Key action 3 Land transport and marine technologies
3.2.1. Efficient, safe and environmentally friendly ships and vessels
Objective : _
The main objective of the SHIPD project is to provide an integrated analysis tool for marine design, based on CFD technology. The actual approach in ship design is to consider separately the hull, the propeller and the appendages. The SHIPD Project consists in an integrated approach where the ship propulsion will be considered as a whole set. The improved physical models of ship-propeller interactions, cavitation, free surface and turbulence will be integrated in the CFD analysis. Significant effort will be directed to the validation of the numerical computations with experiments carried out at different scales to ensure their relevance to the full-scale end-user applications. Finally, the re-design of an existing ship propulsion and the design of a new ship propulsion will be carried out as test cases for evaluating the end product.
 PROPOSAL TITLE : SHIPD
Integrated Hydrodynamic Design for Ship Propulsion
 SUBJECT :
Development and validation of CFD tools dedicated to new vessels design and optimisation of propeller-hull interactions.
 PROJECT DESCRIPTION
- Proposal outline :
The SHIPD Project will consist in the integration of the knowledge and available technologies of the different European partners to develop application by marine design engineers (HSVA, NAOS, SVA). The SHIPD Project will be focused on the integrated hydrodynamic design process of a ship propulsion. The problem of hull-propulsion system interaction will be treated with the existing CFD code(AEA). The state of the art physical models for cavitation (EPFL, ARMINES), free surface waves (HSVA and SVA), and turbulence (IMFT) will be will be integrated around one of the leading European CFD codes (AEA) which has been engaged for several years in the computation of ship and ship/propeller flows. Experiments for the validation of the software will be performed by three of the leading experimental facilities in Europe, EPFL High Speed Cavitation
Tunnel, the HSVA Large Cavitation tunnel and the large Towing Tank Facility (SVA). The experiments will include basic situation such as an oscillating hydrofoil in cavitation tunnels, reduced scale hull-propeller arrangement and full scale sea trial for the same hull-propeller arrangement. All the relevant data for the CFD validation will be measured such as thrust, torque, cavitation and pressure fluctuations of the propeller. A close analysis of the CFD results by comparison to the experimental data will be performed.
The design, analysis and evaluation of ships as well as the integration of the ship and propulsion system are carried out by design offices (Naos) and specialized consulting companies (HSVA, SVA). As a reference case, an existing ship propulsion arrangement will be studied according to the state of the art approach and, then, the developed software package will be applied to the same arrangement. The comparison of the two

approach will lead to an evaluation of the project. Finally the effectiveness of the end product will be checked trough the design of a new merchant ship (Naos).

 PARTNER PROFILE SOUGHT
- Required expertise :
The required shipyard partner must have a large experience in shipbuilding concerning medium and large sized vessels and expertise in use of CFD tools.
- Description of the work carried out by the partner sought :
The partner will participate to the definition of a test case to be carried out by the partner to validate the developed software. The partner will also provide, at the end of the program, a project to be carried out simultaneously in his own shipyard with his traditional tools and by the partners using the developed integrated software. A comparison of the results obtained by the two approaches will be realised to asses the validity of the new concept.
