Examples of end-of-study projects in Naval and Offshore Architecture
To get a clearer idea of what an end of-study project in Naval & Offshore Architecture entails, here is an example of a thesis:
End of studies internship done at MARIN research center, by Paul B,, general engineer training, class of 2021
Extract :
"Liquid Natural Gas (LNG) terminals are built to offer easy access from deep water to incoming Liquid Natural Gas Carrier (LNGC). Yet, these configurations expose LNGC moored to the jetty to infragravity waves in tune with their natural frequency, leading to great amplitude motions that can endangered installations safety"
End of studies internship done at Subsea7, by Pedro Luiz DAF., general engineer training, class of 2018
Extract :
"The S-lay installation method has been used successfully for decades in shallow water and is used more and more for deep-water projects. With its high level of productivity, this method is preferred to J-lay installation method .Nevertheless, with the increasing number of field development in deep and ultra-deep water (<1500m), limits regarding pipeline integrity (bending moment in sagbend) and vessel equipment’s (especially capacity of tensioner i.e. maximum allowable top tension) are achieved quickly. In order to install pipe with S-lay method as deep as possible, the degree of conservatism (inherited mainly from common practice in offshore industry which are based on shallow water projects) in installation analyses should be decreased. Therefore, several parameters (that can have an impact on top tension and bending moment) have been studied: Drag Coefficient, Added Mass Coefficient, soil Stiffness, Seabed Friction Coefficient and length of pipeline on the seabed"

End of studies internship done at LHEEA, by Charles-Edouard J., general engineer training, class of 2018
Extract :
"The project conducted by LHEEA and CNR-INM focuses on the optimization of hull forms by minimizing the hydrodynamic drag. The optimizer (AMFM) and the modeler (KLE) were both developed by CNR-INM while the solver code used is ISIS-CFD. One aspect of the project is to minimize the calculation cost using automatic mesh refinement in order to limit the cell density in non relevant areas of the domain. The purpose of this work is to perfom a complete optimization chain to minimize the hydrodynamic drag for the DTMB5415."
End of studies internship done at Bureau Veritas Marine&Offshore, by Julieta Logarzo., general engineer training, class of 2018
Extract :
“Offshore units designed to stock gas, as gas carriers and FSRU, are submitted to extreme environmental conditions that cause efforts in the structure. In particular, units composed of independent tanks from the hull are submitted to efforts induced by friction in tanks supports. The present study is focused on the analysis of nonlinearities carried out by contact interaction between hull and tank.”
End of studies internship done at LHEEA laboratory at Centrale Nantes, by Matthieu Abgrall, general engineer training, class of 2024
Extract :
“This study investigates the use of adaptive grid reőnement for RANS-based seakeeping computations. It addresses the primary challenge of deőning an effective and reliable reőnement criterion and procedure for modeling a wide range of regular waves without iterative parameter adjustments.”
Examples of projects in Hydrography-Oceanography
This page presents examples of end-of-study internships completed in the sphere of Hydrography and Oceanography.
Stage de fin d’études réalisé à l'institut méditerranéen d'Océanologie par Domitille C., Formation d’ingénieur spécialité hydrographie océanographie, Promotion 2024
Extrait :
"Les flux de gaz sont primordiaux à estimer pour pouvoir étudier différents phénomènes et processus climatiques. L’objectif de ce stage est de diminuer l’incertitude des mesures des optodes à oxygène de chez Aanderaa® utilisées dans le programme BCG-Argo, afin d’estimer les flux de pCO2 , de pO2 et de chaleur en soufflerie LASIF, un milieu contrôlé permettant de reproduire des expériences."
Stage de fin d’études réalisé au laboratoire IRD par Arnaud C., Formation d’ingénieur spécialité hydrographie océanographie, Promotion 2024
Extrait :
"Mon projet de fin d’études s’inscrit dans le cadre du projet ANR APERO et de sa campagne éponyme mise en place pour « Estimer la production, l’export et la reminéralisation de la matière biogène marine : de la surface à l’océan profond ». Son but est d’étudier l’océan et sa capacité à être une pompe biologique de carbone. Lors de cette campagne des sondeurs acoustiques monofaisceau appelés "profileurs acoustiques" ont été déployés au sein de la colonne d’eau. Les transducteurs utilisés sont larges bandes. C’est-à-dire qu’ils récoltent des informations sur une gamme de fréquences et non une fréquence ponctuelle. Ces acquisitions innovantes permettent d’observer individuellement les organismes évoluant sous la surface et de les associer à une signature fréquentielle.(...) L’objectif est de travailler sur un protocole de traitement des données acoustiques de la campagne APERO. Pour cela, il sera nécessaire de prendre en compte l’ensemble des subtilités apportées par l’usage des profileurs acoustiques larges bandes."
End of studies internship done at LOPS, by Agathe C., general engineer training, class of 2021
Extract:
"This region is a transition zone between cold/fresh polar water near Antarctic coast and saline/warm subtropical water north of the ACC which is structured
in multiple thermohaline quasi-zonal fronts, varying in location, duration and size. Using 27 years of thermosalinograph measurements along a route between Hobart in Tasmania
and the french base Dumont d’Urville, this report aim is to document (sub)mesoscale thermohaline structure and associated processes at the ocean surface in the Marginal Ice
Zone, south of 60°S."
End of studies internship done at IUEM, byFlora G., general engineer training, class of 2021
Extract:
"Predicting the intensity and track of tropical cyclones (TC) is nowadays very important to reduce the damage caused by these extreme events. The crucial parameters for improving TC forecasts depend on the position of the tropical cyclone center. Synthetic Aperture Radar (SAR) images provide new observations and estimates of TC-generated winds speed and direction. In this report, a new method will be implemented to calculate the position of TC centers from SARderived wind directions."
End of studies internship done at Stockholms universitet, by Gaspard G., general engineer training, class of 2019
Extract:
“The purpose of this study is to observe internal tides in the ocean by using sonar technology. While the dynamics of internal waves mainly take place in the ocean interior, they also have a small surface expression. We have used the High Resolution Empirical Tide Model, based on satellite altimetry, to compute this surface expression for theM2semi-diurnal tide globally. Based on vertical mode decomposition, we have then estimated the correspondingmode-1 interior isopycnal displacement. On the basis of this knowledge, we explored two acoustic datasets.”
End of studies internship done at LEGOS, CLS, Mercator Ocean International, by Perrine B., general engineer training, class of 2019
Extract:
"In the ocean, internal tides generation occurs when barotropic flows interact with strong topographic gradient, like ridges, in a stratified ocean, which create isopycnal heaving at tidal frequency. Internal tides can dissipate locally or after thousands of kilometres of propagation, whereas their dissipation produces vertical mixing at centimetric to millimetric scales. Their centimetric signature in sea surface height is measured by altimetry. How to separate these scales from (sub)mesoscale circulation is a challenge for both ocean models and for the future SWOT mission, which will provide altimetry data at resolutions never reached before on a large swath. This work contributes to better understand internal tides properties and their interaction with small scale circulation by using already existing altimetry data and a 1/36° resolution NEMO regional simulation to study the Vitoria-Trindade ridge in the South Atlantic, which has been identified as hotspot for internal tides generation."
End of studies internship done at CSIC, by Morgan P., general engineer training, class of 2019
Extract:
« During the INSIGHT-Leg 1 cruise in which I participated, high-resolution bathymetric data at depths up to 5000m were obtained through the use of an AUV, as well as geological and geophysical data obtained from R / V "Sarmiento de Gamboa". The rest of the internship was dedicated to the processing of the data acquired by the AUV ».
End of studies internship done at ISTerre, by Auriane H., general engineer training, class of 2019
Extract:
" Since 2007, GPS stations record the movements of the Argentière glacier. GPS data processing, which was first based on a static positioning (positions averaged every 6h), is now based on a kinematic positioning (positions computed from the simultaneous record that is made of visible satellites every 30s). Kinematic positioning has a better temporal resolution than the static one.During this internship, GNSS data have been processed via the software TRACK, and Python scripts have been developed to compute vertical displacements and horizontal speeds. Resulting time series have been compared to various observations in order to better understand the glacier’s movements"
