In the context of underwater exploration of shallow waters, equipment such as ROVs (Remotely Operated Vehicles) or other robots are used. This underwater equipment requires the use of an umbilical that connects it to a surface control station. If passive, this link can be a barrier to mobility by involving an energy-intensive drag force, undesirable mechanical actions on the robot, risks of attachment to the marine environment and the creation of knots.

The objective of this thesis is to contribute to the management of subsea umbilicals by designing an intelligent umbilical system that can not only limit its undesirable effects on ROV navigation, but also be active and allow new piloting strategies to be implemented throughout the system.

The targeted application focuses on the case of an umbilical linking a surface drone and an ROV for a shallow observation and measurement mission near the coast. The entire system, which will be subject to marine currents, will have to operate in an environment of variable depth and possibly constrained by the presence of underwater topography, fauna and flora..

The impact on the marine environment will be taken into account throughout the design of this system.
