適用范圍：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.A wind turbine shall be considered as an offshore wind turbine if the support structure issubject to hydrodynamic loading. The design requirements specified in this standard are notnecessarily sufficient to ensure the engineering integrity of floating offshore wind turbines.This standard should be used together with the appropriate IEC and ISO standards mentionedin Clause 2. In particular, this standard is fully consistent with the requirements of IEC 61400-1. The safety level of the offshore wind turbine designed according to this standard shall be ator exceed the level inherent in IEC 61400-1. In some clauses, where a comprehensivestatement of requirements aids clarity, replication of text from IEC 61400-1 is included.
