Hydro-Acoustic Measurements in HYKAT
In the HSVA archive we found this nice picture showing a ship model in the HYKAT (Hydrodynamic and cavitation tunnel) with the (illuminated) acoustic chamber below the measuring section. The HYKAT of HSVA has especially been designed with focus on its hydro-acoustic abilities. Due to its very low self-noise level - around 20dB lower than standard cavitation tunnels – it offers best conditions to measure propeller radiated noise. The results give foresight of the real ship’s and offshore structure’s underwater noise level.

HSVA has been contracted by The Norwegian Ship Design Company
HSVA has been contracted by The Norwegian Ship Design Company (TNSDC) to optimize their all zero-emission self-discharging hydrogen-fuelled bulk carrier "With Orca" of Norwegian ship owner Egil Ulvan Rederi AS. The project was recently awarded with the Approval in Principal (AiP) by Lloyd's Register following a highly detailed hazard identifcation (HAZID). HSVA will support TNSDC with the hydrodynamic design of the vessel.
"This project is a milestone in using hydrogen at sea and combining the power of wind to drive the ship", says HSVA project manager Peter Horn.
Global Recycling Day 2022
Just in time for the Global Recycling Day 2022, HSVA is launching a project to process 50 kg of polylactide waste from HSVA's 3D printing center into new filament.
Besides being a renewable raw material, PLA is also useful for recycling economy.
Recycling economy saves time, energy and resources. It reduces the volume of waste and enables "zero-waste" production in the ideal case.
The aim of this project is to test the extent to which recycled PLA filament is suitable for production in HSVA.
On our YouTube channel you will soon learn how recyclable waste becomes a final product!
We are very happy to present you our new YouTube channel!
Dive into the world of ship model tests at HSVA and learn regularly about our work, projects and of course our testing facilities.

Reduction of Required Minimum Engine Power to Receive Baltic Ice Class
Did you know that there are possibilities to reduce the minimum engine power required for ice class approval? It is possible to receive an Ice Class (IA, IB or IC) approval based on brash ice model tests in HSVA’s large ice model basin. For single cases (ship types) even a pure theoretic brash ice performance prediction based on direct propulsion calculation and resistance formula can be already regarded as sufficient by reviewing authorities. The reduction in power compared to a standard rules calculation is on average between 20 and 50 %. For further information and consultation, please contact us at email@example.com or firstname.lastname@example.org.
HSVA studies prove Medstraum’s unique efficiency

HSVA is supporting a DFG study on nonlinear wave-ice interaction with another test series in the large ice model basin
„[…] It has been shown theoretically that nonlinear effects can be triggered and intensified by solid ice as decreasing wave lengths under such ice condition result in the steepening of the waves.
In order to shed more light onto these occurrences, a research project funded by the German Research Foundation (DFG, project 407532845) has started to show numerically and experimentally that nonlinear wave-ice interaction can take place under solid ice, explaining ice-breakup processes far away from the ice edge. The small-scale experiments are conducted at the large ice basin of the Hamburg Ship Model Test Basin (HSVA), where wave properties are measured before entering the ice sheet and during their progression through the ice sheet. […]“

HSVA signs IWSA‘s open letter aiming at advancing the decarbonization of the shipping industry
Together with more than 90 maritime companies, HSVA has signed an open letter demanding decision-makers in the maritime industry, as well as the entire shipping community, to re-evaluate and utilize all energy solutions. Strategic integration of wind propulsion systems is expected to achieve essential reductions in carbon emissions and make a significant contribution for reaching emissions targets by 2050.
To seriously integrate the power of wind propulsion into the fight against climate change, the letter calls for the establishment of a multi-stakeholder working group to assess and quantify the potential of wind propulsion. It requests for launching a comprehensive strategic review of current efforts to decarbonize the shipping industry in light of the climate crisis, as well as ensuring that a level playing field is created and maintained for all propulsion systems. The current approach, which currently focuses on fuels, needs to be overcome.

Conference article „Experimental investigations on the level ice resistance of ships with non-typical icebreaking bow shapes“ chosen for publication in the International Journal of Ships and Offshore Structures (SaOS)
For non-typical icebreaking ships with high stem and/or small waterline angles, the hull–ice interaction process in level ice comprises a combination of many different phenomena which is difficult to be described by existing straightforward approaches. In order to gain knowledge about the level ice resistance of ships with non-typical icebreaking bow shapes, a methodology to improve the principal understanding of the hull–ice interaction process, ice failure, level ice resistance and its distribution along the ship hull during model scale ice tests is developed. For this purpose, one ship model (Figure 1) has been manufactured and extensively instrumented. By performing resistance tests at several loading conditions, in model ice sheets of different thickness and at multiple speed values, relevant information on the nature of ice resistance of such ship type can be obtained (Figure 2). In this paper, the methodology is briefly summarized and part of the results of the model testing campaign are presented and discussed.
The full length paper (not free of charge) can be found at
The presentation belonging to the conference paper can be downloaded (free of charge) at

HSVA starts the new year with a tailwind - new corporate structure and changes in the management team
HSVA is giving itself a new, customer-oriented structure, which is now based on its main product groups. The technical expertise will be divided into three major areas: "Ships", "Offshore" and "Arctic Technology".
All HSVA employees are organized into pools, which provide the individual specialist teams with the resources they need. Inspired by agile working methods, these teams work independently on both customer orders and R&D projects. Project managers serve the customers as single point of contact to provide competent and holistic consulting. HSVA expects this to improve their customer service as well as to enable fast and flexible action on requirements and trends of the markets.
HSVA is also reorganizing its management team around Managing Director Prof. Dr. Janou Hennig:
Dr. Florian Kluwe is responsible for the "Ships" division.
The "Offshore" division will be represented by Dr. Christian Schmittner.
Nils Reimer is responsible for the "Arctic Technology" division.
Holistic technologies for the energy management of ships
Together with leading partners from the maritime industry, HSVA is launching a large-scale project to develop an energy management system for ships based on rational methods. Partners are Hamburgische Schiffbau-Versuchsanstalt GmbH, AVL Deutschland GmbH, Entwicklungszentrum für Schiffstechnik und Transportsysteme e.V., Friendship Systems AG, Technische Universität Berlin, Technische Universität Hamburg, 52°North - Initiative for Geospatial Open Source Software GmbH, Universität zu Lübeck, Maritimes Zentrum der Hochschule Flensburg, C. Büttner Shipmanagement and AVL Software & Functions. Together with further associated ship operators , a forward-looking energy management and decision support system will be developed, taking into account current operational data and geo-information. This will contribute to improving energy efficiency and reducing emissions from shipping.
The energy consumption of merchant ships is largely determined by their hydrodynamic properties and the systems on board. In some cases, up to 90% of primary energy consumption is used for propulsion and must therefore be optimally managed. The aim of MariData is to develop, improve and classify rational modules for ship energy management by using a carefully selected combination of state-of-the-art maritime technologies and experience as well as AI-based tools and methods for a pioneering product for holistic ship energy and operations management.
Together with geo-information and a Decision Support System (DSS) that brings together technical, environmental and economic data, energy consumption information will be integrated into a platform that can be used both on board the ship and shore-side by a shipping company. The platform will provide on-line simulations for decision support to ship management, as well as assistance with short, medium and long-term forecasts and decisions related to ship operation.
MariData's innovations lie in the precise determination and analysis of the current ship's drag, propulsion and respective fuel consumption under realistic operating conditions, taking into account wind and wave influences. On this basis, a rational analysis of the influences of the individual components is carried out, thus improving the quality of the forecast and the basis for navigation decisions. Integration with state-of-the-art geoservices takes the planned system to a new level. In addition, there are flexible approaches to quickly generate missing data (e.g. geometry) and integrate it into the analysis.
The project is funded by the German Federal Ministry for Economic Affairs and Energy.

The overall goal of the project is to minimise fuel consumption, improve manoeuvring abilities and increase navigational safety by introducing three high-efficiency innovations to Ultra Large Container Ships (ULCS): twin propeller configuration, pod propulsors and contra rotating propellers concept. The project will be realized during a three-year period, starting from September 1, 2020. Within the project, HSVA will enhance the comparative propulsion testing method in HYKAT to assess unconventional arrangements like the twin-crp-pod or others. This will expand HSVA’s service portfolio. More details including all partners can be found in the coming NewsWave. This project is funded by the German Federal Ministry for Economic Affairs and Energy (reference number 03SX520A).
Dr. Daniela Myland awarded at OMAE 2020
Deputy Head of Department Arctic Technology Dr. Daniela Myland received the Subrata Chakrabarti Young Professional Award for her outstanding publication on “Experimental and theoretical investigations on the characteristics of ice floes broken by ships sailing ahead in level ice”, presented at OMAE 2019 in Glasgow, Scotland. This award, named in commemoration of Dr. Chakrabarti, is an all-conference award given to a young professional, which recognizes both the originality and technical merit of the paper and the delivery of the presentation.
In particular, the paper investigates correlations between ice floe characteristics, hull shape parameters, ice properties and the ice resistance. Therefore, systematic model tests in level ice and pre-sawn ice with different icebreaking ship models of one ship type have been conducted. During the tests in level ice under water video records have been taken from below the ship model. Video frames have been analyzed by application of a dedicated image analysis procedure which is mainly based on a number of semi-automatic scripts applied in Matlab®. Results of the analysis are presented and discussed within this paper.

HSVA Opens Centre for Additive Manufacturing
When you enter the room, stepper motors hum and print heads rush over half-finished components. Since the beginning of 2020, three different printers have been producing appendices, superstructures and an entire ship model. By using different printing processes, the high expectations of our customers regarding geometry and accuracy are always met perfectly.
The first 3D-printed model for use in a seakeeping campaign was successfully tested. The model had a length of 2.35 m and an integrated roll tank, equipped with realistic construction details inside. This model including superstructures was made of PLA and proved its performance in tests under extreme conditions, even leading to capsizing of the vessel.
No matter how complex the geometry may be, HSVA produces your model at the pulse of time.

HSVA goes new green ways in model manufacture and investigates ship safety in EU-project FLARE
The construction of the model of a damaged RoPaX ship for the EU research project FLARE (Flooding Accident Response) has started in HSVA.
Thin walled ship shell for ship damage stability tests.
The thin walled ship shell needed for damage stability studies, in which some internal compartments will be flooded, is manufactured of a new sustainable Natural Fiber Composite (NFC) instead of the classical Glass Fiber Reinforced Plastic (GFRP/GFK) often used in such models. The new material is more environ-mentally friendly in its production and disposal than classical GFRP, and is based on the use of natural fibers as reinforcement instead of the relatively heavy glass or expensive carbon. Also the ready-made ship shell is easier to cut and more pleasant to work with during the outfitting of the model in this case with the damage openings on the hull.
Raking damage at the bilge.
In the first phase of the coming model tests roll damping coefficients of damaged ships will be determined for use in numerical simulations of ship survival in seaways. Two damage shapes in different sizes will be tested: A raking damage at the ship bilge due to accidental contact with a rock, like the one that sank the MV Costa Concordia, and a typical collision damage at the ship side as a result of a perpendicular collision too often seen in busy fairways having frequent crossing ferry traffic.
Collision damage at ship side.
Collision damage penetration at ship interior.
Further benchmark tests will follow. The 3D- printed parts of the model will be changed with relative ease to other ones as required by the test plan.
The use of sustainable raw materials, traditional wood, polylactic acid (PLA) made of corn starch and used in 3D-printing, bio-based epoxy resin and flax fiber in NFC models, allows the HSVA to manufacture composite models almost solely of sustainable materials, thus also reducing the carbon footprint about 70 per cent in comparison with a corresponding GFRP model.
The German National R&D project AERONAUT (www.aeronaut-project.eu) has successfully installed the prototype wind deflecting spoilers on board our operator partner's Jüngerhans vessel Pictor J. We are looking forward to operational data and experiences using this novel aerodynamic improvement and energy saving device.

HSVA as part of MOSAiC - the biggest arctic expedition of all times!
In fall 2019 the biggest arctic expedition of all times – the MOSAiC Expedition1 led by the Alfred-Wegener-Institut2 - has started: Polarstern left Tromsø harbour to travel towards north, where it is frozen into the ice now for about one year drifting across the Arctic along with the natural ice drift. This is a high-tech repetition of the famous Fram Expedition 1893-1896. While Fridtjof Nansen’s original intention was to reach the North Pole, this expedition’s scope is to record interdisciplinary data during an entire annual cycle including the arctic winter. The data shall serve mankind to understand this sensitive region, also with respect to climate change. These days 20 nations, abt. 600 people on board and further 300 people at home are involved in this expedition. HSVA’s role in MOSAiC is to measure lateral ice pressure in the vicinity of Polarstern and to monitor the resulting loads on the vessel itself. Therefore, HSVA had contracted the Hamburg University of Technology to install strain gauges and temperature sensors on the steel structure of the vessel. Partners from Europe, USA and Asia install and maintain ice pressure panels in the ice on behalf of HSVA. The recorded data is expected to give insight in lateral ice pressure in the vicinity of structures, but it is also to be understood as the basis for all kinds of generic ice studies. HSVA’s work within MOSAiC is funded by the German Federal Ministry for Economic Affairs and Energy (reference number 03SX365A).

HSVA proudly congratulates its employee Daniela Myland for achieving her PhD degree!
Congratulations to Daniela Myland, Deputy Head of Arctic Technology Department, for achieving her PhD degree at NTNU with her thesis on “Experimental and Theoretical Investigations on the Ship Resistance in Level Ice”. The thesis focused on the resistance of icebreaking ships advancing continuously in level ice, whereby different aspects of the ice resistance were analysed on the basis of ice model tests. Newly developed methods and techniques were used in the course of the model tests and a semi-empirical resistance prediction method was improved with the gained insight. The work allows an enhanced analysis of the ice breaking process in model and full scale and can be seen as a basis for a refined ice resistance prediction in the future.
