Understanding Skid Systems
A skid system, often referred to as a "skid-mounted system," is a pre-assembled, self-contained process unit mounted on a steel frame or "skid." These systems are engineered for easy transportation, installation, and integration into larger processes. Skid systems are commonly used in various industries, including oil and gas, chemical processing, water treatment, pharmaceuticals, and food and beverage production.
Design and Engineering of Skid Systems
Modular Design:
Skid systems are designed with modularity in mind, allowing for the combination of multiple skids to form a complete processing system. This modular approach provides flexibility and scalability, enabling easy system expansion or reconfiguration. Each module can be individually optimized and then integrated seamlessly, ensuring that the overall system performs at peak efficiency.
Pre-assembly and Testing:
At ERGIL, we pre-assemble and rigorously test our skid systems in a controlled environment. This ensures that each system meets the highest standards of quality and performance before being shipped to the installation site. Pre-assembly reduces on-site construction time and minimizes the risk of installation errors. Our state-of-the-art testing facilities allow us to simulate actual operating conditions, ensuring that each skid system functions as intended under all scenarios.
Compact and Space-efficient:
Skid systems are engineered to maximize space efficiency, fitting into tight spaces and allowing for easy transport. This compact design is particularly beneficial for offshore platforms and remote locations where space is limited. The design process involves detailed 3D modeling and spatial analysis to ensure that all components fit perfectly within the allocated space without compromising accessibility or maintainability.
Integration of Components:
ERGIL's skid systems are equipped with all necessary components, including pumps, valves, piping, instrumentation, and control systems. These components are integrated into a single frame, ensuring seamless operation and ease of maintenance. The integration process includes the use of advanced control systems and instrumentation to monitor and control all aspects of the process, ensuring optimal performance and safety.

Safety Considerations in Skid Systems
Safety is a paramount concern in the design and operation of skid systems. ERGIL incorporates several safety features and best practices to ensure the safe operation of our skid systems:
Pressure Relief Devices:
Skid systems are equipped with pressure relief valves and rupture discs to prevent overpressure situations, protecting both personnel and equipment. These devices are designed to activate automatically when pressure exceeds safe levels, releasing excess pressure to prevent equipment damage and ensure safety.
Instrumentation and Controls:
Advanced instrumentation and control systems monitor process parameters in real-time, providing early warning of potential issues and enabling prompt corrective action. These systems include sensors, transmitters, and control valves that provide continuous monitoring and control of pressure, temperature, flow, and other critical parameters.
Emergency Shutdown Systems:
Automated emergency shutdown systems (ESD) are integrated into skid systems to quickly and safely shut down operations in the event of a hazardous situation. These systems include safety relays, emergency stop buttons, and interlocks that ensure a rapid and safe shutdown of the system in case of emergency.
Hazardous Area Classification:
Skid systems are designed and certified for use in hazardous areas, ensuring compliance with international safety standards such as ATEX and IECEx. This includes the use of explosion-proof equipment, intrinsically safe devices, and proper grounding and bonding to prevent ignition sources.
Material Selection:
Materials used in skid systems are carefully selected for their chemical compatibility, mechanical strength, and resistance to corrosion, ensuring long-term reliability and safety. This includes the use of stainless steel, high-alloy materials, and corrosion-resistant coatings to withstand harsh operating conditions.
Advantages of Skid Systems
Cost Savings:
Pre-fabrication and testing in a controlled environment reduce field labor costs and minimize onsite construction time. This results in significant cost savings and improved project timelines. Pre-fabrication also allows for better quality control and reduces the risk of rework and delays due to onsite issues.
Quality Control:
Manufacturing in a controlled environment ensures high quality and reliability of system components. ERGIL’s stringent quality control procedures guarantee that each skid system meets the highest standards. This includes non-destructive testing (NDT), hydrostatic testing, and material certification to ensure the integrity and performance of all components.
Flexibility and Scalability:
Skid systems can be customized to meet specific process requirements and easily scaled by adding more skids. This flexibility allows for future expansion and adaptation to changing process needs. Skid systems can be designed for modular integration, allowing for easy addition or removal of units to accommodate changes in production capacity or process requirements.
Reduced Downtime:
Since skid systems are pre-tested, they typically require less time to get up and running once delivered to the site. This reduces downtime and ensures a smooth startup. Pre-testing also allows for the identification and resolution of any issues before the system is installed, further reducing the risk of delays and operational disruptions.
Mobility:
Skid systems can be relocated if necessary, providing flexibility for temporary installations or future plant modifications. This mobility is particularly advantageous for remote and offshore installations. Skid systems can be easily disassembled, transported, and reassembled at a new location, providing flexibility and adaptability for changing operational needs.
