Field of research: Fatigue Strength; Fabrication Effects on Structural Behaviour
Duration: 01.09.2009 – 29.02.2013
Funded by: EU (FKZ 233980) – 64 partners, Coordinator: Fincantieri
Project Leader: Prof. Dr.-Ing. W. Fricke
Summary
Initiated by EUROYARDS, BESST aims to achieve a breakthrough in competitiveness, environmentally friendliness and safety of EU built ships. Focusing on passenger ships, ferries and mega-yachts, the results will to a large extend be applicable also to other ships. A holistic life cycle performance assessment on ship level will guide the technical developments on system level, clustered in System Groups. The results will be integrated in 3 virtual show cases (ship concepts) demonstrating technical solutions as well as life cycle impact compared to current designs. Optimization tools will be developed and applied in a cooperative process proving feasibility, adaptability and efficiency to future commercial applications.
The key areas of technical developments include:
• Space Optimisation and Easy Maintenance
• Improving Payload to Gross Tonnage Ratio
• Cost Efficient Building Processes and Refurbishment
• Improved Energy Efficiency and Reduced Emissions
• Noise and Vibration
• Improved Reliability through Model-Based Design and Condition Monitoring
• Optimization of Logistic Chains
• Improving Safety and Security
The Institut for Ship Structural Design and Analysis is involved in WP 05-II-1 including fatigue tests for the assessment of laser and laser-hybrid welds and associated computations.
