  • The use of remotely operated underwater vehicles (ROVs) is set to increase all over the world in the years to come, driven by the growing needs of the offshore industries (Oil & Gas, MRE) and the communications sector (intercontinental cable laying projects). The Ecole Centrale de Nantes is participating in a project that aims to improve the entire chain of operations leading to the launching and recovery of a ROV.

    These operations of launching and lifting the ROV-TMS assembly are critical, in particular during severe environmental conditions with possibly strong waves, high wind speeds, and strong current. The design of the ships and the Launch and Recovery System (LARS) must be carried out accounting for the forces encountered during sometimes violent events with flows likely to damage equipment or disrupt operations.

    The hydrodynamic problem is complex (proximity of the ROV to the hull, movements of the ship and the ROV), it is therefore necessary to set up a calculation chain which makes it possible to couple the generation of waves to the hydrodynamic and mechanical solvers, but also to anticipate other aspects such as control. The scope will be further specified according to the needs of the project.

    The numerical simulation will focus on a ship with a handling device of the ROV-TMS system, i.e. a LARS, considering several configurations.

    The modeling will be done in 2 phases, first using linearized models built on the potential flow theory, which represents the basic element of the codes used in naval engineering to take into account the interactions between the structure and the environment. From this first phase, remarkable conditions will be identified and the study will be extended using a "Computational Fluid Dynamics (CFD)" code which is more expensive but which makes it possible to consider the complex problem and to have a better understanding of the flow at the local level. The CFD codes preselected for this activity are a version of the OpenFOAM opensource code developed in the laboratory which has specific functionalities for the generation of sea states thanks to the coupling with the potential nonlinear code HOS-NWT.

    We are looking with a candidate holding a PhD, with experience in Naval Architecture and/or Ocean Engineering. Previous experience with OpenFOAM would be greatly appreciated

    Benefits

    Minimum 31500 Euros /year gross salary, can be higher with experience
