Structures
• Materials (metals, plastics, composites)
• Bonding (adhesives, welding, mechanical bonding)
Influence of maritime environment on materials and structures
Environment
• Atmospheric (C5M)• Tidal zone
(wet/dry cycle, radiation, temperature)
• Immersed zone (sea water, temperature, pressure)
Protection/MitigationSolutions
• Protective layers• Durable materials• Active systems (ICAF, cathodic
protection, ultrasound, UV)• Chemicals• Monitoring
Degradation
• Chemical degradation (corrosion, ageing)
• Biological degradation(aerobic/ anaerobic)
