Designing Piping for FPSO Hull Deflection and Vessel Motion
On a floating unit the deck itself moves. Hull bending and wave-induced motion become load cases in the stress model, and they shape how topside piping is routed and supported.

Thermal Expansion on a Long Rack Run: Loops or Expansion Joints?
A hot hydrocarbon line across a refinery unit grows by hundreds of millimetres. Here is how the growth is calculated and why loops usually beat expansion joints.
Duplex and Super Duplex Stainless Steels in Offshore Piping
Duplex steels give strength and corrosion resistance at a sensible weight, which is why offshore topsides use so much of them. Getting the welding right is the hard part.
Slug Flow Loads on Piping: Why Two-Phase Lines Move
In two-phase lines, slugs of liquid travel at gas velocity and hit every bend. The resulting forces can shake a line off its supports if they aren't designed in.
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.
