So, how is the transportation of wind turbines carried out?
This transportation must be governed by special permits since we are talking about special trucks and we must permission must be requested to the traffic authorities.In the case of blade transport, a special permit must be requested since their length exceeds 16 metres as stated in the General Vehicle Regulations.In order to drive on the road, these permits must be requested in order to guarantee at all times the road safety and avoid damage to infrastructure that could be caused by poor organization on the route or possible dangers for road users. The three types of authorization are:Generic authorization
It is used for vehicles with a maximum length of 20.55 m x 3 m wide x 4.5 m high. The weight cannot be greater than 45 tons.Special authorization
For vehicles whose length increases by 4 meters compared to the generic authorization. Their weight cannot be greater than 100 tons.Exceptional authorization
Máximo 5 m de ancho x 4.5 m de alto.La longitud y el peso es la misma que la special authorization..To apply for this type of authorisation from the competent traffic authorities, an itinerary must be established with origin and destination (points A and B), always identifying the routes to be used and the provinces through which the transport will travel.The competent authorities will always choose the most direct and consistent route to complete the journey.Request your quote in under 3 minutes — just one click.Frequently Asked Questions about Wind Turbine Transport
Why does wind turbine transport require a specialist fleet and cannot use a standard trailer?
Wind turbine components exceed all legal dimensions: blade 70-90 m long (standard trailer 13.6 m), tower 5 m diameter (standard road 2.55 m), nacelle 70-100t (standard 24t). They require: 1) Specialist vehicles — blade lifters (blades), modular self-loaders (towers), extra-heavy low-loaders (nacelles). 2) DGT special permits for every section. 3) Pilot vehicle and sometimes Guardia Civil escort. 4) Adapted routes avoiding narrow roundabouts, tunnels, bridges. A niche service with very few operators in Spain.
How much does it cost and how long does it take to transport a complete wind turbine from port to wind farm?
Cost per turbine (3 blades + 1 tower + 1 nacelle), 200-400 km section from Bilbao/Valencia/Cádiz port to inland Spain wind farm: €25,000-45,000 depending on terrain. Lead time: 5-10 days per complete turbine (the blade lifter vehicle only moves in daylight with section-by-section permits). For wind farms with 30-50 turbines, the logistics plan is a project in itself (3-6 months). Coordinate with the agency 6 months ahead.
What special regulations govern wind turbine transport in Spain?
Four regulatory frameworks: 1) General Vehicle Regulation (RD 2822/1998) — maximum vehicle plus load dimensions. 2) Complementary Circulation Authorisation (Order FOM/1230/2013) — section-by-section permit. 3) Route viability studies (bridges, tunnels, clearances) — mandatory before transport. 4) Notification to Guardia Civil and town councils along the route. Without these permits, fines of €6,000-30,000 plus transport impound.
Who bears the risk and liability if a blade is damaged during specialist transport?
Liability is split contractually: 1) Shipper (OEM manufacturer): guarantee proper packaging and loading at port. 2) Carrier: liable during the trip under the LCTTM, extended by declared value (blades worth €200,000-500,000). 3) Wind farm developer: liable for unloading and receipt at the farm. Standard CMR insurance is insufficient — you need all-risk insurance with specific declared value. Insurance cost: 0.3-0.8% of value.
How do I coordinate the logistics of a 50-turbine wind farm with installation deadlines?
Three keys: 1) Origin-destination synchronization: wind turbines arrive at port in batches; The park has limited storage capacity (5-8 pre-installed units). Time between port-park-installation critical. 2) Weather window: installation only possible with wind <8 m/s — coordinar transporte con previsión meteorológica del parque. 3) Disponibilidad grúa pesada (típicamente 1-2 grúas para 50 turbinas) determina velocidad de instalación. La logística debe alinearse con esto.
