THE FUTURE OF
ANTI-FOULING, NOW

FIT & FORGET BIO-FOULING PROTECTION

Wherever your vessel is exposed to raw seawater you need to protect against biofouling. On the outside, the build-up of algae, weeds, barnacles and other unwanted marine life will slow you down and increase your fuel bill. On the inside, marine organisms can restrict cooling water and even damage your engine. That is where our ultrsonic antifouloing system comes in to action. 

Sonihull Ultrasonic
Anti-fouling System

NRG Marine uses the latest digital electronics and ultrasonic transducer technology. This system works by producing bursts of ultrasonic energy in multiple frequencies, the energy creates a pattern of alternating positive and negative pressure. Microscopic bubbles are created from the negative pressure, while the positive pressure implodes them forming vapor cavities known as cavitation. The result of the implosion is a micro jet action that creates a cleaning effect on the hulls surface below the waterline. It also resonates and destroys single cell organisms such as algae. Disrupting this first link in the food chain keeps the surface clean and makes it a much less inviting habitat for larger organisms that feed on the algae. The microscopic movement of water also prevents barnacle and mussel larvae from embedding on the surface.

Used by the marine industry

Traditional self-polishing antifouling coatings struggle to perform in water-jet applications. When stationary, the coatings don’t work and during operation, the biocides in the paint don’t last long because they are leached much more quickly than usual, due to the increased pressure and water flow. Instead of using poisons,Sonihull uses ultrasonic antifouling technology to disrupt marine organisms on the water-jet surfaces.

This maintains as-new vessel performance, and readiness without disruptive maintenance, even during long periods of inactivity

Trusted by Coastguards, Navy, & SAR Services

This maintains as-new vessel performance, and readiness without disruptive maintenance, even during long periods of inactivity. Following exhaustive evaluations on Naval and Coastguard craft around the world, Sonihull is now fitted by leading waterjet manufacturers to provide long-term protection against marine fouling.

Sonihull understands that in the high-performance defence and patrol sectors, reducing downtime and increasing MTBO (mean time between overhauls) is crucial. Even relatively light fouling can drop top speed by 20%, creating a corresponding spike in fuel consumption and mechanical wear. Antifouling, therefore, becomes a key operational cost, something that Sonihull helps coastguards and navies minimise.

Loved by Most Discerning Customer on Earth

With easy installation, PLC integration and quiet operation, Sonihull has become a firm favourite in superyacht machinery spaces. As well as preventing the build-up of marine organisms on raw water surfaces like sea-chests and pipework, Sonihull will also suppress Diesel bug in fuel tanks and will keep potable water fresher for longer in water storage tanks.
 
The superyacht sector may appear to be all about the finished product and superior levels of service, but all that sparkle wouldn’t exist without myriad onboard systems and equipment working flawlessly behind the scenes. Most superyachts are operated as commercial entities and are under similar time and performance pressures as other floating assets. In order to reduce downtime and maximize charter income, superyacht owners and operators have always been keen to introduce new technologies like Sonihull to keep their vessels out of drydock for as long as possible..

Sonihull8

Sonihull8 is the latest addition to NRG Marine’s Sonihull range of ultrasonic antifouling systems. Sonihull’s fit-and-forget systems prevent marine organisms colonising solid surfaces that are exposed to raw seawater. With eight independent and programmable outputs, Sonihull8 ultrasonic antifouling systems can protect every part of your vessel or structure from marine fouling. Unlike biocidal coatings and impressed-current systems, Sonihull8 is low cost and low maintenance, with zero poisonous environmental legacy. With one panel and eight transducers, Sonihull8 has all of your equipment covered.
