Marine & Offshore Equipment Transport

Marine & Offshore Equipment Hauling

The marine and offshore industries move more equipment over land than most people realize. Dredges are broken down and trucked between waterways. Workboats are hauled between shipyards and marinas on trailers. Offshore platform components — from structural modules to subsea equipment — travel by road from fabrication yards to ports and staging areas. Dock machinery including ship loaders, traveling cranes, and harbor equipment regularly requires ground transport when relocating between port facilities.

R&RM LLC — based in Cumming, Georgia — has been handling specialized heavy haul transport since 2011. We serve industrial equipment transport clients in the marine, dredging, offshore, and port sectors across all 48 continental states. Our experience with wide and heavy loads, RGN trailer configurations, and multi-state permit coordination makes us a reliable choice for equipment that doesn't fit neatly into a standard freight category.

Marine Equipment Types We Transport

Workboats and Utility Vessels

Workboats — crew boats, survey vessels, utility vessels, and support craft up to approximately 100 feet in length — are frequently transported by road. Reasons for land transport include delivery from the builder to the launch site, repositioning between projects in different waterways, shipyard transport for dry-dock service, and auction or sale deliveries. Boats in this size range are transported on specialized marine transport trailers, heavy-duty step deck trailers, or custom cradle arrangements on RGN equipment.

Typical transport dimensions for workboats in the 40- to 80-foot range are 16 to 24 feet wide (beam plus cradle/bunker system) and 12 to 18 feet tall on trailer. These loads consistently require oversize permits in every state, two pilot cars, and careful route planning around low bridges and tight underpasses. Our permit team coordinates routes using routing software that identifies bridge and overhead utility clearance constraints before the move begins.

Dredge Equipment and Cutter Suction Dredges

Dredging equipment represents some of the most complex marine transport work on roads. Large cutter suction dredges and hydraulic dredges are typically disassembled into transportable components — pontoons, ladder sections, cutterhead assemblies, spud poles, pump modules, and deck machinery — for land transport. Each component may be an oversize load on its own.

Common dredge transport scenarios:

• Cutter suction dredge sections: Hull pontoons are typically 8–14 feet wide and 30–60 feet long. Transported on multi-axle lowboys or step deck trailers with extended permits for length. Individual pontoon sections may weigh 20,000 to 80,000 lbs.
• Ladder frames and cutter assemblies: The cutter ladder assembly of a medium-size suction dredge is commonly 40–60 feet long and 6–10 feet wide, requiring length permits and rear pilot car escorts in most states.
• Spud poles: Dredge spud poles — positioning anchors that penetrate the bottom — are long, heavy steel cylinders. Length permits and overhang flags are standard for spud transport.
• Booster pump stations: Floating booster stations are transported in sections, with each pump module section typically fitting on an RGN trailer.

Our dispatch team works directly with dredging contractors and equipment manufacturers to plan the disassembly sequence, trailer requirements, and permit package for each component before scheduling begins.

Floating Cranes and Crane Barges (Component Transport)

Floating cranes and crane barge components — boom sections, lattice luffing jibs, counterweight frames, and crane body assemblies — are transported by road when the crane is relocated between projects or requires shipyard service. Large crawler crane components used aboard marine crane vessels are the same equipment transported for land-based crane work, and R&RM LLC's experience with crane transport translates directly to floating crane component moves.

Boom sections for large marine cranes are commonly 10–14 feet wide and 60–100 feet long, requiring both width and length permits as well as appropriate overhang lighting. Counterweight frames and counterweight blocks — often 40,000 to 100,000+ lbs — may require multi-axle RGN or hydraulic platform trailer configurations for weight distribution.

Offshore Platform and Jacket Components

Offshore platform fabrication yards produce structural steel components, topside modules, jacket sections, and process equipment that must be trucked to port before seafloor installation or vessel loading. Common offshore component transport scenarios include:

• Topside modules: Process modules, utility modules, and wellhead structures are transported from fabrication yards to load-out ports. These modules are typically 12–20 feet wide, 14–20 feet tall, and can weigh several hundred thousand pounds — sometimes requiring hydraulic platform trailer configurations for the heaviest components.
• Subsea equipment: Subsea trees, manifolds, pipeline end terminations (PLETs), and rigid pipe spools are transported in protective frames from manufacturers to vessel load-out docks. Dimensions vary widely; most subsea equipment transports on standard flatbed or step deck trailers with custom cribbing.
• Structural steel sections: Jacket legs, cross-bracing trusses, and transition pieces from fabrication yards to marine terminals are common steel transport loads. Long members often require length permits and rear escorts.
• Anchor handling equipment: Chain lockers, anchor windlasses, mooring equipment, and dynamic positioning thrusters are transported from manufacturing facilities to shipyards or ports for installation on vessels.

Port and Terminal Equipment

Port facilities and marine terminals operate specialized heavy machinery that moves by road during installation, relocation, and major overhaul:

• Ship loaders and unloaders: Conveyor-fed ship loaders and grab-type unloaders are very large machines — 30 to 60 feet wide in transport configuration. Major components including boom sections, gantry frames, and machinery houses are transported separately.
• Reach stackers and container handlers: Large reach stackers used in port container yards are commonly 10–12 feet wide in transport position and weigh 90,000 to 120,000 lbs. They require oversize permits and are typically transported on RGN trailers.
• Mobile harbor cranes: Port mobile harbor cranes — Liebherr, Gottwald, Konecranes — are moved between port facilities on multi-axle self-propelled or towed configurations. Component transport includes boom sections, slewing rings, and machinery platform sections.
• Rubber-tired gantry (RTG) cranes: RTG cranes used in container yards can be 80–100 feet wide in operating position. For road transport, they are disassembled into the main gantry frame, legs, and spreader sections. Each transport section may be 20–40 feet wide, requiring superload or special permit provisions in many states.
• Dock levelers and roll-on/roll-off ramps: Large RoRo ramps and linkspan structures are transported from fabricators to marine terminals. These are typically oversized for width and length.

Dive Support and Subsea Construction Equipment

The subsea construction and intervention sector moves specialized equipment between projects:

• Saturation diving systems: Diving bells, saturation chambers, and dive control vans are transported on flatbed or step deck trailers when relocated between vessels or from overhaul facilities. Saturation systems are typically 8–12 feet wide and 10–14 feet tall.
• ROV containers and launch recovery systems: ISO-framed ROV containers transport on standard flatbeds. Large LARS (Launch and Recovery Systems) for heavy-duty ROVs are 10–14 feet wide and may require oversize permits.
• Survey and geotechnical equipment: Seabed sampling systems, geotechnical rigs, and CPT frames are transported to and from vessels on step deck trailers. Many are built in ISO container frames for compatibility.

Trailer Selection for Marine Equipment

RGN Trailers

The RGN is the standard trailer for wheeled or tracked marine equipment — workboats on cradles with axle systems, mobile harbor cranes, and reach stackers that can drive on under their own power or with hydraulic dollies. The low deck height of a 3-axle RGN is also advantageous for tall boat hulls — every inch of deck height reduction extends the height clearance margin for bridges and utility lines on the route.

Multi-Axle Lowboys and Hydraulic Platform Trailers

Very heavy offshore components — topside modules, heavy fabricated steel sections, large machinery foundations — require multi-axle lowboy or modular hydraulic trailer configurations. These trailers distribute load weight over many axles, allowing transport of components well above standard axle weight limits. Our dispatch team works with specialized hydraulic trailer operators for loads that exceed the capacity of standard 3- to 7-axle configurations.

Extended Deck and Long Combination Trailers

Long marine components — dredge ladder sections, structural steel members, boom sections — frequently require permits for length overhang, rear safety lighting, and rear pilot car escort. Extended deck trailers and jeep/booster combinations are used to achieve the required deck length while managing axle weight distribution within permit limits.

Oversize Permit Considerations for Marine Equipment

Marine and offshore equipment moves are among the most complex in terms of permit coordination. Key considerations include:

• Width permits: Most marine equipment exceeds 8 ft 6 in legal width, triggering oversize permits in every state on the route. Wide boat hulls, dredge pontoons, and port machinery can reach 20+ feet wide.
• Height permits: Tall loads — boat hulls on cradles, offshore modules — frequently exceed the 13 ft 6 in legal height. Route planning around bridge clearances is critical.
• Length permits: Long components — boom sections, dredge ladder frames, steel jacket members — frequently require length permits and overhang escort lighting.
• Weight permits: Heavy offshore components and large dredge sections may exceed the 80,000-lb GVW limit, requiring overweight permits and specific axle configuration approvals.
• Night hauling and travel windows: Many states restrict oversize movement to daylight hours. Very wide loads (over 14–16 ft) may be restricted to non-peak travel hours in some states. Our permit services team identifies and plans around these restrictions.

Marine Equipment Routes and Destination Markets

Marine and offshore equipment transport demand concentrates around key geographic markets:

• Gulf Coast: Louisiana, Texas, and Mississippi are the hub of offshore oil and gas equipment fabrication and deployment. Fabrication yards in Morgan City, Houma, Port Fourchon, and Corpus Christi regularly produce components for land transport to staging ports.
• Southeast port facilities: Georgia (Savannah, Brunswick), South Carolina (Charleston), and Florida (Port Everglades, Jacksonville) operate active marine terminals with regular need for dock equipment transport and vessel repositioning.
• Mid-Atlantic and Northeast: Virginia (Norfolk, Portsmouth), Maryland (Baltimore), and New York/New Jersey handle significant marine equipment movement, including naval vessel component transport and commercial port equipment.
• Pacific Coast: Washington and Oregon host shipbuilding and marine construction operations; California ports are major transit points for offshore equipment and vessel components.

R&RM LLC operates across all these corridors. Our familiarity with the permit requirements in Louisiana, Texas, Georgia, and across the Southeast is particularly relevant for Gulf Coast and East Coast marine transport moves.
