In a large-scale project like the Nord Stream pipeline, transparency in the construction phase is critical. Therefore all components - pipes, buckle arrestors, valves, etc.- have to be identified by a unique number. If for example a faulty pipe has been detected, typical questions to be answered include : which other pipes are affected by similar failures and where are they located. All detections and determinations of failure causes with current status have to be documented by the contractors, while Nord Stream need to have ongoing visibility of the same. In addition to the logistics information as to where a pipe is located - production process, transport or storage - and when a pipe is expected in the yard is vital for precise planning and execution.
To meet these and other requirements Nord Stream implemented a comprehensive Pipe Tracking System (PTS). The PTS is based on a modern standard Manufacturing Executions System (MES) supplemented with an information portal, where all contractors are required to submit the requested data documenting the various production steps in their plants and yards.
As a result of this approach, Nord Stream is able to query at any point of time with the greatest possible level of detail all information related to a single pipe and is able to visualize in GIS where the pipe has been laid. In parallel, all required certificates are generated automatically.
