Compressor Package & Gas Compression Equipment Transport

Compressor Package Transport from R&RM LLC

Gas compressor packages are among the most demanding oversize and overweight freight categories in the oil and gas and industrial sectors. A single large reciprocating compressor unit — with its engine or motor driver, skid frame, coolers, scrubbers, suction and discharge piping, and control panel — can span 50 to 70 feet, reach 12 to 16 feet in width, and weigh 80,000 to 200,000 pounds or more. Centrifugal compressor trains for pipeline service often ship as modular packages on multiple loads with coordinated delivery sequencing. Gas processing skids incorporating compressors, separators, heat exchangers, and instrumentation are routinely among the widest and heaviest loads moving on the nation's highway system.

R&RM LLC has been transporting oversize and overweight industrial equipment since 2011, operating out of Cumming, Georgia and providing service to all 48 continental states. We haul compressor packages from fabrication shops and equipment yards to well pads, gas gathering facilities, compressor stations, LNG plants, and industrial process facilities — with full permit coordination, route planning, and pilot car arrangement on every move. Our experience with oil and gas industry logistics means we understand the schedule pressures and remote delivery challenges that come with moving compression equipment to active field locations.

Types of Compressor Equipment We Transport

Reciprocating Compressor Packages

Reciprocating compressor packages are the workhorse of natural gas gathering, production compression, and gas lift service. These units typically pair a large natural gas engine — Caterpillar, Ariel, Waukesha, or Dresser-Rand frames are common — with a reciprocating compressor running one to six or more throws on a single crankshaft frame. The complete package, built on a structural steel skid with a weather enclosure, can range from a 200-horsepower single-stage wellhead unit at 15,000 to 25,000 pounds to a 2,000-horsepower, six-throw gathering station compressor at 100,000 to 150,000 pounds complete on its skid.

The primary transport challenges for reciprocating packages are weight — many units require multi-axle lowboy or RGN trailers to stay within bridge formula axle weight limits — and width. Large packages with cooler bundles or weather enclosures commonly extend to 14 or 16 feet wide, requiring overwidth permits and pilot car escorts. We transport reciprocating compressor packages on multi-axle RGN and lowboy trailers with complete permit packages for width, weight, and in some cases height and length.

Centrifugal Compressor Packages and Modules

Centrifugal compressor packages for pipeline transmission, gas processing, and re-injection service are typically heavier, taller, and often more dimensionally complex than reciprocating units. A large pipeline centrifugal compressor train — with its gas turbine or electric motor driver, compressor casing, coupling, gearbox, and associated lube oil and seal gas console — can weigh 200,000 to 400,000 pounds complete on a single installation skid and require hydraulic platform trailers, route engineering, and superload permits for transport.

When centrifugal compressor packages are too large for a single load, they are factory-modularized for multi-load transport. Compressor cases, driver units, cooler modules, and auxiliary skids ship as separate loads and are assembled at the installation site. We coordinate multi-load compressor station deliveries with staged arrivals that match the mechanical installation sequence to minimize staging area requirements at remote field locations.

Gas Gathering Skids and Wellhead Compression Units

Smaller wellhead compression and low-pressure gas gathering skids — 50 to 500 horsepower in most cases — are among the most frequently transported compressor types in active shale plays. These packages are built in standard configurations by compressor rental companies and independents, typically on 8-foot-wide skids within legal load limits, though heavier units still require overweight permits for axle weight compliance. Rapid deployment from equipment yards to new well pads on short notice is common in gathering system buildout work. We provide prompt turnaround on standard wellhead compression quotes for operators working on tight completion schedules.

Refrigeration and Process Compression Skids

Refrigeration compression skids for NGL extraction, LNG production, ethylene plants, and industrial cooling applications frequently appear as large, oversize loads. Propane refrigeration compressor skids for gas processing plants — running on electric motors or natural gas engines with integrated heat exchangers, scrubbers, and piping headers on the skid — routinely reach 50 to 70 feet in length, 12 to 16 feet in width, and 80,000 to 150,000 pounds loaded. These units require RGN or lowboy trailers with 9 to 13 axles, multi-state permit packages, and pilot cars.

Large industrial refrigeration compressor packages for food processing, cold storage, ammonia refrigeration, and industrial gas production share similar transport characteristics and requirements. We handle refrigeration compression skids for both the oil and gas sector and industrial refrigeration applications.

Air Compression and Instrument Air Packages

Large centrifugal or reciprocating air compressors for industrial plant service, pipeline air start systems, and instrument air supply — packaged on structural steel skids with aftercoolers, dryers, and air receivers — move as oversize loads when the package weight exceeds 80,000 pounds gross vehicle weight. Skid-mounted industrial air compressor packages for large refinery or petrochemical plant installations can reach 30,000 to 60,000 pounds and 40 to 60 feet in length, requiring overweight permits and sometimes overwidth clearances for equipment projecting beyond the skid frame. We transport industrial air compression packages on flatbed and step-deck trailers with the permit package appropriate for the load dimensions.

Compressor Station Modules and Building Units

Prefabricated compressor station buildings and modules — including control rooms, electric switchgear buildings, battery backup rooms, and utility modules for pipeline compressor station projects — move as oversize and overwidth loads when complete. Steel-framed building modules for pipeline compressor stations can be 20 to 40 feet long, 14 to 20 feet wide, and 14 to 18 feet tall, requiring RGN trailers (for height reduction at the trailer deck), overwidth permits, and height permits with route surveys for low bridge and overhead utility clearances. We transport compressor station building and module packages on RGN trailers with full permit packages and can coordinate multi-load station project deliveries.

Oversize Permit Requirements for Compressor Packages

Compressor packages routinely require all four types of oversize permits simultaneously: overweight (for skid weight plus trailer and tractor), overwidth (for cooling bundles and enclosures), overlength (for large packages on low-boy trailers), and overheight (when package height plus trailer deck exceeds 13 feet 6 inches legal limit). Multi-state moves through the producing regions of the Appalachian Basin, Permian Basin, Haynesville, Eagle Ford, and Marcellus often involve permit coordination across four to six states for a single move.

Our permit services team handles axle weight calculations, bridge formula compliance, and multi-state permit filings for compressor package shipments. For superload-class centrifugal compressor trains — loads exceeding 200,000 pounds gross vehicle weight or requiring hydraulic platform trailers — we begin the permit process at booking to account for state permit agency processing times, which can range from a few days to several weeks depending on the state and load dimensions. See our superload permits guide and multi-state permit coordination guide for detail on the process.

Industries and Applications We Serve

Oil and Gas Production and Gathering

Natural gas producers, midstream gathering companies, and oil field service firms are the largest users of compressor package transport. From initial wellhead compression on newly completed production wells through high-pressure gathering system booster stations and reinjection compressors at enhanced recovery projects, we serve the full range of oil and gas compression transport needs. We have extensive experience delivering compression equipment to remote well pad locations with limited road access, coordinating county road weight restriction permits and temporary road reinforcement where needed for project deliveries to active field areas in Texas, Pennsylvania, West Virginia, Colorado, Wyoming, Oklahoma, and across the Permian, Marcellus, Utica, Haynesville, and DJ Basin plays.

Natural Gas Pipeline Transmission

Interstate natural gas pipeline companies operate compressor stations every 50 to 100 miles along their systems, maintaining pipeline pressure to move gas from production areas to market. When pipeline compressors require replacement or new stations are constructed, the primary compressor units — gas turbine or electric motor driven centrifugal compressors on large transmission lines — are among the largest and heaviest loads that move on the highway system. We transport pipeline compressor units with the multi-axle trailer configurations, superload permits, and route engineering these projects require.

Gas Processing Plants and NGL Fractionation

Gas processing plant projects — including new NGL extraction facilities, plant expansions, and refrigeration unit replacements — generate multiple large compressor package moves on a single project. Inlet compression, lean oil absorption compressors, residue gas compressors, and refrigeration compression units for a new processing plant can involve four to eight separate oversize truckloads of compressor equipment, often sequenced over weeks or months as the project progresses through installation phases. We handle coordinated multi-load gas plant compressor delivery programs and maintain communication with project managers on delivery scheduling and sequencing.

LNG Production and Storage Facilities

Small-scale and peak-shave LNG facilities use large refrigeration compressor packages — propane pre-cool, methane refrigeration, or mixed refrigerant cycles — that are among the largest oversize loads in the gas processing sector. New LNG export facility construction and small-scale liquefaction projects at gas wells, landfills, and stranded gas locations all require heavy haul transport for the compressor and heat exchanger equipment at the core of the liquefaction process. We have experience with LNG project equipment deliveries in the Gulf Coast, Appalachian, and Rocky Mountain production regions.

Industrial Gas Compression

Industrial gas companies — producing oxygen, nitrogen, hydrogen, carbon dioxide, and other gases for industrial and medical markets — use large centrifugal and reciprocating compressors in their separation, liquefaction, and distribution facilities. Reciprocating compressor packages for high-pressure hydrogen compression and centrifugal compressors for air separation units can be substantial oversize loads. We transport industrial gas compression equipment from equipment manufacturers, repair facilities, and exchange programs to plant locations across all 48 states.

Loading, Blocking, and Transport Considerations

Large compressor packages require careful attention to blocking, cribbing, and tie-down to protect precision rotating equipment, fragile instrumentation, and pressure-rated piping during highway transport. Key considerations include:

• Confirming cribbing and support points with the fabricator — compressor skid cross-members and lifting lugs are the correct support points; never support a skid from pressure vessel shells, cooler headers, or instrument tubing.
• Securing weather enclosure panels and doors to prevent wind damage and road vibration loosening at highway speeds.
• Protecting exposed compressor shaft ends, coupling guards, and valve operators with padding during transport.
• Verifying that suction and discharge nozzle flanges and pipe connections are blanked and protected for transit if inter-connecting piping is removed for the move.
• Confirming with the fabricator whether crankshaft, main bearings, or other rotating elements require shipping brackets or supports for road transport to prevent false brinelling from road vibration.

For multi-load compressor station deliveries, we confirm the delivery sequence with the project mechanical superintendent and coordinate arrivals to avoid staging congestion at active job sites. Large compressor station projects often have limited lay-down area and strict delivery windows to avoid interfering with civil and electrical work on the same site.

Trailer Types for Compressor Package Transport

The trailer type required for a compressor package depends primarily on the load weight and height:

• Flatbed (48–53 ft): Suitable for smaller compressor packages within legal width and weight limits. Legal length, 8.5 feet wide, 13.5 feet loaded height maximum, up to 48,000 pounds payload on a standard flatbed.
• Step-deck (48–53 ft): Upper deck reduces the working height for equipment that fits legal weight limits but needs the lower deck height to stay within 13.5 feet overall. Common for medium-sized wellhead compression packages.
• Removable gooseneck (RGN) lowboy: The primary trailer type for large overweight compressor packages. Three-axle to nine-axle configurations available; deck height 18 to 24 inches, allowing tall packages to stay within or near legal height with overheight permits. Most large reciprocating and centrifugal compressor packages move on 5- to 9-axle RGN trailers.
• Hydraulic platform / multi-axle modular: Required for superload-class centrifugal compressor units exceeding 200,000 pounds. These trailers allow axle count to be configured precisely for bridge formula compliance at maximum gross weights.

Pricing and Quoting for Compressor Package Transport

Compressor package transport pricing depends on the load weight, dimensions, and delivery distance, as well as trailer type, permit fees, pilot car costs, and any special access requirements for remote delivery locations. Standard wellhead compression packages on flatbed trailers within a single state can be quoted quickly. Large reciprocating packages requiring RGN trailers and multi-state permits benefit from a detailed quote based on the specific load dimensions and origin-destination route. Superload-class centrifugal packages require route engineering and a custom permit program as part of the quote.
