Brownfield work is where piping design gets real. No blank canvas, no perfect dimensions, no guaranteed clearances. This section covers the methods, mindset, and hard-won lessons that make brownfield projects survivable.
Greenfield design is a controlled problem. Brownfield is a detective game. You're working with incomplete records, degraded structures, undocumented modifications, and a plant that's been operating for twenty or thirty years with no obligation to match its own drawings.
After seven years of brownfield and revamp work, I've built a set of approaches that consistently reduce surprises — not eliminate them, but reduce them to a manageable level. That's what this section is about.
"The plant always wins. Your job is to understand it well enough to work with it, not fight it."
— A lesson from a 35-year veteran, somewhere on a Port of Rotterdam turnaroundHow to systematically verify existing conditions before committing to a design. Field walkdowns, drawing markups, and the discipline of treating every dimension as unconfirmed until you've personally checked it.
Read tips âTie-ins are where brownfield projects go wrong. Flange face conditions, buried connections, isolation requirements, and the coordination required to execute a tie-in cleanly during a shutdown window.
Read tips âHow to find routing conflicts before they become site problems. Manual methods, 3D model clash checks, and the visual verification habits that catch what software misses.
Read tips âFinding a path for a new line in a fully congested plant. Pipe rack strategies, corridor prioritisation, and the art of convincing other disciplines that you need their space more than they do.
Read tips âHow piping design decisions affect the duration and complexity of a shutdown. Designing for constructability under time pressure, minimising hot work, and sequencing that accounts for operational reality.
