Understand the channel
Review access, water depth, working width, dredge reach and the amount and nature of material to be handled.

Excavate it.
Move it by water.
WHH configures floating excavator platforms, crane barges, hoppers and tugs to support dredging and move silt or dredged material through constrained inland-waterway sites.
A complete floating system
One operation.
Not one machine.
Dredging works when excavation, containment and material movement are planned as one continuous process.
WHH can configure the floating work platform at the dredge face, provide hopper capacity for the excavated material and plan the tug movements needed to cycle loads through the site. The arrangement is shaped around water depth, channel width, access, loading reach and the available transfer point.
Material testing, permissions and the final disposal route remain project-specific; our role is to make the marine excavation and waterborne handling system practical.
Channel maintenance
Keep the dredge face
and material route moving.
A constrained canal may leave little room for the excavator, loaded hopper and passing navigation. The marine setup therefore has to balance working reach, hopper capacity, manoeuvring space and the route to the transfer point.
Because WHH operates tugs, hoppers, crane and HIAB barges and modular platforms, the dredging setup can be assembled around the waterway rather than forcing a standard plant arrangement into it.

How we build the method
From channel constraint
to a repeatable cycle.
The aim is a dredging operation in which the work platform and material movements support each other.
Create the work platform
Configure an excavator, crane or specialist working platform around the dredge face, available water space and required stability.
Build the hopper cycle
Match hopper capacity, tug movements and loading sequence so excavated material can leave the workface without stopping the operation.
Plan the transfer route
Coordinate the waterborne movement and transfer point with the wider project arrangements for material handling, testing and disposal.
Restricted sites
Scale the platform
to the waterway.
Smaller road-mobilised HIAB barges and modular platforms create options where beam, headroom or launch arrangements rule out a conventional large dredging spread. Larger hoppers can then be introduced where the route and lock dimensions allow.
