Digitisation and processing of your analogue plant documentation with plant designation / plant labelling

Together with our partners, we have developed a new technology that we use to prepare existing technical documents, such as drawings or documents, in such a way that it is possible to digitally evaluate plant information such as plant labels, technical data and metadata.

Step 1: Fine scanning of the drawing

We use a precision scanner to convert the drawing to a raster format. For this we require the original drawing or a copy of the following:

• The P&I diagram
• The construction drawing
• The E-technical drawing
• The site plan
• The building plan
• The hydraulic diagram

Step 2: Vectorization/Structuring of the CAD file

We implement intelligent vectorization to digitalise drawings and convert them into a CAD file without having to painstakingly redraw them. By assigning attributes to the vectors, a colour and layer structure is created that is comparable to newly drawn documents. Finally, we check the drawings again for their dimensional accuracy and content. Hereby, we carefully compare them with the original.

Step 3: Intelligent text generation for information evaluation

We convert the available plant designation/label by using a text recognition procedure into digital and thus searchable texts. After that, we convert all plant designations/ labels again into text attributes / technical data. In this way, we create the conditions to evaluate the plant designation.

Step 4: Evaluation and Testing of the plant designation

The plant deisgnation is entered in the drawings in different ways. Sometimes it is complete from the system to the equipment unit level, whereas at other times only the equipment unit labels are available. The latter is usually the case for measurements and isolation valves. In order to conduct a qualitative evaluation, it is imperative that all plant designation codes are available in the same structure. This is the reason why we work on the structure in this step. So that no changes to the layout have to be made to the plant designation plant labels, which are only displayed up to equipment unit level, we present this additional information to the system level as non-visible information. Due to the fact that the structure of the plant designation has now been standardized, an evaluation can now finally be carried out.
