Interesting tidbit. According to Part 6 the lifespan of off-shore wind farms is now considered to be between 30-40 years:
"projects in 2011 would typically have assumed a 20 year operational life, but the industry has moved towards 35 years as a standard and some players now even expect that 40 years is achievable"
