As fitted drawing意思
"As fitted drawing" is a term used in engineering and construction, particularly in the field of mechanical engineering and naval architecture. It refers to a type of technical drawing or diagram that shows the actual installed configuration of equipment, components, or systems. These drawings are typically used in the operation, maintenance, and repair of complex systems where the original design may have been modified during installation or commissioning.
As fitted drawings are different from standard engineering drawings or design drawings because they reflect the real-world configuration of the equipment. They can include details such as:
- The exact location of equipment on the premises or within a structure.
- Modifications made to the equipment during installation.
- Adjustments made to the design to accommodate site-specific conditions or requirements.
- Labels or tags that correspond to specific parts or components for maintenance purposes.
- Wiring diagrams or piping configurations that may have been altered from the original design.
These drawings are important for maintenance personnel, engineers, and other professionals who need to understand the current state of the system. They can help in planning repairs, overhauls, or upgrades, and can prevent errors or damage that might result from working from outdated or incorrect information.
As fitted drawings are commonly used in industries such as oil and gas, chemical processing, power generation, and shipbuilding, where large, complex systems require detailed documentation of their installed configuration.
