Corrosion Protection of Offshore Wind Turbines-A Challenge for the Steel Builder and Paint Applicator

摘要

Corrosion protection is always the last step during a production process. When a job is behind schedule, there is often pressure on the paint shop to make up for lost time by hastening its part of the production process. Trying to solve these time-related problems by compromising the painting process, however, can create an extremely costly situation. The cost of painting off-shore structures in a paint shop is 15 to 25 ?Yn2 (depending on the setup of the workshop and the paint system). The cost of coating repair work performed on site, onshore (e.g., at a constructior site) is approximately 5 to 10 times more. But, if due to premature failure of the corrosion protection, repair work must be done offshore, the cost can increase to more than 1,000 ?/m~2. more than 100 times the cost of doing the job in the paint shop (with all job-related costs accumulated). The moral here is: Whatever your time problems may be, do not place them on the paint shop!
