EVS-EN 61400-3:2009

This part of IEC 61400 specifies additional requirements for assessment of the externalconditions at an offshore wind turbine site and it specifies essential design requirements toensure the engineering integrity of offshore wind turbines. Its purpose is to provide anappropriate level of protection against damage from all hazards during the planned lifetime.This standard focuses on the engineering integrity of the structural components of an offshorewind turbine but is also concerned with subsystems such as control and protectionmechanisms, internal electrical systems and mechanical systems.
