Taylor Wharton VT-18000-LNG — 18,000 L Vertical Cryogenic Storage Tank

What is the current vacuum reading, and what is the NER?

The listing does not provide current vacuum readings or normal evaporation rate figures for either unit. Request recent vacuum readings in microns and NER in percent per day from the seller, along with documentation of when these measurements were last taken. On vertical cryogenic tanks of this size and age, vacuum degradation is the primary concern; acceptable readings typically run below 50 microns, and NER should be under 0.5% per day for LNG service.

Is the data plate legible, and is the U-1A available?

The listing confirms NBD 93967 but does not address data plate condition or U-1A form availability for either unit. Both the nameplate and the original U-1A manufacturer's data report are essential for insurance, compliance, and any future re-stamping; request photos of the data plate and copies of the U-1A from the seller before inquiring further. Vertical tanks of this vintage should also have a U-1A partial data report if any repairs were performed.

What is involved in relocating and re-commissioning it?

The tanks are located in Waxahachie, TX. Relocating an 18,000-liter vertical cryogenic tank typically requires a heavy rigger familiar with vacuum-jacketed vessels, crane work to lift the unit, and transport on a flatbed; the inner vessel must not be shocked or the vacuum integrity can be compromised. Re-commissioning typically involves re-leveling on a concrete pad, verifying vacuum integrity, pressure testing per CGA S-1.3, recalibrating or replacing pressure relief and instrumentation, and obtaining any required state or local pressure vessel inspections before filling.
