LIUTO
Development of a public transport vessel with low environmental impact characteristics
OVERVIEW
- A low generation of waves and wash
- An attenuation of the noise
- A significant decrease in polluting gas emissions and fuel consumption
The Dept. of Naval Engineering (Univ. of Naples) identified and tested a hull design satisfying the objectives, while Schottel and SVA finalised the design of the azimuthal propulsion system, with blades constructed in carbon fibre composite. MARIN refined the hull design by exhaustive computer simulations and basin tests. The resulting design achieves a reduction of up to 30% in wave generation and an increase of up to 15% in propeller efficiency. Based on these results INTERMARINE constructed the hull and the superstructure using a purpose tested fibreglass material and its patented manufacturing process.
PARTICIPATING PARTNERS
- ACTV – Azienda Consorzio Trasporti Veneziano, Italy (Co-ordinator)
- INTERMARINE S.p.A., Italy
- MARIN – Maritime Research Institute Netherlands, Netherlands
- Schottel-Werft Josef Becker GmbH & Co., Germany
- SVA – Schiffbau-Versuchsanstalt Potsdam GmbH, Germany
- Department of Naval Engineering, University of Naples, Italy
The project has been managed by Ing. Attilio Brighenti, Italy, now President of S.A.T.E.
CHARACTERISTICS
- Length: 24.75 m
- Breadth: 4.95 m
- Light ship displacement: 37 t
- Passenger Capacity: 230 (of which 100 seated)
The innovative characteristics of the vessel are:
- Reduction in wave and wash generation
- Better manoeuvrability and energy saving
- Reduced maintenance costs
- Reduction in noise emissions
- Reduction in polluting gas emissions via the use of the hybrid energy system
