Proven technology for a new structure: Submerged Floating Tube Bridge

The lack of available spaces to locate new or larger infrastructures implies an effort in finding new areas to locate the transport system. A Submerged Floating Tube Bridge could be a feasible possibility to cross bodies of water, minimizing the use of land and avoiding deep tunnels. The structure is nowadays a feasible solution, thanks to the experience in the offshore field. Nevertheless, even if every part of the structure has a proven technology, the different parts have never worked together, so the final structure results to be a new crossing solution. This implies a problem of technology qualification, which requires a broader scope than traditional reductionist approaches to address uncertainties at the system level.
