Spud Barges: Spuds & Spud Wells

The steel that holds a construction barge on station in shallow water: box-section spuds with pointed tips, spud wells through the hull, A-frame gantries with sheaves, and securing pins.

Pinned to the seabed

In shallow water a barge does not need to jack up: it drops spuds through wells in its hull and pins itself in place.

Spuds

Box-section spuds fabricated from plate, with pointed tips that bite into the seabed.

A kit of parts

Spuds, wells, gantries and pins: every member numbered, match-marked and packed in erection sequence.

Why Allmarc

Experience you can trust.

We fabricate to your drawings and prove the fit in our own bay before anything ships. Open any line for the detail.
