NRG Marine (NRG) manufactures ultrasonic anti-fouling systems that destroy algae to remove fouling of the hull of ships, tugboats and commercial vessels through ultrasonic vibration technology.

As a subsidiary of NRG Solutions, the company also develops and produces ultrasonic generators to protect filters, inlets, valve seats and associated pipe-work.

Solutions to improve speed and propeller cavitation of ships and tugboats

NRG develops and manufactures solutions to marine growth on vessel hulls.

For hundreds of years mariners have been plagued with the problem of marine growth on ship hulls, power train and steerage gears. This causes problems such as:

The Sonihull system is an environmentally friendly solution that protects ship hulls against algae, fungi and barnacle build-up.
NRG’s anti-fouling solutions ensure that ship hulls are free from organic growths that may reduce efficiency.
The electronic anti-foul system releases patterns of alternating positive and negative ultrasonic pressures, which do not harm marine life.
The Oceonic Sea Chest Protection System ultrasonic generator protects valve seats, filters, inlets and pipe-work.
  • Reduced speed, due to extra drag
  • Increased fuel consumption, estimated at as much as 20%
  • Propeller cavitation, which in turn causes extensive damage to propellers
  • Expensive annual haul-out and repainting

Eco-friendly electronic anti-foul solutions for tugboats and commercial vessels

The NRG Marine Hull protection system for ships uses the latest digital electronics and ultrasonics transducer technology to produce multiple bursts of ultrasonic energy simultaneously in a range of frequencies. This energy produces a pattern of alternating positive and negative pressures.

The alternating pattern creates microscopic bubbles during periods of pressure and implodes them during periods of positive pressure in a phenomenon known as ‘cavitation’. The implosion creates a micro-jet action that not only provides the cleaning effect on the hull’s surface below the water line, but also resonates and destroys single cell organisms such as algae. Removal of the initial link in the food chain inhibits the growth of barnacles and other marine life that feed on the algae.

The Sonihull System is an environmentally friendly solution for marine anti-fouling in general that is suitable for all types of hull materials, excluding wood.

Ship anti-fouling system that are safe for marine life

A clean hull can save you about 20% on your fuel bills. It is common knowledge that fouling on a ship’s hull will lead to increased resistance, which requires more fuel for every knot. The outcome is compromised efficiency and a poor miles per gallon ratio. This can be combated with a clean hull coated in anti-fouling paint.

Although fouling is usually suppressed through the use of anti-fouling paint, it is known to be damaging to the environment; however, tests show that NRG Ultrasonic Anti-fouling Systems pose no danger to marine life.

NRG Ultrasonic Anti-fouling Systems are environmentally friendly, cost-effective and chemical-free. Using ultrasound to destroy algae cells was discovered decades ago, but considered too costly to make it a marketable product.

Today, the NRG Sonihull ultrasonic sound wave generation is now available and affordable for those who want to get rid of algae and other harmful micro-organisms, such as destructive root parasitic fungi, Fusarium and Pythium. It is inaudible and poses no threat to people, animals, fish or plants.

Ultrasonic system to protect filters, inlets and pipework

The Oceonic Sea Chest Protection System is an ultrasonic generator single transducer system suitable for both sailing and motor. The system protects inlets, filters, valve seats and associate pipe-work.
