Texte intégralThe goal of this thesis has been to present the legal conditions and social welfare of off-shore workers. Therefore, the main players have been studied in their various roles; from the many-faced employeurs to the ambivalent nature and status of the personnel. Certain workers are considered to sailors, oters land-side workers and even divers have their own particular category. The enormous variety of jobs and job duties explains the creation of highly individual work categories. It has also been noted that in cases of resignation, the contract law applicable is based upon international norms which are then adapted by the off-shore companies. This however does not eliminate all conflicts of jurisdiction, particularly as the off-shore personnel can excluded from those under the jurisdiction of coastel law. Secondly, the social welfare of off-shore workers has been examined. As the large majority of off-shore personnel work outside national territories, the definition social welfare jurisdiction has had to be redefined by national and communal mesures which cover both land workers and sailors. As to the claims for professional risks. The sailors coverage differs very little from the land workers. The status of a salaried employee on detached service and that of an expatriate salaried employee must also be taken into account

Texte intégralLo scopo principale di questa tesi è lo sviluppo di nuove metodologie per determinare l’affidabilità dei sistemi strutturali con applicazioni sia in campo offshore che aeronautico. In generale, strutture di interesse pratico sono caratterizzate da un elevato grado di ridondanza, per cui il collasso globale richiede la rottura simulatanea e/o progressiva di più elementi. Inoltre, i sistemi fisici sono influenzati da diverse fonti di incertezza, quali le prorietà dei materiali e le condizioni ambientali e operative. Pertanto, il collasso strutturale può avvenire con diverse modalità (modi di guasto), di cui solo alcune possiedono una probabilità di accadimento significativa (modi di guasto dominanti). Per una valutazione efficiente del rischio risulta dunque indispensabile limitare l’analisi ai soli modi dominanti, così da ridurre il costo computazionale associato alle fasi di identificazione e di valutazione dei modi stessi. Tuttavia, nonostante in letteratura vi siano numerose soluzioni per l’analisi del rischio, tali metodi richiedono ancora tempi di calcolo notevoli e sono inclini a tralasciare potenziali modi di guasto. Queste motivazioni conducono alla prima parte delle tesi, in cui si ripropone un metodo recentemente sviluppato per l’analisi del rischio di strutture discrete (reticolari e telai) in previsione di una sua applicazione al campo offshore. A tale scopo si considera il caso di studio di una piattaforma di tipo jacket in condizioni di mare estremo. Dapprima, i modi di guasto dominanti vengono rapidamente identificati per mezzo di un algoritmo genetico. In seguito, l’affidabilità del sistema viene calcolata mediante un approccio multi-scala che fa uso di semplici operazioni matriciali, in cui la dipendenza statistica viene considerata sia tra le componenti strutturali che tra i modi di guasto dominanti. Infine, l’accuratezza e l’efficienza del metodo vengono testate con successo tramite comparazione con Monte Carlo. Nella seconda parte della tesi, la teoria dell’affidabilità dei sistemi viene applicata per la quantificazione dell’incertezza nella resistenza a trazione di compositi UniDirezionali (UD), problema di notevole interesse per l’ambito aeronautico e non solo. Infatti, il comportamento aletorio di questi materiali è fortemente influenzato da effetti di scala, che limitano la progettazione di strutture in composito di grandi dimensioni sulla base dei dati sperimentali ricavati da provini. In quest’ottica, si propone di modellare fasci di fibre secondo una legge di scala gerarchica, ossia raggruppando un numero prestabilito di fasci più piccoli in un fascio di ordine superiore. La distribuzione di resistenza di tali fasci viene quindi simulata attraverso un’analisi di collasso progressivo. Questo approccio, dapprima validato rispetto ad un modello analitico recentemente sviluppato per disposizioni semplici di fasci, viene poi esteso a configurazioni più realistiche. I risultati così ottenuti sono infine processati per l’analisi statistica del danno.

Texte intégralThe structures built during the Seventies present a significant reserve of resistance in spite of the local failures observed. The objective of this research task is the examination of the impact of the through cracks on metal offshore structures made up of welded tubes. The idea is to model at the total level the effect of a through crack using a criterion of the type evolution of total potential energy or evolution of the displacement of a strategic node of the structure. Indeed, these structures, conceived in the Seventies, are very redundant and profit from a reserve of significant integrity. All the dubious or random sizes, length of crack, loading of swell. . . , are modelled and integrated by approaches of the probabilistic types. One use for that the method of response surfaces by coupling the mechanical analysis (Rouhan 1999) and the requests (Schoefs 1996)
