Effective removal of Algae and Shells with High-Pressure Water
Algae, mussels, barnacles and other organic organisms settle on a ship’s hull over time. This so-called biofouling has two main effects. As a result of the adherence of fresh water and saltwater organisms, the ship’s hull becomes rough, which increases the hull’s resistance and hence increases the energy required for a given speed. Furthermore, the danger of corrosion on the hull increases due to the environment generated by the biofilm on the ship’s hull.
The removal of the organisms with nozzle technology, driven with high-pressure pumps, is an efficient method of cleaning a ship’s hull. WOMA high-pressure systems have been established for this area of application over many years: With manual gun systems, and up to 43,500 PSI pressure, the hull’s fouling can be removed completely by high-pressure water jets. High-pressure guns and rotating nozzles as accessories to WOMA high-pressure plunger pumps, offer both a high level of controllability of the gun and the ability to efficiently clean large areas.
What high-pressure jetting can do for ships applies also to buoys, cans and beacons, docks, barrages and ship lifts.
WOMA water tools for water blasting applications are the optimum solution in the ship and shipyard industry:
- Cleaning of ship hulls
- Cleaning of superstructures and on-board equipment
- Cleaning of ballast tanks
- Cleaning of tanks, vessels and internal pipe systems
Features/Advantages
- Does not require wrapping or unwrapping of vessels. Customers save large amounts of time, labor and material costs related to wrapping and unwrapping a vessel.
- Generates very low impact forces on surfaces; working almost vibration-free. No substrate material will be removed. Hence a customer avoids damage on their structures.
- Can be used in rainy or windy environment. Hence the customers are not dependent on weather conditions and can readily schedule work with a high reliability.
- Guarantees the highest possible cleanliness level among all surface preparation methods. The remaining level of salt, chloride and other elements is minimized. There is no embedded grit as found after grit blasting being a source for new corrosion. The customers therefore can offer an excellent surface to the painter with minimal risk of osmotic blistering.
