What is Lorem Ipsum?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Where does it come from?

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32.

“HWS was invited by VATTENFALL to Amsterdam Headquarters, thanks to the EU EIC event”

May 24th, Amsterdam, The Netherlands.

Mariano Abadia and Erik van der Woude presenting the work of HWS Concrete Towers (www.hwstowers.com) to VATTENFALL (https://lnkd.in/dCEYGiHK), at the event organized by the EU-EIC (https://lnkd.in/d5Z382N6).



• One week ago we had the opportunity to introduce the products that the HWS’ team has been developing in the world of precast/prestressed concrete structures for over ∼45 years.
• Specifically the bridges made of MODULAR parts joined by the simple and efficient AirJOINT/BSST (∑ Parts + Joints = “LEGO concept”), solutions in which we see high applicability to future offshore wind energy installations.
• It was a pleasure to show this work to a very interested and highly qualified team.

More information and examples about this type of innovative (but not recent) bridge solutions:

“HWS will attend WindEnergy 2023 (Booth C2-A10), in Copenhagen DK, April 25th to 27 th” (HWS)

Looking forward to seeing you all at WindEnergy 2023, in Copenhagen DK, April 25th to 27 th!

Please feel free tu visit us on the HALL C2 – BOOTH A10, as part of the “Wind Energy Basque Country” group.

If you want to know a bit more about AirCLIMBER self-climbing crane, precast/prestressed concrete AirTOWERs up to 220 m Hub Height, the  AirBASE precast foundations and other HWS CONCRETE TOWERS’ projects in which we are working on all over the world, please do not hesitate in contacting directly to arrange a meeting:

We will be glad to assist you.


“The HWS-AirBASE—a precast foundation for Wind Turbines: an TRUE INNOVATION in the wind Energy Sector” (HWS)

If you are looking for a TRUE INNOVATION, ….please think in HWS-AirBASE — a precast foundation for Wind Turbines:

It is the only true innovation in the field—since the P&H concept (USA, 1994)—because it is also a completely new structural scheme, which introduces multiple advantages: 

  • Up to 35% COST reduction, depending on the WTG-Model (hub height, tower material, rotor diameter and power rated, which means more weight on top of the tower) and SOIL characteristics.
  • Up to 50% MATERIALS reduction (steel and concrete), while avoiding technical issues and long working time  associated to assembly up to 100-150 t of rebar and pouring 700-1.000 m3 of concrete.
  • Up to 50% CO2 EMISSIONS reduction, which is directly the amount of materials reduction,  since transport and labour represent less than 10% of those emissions.

Several structural and geotechnical advantages: 

  • The load transfer to the soil is much more efficient:  in fact it is regular, improving any “gapping” issues.
  • Being a cross of bridge-girders,  with only a small increase of length you will be able to resist much more momentum, which is the main load the Wind Turbine introduces, and must be resisted and transferred by the foundation.
  • Higher Stiffness, which is becoming an issue in the new WTG’ designs.

Being partially a precast parts, all advantages of precasting are obviously introduced: 

  • Use of more resistant concretes.
  • Better quality control.
  • Better timetable/schedule control.
  • Possibility  of longer lasting working time on the field in strong/rough weathers, both cold and hot.
  • Processes industrialization.
  • Serialization of the design foundation: it is possible to develop a catalogue of foundations for a particular WTG.

If you would like to know more about our project, we will be delighted to welcome you in our booth in n the WindEnergy Hamburg-DE fair, next September 27-30, Hall B2, booth B2.EG.410A.

Kindly reserve your  time slot so we will able to attend you better. Please do it writing to  jmsorazu@hwstowers.com

“CENER met the self-climbing AirCRANE demonstrator, March 18th” (HWS)

ENG: On 18 March, Mr. Pablo Ayesa, General Director, and Mr. Antonio Ugarte,  Director of the Wind Energy Department, both members of the CENER (Spain´s National Renewable Energy Centre, https://www.cener.com/en/) met, at the workshops of the company KEYTECH (www.keytech.es) located in Lecumberri (Navarre), the demonstrator of the self-climbing AirCRANE, development granted by the European Commission, under “Horizon 2020-SME Instrument”, No 804858 (Link to CORDIS: https://cordis.europa.eu/project/id/804858).
Also in attendance were Mr. Juanjo Etxalar and Mr. Telmo Sexmilo, representatives of CLAVE (https:/clave.capital) of Pamplona (Navarre), which manages the participation of the Basque industrial conglomerate MONDRAGON CORPORATION (https:/www.mondragon-corporation.com) in HWS, and that they will shortly expand its participation in HWS, together with INNVIERTE (https://www.cdti.es), to start the worldwide marketing of the developed solution.
In this way HWS Concrete Towers S.L. strengthens and guarantees its future.”
