IEC 61400-3-1:20 19概述了固定式海上风力涡轮机的最低设计要求，并不打算用作完整的设计规范或说明手册。 几个不同的方可能负责承担海上风力涡轮机的设计、制造、组装、安装、架设、调试、操作和维护的各种要素，并确保满足本文件的要求。这些方之间的责任划分是合同事项，不在本文件的范围内。 本版取消并取代2009年出版的IEC 61400-3第一版。与IEC 61400-3第一版相比，该版本包括以下重大技术变更: a)对设计载荷表进行了修订，以简化波浪方法，既适用于正常海况的几种阵风情况，也适用于极端海况的一些情况。负荷计算指南已相应更改； c)对于负载安全系数，现在直接参考IEC 61400-1； d)控制系统已与IEC 61400-1中的最新更新保持一致； e)波谱已被ISO 19901-1的参考所取代； f)修订和更新了关于冰块装载的附件 g)介绍了两个关于热带气旋的资料附件 h)文本的其他部分已与IEC 61400-1保持一致

IEC 61400-3-1:2019 outlines the minimum design requirements for fixed offshore wind turbines and is not intended for use as a complete design specification or instruction manual.
Several different parties may be responsible for undertaking the various elements of the design, manufacture, assembly, installation, erection, commissioning, operation and maintenance of an offshore wind turbine and for ensuring that the requirements of this document are met. The division of responsibility between these parties is a contractual matter and is outside the scope of this document.
This edition cancels and replaces the first edition of IEC 61400-3 published in 2009. This edition includes the following significant technical changes with respect to the first edition of IEC 61400-3:
a) The design load table has been revised to simplify the approach to waves, both for several gust cases with the Normal Sea State, and for a number of cases with the Extreme Sea State. The guidance for load calculations has been altered accordingly;
c) For load safety factors reference is now made directly to IEC 61400-1;
d) Control system has been aligned with the latest updates in IEC 61400-1;
e) Wave spectra has been replaced by a reference to ISO 19901-1;
f) The annex on ice loading has been revised and updated
g) Two informative annexes concerning tropical cyclones have been introduced
h) Other parts of the text have been aligned with IEC 61400-1
