About Hydrautrans
Specialist in Drive Trains
Hydrautrans is a wind turbine development company specialized in Drive Train solutions. We develop a dedicated +12 MW mechanical-hydraulic drive train solution, fit for the next generation of offshore windfarms.
Our vision
At Hydrautrans, we believe in innovation by combining existing proven technologies into a realistic, competitive product. The outside of the box approach in the design of the Hydrautrans Drive Train concept is the core driver of our colleagues and partners. Therefore, Hydrautrans is a unique group where traditional status-quo is challenged and questioned. We envision a next generation Drive Train to lower the cost of offshore wind and thus, the Levelized Cost of Energy (LCoE) for the society.
Our mission
Hydrautrans strives to contribute to cost reduction in the offshore wind market, by developing an innovative drive train by combining existing proven technologies.
Technology
- Big direct driven generators increase exponential in weight.
- High or medium speed generators also increase exponential in weight.
- Increase of top weight leads to higher installation crane capacity which complicates the transport logistics and installation.
- Gearboxes and related auxiliary systems have a high failure rate and a high maintenance need.
The core of the Hydrautrans Drive Train concept:
Weight reduction
Installation solution
Modular design

In memoriam Bart van Neerbos
Op 25 maart 2020 is Bart van Neerbos, oprichter, uitvinder, directeur en inspirator van Hydrautrans overleden.
Op 28 maart plaatste Hydrautrans onderstaande rouwadvertentietekst in NRC.
Bart was ondernemend, charmant en gedreven tot op het laatst. We gaan hem missen.
Team en aandeelhouders van Hydrautrans
Het voelt vreemd om verder te gaan zonder Bart en we missen de onvermoeibare energie die hij ondanks zijn hoge leeftijd bleef uitstralen. Ik, als zijn ‘jongere’ collega/partner?, kon regelmatig rekenen op aanwijzingen en op aanmoediging om achter financiers, partners, subsidies, klanten enz. aan te gaan. Hij tackelde financiële uitdagingen kundig en bedacht voortdurende nieuwe concepten. Een nieuwe installatiemethode met een innovatieve kraan voegde recent opnieuw waarde toe aan Hydrautrans. Op reis naar onze contacten kon ik genieten van zijn rijke ervaring en van verhalen over zijn jonge leven in Schiedam als we daar bij potentiële partners op bezoek gingen of over de vele bedrijven die hij heeft opgezet of als manager heeft gereorganiseerd tot verhalen over het begin van de DarwinD turbine die nu in grote aantallen in China draait. Vlak voor het zetten van een beslissende stap van Hydrautrans is Bart nu heengegaan.
Het zou mooi zijn om ooit onder een windturbine met een Hydrautrans Drive Train te staan en het glas te heffen op deze kleurrijke man.

A new hydraulic powertrain may pave the way for reliable and economical wind turbines.
Offshore wind electricity generation has seen annual growth above 25% in recent years, as global consumers increasingly embrace renewable energy. The U.S. National Renewable Energy Laboratory predicts accelerated market growth in the next decade, with cumulative capacity rising to nearly 200 GW by 2030 and over 500 GW by 2050.
To help reach these ambitious goals, wind-turbine specialist Hydrautrans BV, based in Utrecht, The Netherlands, is looking to tap the proven benefits of hydraulics. It is developing a 12+ MW mechanical-hydraulic drive train that is said to be ideally suited for next-generation offshore windfarms.

Hydrautrans is developing a hybrid mechanical-hydraulic drive train for 13+ MW offshore wind turbines. The hybrid drive train has a modular design and is currently designed with a capacity of 13MW and can be up scaled to higher capacities.
The Hydrautrans Drive Train (HDT) makes use of the patented Floating Cup Technology of INNAS. Hydrautrans and INNAS performed the cup and piston test, in collaboration with TNO and VDL ETG precision. The cup and piston tests were conducted to ensure the manufacturability of the cup and plunger for the HDT and validated the use and efficiency of the Floating Cup Technology in the HDT. The results, reported by Hydrautrans, of the tests showed an efficiency of around 99% and the absence of wear and tear. Further VDL achieved a very high precision in the manufacturing process. The measurements carried out by INNAS also showed low resistance. The hydraulic components have a high-power density which enables a compacter and lighter drive train compared direct drive turbines. The company is now looking for a wind turbine manufacturer to implement the HDT technology.

Drive trains are heavy components of wind turbines with high maintenance requirements. More reliable or lighter solutions can be direct drive generators, medium speed generators in combination with gearboxes with a lower gear ratio or the application of a lighter, more reliable gearbox. The Hydrautrans Drive Train potentially provides such a lighter and more reliable gearbox. In an earlier project the required pump and motor and the complete drive train: the Hydrautrans Drive Train (HDT) have been designed and conceptually engineered.
