Sectional barge
vs spud barge.
They're not opposites. A sectional barge describes how the platform is built — modules pinned together. A spud barge describes what it does — holds station with vertical spuds. Most marine contractors run sectional spud barges that do both.
The confusion comes from product-category language: brochures talk about "sectional barges" and "spud barges" as if they're different products. They're different attributes of the same product. A sectional barge can be a spud barge. A spud barge is almost always sectional. The question isn't which type — it's which sections to pin together.
The right way to think about it
Sectional describes the construction method. Sectional barges are built from interchangeable steel modules that pin together on site into any rectangular deck. Spud barges are platforms that hold station with vertical steel piles (spuds) dropped through wells in the deck.
To build a sectional spud barge, you pin Heavy Duty 10×40×7 sections with integrated spud wells at the work end of the barge and standard 10×40 sections at the back for material, equipment, and tow.
A typical spec
- 2× Heavy Duty 10×40×7 sections with spud wells — these carry the crane, hammer, or dredge and host the spuds.
- 2–4× standard 10×40 sections pinned aft for material storage, fuel, generator, and crew access.
- Optional rake section at the bow for tow drag reduction during repositioning between work cells.
Pin those together with the pin-flange system and you have a 40–60 ft long spud platform that doubles as a general work barge between station-keeping jobs.

Sectional vs spud — common questions
Direct answers about heavy deck barges, charter terms, and global delivery.
- It can be. A sectional barge is defined by how it's built (modules pinned or bolted together). A spud barge is defined by what it does (holds station with vertical spuds). Most modern spud barges in marine contracting are sectional barges with spud wells in the Heavy Duty deck sections.
- A standard sectional deck is rated for material storage, light equipment, and tow loads. A spud barge needs Heavy Duty sections — thicker plate, deeper stiffener pack, integrated spud wells — to handle hammer reaction, crane picks, and the horizontal loads spuds transfer back into the hull.
- Not easily. The spud wells need to be engineered into the section structurally. Sentinel integrates spud wells into the 10×40×7 Heavy Duty section at fabrication. Adding wells to a section that wasn't built for them isn't recommended — the load path through the hull won't be correct.
- Mix. A typical layout pins two Heavy Duty sections with spud wells at the work end of the barge and standard sections at the back for material and equipment storage. That gets you the spud platform where the load is and saves cost on the rest of the deck.
