Alfa Laval to Acquire NRG Marine

Swedish manufacturing company Alfa Laval has announced that it is to acquire NRG Marine to advance innovative antifouling technology. 

Established in 2006, NRG Marine has developed a novel antifouling technology called Sonihull. As you may have guessed from its name, Sonihull uses ultrasonic waves to prevent biofouling from occurring on surfaces such as ships’ hulls. 

The acquisition is expected to result in the increased use of Sonihull technology across a broader range of industries. 

Ultrasonic antifouling has many advantages compared to other technologies as it is considered more sustainable and in-line with expected future legislation. 

Commenting on the acquisition, Sameer Kalra, president of the marine division at Alfa Laval, said: 

“In the race to net-zero, solutions that enhance energy efficiency and operational performance are more essential than ever.

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

NRG Marine’s Sonihull technology uses ultrasonic microscopic bubbles generated by ultrasonic waves to reduce fouling and hamper the rebuilding of new deposits. This effective and proven 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. 

Founded over 140 years ago, Alfa Laval has customers in 100 countries, employs more than 22,000 people and has annual sales in the region of €5.5 billion. 

The acquisition is expected to complete during Q2 2025.
