Built in Ontario.
Working everywhere.
One shipyard in North Glengarry, Ontario builds the steel. From there it trucks across Canada and the lower 48, rails to the western provinces and Alaska, and ships in containers to every export market that needs a barge a port crane can offload.
Overview
The barge that ships the way the contract demands.
Marine equipment used to be defined by the port that fabricated it. A barge built on the Mississippi worked the Mississippi; a barge built on the Tyne worked the North Sea. Sentinel sectional barges break that constraint at the source. Sections ship as oversized flatbed loads in North America, as standard freight (no permits) when you spec the Back Lake 8×20, by rail across the Canadian Shield, and disassembled inside ISO containers for any overseas job.
That shipping flexibility is what unlocks the geography. North American marine contractors are within trucking range of our shipyard for Standard sections. Mining and energy operators in remote inland regions get the same fleet by rail. Offshore wind developers in Europe and the US get feeder steel through ocean container freight. Same engineering, same documentation, same fleet — wherever the next job is.

Container-shipped capability worldwide.
We don't operate yards in these regions, but we ship sections by container, RoRo, and breakbulk to operators who do. Stamped engineering, ISO-format intermodal portability, and assembly with no welding or torque-controlled bolting are why we win export work.
North Sea & European Offshore Wind
Export capability for offshore wind feeder, cable-lay, and energy-island construction across Dutch, German, Danish, and UK waters.
Read →Latin American River Systems
Export capability for the Magdalena River, Orinoco Delta, and Amazon Basin oil & gas, dredging, and remote-logistics operators.
Read →West African Delta Operations
Export capability for the Niger Delta and surrounding region — modular refinery transport and shallow-draft crude logistics.

Tell us where the project is. We'll tell you how the steel arrives.
Send us the project location, the access road or rail spec at the staging point, the cargo or equipment you're floating, and your target NTP. We'll come back with a logistics plan — flatbed, rail, container, or RoRo — that lands the steel on time and within budget for your region.
