Hydrostatic test on tanks during the section stage of a ship: the case study of the PSV 5000

Abstract

In the modern shipbuilding, the construction and assembling of parts and block units are made far from the water, in specialized workshops / areas. In this way all the work is performed in a more efficient way, with the possibility of more accurate prediction of the delivery time and cost control. To move an activity in an earlier stage, before the launching of the vessel, represents a competitive advantage for the shipyard, namely the reduction of the risk of bottleneck and of any possible delays on the final delivery day with the saving of millions because of penalties. The objective of the present work is to study the feasibility to perform the hydrostatic test on tanks during the section stage of the construction. It is taken into analysis the case of the PSV 5000, the challenges and the advantages that it brings.
