TrAM H2020 Project has been nominated for the European Sustainable Energy Awards

We are very glad to share that the TrAM H2020 Project has been nominated for the European Sustainable Energy Awards 2023!
The TrAM Catamaran Medstraum is not only fully electric, zero-emission, fast, buy also highly efficient in terms of hydrodynamic performance, which has been essential for such a battery-driven fast ferry concept being feasible and finally built and in operation! #HSVA is happy to make a substantial contribution to this great project.

The winner will be decided by the public - we would be happy if you voted for this great project!

We are glad to give you a small insight into a current project in our large towing tank!

At the moment we are conducting model tests for Baltic Workboats Ltd testing the new patrol boats for Flotte Hamburg GmbH & Co. KG intended for the Hamburg’s water police. The seakeeping tests will demonstrate how the ship behaves in the rough environment of the North Sea and give insights in how the conditions will be like for the crew on board. The test campaign will be completed by resistance and propulsion tests, ensuring the efficiency and effectiveness of the ships!

Models are built from sustainable flax fibre delievered by greenboats.


Thanks for the visit at HSVA!

We had the pleasure of welcoming MPC CONTAINER SHIPS, MPC Capital and their partners North Sea Container Line and Elkem ASA for the seakeeping tests for their new 1,300 TEU container vessels in our Large Towing Tank. The tests were successfully conducted under the gaze of numerous spectators. The vessels are dual-fuel methanol newbuildings that, according to MPC CONTAINER SHIPS are "[…] taking a significant leap forward in [their] commitment to using carbon neutral solutions in intra-regional container trades, together with strong partners."

Thank you for a great afternoon with interesting discussions, we are already looking forward to seeing you here again in the near future!

Towards a lower-emission shipping future with wind propulsion systems

Shipping contributes substantially to global greenhouse gas emissions. Efforts to reduce these emissions are being made everywhere at many levels, with sail (auxiliary) propulsion systems in particular experiencing a renaissance. As part of its maritime research program, the German Federal Ministry of Economics and Climate Protection is now for the first time funding a project to optimise additional wind propulsion systems on board merchant ships, specifically Flettner rotors. On the basis of numerical and experimental models, the new FlettnerFLEET project is developing largely improved design principles for the integration of additional wind propulsion in modern merchant ships, both for newbulidings as well as retrofits. In addition, the design and operation of the rotors are also being optimised. Within the framework of the joint project led by MARIKO GmbH, HSVA will carry out the aero- and hydrodynamic investigations and developments for optimised wind ships and thus further establish the topic of wind propulsion as a new mainstay at HSVA. Detailed information on the FlettnerFLEET project can be found in the press release, e.g. at Greenshipping-Niedersachsen or Hansa-Online.


The HSVA team sends many greetings for the "International Day of Women and Girls in Science"!

On this special day, we would like to encourage young women to apply for studies or apprenticeships, also in the technical field. Our work is always exciting and diverse, not to forget creative! So every day we are busy finding new solutions to constantly changing problems and developing the shipping industry further.

Friedrich Mewis and Dirk Lehmann win the German Environmental Award 2022!

The engineers Friedrich Mewis and Dirk Lehmann have won the German Environmental Award 2022 with their invention of the power-saving Becker Mewis Duct® (BMD), developed to make a significant contribution to environmental protection in maritime shipping.

We sincerely felicitate our former colleague Friedrich Mewis, who used to be head of the "Resistance and Propulsion" department at HSVA for ten years, as well as Dirk Lehmann, BMS Managing Director, on this great success. Congratulations – well deserved!

HSVA is proud to have been a development partner to test the BMD in its beginning and we would like to take this opportunity to thank Becker Marine Systems GmbH for the great cooperation over all the past years – we are looking forward to further projects in the future!

Show Day: HSVA & GTT (Gaztransport & Technigaz)

As part of the 30th SMM Hamburg, we had the great opportunity to open the doors of HSVA together with our partner GTT (Gaztransport & Technigaz). With pleasure we could demonstrate our interested guests the concept of the ballast water-free LNG tanker, which was developed by GTT, equipped with an Anti-Roll Tank by Hoppe Marine GmbH and a propulsion system by SCHOTTEL Industries GmbH, hull lines tested and optimized at HSVA. Moreover we provided an insight into our testing facilities and used the time for interesting discussions and conversations.


MS Medstraum

MS Medstraum, the world’s first fully electric and zero-emission fast ferry, has arrived at her home port Stavanger and is ready for operation - congratulations!

Polar Research Vessels

Rapid change in climate conditions and marine traffic require the development of versatile vessels to support research, monitoring, safeguarding and environmental protection tasks in polar waters.

HSVA Recommends

A very good read for those interested in ship safety, damage stability and numerical modeling was just published in Applied Ocean Research.
