Project

Cathodic protection for offshore wind structures

Publisher

Supervisor

Location

Greater Copenhagen area

Almost all offshore wind turbines are founded on steel structures, each typically weighting around 1000t. These structures are severely subjected to fatigue loading and since fatigue resistance is highly reduced by corrosion the structures are protected against corrosion and the main corrosion protection of these structures is cathodic protection. Usually cathodic protection was provided by galvanic anodes (GACP) but due to cost reduction, restrictions to design and pollution from emission of metal ions cathodic protection is now increasingly being established from impressed current systems (ICCP).

The methods for design of especially ICCP systems for offshore Wind structures are poorly documented leading to overly conservative designs or to not-calculable risk of protection failure which makes corrosion protection by cathodic protection and especially ICCP systems more expensive and less attractive. Thereby cost for offshore wind energy increases and reduced possibility for reducing pollution from metal ions released by sacrificial anodes. By establishing satisfactory design methods for offshore cathodic protection systems offshore wind energy will become more attractive which will reduce global impact from power production and be beneficial to the large Danish offshore industry.
