Title:  Internship - Structures Design - Hang off Collar

Location: 

Paris (Suresnes), FR

Job Closing Date:  17th Jan 2025

Votre missionn

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.

 

Un des éléments utilisés lors de l’installation en pleine mer de produit dit « flexibles » consiste en un dispositif boulonné appelé Hang Off Collar (HOC) en anglais. Cet éléments critique support à lui seul de quelques dizaines à plusieurs centaines de tonnes de tension dynamique.

 

Ce stage impliquera, dans une première phase, la compréhension des fonctionnalités de différents concept de HOCs ainsi que des charges auxquelles les éléments sont soumis. Vous recenserez ensuite les diffèrent HOCs utilisés lors de nos précédents projets afin d’établir une typologie des géométries et fonctionnalités utilisées. Vous établirez ensuite avec votre maître de stage une méthodologie, des outils d’étude et des documents de validations des HOCs par éléments finis sous le logiciel ANSYS. L’objectif recherché sera de concevoir et de vérifier tous les éléments constitutifs des HOCs le plus rapidement et efficacement possible.

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 elements used during the Offshore installation of so-called “flexible” products is a bolted supporting device called a Hang Off Collar (HOC). This critical element alone supports from a few tens to several hundreds of tons-equivalent of dynamic tension.

 

This internship will involve, in the first phase, understanding all the functionalities of different HOC concepts as well as the loads to which the elements are subjected. You will then list the different HOCs used in our previous projects to establish a typology of the geometries and functionalities used. You will then establish, with your internship supervisor, a methodology, study tools, and validation documents for the HOCs by the mean of finite element analyses with the ANSYS software. The goal will be to design and verify all the elements of the HOCs as quickly and efficiently as possible.

Votre profil

Ce stage est destiné à un-e étudiant-e ingénieur de dernière année, avec une formation en mécanique. Une solide connaissance du calcul des structures (charpente métallique) et de la résistance des matériaux est requise. La capacité à lire des plans (dessin industriel) est nécessaire pour ce stage.

Le-la stagiaire devra démontrer une bonne autonomie, être dynamique et rigoureux, tout en faisant preuve de créativité pour proposer des solutions innovantes et génératrices d'améliorations significatives.

Your profile
