Il contesto in cui operano i maggiori EPC Contractor attraversa un periodo di trasformazione; la crescente complessità degli impianti, nuovi Player localizzati in particolare nel Far East e la riduzione dei tempi di realizzazione, intensificano la competizione internazionale stimolando le aziende a riadattare la propria strategia. Tecnimont risponde a queste esigenze tramite il progetto “Design to Cost”, in cui si inserisce il seguente elaborato di tesi, che approfondisce le tematiche della modularizzazione e della standardizzazione di alcuni componenti utilizzati in un impianto, al fine di incrementare le performance economico temporali. Nella prima fase, l’analisi si è focalizzata sulla comprensione dell’attuale processo di gestione dei supporti per tubazioni, dal Design alle attività di installazione in Site, trattati come elementi “Itemizzati”. Successivamente è stato elaborato il modello, in cui il concetto di “Bulk Material Management” viene applicato ai supporti. I sotto-componenti, che costituiscono le tipologie dei supporti primari, sono stati individuati per poi essere standardizzati in termini di dimensioni, profili, materiali e modalità d’utilizzo, al fine di ridurne il più possibile la variabilità. Il modello si fonda su Design Practices & Rules ottenute dall’analisi concreta di sei differenti impianti recentemente realizzati e su considerazioni costruttive riferite a normative internazionali, valutandone i benefici in termini di riduzione di materiale e di semplificazione dei codici merceologici. Inoltre, la logica Bulk è stata integrata in primo luogo con i documenti impiegati nel Workflow dei supporti, e successivamente con l’architettura Software esistente per la progettazione e gestione degli stessi. La standardizzazione consente di acquistare i sotto-componenti prodotti in serie presso fornitori specializzati. Attraverso la collaborazione con un’azienda metalmeccanica, è stato elaborato un secondo modello che consente di individuare quei mercati dove sia conveniente acquistare i supporti, in luogo dell’attuale procedura di sub-appaltarne la fabbricazione ad un sub-contrattore. I modelli elaborati e le metodologie applicate hanno validità generale. Vengono quindi presentati l’estensione del processo di modularizzazione ad altre tipologie di componenti strutturali ed i risultati conseguiti. Nell’ultimo capitolo viene illustrato un Concept futuribile per la gestione dei supporti, che consentirebbe una trasformazione radicale dell’intero processo, richiedendo però un investimento economico e tempistiche maggiori rispetto all’orientamento strategico del progetto “Design to Cost” che Tecnimont ha intrapreso.

Abstract
The main EPC Contractors’ background is going through a period of deep transformations; the growing plant complexity, new Players from Far East and the reduction in the realization period, intensify the international competition, encouraging the companies to re-adapt the own strategy. Tecnimont meets these needs through the “Design to Cost” project, where the following thesis work is inserted, which deepens the components Modularization and Standardization theme, in order to increase the economic and temporal performances. In the first part, the analysis has been focused toward the understanding of the actual piping support management workflow, from the design phase to the installation, dealt as items. Subsequently the model has been developed, where the “Bulk Material Management” concept is applied to the supports. The sub-components, which make the different typologies of supports, have been identified and standardized in terms of dimensions, profiles, materials and ways of using, in order to reduce the variability as much as possible. The model is based upon Design Practice & Rules derived from the analysis of six different plants recently realized and upon constructive considerations referred to international regulations, evaluating benefits in terms of material savings and commodity codes simplification. In addition, the Bulk approach was integrated firstly with the documents used in the support’s workflow and after with the software architecture employed for support design and management. The standardization allows to buy the sub-components mass manufactured from specialized vendor. Through the partnership with an Italian manufacturing company, a second model was developed in order to identify the markets in which it is convenient to buy the supports, instead of the actual procedure where the supports are pre-fabricated by an on Site sub-contractor. The developed models and the applied methodologies can be generalized. The extension of the modularization process to other structural components and the achieved results are presented in the study. In the last chapter a futuristic concept is shown for supports management, which could allow a radical transformation of the entire process, but requiring an economic investment and a greater time period compared to the strategic orientation of the Design to Cost project undertaken by Tecnimont.File | Dimensione | Formato | |
