Increasing LNG Plant Capacity with Confidence
Expanding LNG capacity safely demands more than steady-state assumptions. In this white paper, CB&I – an industry leader in LNG infrastructure – shows how it increased an existing facility’s send-out rate by 60% while managing surge risk in the boil-off gas (BOG) system, where level-control valves can shut in just three seconds.
With no benchmark data from the 1999 build, the team turned to Datacor’s Impulse transient analysis software to model pre and post-expansion scenarios, quantify potential waterhammer, and translate complex hydraulics into clear visuals for stakeholders. Using real-world piping geometry, Impulse simulations confirmed that even with higher flow from additional tankage and pumps, maximum pressures remained below the design threshold (15.5 barG/225 psig).
Just as critically, Impulse’s force calculations fed a structural review that verified existing pipe supports could handle surge-induced loads, avoiding costly rework. The paper highlights how engineers used Impulse’s reporting and isometric drawing modes to communicate results, test ‘what-if’ conditions, and build confidence in decisions before construction. For LNG operators facing upgrades or greenfield designs, the takeaway is clear: surge analysis is no longer optional. With Impulse, teams can anticipate transients, validate protection strategies, and deliver capacity increases without compromising safety, uptime, or equipment integrity.
