What is PD IEC TS 61400‑3‑2 about?

PD IEC TS 61400‑3‑2 is the second part of a multi-series standard. It gives details about wind energy generation systems.

PD IEC TS 61400‑3‑2 is a technical specification that 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.

PD IEC TS 61400‑3‑2 covers the following types of floating substructures that are explicitly considered within its context:

Ship-shaped structures and barges
Semi-submersibles (Semi)
Spar buoys (Spar)
Tension-leg platforms/buoys (TLP / TLB)

Note 1: PD IEC TS 61400‑3‑2 outlines minimum design requirements for floating offshore wind turbines (FOWT) and is not intended for use as a complete design specification or instruction manual.

Note 2: PD IEC TS 61400‑3‑2 is applicable to unmanned floating structures with one single horizontal axis turbine.

Who is PD IEC TS 61400‑3‑2 for?

PD IEC TS 61400‑3‑2 on requirements for floating offshore wind turbines is for:

Authority dealing with wind energy generation system
Companies manufacturing wind turbines
Entities dealing with installation, erection, commissioning of wind turbines
Construction and design engineers
Wind energy project managers

Why should you use PD IEC TS 61400‑3‑2?

Wind turbines use clean, cost-efficient, and sustainable form of energy, i. e. wind to generate electricity. The wind industry onboarded a very ambitious venture recently, i.e. placing turbines on floating platforms in the water, instead of fixed foundations.

PD IEC TS 61400‑3‑2 focuses on the engineering integrity of the structural components of a floating offshore wind turbine (FOWT). It is also concerned with FOWT’s 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 floatability and a station-keeping system.

PD IEC TS 61400‑3‑2 gives you the various elements of the design and provides you with an appropriate level of protection against damage from all hazards during the planned lifetime ensuring the quality and safety of FOWT’s substructure.
