Osscad and CJ Kelly bring liner curing monitoring to the UK market
Jan 27, 2017
Germany-based OSSCAD GmbH & Co. KG specialises in the design, development, support and technical consulting for optical sensor technologies. The company places a special emphasis on the ongoing development and promotion of its products in the area of CIPP (cured-in-place pipe) rehabilitation and monitoring of buried energy cables. In 2017 OSSCAD will celebrate its 10th anniversary.
The CMS system consists of a CMS measuring instrument (laser radar), a fibre optic cable (LWL cable) as a line-shaped temperature sensor (CMS sensor cable) and the CMS application software (VISCOM liner) for the evaluation and visualisation of the curing temperature measuring data.
The CMS System has been patented in Germany since January, 2010 and the USA and European markets since 2012. Since 2013 the CMS procedure has been used in Europe, the USA, South America and Australia on more than 2,500 installations.
How it works
The CMS system can be utilised with all types of liner curing techniques including Hot Water, UV and Steam. It simply monitors the temperature change over the cure period at the liner outer skin so works correctly irrespective of the curing technique
In practice once the pipeline to be lined has been cleaned and prepared, a sensor cable is drawn into the section being lined. The liner is then installed in the usual manner so that the sensor cable contacts with the outer skin of the liner. The sensor cable is then connected to the monitoring system and as the curing operation progresses the temperature changes of the liner are registered. The changing temperatures are then displayed as a colour graph that indicates not just the temperature change but also any hot or cold spots or areas where the reaction is not proceeding as might be expected. The output from the senor cable and monitor can be stored for future reference should it be necessary.
Ursula Heising of OSSCAD GmbH & Co. KG said: “In short, the CMS is characterised by an easy-to-use, robust system of components and a very competitive software package which offers new possibilities for renovation companies and their customers.”
The advantages of using the CMS System include:
- On-line monitoring of the thermal curing process during the rehabilitation operation
- Colour marking when the required minimum liner cure temperature is achieved which therefore offers a clear decision support for the rehabilitation companies especially on difficult construction sites
- Reduction of the energy costs and CO2 emissions
- High-level proof of the thermal curing process over the total length of the liner and for the whole duration of the rehabilitation operation
- A rise of the acceptance of tube liners with rehabilitation companies and local authorities
As part of the operation to bring the CMS system to the international market, OSSCAD recently announced that Peterborough, UK-based C.J. Kelly Associates was now the new UK Partner for distribution of the system across the UK and Ireland. C.J. Kelly International will also be able to offer the system on a more global basis.
Commenting on the new partnership John Kelly of CJ Kelly Associates said: “Monitoring of the liner curing process to ensure that the whole liner product has been fully and correctly cured has been something the rehabilitation industry has been after for about 20 years. Now the CMS system offers just that. With some 25 years plus experience of the pipe lining sector with our various liner and support product ranges we can see just effective the CMS system will be for both lining contractors and clients alike. For the first time in the industry’s history we now have a system that will show in real time how a curing operation is running and still provide a record of the process for back reference.”
