One Pump Suction, Two Environments: Refinery vs FPSO
The same process duty, a pump drawing from a separator, is laid out very differently on a refinery plot and on an FPSO deck. Here is how and why.
Firewater Ring Main: Onshore Plant vs Offshore Platform
Firewater systems sit idle for years and then must work perfectly. Onshore and offshore designs share that goal but solve it with different materials and layouts.
Flare Header Routing: Onshore Plant vs Offshore Platform
Flare headers collect relief from the whole facility. They must drain liquid, handle extreme temperatures and avoid vibration, and the layout challenges differ between a plant and a platform.
Open and Closed Drains: Onshore Sewers vs Offshore Drain Systems
Drains look simple, but mixing the wrong fluids or creating a gas path through a drain can cause serious incidents. Here is how onshore and offshore facilities separate them.
