The Operational Unit (UO) INAV is active in the research and development fields regarding conventional and un-conventional, mobile and fixed marine units operating on the sea surface and underwater. Such fields can be identified in:
1. Hull shape development and optimisation;
2. Equilibrium and static and dynamic stability in water;
3. Motion resistance, propulsors and mutual interaction;
4. Sea keeping, manoeuvrability and dynamic positioning;
5. Static and dynamic analysis of structural loads and responses including fluid-structure interaction (FSI)
6. Reliability and safety of marine structures
7. Inspection, maintenance of marine structures, structural integrity and longevity in marine environment, degradation effects and prevention.
8. Noise propagation internal to the structure and external, in air and in water;
9. Technological process for marine constructions and for their management
10. Conventional and un-conventional materials and joints in intact and damaged state.
11. Innovative design methods and procedures
12. Technical Norms development and harmonisation at national and international level, in co-operation with the International Maritime Organisation (IMO), Flag Authorities, Classification Societies, etc.
13. Actuators and transmission gears for marine systems: design, innovative prototyping and test systems
14. Technical management in operation of marine structures during the whole life cycle.
15. Off-shore platforms for renewable energy production.
It is here underlined that most of the above subjects are in line with contents of Horizon Europe (HEU) 2021-27 for what concerns the sector of ship, boat and marine technology industries with reference to the subjects of Naval Architecture, marine constructions and plants.
Research activities can be validated by experimental campaigns, in particular those carried out in the labs: IDRO (Experimental Hydrodynamics Lab) featuring a towing tank and a cavitation tunnel for propeller tests.; MASTEL (Marine Structures Testing Lab); DREAMS (Drives and Experimental Automation for Marine Systems). The labs are equipped for surveys both at shipyards and on board.
Numerical activities for research and consultancy activities in the marine field are based on a proprietary HPC infrastructure (medium dimensions) or on the possibility of using large dimensions HPC infrastructures at national level.
