History

In 1992,

(DNV) was hired by the Norwegian authorities to develop technology to detect any remaining oil in the sunken German WW2 warship Blücher. The technology they advised was based on acoustic resonance, and it was discovered that as a bi-product it can also be used to measure the thickness of metallic plates. This discovery was the foundation of DNV's effort to develop a whole new inspection technology, based on ART (Acoustic Resonance Technology). John D. Breivoll had worked closely with DNV to inspect sewer mains since the 1980s. Since there were no good methods to inspect water mains in the same way as one can inspect sewer mains, John D. Breivoll saw the potential of the ART technology for the water sector, and while DNV primarily saw the use of the technology in oil related industries, John D. Breivoll started Breivoll Inspection Technologies AS with Arne Christian Vangdal in 1998 to license ART for the water sector.

Technology

To be able to inspect water-filled distribution mains, the company has developed a Pipescanner which is neutrally buoyant and carries 64 custom-made

s through the water pipe. The scanner collects roughly 200 MB of acoustic resonance data per meter, which is then stored and sent to analysis. A custom software-suite based on ART (Acoustic Resonance Technology) is then used to translate the resonance data to information about remaining wall thickness, internal corrosion and external corrosion.

Awards

BIT were the recipients of the 2007 Norwegian Engineering Award, given by the technical magazine Teknisk Ukeblad "for their work within socially beneficial infrastructure management". In 2008, the Norwegian Research Council awarded the first Industrial Ph.D. stipendhttp://www.forskningsradet.no/en/Funding/naeringsphd/1235469223842 Description of the Norwegian Industrial Ph.D. program to BIT and to their employee Martin Skjelvareid Hansen.
