Weed Cutting and Marina, Canal, River and Harbour Maintenance |
Using the innovative "Njord" class of amphibious boats Harbour Clean is able to offer a wide range of weed and reed cutting services, waterway maintenance and marina clearance operations, anywhere in the UK.
Operating in any depth of water, uniquely from zero to unlimited depth, the Njord class boats facilitate:
- weed cutting (to a depth of approx 2.2m (7)
- reed cutting on banks and at water depths of up to 2m
- bank cutting and reforming
- excavation and minor dredging works, and
- floating weed harvesting.
The Njord is an amphibious machine based on the innovative range of Truxor tool carriers (4600, 5000 and TR Classic), ideally suited to the maintenance and restoration of harbours, marinas, canals, waterways, marshes, ponds, embankments, flooded land, etc.
Easy-to-connect equipment facilitates a rapid installation of the appropriate tool kit, turning the machine into a dredger, mower, harvester or excavator in minutes.
The Njord is fully multi-functional allowing Harbour Clean to exploit the machine’s potential to the full.
This amphibious machine can be used for various operations:
• Mowing & Harvesting
• Dredging
• Excavating
• Oil-spill clean up
• Marine site maintenance
The Njord can be operated both on land as in water. The machine is very manoeuvrable and is capable of rotating on its axis in the water. It is therefore ideal for use in inaccessible marsh areas and shallow water.
Due to its light weight (1.2 tonnes) distributed over two broad tracks, it is suitable for sensitive areas such as parks, cultivated gardens and golf courses. The minimal ground pressure of the amphibious machine directs virtually no damage to the substrate during operation.
Accessories
Depending on the type of work, the relevant tools are attached to the lift arm or, if appropriate, directly coupled to the vessel’s hydraulics.
This machine is equipped with:
Different cutters for mowing
Rakes for cleaning / collecting the cut material
Skimmer for oil spill or blue algae
Dredging Pump for dredging
Excavation unit with different buckets for dredging, bank restoration, material handling, etc

Waterway Maintenance |
Floating debris and weed is an increasing problem in all marine environments.
Harbour Clean are able to offer three solutions:
- Cutting: in which specially adapted underwater shears cut plants near or on the seabed;
- Raking: in which innovative spiked rollers are trailed across the weed, pulling roots and plants from the seabed or harvesting the floating weed into dedicated storage bins; or
- Dyeing: in which special light inhibiting dyes are sprayed on the water that inhibit growth of the weed and/or kill the weed in situ.
Harbour Clean can advise and recommend specific weed control techniques on request.

Slipway and Pontoon Maintenance & Cleaning |
Cleaning of pontoons and slipways can be very time-consuming for busy harbour and marina staff - yet allowing a build-up of weed and algae can be both a health and safety issue and a poor reflection on the level of upkeep of a marine facility.

Utilising a combination of mechanical scrubbers, pressure washers and rotary cleaners, combined as appropriate with environmentally-sensitive (chlorite-free) solutions, Harbour Clean are able to provide the ideal solution to pontoon and slipway cleaning problems.
Designed to be unobtrusive to day-to-day operations, the Harbour Clean service may be tailored to budget and operational criteria to suit the customers specific requirements.

Tier1 / Tier 2 Oil Spill Support |

Marine Civil Engineering Support |
Utilising their fleet of highly manoeuvrable and multi-purpose workboats, Harbour Clean are able to offer stable, adaptable and spacious work platforms for a multitude of support functions to the marine civil engineering sector.
Shallow draft (<6”; <150mm) operation ensures that close inshore and inter-tidal areas may be worked for extended periods of the tidal window. Due to their strengthened flat-bottom design, the vessels are also able to dry out over low water, even when loaded.
Low air-draft (approx 750mm) means that inshore spans of bridges and the undersides of low structures (such as linkspans) may be accessed afloat for extended periods.
The ‘Nirvana’ class is able to load contractor’s plant (compressors, generators, power tools, etc) up to a maximum of 1000kg on a clear deck, accessible direct from the shore via a strengthened bow ramp (capable of lowering to -20° below horizontal).
Waste material may be easily removed from site via wheelbarrow loads over the bow door or via specially adapted heavy-duty collapsible bins that are suitable for pallet-truck or forklift transport.
SITE CLEARANCE AND RE-ESTABLISHMENT AT THE END OF PROJECTS AT EXTREMELY COMPETITIVE RATES.

Personnel/Equipment Transport |
The Nirvana class workboat is capable of loading and unloading a range of wheeled plant and equipment via a strengthened bow door.
Equipment, personnel, tools or cargo up to 1000kg (gross) may be carried (subject to weight/height distribution restrictions). Specially adapted heavy-duty collapsible bins may carry loose cargo and be loaded by pallet truck or light forklift.
Personnel (up to 5 persons in total) may also board dry via the bow door direct from the shore (bow door lowers to -20° below horizontal and is ribbed for non-slip access).
Persons in the water, or on other boats, may board conveniently with the bow door lowered to water level.
The main deck is self-draining and the double-bottom tanks ensure excellent stability even with the main deck flooded.
Vessel is certificated as a Passenger Vessel by Portsmouth City Council. Additionaaly, the vessel is manned and equipped in accordance with the requirements of the Small Commercial Vessel Code and as set down by the Solent and Southern Harbour Masters Association (SASHMA) and the Maritime & Coastguard Agency.
