Case Study: PETRONAS CARIGALI cuts troubleshooting from weeks to minutes and prevents unplanned shutdowns with OSIsoft's PI System

Faster Problem Solving with the PI System

PETRONAS Carigali, the upstream arm of Malaysia’s national oil and gas company, operates 190 offshore platforms producing over 2 million barrels per day. The company faced fragmented, siloed data on each platform, no real‑time visibility for operators, and slow troubleshooting that required engineers to fly offshore, download data and take up to three weeks to analyze incidents—costing millions when automated shutdowns occurred.

PETRONAS deployed the OSIsoft PI System with local PI Servers on platforms and secure one‑way feeds to regional and central servers, giving operators and on‑shore engineers a shared, real‑time view of operations. The change reduced diagnostic time from weeks to minutes, enabled remote root‑cause analysis, prevented five unplanned shutdowns at one platform in the first year, and provided company‑wide KPIs; by 2013 PI Servers were installed on 8 of 52 mother platforms with further rollouts planned.
