CCH Custom Build 40 ft ISO Frame — 700 gal LNG Storage

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

The listing does not provide the current vacuum reading or normalized evaporation rate. Request these from the seller along with documentation showing when the vacuum was last measured—on LNG vessels, NER typically increases over time as the vacuum degrades, and anything above 1-2% per day suggests the vessel may need re-insulation or evacuation before it's economical to operate.

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

The listing does not address data plate condition or documentation availability. Ask the seller for photos of the nameplate and copies of the U-1A manufacturer's data report, ASME U-1 form if applicable, and any recertification records—without these, you'll face delays or inability to register the vessel in most jurisdictions.

What is involved in relocating and re-commissioning it?

The 40-foot ISO frame makes this unit compatible with standard intermodal handling equipment and flatbed transport. Re-commissioning typically requires vacuum integrity testing, pressure vessel inspection per local jurisdiction requirements, vaporizer function testing, and verification that relief devices are in-date—ISO-mounted units like this are designed for relocation, but budget time for any required hydrostatic testing or recertification depending on how long it has been idle and your operating authority's requirements.
