标准范围

IEC TS 61400-3-2:20 19规定了评估浮动式海上风力涡轮机(FOWT)现场外部条件的附加要求，并规定了确保FOWTs工程完整性的基本设计要求。其目的是在计划寿命期间提供适当水平的保护，防止所有危险的损害。本文件侧重于FOWT结构部件的工程完整性，但也涉及子系统，如控制和保护机制、内部电气系统和机械系统。如果浮动下部结构受到流体动力载荷并由浮力和位置保持系统支撑，则风力涡轮机被认为是FOWT。FOWT包括五个主要子系统:RNA、塔、浮动子结构、站-保管系统和不属于RNA的机载机械、设备和系统。在本文档的上下文中明确考虑了以下类型的浮动子结构:a)船形结构和驳船，b)半潜式(semi)，c)翼梁浮标(spar)，d)张力腿平台/浮标(TLP/TLB)。除了上面列出的结构类型之外，本文件通常涵盖旨在支撑风力涡轮机的其他浮动平台。这些其他结构在几何形状和结构形式上可能具有很大的可变性，因此，本文件的要求只能部分涵盖这些结构。在其他情况下，本文件中规定的特定要求可能不适用于设计中的全部或部分结构。在所有上述情况下，符合本文件将要求设计基于其基础原则，并达到等同于或优于其中隐含水平的安全水平。本文件适用于具有一个水平轴涡轮机的无人浮动结构。对于单个浮动下部结构上的多涡轮机单元、垂直轴风力涡轮机或组合的风/波浪能系统，可能需要额外的考虑。本文件应与第2条中提到的适当的IEC和ISO标准一起使用。特别是，本文件旨在完全符合IEC 61400-1和IEC 61400-3-1的要求。根据本文件设计的FOWT的安全水平应达到或超过IEC 61400的固有水平？1和IEC 61400-3-1。

IEC TS 61400-3-2:2019 specifies additional requirements for assessment of the external conditions at a floating offshore wind turbine (FOWT) site and specifies essential design requirements to ensure the engineering integrity of FOWTs. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime.
This document focuses on the engineering integrity of the structural components of a FOWT but is also concerned with subsystems such as control and protection mechanisms, internal electrical systems and mechanical systems.
A wind turbine is considered as a FOWT if the floating substructure is subject to hydrodynamic loading and supported by buoyancy and a station-keeping system. A FOWT encompasses five principal subsystems: the RNA, the tower, the floating substructure, the station-keeping system and the on-board machinery, equipment and systems that are not part of the RNA.
The following types of floating substructures are explicitly considered within the context of this document:
a) ship-shaped structures and barges,
b) semi-submersibles (Semi),
c) spar buoys (Spar),
d) tension-leg platforms/buoys (TLP / TLB).
In addition to the structural types listed above, this document generally covers other floating platforms intended to support wind turbines. These other structures can have a great range of variability in geometry and structural forms and, therefore, can be only partly covered by the requirements of this document. In other cases, specific requirements stated in this document can be found not to apply to all or part of a structure under design. In all the above cases, conformity with this document will require that the design is based upon its underpinning principles and achieves a level of safety equivalent, or superior, to the level implicit in it.
This document is applicable to unmanned floating structures with one single horizontal axis turbine. Additional considerations might be needed for multi-turbine units on a single floating substructure, vertical-axis wind turbines, or combined wind/wave energy systems.
This document is to be used together with the appropriate IEC and ISO standards mentioned in Clause 2. In particular, this document is intended to be fully consistent with the requirements of IEC 61400-1 and IEC 61400-3-1. The safety level of the FOWT designed according to this document is to be at or exceed the level inherent in IEC 61400？1 and IEC 61400-3-1.
