1MOEK (Moscow District Heating Company)"As the world's largest district heating company, operating in a northern continental and therefore periodically very cold climate, we have the highest obligation towards our clients in terms of keeping them warm. This has a health and safety aspect of paramount importance. Breivoll is the only company we have found that can provide us with the level of detail regarding both external and internal corrosion as well as pipe thickness, which allows us to make accurate risk assessments of what are very high pressure pipes. We have found the very highest correlation in the reported results when compared with physical inspection afterwards. Congratulations to Breivoll!“
2Oslo Water and Sewerage Works (VAV)“VAV has a large-scale ongoing rehabilitation plan, where inline and no-dig techniques are preferred. To determine which pipes can be lined and which must be renewed, and which can be left for later, VAV has selected Breivoll Inspection Technologies. About 25 kilometers (more than 3000 pipes of 6 m length) of water pipe network has been inspected by BIT. The results are digitized in the ArcGIS geodatabase system and consist of information about residual pipe thickness, internal and external corrosion, type of corrosion. This is crucial information in deciding which actions to take for a given pipeline.”
3Tromsø municipality (Norway)"Tromsø municipality used BIT to determine that only a short section of a multi-kilometer water main installed between 1978 and 1986 had risk of new breaches. This reduced our rehabilitation costs by approximately € 800k.”
4Groningen Waterworks (The Netherlands)“BIT is the only inspection company that satisfies the strict requirements of the Groningen Waterworks, a large water supplier company in The Netherlands. Based on BIT inspection, we were able to determine that an important water main would last for at least 20 more years, enabling us to postpone an € 8 million investment.”
5Mälarenergi ABIn 2016, we contacted Breivoll lnspection Technologies, who presented their technology for internal pipe inspection.
We became interested in the technology because it opens up new opportunities in the rehabilitaion work on Mälarenergi's district heating network.
lnstead of working responsively with corrective maintenance, we can work more proactively.
We believe that in the long term there is the possibility of saving money by working more proactively, especially on larger pipe dimensions.
Mälarenergi chose to try the technique on a district heating pipeline, DN400 with a length of about 200 m, which is located under several train tracks in central Västerås.
The result of the test was positive. Not only the technology seems to work but also that the district
heating pipes was in good condition despite its age.
The district heating pipes will not be renewed for at least 10 years.
Mälarenergi looks forward to Breivoll's future pipeline inspection of district heating pipelines on larger dimensions.
