ABSTRACT
The present experience feedback is related to the “SiNuS” project, jointly funded and operated by shipbuilders in the Nantes area and IRT Jules Verne. The project aims at developing advanced numerical tools to tackle the vibro-acoustic response of marine plateforms (e.g. cruise or navy ships) with more precise physical models and more efficient numerical procedures. The innovations have been successfully developed within a collaborative framework, involving experts from academia and industry.

INTRODUCTION
Developing ever more precise (incorporating ever finer physics) and rapid (using computing resources accessible to engineers and designers) calculation methods is a constant need for many mechanical engineering manufacturers, particularly in the shipbuilding sector, for example to meet navy specifications and shipowners' requirements in terms of the acoustic signature of ships.
Given the complexity of computing techniques, the constraints on their use and the cost of developing new methods, it is sometimes appropriate for industrial players to carry out their R&D in a collaborative context, involving multidisciplinary teams of academic researchers and industrial engineers.
The example of the "SiNuS" project, dedicated to the development of advanced numerical methods for the shipbuilding industry, provides feedback from a collaborative project funded by two shipbuilding manufacturers in the Nantes region and the IRT Jules Verne.
