The geometrical recording of the plant can be carried out by means of laser scanning, either with a base station with a geometrically known position and/or a mobile hand-held scanning device which scans the surfaces without touching them. By combining the 3D scanner with a thermographic camera, the infrared measured surface temperatures can be attributed to 3D measured surface dimensions and, like this, complete the TIPCHECK audit in one go.
Furthermore, with this collected information, the actual heat losses can be calculated, and the sizes and dimensions of special shapes like valves available as STL or CAD files can be further processed to build the tailored insulation solutions to stop the energy waste and repair the existing system. One of the biggest challenges of the research project is to find how to embed this information automatically into existing planning software to build the specific solution like tailored insulation boxes on valves or pairs of flanges.
The research as such is led by Prof. Dr. Eng. Stefan Knoblach from the FHWS’s laboratory for engineering and industrial surveying and Prof. Dr. Eng. Winfried Wilke from the FHWS’s laboratory for technical metrology and experimental stress. Together with their dedicated team, including scientific worker Sabine Roman and the project coordinator Sebastian Fiedler, and with the support of the two Master students Georg Karl and Philipp Grümpel the first steps have already been made.

In its last meeting in 2016, the research project established a Steering Committee comprised by one representative of each partner and chaired by the EiiF Foundation Director Andreas Gürtler. The insulation experts (see picture below) and the University project team meet in regular workshops to give practical input, exchange experience and know-how and support that developments are very much focused on the TIPCHECK and insulation needs.
In this week’s workshop at the FHWS in Schweinfurt, on 15 and 16 February, the eDIan partners met and witnessed the first achievements, and further developed single working packages defining the next short to medium term goals:
- Establish 3D semi-automatic elements from scanned uninsulated objects in an inexpensive and time efficient manner;
- Develop a methodology to make quantitative temperature measurements on several hotspots in an existing installation.
After the workshop, the group of partners agreed that the research project is well on track but remains very challenging. We will further report about the progress of eDIan on the EiiF’s website and in our newsletter. Meanwhile, if you are interested to follow the developments of eDIan on a regular basis, please send an email to firstname.lastname@example.org with the subject “eDIan” and you will automatically receive regular updates on the project progress.
