Modular process skids are systems constructed in steel-reinforced, transportable frames. They represent a truly innovative and streamlined process that enables simultaneous on-site and off-site construction, improving project control, safety, and quality, reducing waste, and other benefits. These complex, mobile process systems can provide a practical solution to certain projects that require alternatives to traditional design and construction methods.

This article will discuss modular process skid design, highlighting the advantages of modular construction, key considerations, and important design guidelines.  

What is a Modular Process Skid-Built System?

A modular process skid is essentially a portable, compact system that encapsulates an entire process system within a steel-reinforced frame, which increases durability and enables easy transport and installation. These skidded systems can operate independently or be combined to form larger systems or completely portable, modular process plants. Unlike traditional construction methods, which build structures from the ground up on a construction site, these modular systems are built within a controlled environment, such as a fabrication shop. 

This process allows on-site construction and modular fabrication to occur simultaneously, providing several potential advantages, such as fewer onsite disruptions and less risk, waste, and time spent on construction. Modular systems have also been shown to help reduce a capital project's environmental footprint.

Advantages of Modular Process Skid Design

Modular skids can be a flexible and scalable solution for some projects, helping to overcome common challenges such as limited manpower and concerns about safety, quality, and efficiency. When properly matched to the right projects, they can help with faster project completion, ease of expansion, and fewer site disruptions.

We’ve listed below the potential advantages of modular process systems:

  • Efficiency: Can reduce on-site construction time and costs.
  • Flexibility: Easily expandable and modifiable to meet future process needs.
  • Quality Control: Construction in a controlled environment can improve build quality.
  • Reduced Risk: Can minimize safety hazards and environmental impact during construction.
  • Speed: Enables parallel construction phases, helping to shorten project timelines.

Key Considerations in Modular Process Skid Design

The design and fabrication process of modular skid systems requires extensive front-end planning and material procurement. All design, procurement, integration, and logistical issues should be resolved before construction begins.

This approach ensures that materials and fabricated components are compatible, fit within the skidded system's frame, and are compatible with the systems they are intended to support. An early planning phase can help all stakeholders avoid costly modifications and delays during later stages of development in installation.

The following table summarizes important key aspects to consider below.

Modular Process Skid Design: Key Considerations

Aspect

Description

Project Scope and Requirements

Define the project's goals, capacity, and specifications while considering industry and environmental standards and modularization drivers and challenges.

Equipment and Material Selection and Sizing

Choose equipment and materials that meet performance needs and fit the modular design.

Piping and Instrumentation

Design for optimal fluid flow and process control, considering integration and accessibility.

Structural Design and Analysis

Ensure structural integrity, safety, and compliance with codes and standards.

Electrical and Control System Design

Integrate power supply, control systems, and instrumentation.

Safety and Environmental

Incorporate safety features and meet regulatory requirements for a safe, sustainable operation.

General Design Guidelines

To maximize accessibility, ensure integration with existing systems, and guarantee that the modular process system can adapt and change with your organization's operational needs over time without requiring significant rework. Modular process skid design requires careful layout planning and forward-thinking in the early phases of capital project planning. 

Steps in the Design and Engineering Process

Several essential phases are involved in modular process skid design and engineering, ranging from preliminary phases and detailed design and engineering to procurement and fabrication, assembly, and commissioning. Each step should be carried out by a qualified Engineering, Procurement, and Construction (EPC) professional with significant design-build experience to ensure that the final product meets industry standards and operational requirements. 

We’ve listed them below for further review. 

Modular Process Skid Design Steps

Conceptualization

Define project scope and initial design parameters.

Design Development

Detail designs, simulations, and models for integrity verification.

Equipment Selection

Choose equipment for functionality and compatibility.

System Integration

Ensure cohesive operation of all systems.

Fabrication & Assembly

Manufacture and assemble the skid in a controlled setting.

Testing

Conduct thorough tests to meet specifications.

Installation & Commissioning

Site delivery, installation, and operational readiness check.
