Cognite Data Fusion: Use Case for a Reliability Engineer in Charts

Cognite Charts Team, 

I would like Cognite Charts and CDF help

User From Celanese:

Here’s my scenario – I’m going to be as vague as an actual problem statement that we would get –

At the base of T109 are a set of pumps.  I believe they basically pump on-spec AA to the tankfarm.  They have been debottlenecked so much over the years that they have essentially run out of NPSH.  The scenario is to find the NPSHa of these pumps and figure out how often they cavitate and cause upsets (I’m honestly not sure if they do or not).  To do a full analysis on that we’re going to need:

• The NPSHr of the pumps (pump datasheets aren’t in Bentley, so that’s a problem but I can get it)
• The historical level in T109 and the ability to translate that level in actual ft of elevation
• The elevation of T109 relative to the pumps (ie, the isometric on the pumps’ suction or 3D)
• The temp in T109
• The flow from the pumps to the tank farm
• The ability to correlate drops in flow to the T109 level and temperature
• Any other time series around this system that may be helpful in the analysis
• We can then build a calculation showing the NPSHa of those pumps and track it in real time – ideally we would also set an alert when it started to get marginal

How would i get to the last point without speniding hours searching in CDF and then flipping to Charts? Any ideas how i can have all that to build the caclulation in Charts. Access to ISOMETRICS, 3D, Time series and P&ID
