About us

Vienna Model Basin was founded 1912 under the patronage of the Austrian K. u. K.-Navy. Back then Vienna Model Basin’s towing tank was the largest tank in the world.

For more than a century, the private and independent

Vienna Model Basoin has influenced and led

developments of testing technology, methods,

standardisation and numerical procedures to solve

complex problems.

Vienna Model Basin was founded 1912 under the patronage of the Austrian K. u. K.- Navy. Friedrich Gebers was appointed as director of the tank in autumn 1911 when he was already engaged in the design of the towing tank. The appointment of Gebers was a fortunate coincidence as he was very experienced in constructing and reconstructing towing tanks in Übigau and Berlin. Besides his drive and expertise Gebers was highly skilled in the design and construction of measurement devices and testing facilities. After the break down of the Austrian Hungarian Monarchy the model basin soon could gain international appreciation, especially by the development of measuring equipment as well as the design and outfitting of ship model basins. In March 1945 Vienna Model Basin was hit by a bomb, unable to continue with operation and therefore closed. Despite the desolate situation after World War II, particularly in Austria, former employees started to build up the towing tank in 1951 under the leadership of Dr. Leopold Kretschmer, who was already employed since 1926. In 1953 work could be resumed. The membership society Schiffbautechnische Versuchsanstalt in Wien installed a new board in 1961; in 1963 the European Revocery Program (ERP) funded a new office building and some technical devices. Ever since the model basin in Vienna has the ability to manufacture ship models from wood and paraffin up to a length of 10 m including all appendages and propellers in calm water and in sea state. Dr. Leopold Kretschmer retired in 1976. As the number of committee members of the membership society decreased the society was shut down and the company given to the employees of the model basin under the leadership of Prof. Dr. Gerhard Strasser. He is running the company called Schiffbautechnische Versuchsanstalt in Wien GmbH / Vienna Model Basin Ltd with his associate Dr. Clemens Strasser. Vienna Model Basin Ltd improved its facilities to state-of-the-art technologies and extended its field of operation by integrating a cavitation tank and a wind tunnel. Many of the simulations are carried out numerically but need to be validated with model tests. Though a site in Austria focusing on naval architecture has only limited interests in the shipping industry and due to the fact that there are a number of well-known modern and large model basins in Europe, Vienna Model Basin Ltd is still competing and more than ever in demand. This is certainly credit of the leadership and its employees who perform worldwide acknowledged excellent experiments of various kinds based on principles of Friedrich Gebers and the work of Leopold Kretschmer.

Services

Vienna Model Basin Ltd offers a complete range of services to the naval industry and research institutes. Our services incorporate a unique combination of model testing, simulation and full- scale measurements.

Consulting

Due to our long lasting expertise in the fields of hydrostatics and hydrodynamics for almost 100 years Vienna Model Basin Ltd provides advice in the optimisation of the design, performance and safety of any kind of vessel. For a successful achievement of objectives various tools are used depending on the client’s requirements.

Numerical Simulation

Numerical methods for the computation of fluid flow have reached a stage where they can be successfully applied to a wide range of fluid flow problems arising in the marine industry and related fields. CFD methods provide an excellent means to reduce time consumption at an early design stage and thus shorten overall time spent on a new design. Furthermore, CFD methods for the first time ever offer the possibility to include hydrodynamic analysis in a complex computer aided design environment comprising different kinds of CAX technologies.

Powering and Performance

Ship performance prediction is one of the standard procedures at Vienna Model Basin Ltd. High measuring accuracy and reproducibility of the measured data and many years of experience in the fields of hydrodynamic tests are the basic of high degree accuracy by the correlation of test results to full-scale measurements. Besides conventional routine tests VMB carries out a lot of additional investigations, like optimization of hull form, determination of manoeuvring and seakeeping characteristics including slamming damage, and arrangements of energy saving devices, tunnels and nozzles. Towing tests with fishing gear, life-saving appliances and sport boats are also a part of VMB´s offer.

Seakeeping

Scale model tests in both regular and irregular waves are carried out in Vienna Model Basin's towing tank (head and following sea). In the towing tank seakeeping tests (using free running and captured models) can be carried out in any wave direction. In addition to studies of ship motions, accelerations, and wave added resistance, investigations of slamming pressure, the presence of water on deck, and broaching can be performed. Predictions of full-scale ship motions can be based on scale model test results only, or carried out in combination with simulations. Studies of dynamically controlled motion damping appendages can be carried out using computer simulations or model tests.

Manoeuvring

Vienna Model Basin Ltd performs all kinds of manoeuvring studies including those required for checking compliance with IMO's regulations. Examples of such tests are turning, zigzag, crash stop, and reversed spiral tests. They can be carried out with a free sailing model in the towing tank, in deep as well as shallow water. Vienna Model Basin Ltd can give advice and test the effect of changing the rudder design, rudder type, and hull form in order to improve manoeuvring performance and course stability. This can be done for any kind of vessel including the water-jet and pod propelled types.

Ship Stability

Stability against capsizing in heavy seas is one of the most fundamental requirements considered by naval architects when designing a ship. The purpose of studying capsizing is to establish an understanding of ship behaviour in extreme seas and to relate this to the geometric and operational characteristics of the ship to achieve cost effective and safe operation. In an industry with progressively diminishing returns and an ever increasing emphasis on safety this objective is becoming ever more important. As a consequence, the research effort in this field over the last 15 years has expanded considerably, as indicated by the plethora of publications available in the literature and the large number of specialist international conferences, symposia and workshops which have been held. Therefore Vienna Model Basin Ltd carries out stability experiments of intact and damaged ships for research, validation of numerical codes and administrative authorities.

Wind

The wind tunnel is used for different kind of aerodynamic achievements which deal with the behaviour of ships above the waterline. In most cases this also affects the ship's hydrostatic and hydrodynamic characteristics. Therefore the detailed superstructure of ships is built in model scale.

Cavitation

The cavitation phenomena are the vaporization of the water due to a decrease of the local pressure. Cavitation contributes to noise, energy losses, destruction of surfaces (erosion), unsteady flows and vibrations - which adversely affect the performance of ships, underwater vehicles, hydraulic pumps and turbines. Our services span from performing detailed investigations for ship yards, ships owners and propeller manufacturers, answering questions which need a high content of research and development work. Our activities cover a wide range of services related to marine propulsors. Most important is the role of the propulsor - hull-appendages interaction. The activities of the department include propulsor design and analysis, cavitation predictions and its effects on the full scale ship behaviour in terms of noise and vibrations, extensive model testing and long term research work.

Sea Trial

Vienna Model Basin Ltd offers a range of full scale investigations as part of their services. These services cover speed-power trials in order to determine the ship performance in terms of speed, power and propeller revolutions under predescribed ship conditions, and thereby verifying the satisfactory attainment of the contractually stipulated ship’s speed and power and to provide the ship’s speed and power for the calculation of the Energy Efficiency Design Index (EEDI) as required by IMO. Furthermore, the manoeuvring characteristics as a reaction to rudder and engine actions can be obtained by full scale manoeuvring trials. The tests usually concern the inherent dynamic stability, coourse-keeping ability, initial turning/course-changing ability, yaw checking ability, turning ability and stopping ability.

Facilities

Vienna Model Basin Ltd has a complete range of model test facilities software tools and measurement techniques to test and simulate ships. The combination of these facilities and tools enables us to achieve reliable predictions of the performance and to improve the optimal operational use of the ship.

Towing Tank

Vienna Model Basin operates a towing tank of 200 m total length with a rectangular cross- section of 10 m width and 5 m depth. The basin is equiped with shallow water bottoms that can be adjusted to any water depth. At the end of the tank, a hydraulic wave maker is installed that is capable to generate regular and irregular waves up to a wave height of 0.6 m. The maximum towing speed of the carriage is 7.5 m/s.

Cavitation Tunnel

The depressurized cavitation tunnel is a Kempf & Remmers type K22 that can be run with two different measurement sections depending on the required flow speed. A maximum water tank speed of 12 m/s can be achieved and the test section pressure ranges from 0.1 to 1.0 bar. The wake field can be simulated by a wire mesh and dummy bodies. The cavitation tunnel has J25 and H39 dynamometers that can be operated alone or together, so that tests with counter rotating or tandem propellers can be conducted.

Wind Tunnel

Vienna Model Basin‘s wind tunnel has a test section of 2.800 mm x 1.500 mm and can generate wind speeds between 0.5 m/s and 28 m/s. The wind tunnel is an open return type with an open and exposable measurement section. The measurement platform can be turned by 360° and is able to accommodate models up to a length of 2 m. Below the turntable, a six-component balance and a smoke generator are installed. The boundary layer in the wind tunnel is adjusted to simulate the actual boundary layer at sea.

Pool Apparatus

Vienna Model Basin is able to determine the resonance frequency of swimming pools by testing models on an oscillating platform, the pool apparatus. Swimiing pools can be subjected to roll, pitch and oblique sinusoidal movements. The amplitude of the oscillation can be adjusted. In addition, the wave height can be measured in the model of the pool at various positions.

Outdoor Model Tests

Investigations on the manoeuvring behaviour that cannot be carried out in Vienna Model Basin‘s towing tank due to limited space and high speed can be conducted outdoors. The model’s behaviour is detected via a DGPS system that is corrected by a gyroscpoe and a magnetic compass in order to achieve the reuqired accuracy. Additionally to the ship‘s position and speed, ship motions and rudder movement are measured and recorded. All the necessary manoeuvres can be either manually or automatically controlled.

Numerical Facilities

For more than 25 years we provide our customers with numerical studies. The main tasks are hull optimisation, performance prediction and wake field calculation, which are performed with the commercial CFD solver Siemens Star CCM+, but also manoeuvring and seakeeping simulations that are carried out with our in-house software. For extraordinary calculations that are not performed on a daily basis we are able to revert to some dedicated partners.
