Alfa Laval acquires NRG Marine to tap potential of ultrasonic anti-fouling tech

Swedish marine technology company Alfa Laval has signed an agreement to acquire NRG Marine, the UK-based provider of ultrasonic anti-fouling solutions for marine, oil and gas, and industrial applications.

The acquisition, expected to close in the second quarter of 2025, aims to leverage the increased use of ultrasonic anti-fouling technology, which is poised to grow in demand across significant industries.

As explained, the move enables Alfa Laval to extend its portfolio to innovative new technologies. Ultrasonic anti-fouling has many advantages compared to other technologies as it is considered more sustainable and in line with expected future legislation.

Specifically, NRG Marine’s technology uses ultrasonic microscopic bubbles to cause agitation to reduce fouling and hamper the rebuild of new deposits. This method reduces biofouling, scaling, sludge and deposits on critical components, with significant operational and environmental benefits for marine, oil and gas, and other industrial markets.

“In the race to net zero, solutions that enhance energy efficiency and operational performance are more essential than ever,” Sameer Kalra, President of the Marine Division at Alfa Laval, commented.

“The inclusion of ultrasonic anti-fouling technology into our portfolio is another addition to our decarbonization toolbox. By addressing the critical problem of biofouling with this advanced technique, we will enable our customers to meet both business and environmental objectives.”

“We are excited to join forces with Alfa Laval through this acquisition to extend ultrasound technology for anti-fouling treatment to marine, oil and gas, and other industrial sectors,” Darren Rowlands, Founder & CEO of NRG Marine, said.

“Alfa Laval’s commitment to sustainable solutions and extensive global network make them an ideal partner for us. This strategic move will increase our market reach and scalability, making our solution more accessible to customers.”

For marine vessels, fouling is not just important from a fuel savings and decarbonization perspective. Biofouling, the accumulation of organisms on ship parts, increases the risk of spreading invasive species, leading to ecological and economic harm. Anti-fouling systems are crucial for mitigating this issue, reducing the spread of invasive species, and protecting marine ecosystems.

For the oil and gas sector, this technology helps prevent and clean the stationary surfaces to avoid biofouling. Being ATEX-approved, it complies with required safety standards that make it reliable and safe.

Ultrasonic anti-fouling technology emerges as a promising alternative to other methods, offering significant advantages across industries. Fitting the system improves the operational efficiency of the asset, reduces maintenance while lowering cleaning costs and extends the asset’s lifecycle, according to Alfa Laval.
