Many of the vessels we produce are built in the field at customer facilities.? In fact, SFI has five crews dedicated to working on location.? A portion of the work takes place in the Springfield, Missouri plant to ensure the materials are ready for the crew so they can begin their work as soon as they arrive. The material is preprocessed, meaning it is sheared and rolled prior to shipping to the field.? Accessories such as ladders, platforms and handrails are built in the shop and shipped, ready to install on-site when needed.? Components such as internal pipe coil and manways are also shipped ready to install.? Preparing the work in this way helps to make the field portion of the work highly efficient.?
