A modular skid package (also called a process skid or skid-mounted unit) is a pre-engineered, pre-fabricated, and pre-tested process system assembled on a structural steel baseframe — or "skid" — in a controlled workshop environment, then transported and installed as a complete unit at the project site.

Unlike traditional field-constructed systems where piping, equipment, and instrumentation are installed piece-by-piece on-site, modular skids are fully assembled, piped, wired, and tested before delivery. This fundamental difference delivers several measurable advantages:

• Reduced Installation Time: Site work is reduced to connection of utilities and anchor bolt installation, cutting field man-hours by 40–70%.
• Superior Quality Control: Workshop conditions allow controlled welding, pressure testing, and instrumentation calibration under consistent conditions.
• Lower Total Project Cost: Shop labor is typically less expensive than field labor; rework and punch-list items are minimized.
• Parallel Engineering & Manufacturing: Skids can be fabricated while civil foundations are still being constructed on-site, compressing the overall project schedule.

RMI specializes in customized skid packages — including Chemical Injection Skids, Pump Skids, Valve Skids, and Pressure Vessel Skids — for Oil & Gas, Petrochemical, Power, New Energy, and Environmental industries worldwide.

Modular process design is an engineering methodology in which a complex industrial process plant is divided into discrete, self-contained functional modules — each fully assembled, tested, and ready to integrate. These modules can be chemical injection units, pumping systems, metering stations, filtration packages, pressure let-down systems, or any other process function.

Modern EPC contractors and plant operators favor modularization for the following reasons:

• Scalability & Flexibility: Additional capacity can be achieved by adding identical modules without redesigning the entire plant.
• Repeatability: Proven module designs can be replicated across multiple project sites, reducing engineering effort and risk.
• Remote & Harsh Environment Suitability: Modules shipped to offshore platforms, Arctic sites, or remote locations minimize the skilled labor needed in difficult environments.
• Faster Commissioning: Pre-commissioned modules shorten on-site startup time and reduce commissioning risk.
• Risk Mitigation: Factory Acceptance Tests (FAT) identify issues before shipping, eliminating costly late-stage field changes.

At RMI, every skid and modular package undergoes rigorous Factory Acceptance Testing (FAT) before delivery, ensuring seamless integration at the project site — whether in Europe, the Middle East, Southeast Asia, or beyond.

RMI manufactures a comprehensive range of skid-mounted process packages, including:

• Chemical Injection Skids — Methanol injection, scale inhibitor, corrosion inhibitor, biocide, and demulsifier dosing packages for oil & gas pipelines and wellheads.
• Pump Skids — Centrifugal and reciprocating pump packages with integrated piping, instrumentation, and controls.
• Valve Skids & Manifolds — Multi-port valve manifolds, choke valve packages, and wellhead control panels.
• Pressure Vessel Skids — Separator, filter, and vessel skids for liquid/gas processing applications.
• Metering & Sampling Skids — Custody transfer measurement packages for hydrocarbon and water flow.

Industries served include: Oil & Gas, Petrochemical, Power Generation, Marine & Offshore, New Energy (Hydrogen, LNG), Mining, and Environmental Protection. RMI has delivered skid packages to clients in over 50 countries, with certifications including ASME, API, EU/PED, AD2000, Norsok, and BV Marine.

Standard off-the-shelf equipment rarely matches the exact process conditions, footprint constraints, or material requirements of a specific project. A custom skid solution is engineered specifically to your process parameters, resulting in:

• Exact Process Fit: Flow rates, pressures, temperatures, fluid compositions, and turndown ratios are matched to your specific operating conditions.
• Footprint Optimization: The skid is designed to fit the available space — critical for offshore topsides, FPSOs, or compact plant areas.
• Material Compatibility: Correct alloy selection (duplex stainless, Inconel, titanium, etc.) for corrosive or high-temperature service prevents premature failure.
• Single-Source Responsibility: One supplier manages engineering, procurement, fabrication, and testing — eliminating interface management problems.
• Long-Term Support: RMI provides documentation packages (P&IDs, as-built drawings, material certificates, test reports) that support plant operations and future maintenance.

With over 10 years of experience and 500+ completed projects, RMI has the technical expertise and manufacturing capacity to deliver complex customized skid packages to the most demanding international standards.

Quality and compliance are central to every RMI project. Our fabrication and design capabilities are backed by internationally recognized certifications:

• ASME U & S Stamp — Pressure vessel and pressure piping design and fabrication per ASME Boiler and Pressure Vessel Code.
• API Standards — Compliance with API 610 (pumps), API 6D (valves), and API 14E (piping) where applicable.
• EU/PED (Pressure Equipment Directive) — For projects supplying equipment to European clients and EPC contractors.
• AD2000 (German Pressure Vessel Regulations) — For European and Middle Eastern project specifications.
• Norsok Standards — For Norwegian offshore and subsea projects.
• JIS Standards — For Japanese clients and projects in Asia-Pacific.
• BV Marine — Bureau Veritas Marine classification for offshore and marine applications.

All fabrication is performed with full material traceability, certified welding procedures (WPS/PQR), and NDT (Non-Destructive Testing) including RT, UT, MT, and PT as required by project specifications.

RMI has extensive experience in international project delivery, having supplied skid packages and fabricated components to over 50 countries. Our export process includes:

• Pre-Shipment Inspection (PSI): Third-party inspection by TÜV, BV, Lloyd's, SGS, or client's own inspector is fully supported.
• Factory Acceptance Test (FAT): Full functional testing — pressure testing, leak testing, instrument loop checks — performed and documented before crating.
• Export Packing: Skids are cleaned, preserved, blanked, and packed in seaworthy wooden cases or on open-top flatracks per ISPM-15 phytosanitary standards.
• Documentation: Full export documentation including commercial invoice, packing list, certificate of origin, material test certificates (MTCs), and inspection release notes.
• Logistics Coordination: RMI can arrange FCL or LCL ocean freight, air freight for urgent parts, and inland transport — or work with your nominated freight forwarder.

Our location in Shanghai provides direct access to major international container ports, enabling efficient and cost-effective global shipping to any destination.
