Milestone on Eurostars Project – Load Control for the Wavepiston Energy Collector (LOCWEC, E11849)

Fiellberg has developed for years pumping systems for wave energy Wavepiston concept. More information of this green energy concept can be found on the website
Now we have reached an important milestone as Wavepiston and Fiellberg have during 1½ years worked together in the Eurostars LOCWEC project on improving the control of the loads on the Wavepiston energy collectors. A proper load control is key to increasing the efficiency and durability of the system reaching a competitive levelised cost of energy and water.
One of the largest challenges for getting a competitive wave power system is handling the loads from the large waves, not only surviving the waves but also be durable to keep the costs for maintenance down. The large waves are not frequent, they count for less than 1 % of the year, but a wave energy converter must be designed to handle these and even the largest wave that can happen in a 100-year perspective.
Michael Henriksen, CEO of Wavepiston, explains: “In the project we have had a good cooperation with Fiellberg to develop and test an improved solution for load control in relation to the hydraulics and flip mechanism. The aim was to improve the energy conversion by having larger plates on the energy collectors, more durable pumps and reaching a 7-years lifetime”.
Juha Elonen, Managing Director of Fiellberg, follows up: “The Fiellberg telescopic pumps have undergone several improvements during the project. We are very thrilled to see that we have achieved a more durable design within a reasonable short time with the support of the Eurostars grant”.
The project has now been finalised. The improved load control system will be demonstrated in relation to two full-scale projects. One at Plocan, Gran Canaria, supported by EU’s Horizon 2020 SME Instrument, and one at a small tourist island, Isola Piana, Sardinia, supported by EU’s Horizon 2020 Fast Track to Innovation Programme.

Visit Fiellberg stand at Marintec Fair in Shanghai, China 3.-6.12.2019

We will be presenting our Hydraulic Cylinder Technology at Marintec Fair in Shanghai China on 3.-6 December 2019.
Our stand will be at Finland Maritime Pavilion in hall No. 2 Stand number is N2C6A-07.
We warmly welcome all our clients and partners to visit us. We will have representatives from Fiellberg’s Finnish and Chinese locations at the fair.

Fiellberg Oy has established a factory in Dalian, China

Fiellberg Oy has established a factory in Dalian, China. The opening ceremonies were held on 19:th of September. Factory has already been running for a while supplying some test hydraulic cylinders.
Now we have far more better possibilities to serve our clients in two continents. Our new factory can deliver full range of cylinders from minisize to jumbosize.
Here the cylinders are assembled with state-of-the-art equipment and we take special care of the cleanliness of the products. All parts are washed carefully and during flushing of the assembled cylinder, the oil cleanliness is monitored on-line.
Location of our Dalian factory provides excellent logistics possibilities for Japan and South Korea.

Fiellberg Reaches AAA Credit Rating

Fiellberg Oy is now ranked as a company with an AAA credit rating. In year 2019 only under 3% of Finnish companies have reached this rating. This important recognition aids us to maintain our image as a reliable companion to both old and new associates.



During the turn of the year both the Finnish and Chinese branch of Fiellberg have gained new members:


Heikki Kauranne started as a Technology Manager with Fiellberg Oy in January 2019. He is based in the Vantaa Head Office, where he is working on our product development. He is currently focusing on green energy and hybrid tech, specializing on wave power-based applications. Heikki graduated as M.Sc. (Tech) in 1988 and Lic.Sc. (Tech) in 2003, both from Helsinki University of Technology (today part of Aalto University). In 2013 he received a teacher qualification. Since his graduation until the end of 2018 he worked in the aforementioned university, acting as an assistant, a laboratory engineer, a researcher and a university teacher.


During his university career Heikki has participated in numerous research projects, prepared project applications, designed and implemented test installations, conducted large measurement programs, performed in-depth data analyses, and wrote several scientific publications. He has also actively developed hydraulics teaching and written a textbook on the subject. His main interests in the field of hydraulics research have been pumps, electro-hydraulic actuators, and energy-efficient systems.


Meanwhile in China Changbao Qu joined our ranks in late 2018. Responsible for quality assurance and production in FFT, Changbao has worked with mechanical equipment and hydraulics for almost two decades. In addition he has worked as a DNV-trained internal auditor in the past, experience which he will most certainly be using in his new vocation.


We welcome both of our new people to the growing Fiellberg Family!


Fiellberg Power Module is a digital-hydraulic hybrid device that could potentially result in significant energy savings in common cylinder applications. This product (patent pending) is currently in a proof of concept stage and is undergoing testing in Tampere University of Technology and Aalto University. We expect to see the Power Module ready for marketing by the end of the year, and we would be more than happy to provide more information in the meanwhile. Read more
