Piping and instrumentation diagrams (P&IDs) are commonly used in the process industry as a transfer medium for the fundamental design of a plant and for detailed design, purchasing, procurement, construction, and commissioning decisions. The present study proposes a method for symbol and text recognition for P&ID images using deep-learning technolo...

A piping and instrumentation diagram (P&ID) is a key drawing widely used in the energy industry. In a digital P&ID, all included objects are classified and made amenable to computerized data management. However, despite being widespread, a large number of P&IDs in the image format still in use throughout the process (plant design, procurement, cons...

Piping and instrumentation diagram(P&ID) is an essential design document which is continuously modified and managed from design phase to O&M phase. For the ease of data transfer, P&IDs are generally converted into PDF which is hard to be modified. Therefore, engineering companies who need to manage P&IDs should manually re-convert their P&ID images...

With the rapid development of ICTs, condition monitoring has been used as a key technology in the plant industries. For reliable condition monitoring, sensors should output same values under same conditions regardless of time, but the sensitivity of sensors is gradually changed due to several factors such as temperature, humidity, contamination, ag...

Successful implementation of Model-based Systems Engineering(MBSE) obviously needs a model supporting efficient communication among engineers of various domains. The system modeling language standard, SysML is designed to create MBSE supporting models. However, SysML itself is not practical enough to be used for real-world engineering projects. As...

Engineering industry is considered as a key industry which will drive the future of Korea. However, Korean engineering companies have recently made a huge loss and the lack of engineering capability is pointed out as a main cause of this situation. Unlike Korean engineering companies, world leading engineering companies have their own systems Engin...

Projects on steel-making plant follow the stages of steel-making plant system life cycle. In each life cycle stage, there are exit criteria to be fulfilled before a project can continue to the next stage. Among the exit criteria, we focus on one of the technical exit criteria, that is, the technology maturity. Technology maturity is measured using...

During the industrial plant system life cycle, required technologies are developed and assessed to analyze their performance, risks and costs. The assessment is called technology readiness assessment (TRA) and the measure of readiness is called technology readiness level (TRL). The TRL consists of 9 levels and through the TRL assessment, the techno...
