Waterway & waterspace management

Keep the asset
working.

WHH combines specialist vessels, plant and experienced crews to maintain waterway assets and manage estate waterspaces, lakes and other water bodies.

Management built around the waterspace

Keep the water
working well.

Waterway assets are often easiest to reach from the water—and hardest to maintain with standard plant. Managed waterspaces also need practical, regular attention to remain safe, attractive and operational.

WHH provides vessels, equipment, storage and experienced crews for estates, landowners, marinas and waterway authorities. We can manage aquatic weed and floating litter, support dredging and vegetation work, or inspect, repair and maintain locks, weirs, channels and waterside structures.

One move.
Both ends of the lock.

Jumbo is WHH's specialist lock-gate replacement barge. Its two cranes allow work at both ends of the lock without reconfiguring the site between operations.

The large hold can carry the plant, temporary works and materials for a complete stoppage in one movement, cutting mobilisation time and keeping the lock chamber organised throughout the programme.

From inspection to intervention

A practical route
to maintained assets.

The vessel configuration should support the whole operation: access, lifting, storage, navigation and the sequence of work.

01

Inspect & understand

Provide waterborne access for inspections, surveys and condition assessment where the asset cannot be reached safely or practically from land.

02

Configure the vessels

Match working space, lifting capacity, hold volume and manoeuvrability to the asset, waterway dimensions and closure arrangements.

03

Mobilise efficiently

Carry plant, materials and temporary works to site by water, reducing land access requirements and repeated mobilisation movements.

04

Deliver the works

Provide experienced crews and practical marine coordination alongside the client, principal contractor and waterway authority.

Across the network

Different waterspaces.
Adaptable methods.

From estate waterspaces and lakes to urban weed cutting and rural lock stoppages, the common requirement is practical equipment in the right place.

Waterborne access supports close inspection and maintenance planning for structures that are difficult to assess safely from the bank.

Dredging and silt handling

Tugs, hoppers and excavator platforms configured to excavate, contain and move dredged material along the waterway.

Aquatic weed management

Targeted cutting and collection restores navigable water and removes the arisings as part of one coordinated operation.

Stop-plank handling

Dudley provides crane capacity and a stable working platform for lifting heavy stop planks in a constrained lock environment.

Unusually small lock

Reconfigure the platform,
not the project.

An adaptable split pontoon was fitted with stabilising beams, a crane chassis and HIAB crane to create a capable lifting platform within a lock too small for a conventional crane barge.

The arrangement illustrates the wider WHH approach: start with the physical and operational constraint, then assemble the required vessels and equipment around it.

Typical applications

Practical management
from the water.

  • Lock gate replacement and repairs
  • Managed waterspaces for estates and landowners
  • Weir inspection and maintenance
  • Dredging and silt removal
  • Aquatic weed and floating litter management
  • Stop-plank and temporary dam handling
  • Vegetation and debris removal

Plan the marine method

Show us the asset, access and intended intervention.

We can help establish the vessels, equipment, working arrangements and programme needed to maintain an asset or manage a waterspace effectively.
