Build Your Own Dredger

We handle all the complex multidisciplinary engineering — fully assembled and factory tested. You build the steel hull at your local yard and fit everything together with our supervision. Standard welding, major savings.

Dredge Yard supply parts — complete skid assembly with pump, hydraulics, control panel and cutter components

STEP 1

We Deliver — Complete Machinery Package

We handle everything that requires complex multidisciplinary engineering — pump drive, hydraulics, cutter mechanics, automation — fully assembled and factory-tested as one complete skid arrangement.

Dredge pump, drive train, spud hoisting system & complete hydraulic system with piping
Cutter unit, turning points, winch skid & gantry sheave blocks
Control panel, electrical systems & automation
Fully assembled, factory tested & container transportable

STEP 2

You Build — Steel Structures

Using our detailed engineering drawings, your local shipyard builds the hull and structural steelwork. This is all standard plate construction and welding — no specialized dredger expertise needed.

Pontoon hulls — standard steel plate welding
Cutter ladder, A-frame & suction pipe structures
Complete engineering drawings & material list provided
Build locally — significantly reduce labour & logistics costs

Pontoon hull internal framework — stiffeners and structural steelwork by shipyard

Completed pontoon hull exterior — standard steel plate construction

Skid assembly being placed into pontoon hull

Main pontoon sub-assembly — Dredge Yard components connecting to hull

Deck components assembled on main pontoon

Cutter unit, turning points and gantry sheave blocks — assembled by Dredge Yard

Complete assembled CSD 500 dredger — all systems connected

STEP 3

Assemble — Connect & Launch

With our engineers on site for supervision, your team fits the machinery into the hull, routes the wiring, and connects all systems. Then it's time to launch.

Place skid into pontoons & weld into position
Route wiring through hull & cutter ladder
Connect all systems — Dredge Yard supervision on site
Commission, test & launch your dredger
