Successful Cooperation With Carnegie Clean Energy


Carnegie Clean Energy and NEMOS are collaborating in the field of wave energy technology. The joint work with the Australian company began with tank testing campaigns in 2014 and 2016, during which NEMOS provided the model scale power take-off for the Carnegie wave energy converter (WEC).

The collaboration became more intense in 2018 within the development of Carnegie’s new multi-moored wave energy converter CETO 6M. In addition to supporting the tank testing campaign at the University of Plymouth (GB), NEMOS was selected as one of the contributors in the development of a rotary power take-off system (PTO) for the “Albany Wave Energy Project”. Currently, NEMOS is working on design and manufacturing solutions for the mechanical power transmission system of the 25 m diameter full scale WEC.

Rope Testing With Innovative Rope Constructions


In cooperation with LIROS®, our partner for rope solutions, we have been performing cyclic bend over shave tests (CBOS) with fibre ropes at the Institut für Fördertechnik und Logistik (IFT) in Stuttgart for several years now. With a new developed rope construction, we achieved 2.5 times longer lifetime compared to the previously tested standard rope.

The image shows a blue 12-strand hollow braided Dyneema® rope after about 1.3 million bendings. The yellow rope is the new developed 5-strand flat braided Dyneema® rope after the same number of cycles. On the pictures it is clearly visible that the blue rope shows higher wear and tear compared to the improved yellow one. The numbers emphasise the significant increase in lifetime: the blue rope failed after 1.3 million cycles while the yellow rope is still being tested and has already reached 3.2 million bendings to this day.


ON TOUR - Zwischen Rhein Und Ruhr


On 3rd of February NEMOS will demonstrate its impressive PTO test bench within "ON TOUR - Zwischen Rhein und Ruhr". This series of events is initiated and accompanied by Duisburg`s mayor Sören Link and will this time focus on education and future technologies. Please feel cordially invited to join and click here for more information and registration to join the whole program:



As a leading technology developer in the field of wave energy, NEMOS got invited to join the Horizon 2020 funded project „Space@Sea“. The consortium consisting of 17 European partners aims to provide sustainable and affordable workspace at sea by developing a standardised and cost efficient modular island with low ecological impact. In this context, NEMOS will contribute by developing technology for using wave energy from the relative motion between the separate modules. Here, enormous forces at relatively small amplitudes require a special designed PTO. NEMOS is looking forward to a fruitful interexchange of know-how within a broad international consortium.

NEMOS At The Ocean Energy Europe 2017


NEMOS is attending the Ocean Energy Europe Conference and Exhibition - a leading European event dedicated to ocean energy. We will give you an update of our current PTO status and outlook during the session “Wave Power Take Off - Have we cracked it?”. Contact Alexander Martha ( if you want to get in touch during the 2 days conference on 25-26 October in Nantes. » Download our presentation slides here.

Relaunch Of Our Website


The diligent design of the components of our wave energy device led to the engineering of numerous innovative products, too. To put them to the acid test, we developed specific test benches in on- and offshore environment. By now, the interest in and demand for them has become so large that two new business areas arose: the engineering of innovative components and the provision of individualized test facilities. At the same time, the prototype of our wave energy converter is further being developed and will be installed in the Belgian North Sea soon. We have taken this gratifying business development as an occasion to relaunch our website and are pleased to welcome you here!

Soil Investigations At The Installation Location


NEMOS successfully performed an in-situ soil investigation at the planned installation location near the Port of Ostend. The Cone Penetration Test (CPT) was performed using the Lynn barge from contractor Artes Depret, which carried a 20 ton CPT rig from SGS Geotechniek. The results of this test will be used to verify the stability of the research structures' foundation.

Successful Completion Of The 1:5 Long-Term Test


Since October 2016 NEMOS` 1:5-test device in Nissum Bredning (Denmark) has permanently been in fully automated operation, with remote monitoring from the office located in Duisburg. During the several month-long failure-free operation frequent and diverse winter storms occurred with significant wave heights of more than 1.5 m. This equates to a full scale wave height of 7.5 m.

NEMOS Joins The OMAE In Trondheim


The belt-system developed by NEMOS has been presented at the "Conference on Ocean Offshore & Arctic Engineering" (OMAE) in Trondheim. The patent pending system has been specially constructed for the rough operating conditions within the wave energy converter. Due to the innovative system a long-term operation of belts with variable driving directions is also possible for other industrial applications. » Get Full Article

Permit For The Prototype Location


After an investigative procedure lasting several months, which included a public hearing and numerous detailed examinations, the Belgian authorities have permitted the installation of the test-device in the North Sea close to Ostend. The permission includes the construction of the wave energy converter with its tower structure as well as the license to execute the planned research activities for a duration of three years.
