Inland marine

Barge tracking software for inland waterway operators who need the fleet in one picture

Inland waterway barge transport is the movement of bulk cargo on rivers and canals by unpowered barges pushed in a tow by a towing vessel. A standard dry cargo hopper runs roughly 195 feet by 35 feet and carries about 1,500 tons, and a towboat may push 15 or more at once through chambers measuring 600 feet by 110 feet. Neurobird holds barge position, commodity, status and the timestamps that freight and demurrage turn on.

The daily reality

What barge line operators and inland towing companies actually deal with

Barge location lives in a dispatcher's head, a phone call to the fleet, and a spreadsheet that is right until the tow is rebuilt.
Demurrage and freight both depend on timestamps nobody records consistently: arrival, made into tow, delivered, released.
Subchapter M survey dates, certificates and vessel records sit in a binder on the boat rather than anywhere the office can see.

Why it stays broken

The fleet is spread over hundreds of river miles and the record of it is a phone call. Marine software was built for blue water vessels carrying containers, not for 1,500 ton hoppers that get rebuilt into a new tow twice a week.

One barge logged at the wrong fleet is a 600 foot chamber booked for the wrong tow.

What it does

Neurobird Barge Inland Waterway Audit Platform

Treat the barge as the unit of record, not the boat. Position, commodity, draft and status follow the hull no matter which tow it is in this week.

  • 1Track every barge by position, commodity, draft and status without calling the fleet
  • 2Record the timestamps that freight and demurrage actually turn on
  • 3Keep vessel certificates, survey dates and Subchapter M records visible from the office
  • 4Rebuild a tow on paper before the boat rebuilds it on the river

What changes with Neurobird Barge Inland Waterway?

The same work, read left to right: how it runs today, and how it runs once the record is in one place.

Who is this for?

Same river, three different operating models.

Owner operator

You run 1 boat and a handful of barges

You dispatch, you bill, you keep the vessel file. You need the 1,500 ton hopper and the survey date in the same place.

Barge line

You move freight for shippers

Freight and demurrage both turn on timestamps. You need them recorded at the event, not remembered at month end.

Fleeting and harbor service

You hold other people's barges

Hulls arrive, sit and leave under different accounts. You need a register that survives a tow being rebuilt.

How inland towing is actually regulated

Useful if you are entering the trade or preparing for a survey. Each source links out.

136 to 144

Subchapter M, the Coast Guard towing vessel inspection regime, spans 46 CFR Parts 136 through 144 and sets certification, safety management and recordkeeping duties.

Part 136

Certification requirements, including the certificate of inspection every inspected towing vessel must carry and keep current.

Part 140

Operations requirements: watchstanding, navigation safety and the vessel records a towing vessel has to produce on demand.

How does Neurobird Barge Inland Waterway work?

  1. Track the hull, not the tow

    Every barge carries its own record: commodity, tons, draft, position and status. Tows are assembled from hulls, not the other way round.

  2. Record the timestamps once

    Arrival, loaded, made into tow, delivered and released are captured at the event, so freight and demurrage are calculated rather than reconstructed.

  3. Keep the vessel file visible

    Certificates of inspection, survey dates and Subchapter M records live where the office can see them, not in a binder 400 miles downriver.

Barge inland waterway software questions, answered

Key terms

What is inland waterway barge transport?
Inland waterway barge transport is the movement of bulk cargo on rivers and canals by unpowered barges pushed in a tow by a towing vessel. A standard dry cargo hopper barge runs about 195 feet by 35 feet and carries roughly 1,500 tons, and a single towboat may push 15 or more of them at once.
What is Subchapter M?
Subchapter M is the Coast Guard inspection regime for towing vessels at 46 CFR Parts 136 through 144. It requires a certificate of inspection and either annual Coast Guard inspection or an approved towing safety management system audited by a third party, with vessel records kept current and available.

Why do locks matter so much to scheduling?

Because chamber size sets the shape of the day. A typical main chamber on the inland system is 600 feet by 110 feet, so a 15 barge tow has to be broken and double locked, and a queue at a single lock reorders every delivery behind it.

What timestamps actually drive money on a barge move?

Arrival at the loading dock, completion of loading, made into tow, arrival at destination, and release. Freight, demurrage and barge hire all key off those, and they are the ones most often recorded late or not at all.

Does this replace our accounting or ETA system?

No. It holds the operational truth: barge position, commodity, draft, status and timestamps. Whatever you use for invoicing reads from it rather than being retyped into.

Why we are building this

Inland towing moves enormous tonnage on very thin margins, and most of the operating record is verbal. Where a hull is, what is in it, when it arrived: all of that gets passed by radio and written on paper.

Subchapter M added a real compliance obligation on top of that, with certificates and survey dates and audits, and the answer for many operators was another binder.

We would rather build this with people who have stood a watch or worked a dispatch desk. Tell us how your fleet gets tracked, and where we have got it wrong.
