The Pump Failure Model

Client: Coastal RefineryOil refining · Teesside

Coastal Refinery control room, Teesside · Careful, safety-first

Coastal Refinery wants to know which pumps will fail before they do, so maintenance happens on a Tuesday afternoon instead of at three in the morning. Years of shift logs exist to learn from, exported through a broken ETL job that transposes them. Safety signs off on everything.

Team goal · 2,500 gems

Everyone on this contract works toward one sign-off from Coastal Refinery. Sign-off means the model watches every unit and the refinery's sister sites follow.

Who you'll work with

Laura CollinsYour lead

Engineering Lead

Dry, warm underneath, short sentences. Notices how you did. Never gushes.

Alison Boyd

Control Room Lead, Coastal Refinery

Exact, calm, safety above all.

Theo Barker

Senior Developer

Friendly rival. Competitive banter, always generous in the end.

The client's system

Broken export

Keyword columnar transposition on the shift logs, with less of the key logged on nights, and pipelines hiding a transposition among encodings.
