Our concepts: iowec & iswec
iowec - Intentium offshore wave energy converter: This wave energy project was formally started in 2007 by Intentium as. The concept is characterized by a long float moored to a front buoy and stabilized with its longest side normal to the incoming and dominant wave front. The float is again connected to a double-acting water pump with a buoyancy controlled water anchor attached at the lower end. The PTO has analogy with hydro power, and consists of accumulator, water turbine and generator. The concept is international patent pending through WO2011065841A1. Since start-up it has been conducted internal model tank testing and carried out several external feasibility studies by e.g. FugroOCEANOR and NTNU. Most recent and important studies are a numerical analysis by Sintef Marintek in 2011, and model testing in 2012 in the deep wave basin at Aalborg University through the EU FP7 project MARINET. The concept is a results of the company’s design guidelines.The various parts of this concept include:
- Wide stabilized main float
- Double-acting cylinder pump
- Water anchor Buoyancy controller of the water anchor
- Power take-off, PTO (accumulator tank, impulse turbine, El-Generator)
- Front buoy with the mooring system and the electrical subsea cable connections

iswec - Intentium short-crest wave energy converter: The companys first project iowec/iowep , is focused on offshore and long-crested wave conditions, with very high-energy seas. To have an alternative for wave conditions less offshore and with more choppy short-crested waves, like in the Skagerrak (the ocean-area outside Intentium's vicinity), the company have recently started a second wave power project/concept. The working title for this converter/project is iswec/iswep, where the 's' stands for short-crest. The concept is based on the same guidelines as has been the basics for iowep/iowec - still floating and installed far out from the coastline.
