How It Works

Yacht Shield effectively shield vessels from the damaging effects of marine biofouling. Our ultrasonic systems harness advanced ultrasound technology to deter microorganisms from adhering to surfaces exposed to raw seawater. By transmitting ultrasound wave energy through these surfaces, a thin layer of high pressure is generated, forming a protective barrier that obstructs the passage of fouling organisms.

In simpler terms, each ultrasound pulse induces subtle vibrations in the surface material, repelling fouling organisms and ensuring surfaces remain cleaner for longer periods. Trust Yacht Shield, delivered by Australian Marine Sales, to uphold the pristine condition of your vessel.

Benefits of Ultrasonic Antifouling

Maintaining a clean hull dramatically increases performance, speed, and overall fuel efficiency. Yacht Shield ultrasonic antifouling ensures you’re vessel is running at peak performance.

Ultrasonic Antifouling

Revolutionising Marine Maintenance

Ultrasonic antifouling technology offers a modern solution to an age-old problem faced by boat owners and the marine industry—biofouling. Biofouling, the accumulation of microorganisms, plants, algae, or animals on wetted surfaces, presents a significant challenge as it can decrease a vessel’s performance and increase fuel consumption. By employing high-frequency sound waves, ultrasonic antifouling systems prevent the growth of unwanted organisms on a boat’s hull, thereby maintaining its efficiency and reducing the need for harsh chemical antifouling paints.

Installing an ultrasonic antifouling system involves fitting transducers inside the hull, emitting sound waves that create an environment inhospitable to potential

foulers. This non-toxic approach is gaining traction as an eco-friendly alternative to conventional methods, resonating with the growing awareness and regulation around marine preservation. It operates silently and can be used on various types of vessels, making it an adaptable solution for the industry.

The technology, while advanced, is designed for straightforward operation and is accessible for boat owners looking to protect their investment and contribute to environmental conservation. As research and development continue, advancements in ultrasonic antifouling systems are expected to enhance their effectiveness and efficiency, positioning them as a competitive option in the market.

Fundamentals of Ultrasonic Antifouling

Ultrasonic antifouling is a technology that uses sound waves to prevent the accumulation of organisms on submerged surfaces. It’s important to understand its effectiveness and the mechanism behind how it deters biofouling.

Does Ultrasonic Antifouling Really Work?

Reports and studies suggest that ultrasonic antifouling systems can be effective in preventing biofouling. These systems generate sound waves that create an environment that is not conducive to the growth of marine organisms. Frequency and power output are critical factors in the efficacy of these systems.

Users, you should evaluate the quality of the system and the conditions in which your vessel operates, as these influence the performance of ultrasonic antifouling. Performance can vary, but many users experience reduced growth compared to untreated surfaces.

How Ultrasonic Waves Prevent Fouling

Ultrasonic waves work on the principle that sound waves at specific frequencies create vibrations in the material they pass through. These vibrations discourage marine organisms from settling and growing on hulls, props, and other underwater metal structures.

Mechanism: When ultrasonic waves hit the surface, they create an unfavourable environment for biofouling organisms.
Frequency Range: Typically, frequencies between 20 and 40 kHz are utilised, tailored to disrupt the life cycle of common fouling organisms.

Ultrasonics don’t eliminate the need for regular maintenance, but they can significantly reduce the rate of biofouling. They effectively prolong periods between cleaning and reduce the reliance on chemical antifouling treatments. Remember, they’re a preventive measure, not a cure.

Components of Ultrasonic Antifouling Systems

Proper maintenance of your watermaker can significantly enhance its durability and reliability. It’s important to follow a regular service routine to ensure optimal performance. Here’s a straightforward guide to help you keep your system running efficiently:

Antifouling Paints

Antifouling paints are traditional coatings applied to the hull of a boat to prevent organisms such as barnacles and algae from attaching. Historically, these paints contain biocides, typically copper or tin compounds, which deter marine growth. Unlike ultrasonic antifouling, which uses sound waves to prevent fouling, antifouling paints create a toxic barrier.

Efficacy: Antifouling paints generally work well initially but can decrease effectiveness as the paint releases its biocide over time.
Maintenance: You must reapply antifouling paint periodically, typically every one to three years, depending on the paint type and your boat’s usage.
Environment: These paints can be detrimental to marine life due to the leaching of chemicals, an issue not present with ultrasonic systems.

Mechanical Cleaning Methods

Mechanical cleaning includes methods like scraping, water jetting, and hull brushing to physically remove fouling from your vessel’s hull. These methods can be labour-intensive and may require dry docking of the boat.

Efficacy: Mechanical methods effectively remove developed fouling but do not prevent new growth, unlike ultrasonic antifouling, which continually deters organisms.
Maintenance: More frequent attention is often required, with some boat owners performing mechanical cleaning several times per year.
Environment: Mechanical cleaning can have minimal ecological impact, but it often results in the immediate release of fouling organisms and biocides from old paint into the water.

Market and Industry Applications

In the marine sector, ultrasonic antifouling technology is pivotal for maintaining vessel performance and reducing maintenance costs. Adopted across various industry segments, it offers a clean and efficient solution to biofouling.

Commercial Shipping

Commercial shipping is a significant segment incorporating ultrasonic antifouling systems to protect submerged hulls and surfaces. Your fleet efficiency relies on these systems to reduce drag and fuel consumption spurred by biofouling. Market trends suggest a growing demand for these systems as regulations tighten on environmental impacts and biosecurity risks associated with vessel-borne invasive species.

Applications: hulls, tanks, seachests
Benefits:

• Fuel Efficiency: sizable reductions in fuel consumption

• Maintenance: decreased dry-docking frequency

Recreational Vessels

Recreational vessels, from yachts to motorboats, greatly benefit from ultrasonic antifouling applications. Your vessel must maintain speed and aesthetic appeal, which these systems ensure without the frequent need for hull scrubs and paint jobs.

Systems: transducers strategically placed along the hull
Market Adoption:

• High: particularly in regions with warmer waters conducive to rapid marine growth

Using strategic placement of ultrasonic devices within your vessel’s structure can extend the lifetime of coatings and components, ultimately protecting your investment.

Advancements and Innovations

In the field of ultrasonic antifouling, transducer technology has significantly improved. Modern transducers are compact and energy-efficient, producing high-frequency ultrasound waves with greater precision. The innovative application of these waves has broadened the scope of antifouling systems and enhanced their performance.

Advancements in innovation and development include:

Smart Control Systems: integration of microcontrollers that automate the ultrasonic output based on fouling levels
