thrust force as compare to other ROV thruster models. The main reason behind this higher thrust force is due to the larger motion of the fluid. Similarly, drag force was also investigated and observed that the drag force is greater for thruster model 3, having four blades due to the large frontal area of the ROV body and thruster blades. The results obtained in this study are very helpful for engineers and researchers to design and optimize ROV models using numerical methods.

“…A vehicle with a non-torpedo shape propelled by thrusters in the horizontal and vertical planes was presented by Szymak et al (2021) and simulated in 6-DOF. In the works of Horak et al (2020) as well as Maalouf et al (2015), Fossen's mathematical model was used to simulate the motion of a remote operated vehicle (ROV) with a complex shape geometry. In the work of Liu et al (2023), a model of a complex-shape underwater towed vehicle was presented with no propulsion system.…”

Hybrid propulsion in underwater vehicles is the new idea of combining conventional propulsion systems such as screw propellers with other kinds of propulsion like oscillating biomimetic fins, glider wings or jet thrusters. Each of these propulsion systems has its own benefits and drawbacks, and the goal is to have them complement each other in certain conditions. This paper covers the topic of a dynamic model of the pitch and heave motion of the HUUV (hybrid unmanned underwater vehicle) using screw propellers and biomimetic lateral fins. Firstly, the simulation model of the vehicle performing depth and pitch change is presented. Secondly, the vehicle's hydrodynamic coefficients obtained from CFD simulations are discussed. Thirdly, the results of the HUUV experimental studies in a swimming pool are presented. Lastly, simulation results are compared with those of the experiment to verify the correctness of the model. The vehicle's motion in the swimming pool during the experiments was recorded using a submerged camcorder and then analysed using the Tracker software.
