America’s Escort Tug Buildout Is Getting Serious
The launch of Titan, a 90+ tonne bollard-pull escort tug for Suderman & Young, is the newest piece of a much larger story: U.S. operators are putting more horsepower, more escort capability and more sophisticated vessels alongside a merchant fleet that keeps getting bigger.
Anyone who has spent time around ship-assist work knows the tug market usually changes quietly. Operators do not replace good iron just because a new design looks impressive at a boat show. They spend when the job changes. And right now the job is changing. Bigger ships, busier channels, LNG terminals, tighter emissions requirements and more demanding escort work are pushing a noticeable group of U.S. tug programs toward higher power and more capability. The latest evidence hit the water on September 28 in Coden, Alabama.
Titan puts the 90-tonne escort class back in the spotlight
Master Boat Builders has launched Titan for Suderman & Young Towing Company. The Robert Allan-designed RApport 3000 escort tug is the third vessel in a four-tug program and is built squarely for demanding harbor, ship-assist and escort service.
This is no longer just a one-boat story.
Titan arrives in the same year that Suderman & Young received Saturn, the first RApport 3000 in its four-vessel program. Master Boat Builders has also delivered the 90+ tonne Barbara G to Bay-Houston Towing, while McAllister has just taken delivery of the 84-tonne Mary McAllister.
Different owners have different missions, but the clustering is important: several major U.S. operators are adding high-output tractor and escort tugs at roughly the same time.
The important number is not 90 tonnes by itself. There is no universal “correct” bollard pull for a modern tug. What matters is that 90+ tonnes is appearing repeatedly in new U.S. escort programs where ship size, terminal risk and maneuvering demands justify it.
Four programs show how quickly the fleet picture is moving
| Vessel / Program | Operator / Owner | Bollard Pull | Power | Mission | Latest Development |
|---|---|---|---|---|---|
| Titan RApport 3000 |
Suderman & Young | 90+ t | 7,000 hp | Escort / ship assist / harbor | Launched Sep. 28, 2026 |
| Barbara G RApport 3000 |
Bay-Houston Towing / G&H Towing | 90+ t | 7,000 hp | Texas Gulf Coast escort and ship assist | Delivered Sep. 2026 |
| Mary McAllister Tier IV |
McAllister Towing | 84 t | 6,770 hp | Escort / towing / FiFi 1 | Delivered Sep. 2026 |
| Hulls 11 & 12 ICE |
Great Lakes Towing | ≈30 t | 2,000 hp | Great Lakes harbor / ice service | Ordered Sep. 2026 |
The Great Lakes order is especially useful context. Its new Damen Stan Tug 1907 ICE vessels are dramatically smaller than the Gulf escort tugs because the mission is different. That is the point: the tug market is not simply chasing horsepower. Operators are becoming more deliberate about matching hull form, bollard pull, propulsion, emissions and deck machinery to a specific operating profile.
Houston explains why more escort capability is attractive
The clearest explanation for the Gulf Coast buildout may be sitting in the traffic data. Port Houston’s September market report shows a channel handling more tonnage and more vessel movements even before the region’s next major wave of energy infrastructure fully arrives.
Bigger ships already fit the picture
Port Houston says Bayport can receive ships in the 15,000–17,000 TEU range, matching the container-vessel capacity that can transit the expanded Panama Canal.
Port Everglades is seeing the same size pressure
In August, the 13,050-TEU MSC Vandya became the largest cargo ship to call the port, but water-depth restrictions required the vessel to arrive lightly loaded.
None of this proves that every port needs 90 tonnes of pull. It does show why operators serving major gateways are thinking ahead. Vessel length, windage, displacement, channel geometry, stopping distance and terminal-specific escort requirements can all raise the value of additional steering and braking capability.
The tug is becoming a more specialized piece of port infrastructure
Power is moving upward
The newest Gulf escort vessels are carrying bollard-pull figures that would have put them firmly at the upper end of routine harbor-tug fleets not many years ago.
Escort capability matters more
Bollard pull is only part of the equation. Hull design, indirect steering force, winches, propulsion response and line handling increasingly define the vessel’s value.
Low emissions are entering the spec sheet
Mary McAllister uses EPA Tier IV Caterpillar engines, while Barbara G is reported with Tier 4-compliant machinery and exhaust aftertreatment.
Louisiana LNG shows where the tug market may be heading next
The most important tug program that has not yet delivered a boat may be unfolding in Louisiana. Green Tug Towing — the Saltchuk Marine and Harbor Docking & Towing joint venture — has a long-term contract to provide towage services for Woodside Energy’s Louisiana LNG development.
Four new RApport 2800H tugs. Twenty years of service.
C&C Marine and Repair in Belle Chasse is constructing four diesel-electric hybrid escort tugs for the project. The vessels are scheduled for delivery in 2028, ahead of Woodside’s targeted first LNG production in 2029.
The broader services award is valued at more than $300 million. The tugs are intended to handle LNG carrier berthing, unberthing, escort, standby and emergency response.
C&C said the Green Tug Towing vessels joined another four hybrid escort tugs already under construction, bringing its active tug program at the yard to eight vessels. For equipment suppliers, naval architects and shipyards, that is a more consequential signal than any single launch.
How quickly the pieces have accumulated
The first RApport 3000 in Suderman & Young’s four-vessel program is launched.
Four RApport 2800H vessels begin taking shape at C&C Marine and Repair.
The 90+ tonne escort-tug series moves from shipyard program to active fleet.
Another 90+ tonne RApport 3000 joins the Texas Gulf Coast tug fleet.
An 84-tonne, 6,770-hp Tier IV tractor tug joins McAllister’s fleet.
Fleet renewal continues with two mission-specific ice-capable harbor tugs.
The third RApport 3000 in Suderman & Young’s four-tug series reaches the water.
This is bigger than one U.S. shipyard
Industry data cited by Maritime Journal showed 177 port tugs and river vessels delivered globally in the first half of 2026, extending the rise seen during 2024 and 2025.
At the same time, operators around the world are experimenting with battery-electric, hybrid and methanol propulsion while continuing to order conventional high-output diesel tugs.
That split is worth watching. The next generation of tugboats is not converging on one propulsion system. It is converging on a broader idea: fit-for-purpose vessels with enough power, maneuverability, redundancy and emissions performance for a specific contract.
Five things tug operators and suppliers should watch through 2027
Does 80–90+ tonnes spread beyond major terminals?
Watch whether the current high-power escort programs remain concentrated around container, tanker and LNG work or start becoming more common in ordinary harbor renewal programs.
Can hybrid systems justify themselves operationally?
Tug duty cycles include large amounts of standby and low-load operation, creating a logical use case for hybridization. Actual fuel savings and maintenance experience will matter more than brochure numbers.
Winches and lines become part of the power story
Additional propulsion capability only matters when towing gear, render/recover systems, fendering and line handling are engineered for the loads and operating profile.
Long contracts can unlock purpose-built fleets
Woodside’s 20-year Louisiana LNG arrangement demonstrates how long-duration service contracts can support significant capital investment in specialized newbuilds.
Multi-vessel programs matter
Master Boat Builders, C&C Marine, Washburn & Doughty and Great Lakes Shipyard are all executing multi-vessel tug programs. Build slots and repeat-series efficiency deserve attention.
Do not confuse horsepower with productivity
A larger tug is not automatically a better tug. Utilization, crewing, fuel burn, berth geometry, maintenance and contract requirements ultimately determine whether extra capability earns a return.
