Sea based trials with the prototype are now active in the Gothenburg archipelago
You might have seen a small demonstration ship with a wind turbine attached to the deck while visiting the northern Gothenburg archipelago. Our sea based trials are now up and running again after the winter holidays, collecting valuable data for the research project and our development processes. The tests will run for a couple of weeks.
Our wind turbine is approx. 6 meter high and the STENA Airmax demonstration ship is approx. 15 meter long. The test results are presented in the ongoing research projects’ final report, published in the end of March 2015. More updates will be presented shortly.

The prototype is active on the hill, soon to be connected to its prototype ship…
PROPit is happy to announce that we are testing our prototype in the Gothenburg archipelago now. The prototype, which is foldable, is approx. 5,8 meter high, has a blade diameter of 6 meters and is equiped with a 15 kW turbine manufacturered by Olsen Wing.
The land based tests are mainly to ensure that the functionalitites are in order and to prepare the automatic control system for the sea based trials in the near future.
The technology research project phase II with academia and industry experts is now up and running…
In 2013, Chalmers University of Technology and PROPit AB, supported by the Swedish Energy Agency, Region Västra Götaland, Stena Teknik, Wallenius, Lloyd’s Register ran the project "Development and demonstration of new technologies to harness wind power on ships.", also known as Phase I. The results from this were very promising and through extensive studies, the basic principles of the technique was verified.
Calculations for a specific route and the given conditions showed a potential for fuel savings of up to 16% with non-optimized wind turbines. Furthermore, it was shown that the installation and operation of large wind turbines on board gas and oil tankers can be done without in any way adversely affect the stability of the vessel or operation. An advanced prototype has been designed, built and tested in the Gothenburg archipelago which provides a basis for further experiments both on land and onboard ships.
A continuance of the first project was therefore initiated in August 2014 with the same actors and led by Chalmers in order to
- - optimize fuel savings of vessels using PROPits wind solution,
- - provide an industry overview of the attitudes and expectations regarding wind power on ships and
- - conduct a feasibility study to be able to initiate a large-scale demonstration project on a ship in authenitic conditions while it is in operation
PROPits basic technology is developed in a scientific manner using Chalmers research experts as well as industry experts in wind energy, construction and control technology to bring technology closer to commercialization.
Chalmers University of Technology is the Project Owner, through prof. Ola Carlson at the department of Energy and Environment.
Project Manager for both the completed phase I and the running phase II is Per Arne Nilsson.
