Wind turbines - Part 3: Design requirements for offshore wind turbines
IEC 61400-3:2009 specifies additional requirements for assessment of the external conditions at an offshore wind turbine site and specifies essential design requirements to ensure the engineering integrity of offshore wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime. Focuses on the engineering integrity of the structural components of an offshore wind turbine but is also concerned with subsystems such as control and protection mechanisms, internal electrical systems and mechanical systems. It should be used together with the appropriate IEC and ISO standards, in particular with IEC 61400-1. This publication is to be read in conjunction with IEC 61400-1:2005.

Eoliennes - Partie 3: Exigences de conception des éoliennes en pleine mer
La CEI 61400-3:2009 spécifie des exigences complémentaires d'évaluation des conditions externes sur un site d'éoliennes en pleine mer ainsi que les exigences essentielles de conception, afin d'assurer l'intégrité technique de ces dernières. Elle a pour objet de fournir un niveau de protection approprié contre les dommages causés par tous les risques pendant la durée de vie prévue. Se focalise sur l'intégrité technique des composants structurels d'une éolienne en pleine mer, mais concerne également les sous-systèmes, tels que les mécanismes de commande et de protection, les systèmes électriques internes et les systèmes mécaniques. Il convient d'utiliser la présente norme avec les normes CEI et ISO appropriées, en particulier avec la CEI 61400-1. Cette publication doit être lue conjointement avec la CE I 61400-1:2005.
Vetrne turbine - 3. del: Zahteve za načrtovanje vetrnih turbin na morju (IEC 61400-3:2009)
Ta del IEC 61400 opredeljuje dodatne zahteve za ocenjevanje zunanjih okoliščin na območju vetrnih turbin na morju ter hkrati opredeljuje bistvene zahteve za načrtovanje, z namenom zagotoviti integriteto inženirstva vetrnih turbin na morju. Njegov namen je določiti primerno raven zaščite pred škodo, ki bi jo lahko povzročile vse nevarnosti med načrtovano življenjsko dobo. Ta standard se osredotoča na integriteto inženirstva strukturnih komponent vetrnih turbin na morju, vendar se ukvarja tudi s podsistemi, kot so mehanizmi nadzora in zaščite, notranji električni sistemi in mehanski sistemi. Vetrna turbina se šteje kot vetrna turbina na morju, če je nosilna konstrukcija podvržena hidrodinamični obremenitvi. Zahteve za načrtovanje, opredeljene v tem standardu, niso nujno zadostne za zagotovitev integritete inženirstva plavajočih vetrnih turbin na morju. Ta standard se mora uporabljati skupaj s primernimi IEC in ISO standardi, omenjenimi v Klavzuli 2. Zlasti je ta standard popolnoma skladen z zahtevami IEC 61400-1. Raven varnosti vetrne turbine na morju, načrtovane v skladu s tem standardom, bo na ravni iz IEC 61400-1 ali jo bo presegala. V nekaterih klavzulah, kjer izčrpna izjava o zahtevah pomaga pri jasnosti, je vključena kopija besedila iz IEC 61400-1.
