Based on the above, the management of spare parts can be very critical considering that relevant delivery time can last for several months, making it necessary to have a paradigm shift in manufacturing processes. Additive Manufacturing (AM) and in par- ticular the 3D Printing is an alternative to the traditional product manufacturing processes, where objects are designed by cutting and forc- ibly shaping raw material and constructing an object through the use of models and dyes. The additive manufacturing takes graphical data input from computer-aided manufacturing tools and cuts the data to serve separate object layers or components. In particular, the segmented/ layered graphical data is sent to a 3D printer, which applies the required combination of raw materials for that particular layer. The printer then adds up the product development layer by layer, stating form solid, liquid or powders, until it is completely designed and finished according to the design criteria. This approach applied to the Oil & Gas and Chemical industries could guarantee the opti- misation of warehouse and spare parts man- agement, decreasing the downtime or re-de- sign for the items in terms of shape, weight, corrosion-erosion resistance or facilitating a rapid prototyping supporting item technology improvement.

This manufacturing technology can bring remarkable advantages to the industry, such as the reduction of inventory value, the reduction of plant outages and the optimization of complex geometries. Xsight by Saipem (a Saipem Division) has established a collaboration with IMI Orton, the manufacturer of critical butterfly valves, and CMF Marelli, a 3D printing distributor in Italy, with the aim of verifying the potential of additive manufacturing in the realization of valves and valve components. L’Additive Manufacturing sta guadagnando continuo interesse nel settore dell’Oil & Gas. Questa tecnologia di produzione può apportare notevoli vantaggi all’industria, come la riduzione del valore del magazzino, la riduzione dei tempi di fermo inaspettato dell’impianto e l’ottimizzazione di geometrie complesse. Xsight by Saipem (Divisione di Saipem) ha stretto una collaborazione con IMI Orton, produttore di valvole a farfalla critiche, e CMF Marelli, distributore di stampanti 3D in Italia, con l’obiettivo di verificare in prima battuta il potenziale della produzione additiva nella realizzazione di valvole e componenti di quest’ultime.
