Prevent external and internal corrosion of wind turbines structures
Supporting the renewable energy market
Computer-aided designs of cost-effective corrosion protection systems
The support structures and foundations are vital parts for offshore wind turbines to ensure the continuity of operations. Following regulation requirements asking for computed based modeling of cathodic protection systems, Elsyca's solutions support the offshore wind farms industry to:
Quickly and accurately analyze internal and external corrosion phenomena;
Develop, by mean of computer-aided design solutions, effective corrosion protection systems including Sacrificial Anode Cathodic Protection (SACP) or Impressed Current Cathodic Protection (ICCP);
Ensure compliance with regulations.
Our expertise and solutions are currently protecting more than 1700 wind turbines worldwide.
Covering all aspects of corrosion protection
Whatever the corrosion protection method (ICCP or SACP), quickly assess the protection level and the local current density on the structures. Corrosion prevention and maintenance teams can:
optimize anode configurations and coating coverage;
evaluate time-dependent effects like coating degradation and calcareous deposit formation;
predict the service life of sacrificial anodes;
plan and budget retrofit programs;
evaluate ROV inspections more accurately;
Corrosion can also appear in internal closed compartments. Elsyca's solutions for cathodic protection computer-aided design and analysis allow considering all internal conditions parameters affecting corrosion growth rate including:
dissolved oxygen and chlorine;
pH-values and potentials.
Follow recommended practice
International guidances on the development of CP systems recommend the use of computer-based modeling solutions to:
demonstrate the number and location of electrodes is adequate;
demonstrate the protection of the structure;
assess the adequate potential distribution;
consider the time-dependent relation between cathodic current demand and protection potential.
Whatever the structure type, we bring visibility and understanding on corrosion status and protection efficiency
Elsyca's solution optimizes the Sacrificial Anode Cathodic Protection (SACP) or Impressed Current Cathodic Protection (ICCP) systems of submerged structures considering:
structure geometry ;
seawater velocities and resistivity;
water refreshment and retention time;
gas venting rate (H2, O2, and Cl2);
change in water chemistry (pH, conductivity, bicarbonate, and carbonate).
