Understanding Modular Skid-Mounted Equipment
What Is Modular Skid-Mounted Equipment
Modular skid-mounted equipment is a name given to pre-engineered, self-contained, steel-frame, or skid-mounted systems. The systems are designed for plug-and-play installation with little on-site assembly needs. They are widely utilized in gas processing, power generation, and industrial processes due to the fact that they are portable, have a small footprint, and are simple to integrate with installed systems. They offer an easy way of mounting complex processing units such as vaporizers, pressure regulating stations, and gas mixing modules. As they are pre-fabricated off-site, they save both cost and installation time significantly with guaranteed quality control.
Advantages of Modular Skid-Mounted Systems
- Saving in Installation Time: Pre-fabricated modules reduce on-site construction time by up to 80% compared to traditional stick-built methods.
- Cost Certainty: Factory-controlled construction minimizes field cost surprises and change orders.
- Better Quality Control: Standardized processes in controlled environments mean consistent quality.
- Space Optimization: Compact designs mean maximum processing capacity in small footprints.
- Scalability: Modular design allows for phased expansion and system upgrade capability.
- Enhanced Safety: Reduced field labor hours and pre-tested systems enhance overall project safety.
