What is Modularisation Inspection?
“Modular” is a construction method that involves constructing sections away from the building site in a fabrication shop. Modules are more accurately called prefabricated prefinished volumetric construction as part of the overall plant design following certain predefined design and fabrication principles.
Ideally a module is in itself completed considering structural, piping, process equipment, valves, electrical and instrumentation works with precise interconnection points. Scope and ITPs will determine the minimum level of structural completion for inspection.
Modularization inspection is performed onsite the fabrication workshop in various predefined intervals by experienced quality and construction experts. They will follow the detailed ITPs and schedule performance such as:
- Level of Scope completion
- Visual Inspection
- Compliance to Standards and Specifications
- Compliance to Design and AFC drawings
- Material Compatibility
- Valves
- Junction Boxes and instrumentation
- Cabling and wiring
- Welding Consumables and Auxiliary Materials
- Forming
- Welding Joints
- Welder’s Qualification Tests
- Welding Procedure Tests
- Penetrant Inspection
- Radiographic Inspection
- Hydrostatic Test
- Tie-in points
- Pressure vessel certificates and compliances
- Ladders, Platforms, Grids, Walkways
