1. Fabricated weight: Total weight as fabricated in the shop. 2. Shipping weight: Fabrication weight plus any weight added for shipping purposes, such as shipping saddles. 3. Erection weight: Fabrication weight plus any weight installed for the erection of the equipment, such as any insulation, fireproofing, piping, ladders, platforms. 4. Empty weight: The overall weight of the vessel sitting on the foundation, fully dressed, waiting for operating liquid. 5 . Operating weight: Empty weight plus any operating liquid weight. 6. Test weight: This weight can be either shop or field test weight, that is, the vessel full of water.
