text: I have never done any work offshore at all. Now the gas compressors I worked on moved any where from two million cubic feet a day or more. The smallest units we built weighed in at 90tons. Some where built to hold up to 6,500lbs or working pressure. My main job on them were to build the pressure vessels that all units use. This is ASME Code weld procedures so I am very familiar with X-Ray procedures on heavy steel
