Hammelmann Ship cleaning systems
Efficient corrosion protection thanks to innovative high-pressure water jet technology
Economic ship cleaning
- Reduced docking time.
- Saving of costs and effort: The priming can be carried out after the approval of the inspector. No additional cleaning is required after surface treatment.
- Ensuring even energy distribution across the entire working width.
- Enormously increased area performance with the same pump output.
- No costs for intensive shielding of sensitive devices, reduced time for cleaning the dock. The seaworthy equipment and machinery located nearby are not damaged by water, unlike by flying sand particles.
- More efficient workflows: other trades can work close to the water jet area.
- Significantly lower disposal costs than with dry blasting. The water can be treated and reused. Only wastewater, old paint, marine growth and rust need to be collected for separation and disposal.
- Work in all weather conditions.
- Longer working times: the vacuum tank only needs to be replaced when it is filled with sludge or silt. The filtered (but untreated) water is pumped out of the vacuum system.
- Reduction in personnel costs: The amount of operating personnel required is reduced.
Environmentally friendly components and systems
- No dust development as dust particles are bound in the water.
- The amount of material to be disposed of is 1/100 compared to dry blasting.
- Systems with suction devices allow the waste water and the removed paint particles to be fed directly into a post-treatment system.
- Simple waste separation for controlled disposal. Wastewater can be collected if the dock does not have central water collection and treatment facilities.
- The sludge is collected in the settling tank and can be tipped into a container. Optionally, a replacement tank for quick replacement or an XXL filter bag that can be lifted out of the settling tank can be used.
Surface treatment of the highest quality
- Exposing the surface profile beneath the original coating.
- Optimum adhesion to fresh coatings, especially surface-tolerant paints.
- Consistent removal quality due to constant feed and distance between the nozzles.
- Significantly better surface quality when using UHP water jetting compared to conventional methods.
- The ship’s hull remains free of foreign bodies, corrosive materials or poorly adhering coatings.
- No subsequent cleaning of the surfaces is necessary, as with other methods.
- The substrates prepared with Hammelmann systems meet the quality requirements of international paint manufacturers and standardization authorities (NACE/SSPC) for the application of new coatings.
Partially and fully automated processes for high security standards
- No risk of silicosis and other respiratory diseases.
- Less physical strain on the operating personnel compared to lifting by hand.
- No clouds of dust and dirt that endanger the health of operating personnel.
- Vacuum eliminates radiation noise.
Waterjet standards according to ISO 8501-4 - SSPC / NACE
Wa 2½: Very thorough high-pressure water blasting > Wa 2: Thorough high-pressure water blasting > Wa 1: Light high-pressure water jet
or
WJ 2: Very thorough or extensive cleaning > WJ 3: Thorough cleaning > WJ 4: Easy cleaning
The perfect couple
The DOCKBOY and the DOCKMATE are the perfect combination when it comes to the efficient processing of ship surfaces. Both cleaning systems are automated and safe and are operated by just one operator. Working with several devices at the same time is possible and opens up completely new dimensions of area performance!
DOCKBOY
Flexibility and performance for reliable results: the DOCKBOY is a modern and compact carrier vehicle for processing the sides and bottom of ships. The DOCKBOY is an irreplaceable performer, especially for work on the undersides. The vehicle height is only approx. 1.40 m with the extension arm set to the minimum and is therefore lower than most standard keel pallets!
DOCKMATE
Developed for large tasks: the DOCKMATE is a modern carrier vehicle for working on the sides of ships. With working heights of almost 33 m and a large working width of 1000 mm, the DOCKMATE impresses with its unrivalled removal performance. Ship walls and all types of curves can be easily processed with the DOCKMATE.
Practical application examples
- Removal of old paint layers from ship walls
- Remove paint from intermediate surfaces and work around tight contours
- Thoroughly clean and remove paint from ship's roundings
- (Semi-) automatic operation, without fixed yard installations
- Clean and remove paint from ship bottoms quickly and easily
- Prepare ship surfaces NACE/SSPC compliant
- Prepare ships ideally for corrosion protection
- Derusting of metal surfaces
All product solutions for the marine industry
DOCKBOY
The DOCKBOY is a remote controlled cleaning vehicle for the ship industry. With working heights from 0 - 13 m, it is ideal for working on the hull bottom.
AQUABLAST® Line
The AQUABLAST® Line is a device for carrier systems and is suitable for cleaning and decoating vertical or vertically inclined surfaces.
DOCKMATE
The DOCKMATE is a remote controlled cleaning vehicle with a separate high-pressure unit. With a working height of 32 m, it is designed for work on the hull.
JETBOY working tools
JETBOYS are ergonomic working tools in various configurations for fatigue-free water jetting - adjustable for a wide range of working positions.
SPIDERJET®
SPIDERJETS® are highly mobile, self-adhesive cleaning vehicles with maximum maneuverability and high area performance. Suitable for every challenge.
Mobile wastewater treatment
The possible applications of mobile wastewater treatment are very extensive. In many industries where water is used as a working medium, it can no longer be reused after just one cycle as it becomes too contaminated during the work process.
JETMATE working tools
JETMATES are ergonomic, free-hanging working tools that can clean in all directions. Safe and less physical stress on the body thanks to recoil-free operation.
Injection pumps for green fuels
Prepare for the future today with our injection pumps for alternative fuels (green fuels). We are accompanying the international maritime industry on its course towards climate neutrality.
