Pipe systems are the main equipment and the same as main pipelines in a 
facility. It’s the result of the initially calculated process design where all 
the main equipment is decided. These pipe systems are in a later phase of the 
design broken down into detailed pipe parts, segments or spools of a pipe 
system. An example is a pipe system with Object ID: PM-411-PA-001 which consists 
of pipe parts with Object IDs, such as 0025-DC-PM-411-L-0001-C2S1-W2 and 
0080-DC-PM-411-L-0001-F1P1-W1. Both pipe parts belongs to the same pipe system 
PM-411-PA-001, but differ in size, pipe class, insulation type, heat tracing and 
sometimes service, e.g., they can serve as ventilation or drainage of the pipe 
system. This enables work and preventive maintenance to be monitored and planned 
by using a pipe system and all pipe parts within this pipe system. 
This structure could be created in two different ways:
