Sonihull

What Sonihull does

Sonihull develops and markets ultrasonic anti-fouling systems for marine vessels, using proprietary non-inertial cavitation technology to prevent biofouling on hulls, propellers, sea chests, coolers, strainers, and pipework without chemicals, biocides, or through-hull penetrations. The product line comprises two variants: the standard Sonihull system and Sonihull Xtreme, an advanced platform with proprietary algorithms and intelligent thermal management targeted at large commercial and naval vessels. Each system is built around an electronic control unit driving up to 16 independent transducers that can be mounted up to 100 metres from the controller without performance loss, enabling flexible protection across multiple surfaces from a single system.

Founded in 2008 and headquartered in Coventry, United Kingdom, Sonihull operates as a wholly-owned product brand within Alfa Laval, a Swedish multinational engineering company listed on Nasdaq Stockholm. The business generates revenue through capital-equipment sales of Sonihull systems with associated installation and service, executed through an enterprise, consultative sales motion. All sales, specification, installation, and after-sales support are channelled exclusively through Alfa Laval Marine Service's global 24/7 network, with pricing provided on a quotation basis rather than publicly listed. Customers span two broad segments: commercial shipping (tankers, cargo vessels, cruise ships, naval vessels) where even marginal gains in propulsion or cooling efficiency translate to material fuel savings, and small/mid-sized vessels (support vessels, fishing boats, ferries, tugs, pilot boats, superyachts) where higher biofouling exposure creates operational risk. Documented customer outcomes include up to 3% propeller fuel savings over a five-year horizon, a four-month payback for a Greek VLCC operator, and 18+ months of maintenance-free operation on a Turkish passenger ferry.

Core offering

Sonihull designs, manufactures, and sells ultrasonic anti-fouling systems that prevent biofouling on vessel hulls and submerged surfaces without biocides or cleaning chemicals. Each system comprises an electronic control unit and up to 16 independent transducers that use non-inertial cavitation to generate acoustic pulses in targeted ultrasonic frequencies, keeping hulls, propellers, sea chests, coolers, strainers, and pipework free of algae, barnacles and other organisms. The product family includes the standard Sonihull system and the advanced Sonihull Xtreme variant built for the largest commercial vessels.

Product overview

Sonihull is a unified ultrasonic anti-fouling product line offered by Alfa Laval, consisting of Sonihull (standard version) and Sonihull Xtreme (advanced version). The core Sonihull system comprises electronic control units with up to 16 independent transducers that generate targeted ultrasonic frequencies, creating microscopic agitation through non-inertial cavitation to keep hulls, propellers, sea chests, coolers, and pipework free from biofouling. Sonihull Xtreme extends the platform with advanced algorithms and intelligent thermal management specifically optimized for large vessels like tankers, cargo vessels, cruise ships, and naval vessels.
