TRUSTED BY COASTGUARDS, NAVY & SAR SERVICES

Traditional self-polishing antifouling coatings struggle to perform in waterjet 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 waterflow.

Instead of using poisons, Sonihull uses ultrasonic antifouling technology to disrupt marine organisms on the waterjet surfaces.

Performance

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.

 

TRUSTED BY THE MOST DISCERNING CUSTOMERS 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.

Superyachts

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.

 

 

TRUSTED BY SAILORS & MOTORBOATERS

Arguably, the most diverse marine market for Sonihull is the leisure boating sector.

Sonihull is safe to use on steel, aluminium and resin-infused composites and is mostly used to protect the hull and underwater gear from marine fouling.

All Sonihull systems produce multiple bursts of ultrasonic energy in a range of targeted ultrasonic pulse frequencies. These pulses are transmitted through the material that the transducer is attached to, your hull, prop shaft, stern drive or IPS.

Ultrasonic energy

The pulses produce a pattern of alternating positive and negative pressure on the surface of the material that is in contact with the water. Microscopic bubbles are created during the negative pressure cycle and are imploded during the positive pressure cycle.

This microscopic agitation has a cleansing effect that destroys surface algae, the first link in the marine food chain. Disrupting the food chain keeps the surface clean, making it a much less inviting habitat for larger organisms that feed on the algae. As well as preventing the creation of a biofilm, the microscopic movement of water also prevents barnacle and mussel larvae from embedding on the surface.
