ENDURANCE by RESEARCH

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)
