Overview

The full dredging fleet, from one shop.

Dredging is a multi-vessel operation. The dredge needs a deck to work off. The spoils have to go somewhere: hoppers, scows, or pumped discharge to a disposal area. Crews and fuel need a tender that can stay on station for the duration. Every one of those vessels has to fit the project, the channel, the disposal cycle, and whatever the regulators are looking for that year.

Federal channel maintenance, private terminal deepening, contaminated-sediment remediation, routine harbor cleanup — every section ships with stamped drawings. The owner, the regulator, and your insurance carrier all want to see that paperwork. It's already in the box.

Applications

Where our barges fit in a dredging operation

Dredge platforms

The Standard 10×40 barge has a 36,000 lb evenly distributed deckload. Have the equipment loads and platform layout reviewed before use.

Hopper barges

The Standard 10×40 barge has a 36,000 lb evenly distributed deckload. Have the equipment loads and platform layout reviewed before use.

Tender floats

Standard sections for crew, fuel, parts, and small tools during long campaigns far from a maintenance dock.

Pipeline floats

Sectional supports for hydraulic discharge pipe crossing open water to upland disposal.

Sediment containment

Bull-railed sections form short-term containment cells for storage and dewatering before final disposal.

Survey & monitoring

Standard sections platform hydrographic gear, sampling crews, and turbidity monitoring equipment.

Why sectional

Modular floats keep dredge schedules honest.

Dredge schedules don't forgive much. Federal channel windows are short. Environmental permits often have tight in-water work seasons. Private terminal owners want their berths back on a fixed date. The last thing you need on day one of a 90-day campaign is a platform shortage or the wrong-size float.

Sectional fixes the sizing problem at the front end. Four sections for a small private dredge, twelve for a mid-size federal job, twenty for a major capital deepening — the same fleet scales up and back down across the season. Finish a dredge job on Friday and start a pier job two weeks later? The same sections re-couple into a bridge work platform. No modification.

For spoils, hopper boxes are available as an option. Tell us the material, production rate and disposal cycle and the hopper is sized and priced with your quote.

Spec guide

Sizing your dredge fleet.

Start with the dredge spec. A small clamshell on a 30-ton crane needs a different platform than a 12-inch hydraulic cutter with internal spuds and a generator package. Tell us what you're running, what your bucket or production rate is, what depth you're cutting to, and what current and tide you're up against. We'll size the platform from there.

For environmental dredging, where contaminated sediment has to be contained and turbidity has to stay down, tell us the containment requirements with your quote request so the hopper and deck configuration can be confirmed in writing. Talk to us early — the environmental spec usually drives the most expensive part of the float package, and getting it right at the bid stage saves real money over the campaign.

Spec it for your job

Spec a dredge-support and hopper fleet.

Send your dredge spec — clamshell, mechanical bucket, or hydraulic cutter — plus production rate, cut depth, current, and disposal cycle. We'll size the platform, the spuds, and the hopper count against your campaign and confirm bull-rail vs dedicated hopper economics for your spoil volumes.

Questions

Dredging FAQ

Pricing, specs, lead times, and delivery — straight answers.

How much spoil does a hopper barge carry?
It depends on the hopper box and the Standard barge it sits on, and deck load stays within the barge rating. Tell us your production rate and the hopper is sized with your quote.
Can I run a hydraulic cutter dredge from a Sentinel barge?
The Standard 10×40 barge has a 36,000 lb evenly distributed deckload. Have the equipment loads and platform layout reviewed before use.
Are sectional barges OK for environmental dredging?
Hopper boxes are available as an option. Send the containment and turbidity requirements with your quote request and we will confirm what can be built.
Will the dredge platform stay on station in current?
The Standard 10×40 barge has a 36,000 lb evenly distributed deckload. Have the equipment loads and platform layout reviewed before use.
Can the same fleet do dredge support and bridge work?
The Standard 10×40 barge has a 36,000 lb evenly distributed deckload. Have the equipment loads and platform layout reviewed before use.
