Questa tesi presenta un'analisi completa dei parchi eolici offshore galleggianti, con un focus sull'area del Mediterraneo, in particolare l'Italia, e sulla modellazione tecnica delle relative opere secondo i modelli di costo. Inizia con una panoramica europea dei parchi eolici offshore, esaminando le potenziali ubicazioni dei siti e affrontando le sfide ambientali e normative specifiche del contesto mediterraneo. I capitoli successivi approfondiscono gli aspetti tecnici delle infrastrutture per l’offshore. Vengono esplorate le complessità della trasmissione di energia offshore, dettagliando come quest’ultima viene trasferita dalle installazioni a mare alla rete di trasmissione nazionale. Viene analizzata la progettazione e il funzionamento delle turbine eoliche, coprendo componenti critici come i generatori delle turbine, i convertitori e le configurazioni della topologia delle stringhe. Lo studio distingue tra strutture offshore fisse e galleggianti, sottolineando le sfide ingegneristiche e le soluzioni innovative uniche per ciascun tipo. La tesi indaga anche sui cavi marini, discutendo gli aspetti tecnici dei cavi dinamici, i loro accessori, le protezioni e i processi di installazione e posa dei cavi sottomarini. Un'attenzione significativa è posta sulla progettazione delle sottostazioni offshore galleggianti, che sono componenti cruciali del sistema elettrico offshore. Ciò include la progettazione della piattaforma (topside) e del ponte, nonché una panoramica delle apparecchiature di bordo. Il processo di dimensionamento dei componenti è dettagliato in modo approfondito, definendo i parametri del modello e presentando i risultati finali della progettazione. Lo studio si conclude con delle simulazioni volte a determinare i valori ottimali per i principali componenti elettrici all’interno del parco eolico offshore galleggiante. Queste simulazioni sono fondamentali per garantire la stabilità e l'efficienza del sistema di trasmissione dell'energia. Fornendo un'analisi inclusiva delle migliori pratiche ingegneristiche, questa ricerca offre preziose intuizioni per avanzare nello sviluppo delle infrastrutture energetiche sostenibili in ambienti marini.
