The world is about to learn a very difficult less in MCHR machinery: Cryogenic heat exchangers (MCHE) - the core of every LNG train
Made by only one company at scale: Air Products & Chemicals (APCI). Lead times alone are 3-4 years per unit. Ordering 14 simultaneously is impossible - the global manufacturing queue would stretch to ~8-10 years for all units. Each train's main heat exchanger is a custom, building-sized cryogenic vessel.
Iran is about to destroy all of these currently in use in Qatar. The entire world will lose roughly 25% of LNG exports for 10+ years if this happens.
You are NOT ready for this.
