Hydrodynamic loads on a restrained ROV under waves and current
Ocean Engineering, 2021 Remotely Operated (underwater) Vehicles (ROV) have a wide range of maritime applications, including repair and maintenance. Quantifying hydrodynamic loads is important for the design and control of these ROVs. A novel approach with eight tethers was used

Dynamic positioning of ROV in the wave zone during launch and recovery from a small surface vessel
Ocean Engineering, 2021 Dynamical positioning (DP) control of a remotely operated vehicle (ROV) using thrusters is investigated as a means to increase operability of its launch and recovery system (LARS) on relatively small surface vessels. The ROV uses its DP control system to

Modeling of Remotely Operated Vehicle (ROV) Operations for Aquaculture
2023 IEEE International Conference on Mechatronics and Automation (ICMA), 2023This paper proposes an extensive model for unmanned underwater vehicle operations in aquaculture and includes a dynamic 6 degrees of freedom (DOF) quaternion-based model of a remotely operated vehicle (ROV) and a model of a net cage structure.

P2-ROV is a portable polar ROV. Designed to be transported via-helicopter and easily handled by a small team of scientists it is specially addressed to work under the shelf ice of Antarctica by exploiting the holes drilled in the ice by means of a special 350 mm auger; the shape of the vehicle reminds that of a torpedo contained in a 340 mm diameter ...

Hierarchical NMPC–ISMC of active heave motion compensation system for TMS–ROV recovery
Ocean Engineering, 2021This study reveals the operating risk of cable breaking when the TMS–ROV recovery is carried out beneath rough ocean waves. To release the negative impact of the support vessels vertical heave motion on the station-keeping and position tracking ...

On the Mathematical Modeling of ROV'S
IFAC Proceedings Volumes, 1991Abstract Remotely operated underwater vehicles (ROV’s) are important tools for inspection and maintenance tasks in off-shore engineering and for submarine structures as well as for exploration and exploitation in deep sea mining. The communication, power, and control connection to the operation basis is usually performed by means of a tether cable ...

Development and Experiments of a Novel Deep-sea Resident ROV
2021 6th International Conference on Control and Robotics Engineering (ICCRE), 2021It is extremely difficult and expensive to operate a traditional remotely operated vehicle (ROV) in the deep-sea. In this paper, a novel small-scale deep-sea resident ROV, called Rover ROV, is designed to conduct regional fine-sounding operations.
