Votre mission

Au sein de l'entité "Brazil & Global Projects Centre" (GPC, le centre d'excellence de Subsea 7 pour la réalisation de ses projets de grande envergure dans le monde entier), le département "Structure Design" a en charge la conception et le dimensionnement des infrastructures offshore dans le secteur de l'énergie. Ce département se concentre principalement sur les champs en eau profonde: des ouvrages permanents aux aides à la fabrication et à l'installation. De plus, nous avons la capacité de soutenir des projets liés aux énergies renouvelables (offshore fixe, ou développement du flottant). Nos études couvrent ainsi l'ensemble d'un cycle allant de la phase conceptuelle en amont jusqu'à la phase d'exécution, incluant les étapes d'installation et de construction.

L'une des structures sous-marines les plus imposantes pour l'ancrage d'ouvrages flottants (éoliennes flottantes, bouées de déchargement, Riser Towers, FPSO, ...) ou le supportage de structures lourdes posées est l'Ancre à Succion. Il s'agit d'un ouvrage cylindriforme de grandes dimensions (jusqu'à plus de 1000m3) constitué d'une jupe à l'épaisseur optimisée, dont la susceptibilité au flambage local est questionnée pour le cas du transport en mer sous l'effet des accélération liées aux mouvements du bateau.

Dans une première phase, vous découvrirez les ancres à succion, les différents types et fonctionnalités puis leur processus de dimensionnement couvrant les phases de vie de l'ouvrage dont les méthodes de transport. Vous vous intéresserez alors à la problématique du transport en se concentrant sur la vérification de la jupe - ouverte ou pleine - vis-à-vis du flambage local. L'enjeu sera d'évaluer la résistance en fonction du rapport Diamètre OD sur épaisseur t de manière analytique après un inventaire des Codes/Règlements applicables, puis de corroborer les résultats avec une approche numérique (modèle coque, FEA avec ANSYS).

Your mission

Within the "Brazil & Global Projects Centre" (GPC, Subsea7's center of excellence for executing large-scale projects worldwide), the "Structure Design" department is responsible for designing and sizing offshore infrastructure in the energy sector. This department primarily focuses on deepwater fields, from permanent structures to Fabrication and Installation Aids. Additionally, we have the capability to support projects related to renewable energies (fixed offshore or floating development). Our studies cover the entire cycle from the conceptual phase to execution, including installation and construction stages.

One of the most impressive underwater structures for anchoring floating structures (floating wind turbines, offloading buoys, Riser Towers, FPSOs, etc.) or supporting heavy structures is the Suction Anchor. This is a large cylindrical structure (up to over 1000m³) with an optimized skirt thickness, whose susceptibility to local buckling is questioned during sea transport due to accelerations related to vessel movements.

In the first phase, you will discover the suction anchors, their various types and functionalities, and their sizing process covering the phases of life, including transport methods. You will then focus on the transport issue, focusing on verifying the skirt - open or plain - against local buckling. The challenge will be to evaluate the resistance based on the Diameter OD to thickness t ratio analytically after an inventory of applicable Codes/Regulations, and then corroborate the results with a numerical approach (shell model, FEA using ANSYS).
