C1 - Structural Integrity in the Marine Environment (corrosion, fatigue, coatings etc.)

C - Materials and Manufacturing

Status - published
Last updated on: 26/03/2020

Challenges/Opportunities

Corrosion and Fatigue degrade structural integrity and need to be better understood.

Solution

Experimental, Numerical and analytical damage models need to be developed, validated and verified for offshore structural integrity.

Context And Need

Need

Offshore/marine renewables are subject to harsh deployment environments; corrosion fatigue is the primary progressive damage mechanism adversely affecting structural integrity and hence safety and LCoE; New markets, including USA and China, include extreme deployment conditions

Breakthrough

Breakthrough needed to enhance understanding of corrosion fatigue mechanisms.

Summary

Offshore wind components/assets need to withstand the harsh marine environment hence understanding of degradation mechanisms should warrant operability and safety of personnel.

Impact Potential

Expected potential impact is high in CAPEX/OPEX/survivability and safety.

Research Status

Joint Industry Projects over the past 4-5 years have mainly tackled such issues, informing fatigue assessment practices. However issues remain concerning corrosion fatigue, in particular:

  1. EPSRC CAMREG project
  2. Carbon Trust Projects
  3. Major Delft Corrosion Project
  4. SLIC
