Long term corrosion rate.

This is calculated using a chosen ILI report and the growth rate is calculated on the assumption that the growth rate has been constant since the creation of the pipeline.

At it's most fundamental the calculation is simply p / t where p is the property (either the depth or length of the anomaly) and t is the time gap between the creation of the pipeline and the ILI report date.

Input

Arguments

• org_id: as string which should be a valid uuid for the organization
• project_id: the id of the data project where the pipeline data is found
• pipeline_id: an array of strings which should be valid UUIDs for pipelines
• ili_id: an array of strings which should be valid UUIDs for ili sequences
• aggregation: an string each value should be one of the following
  • segment
  • pipeline
  • girth_weld
  • every_1_km
  • every_5_km
  • every_10_km

Creating the function on the platform

To create this function on the platform using the cli set up the port forwarding as shown in README.

Then run the following command to create the function.

cargo run functions create \
  -f functions/acr_long_term_corrosion_growth_rate \
  -d "Run the long term corrosion growth rate calculation on using the provided ILI" \
  -i org_id=string \
  -i project_id=string \
  -i pipeline_id=array \
  -i ili_id=array \
  -i aggregation_method=object

Testing the function locally

You can run and test the function locally by running

cargo run

Then you can check it work with curl as follows

curl localhost:8080 -d $(jq '. | tojson' functions/acr_long_term_corrosion_growth_rate/example_input.json)
