What Hamworthy does
Hamworthy is a marine engineering company headquartered in Poole, United Kingdom, that designs and manufactures water and waste handling systems for commercial, naval, cruise, offshore, and specialist vessels. Its product portfolio spans ballast water management systems (including UV-based treatment under the Aquarius UV and Aquarius UVX lines), wastewater treatment plants, freshwater generators using reverse osmosis desalination, and onboard solid waste handling equipment, alongside the Serck Como heat exchanger business acquired in 2006. The company operates a global sales and service network spanning more than 30 countries and holds approximately 4% of the global ship desalination market.
The company generates revenue through three primary channels: equipment sales to shipyards and vessel operators via OEM partnerships, aftermarket spare parts, and lifecycle service contracts tied to its installed base. Its products are certified to international regulatory standards including IMO, USCG, and major classification societies, which is a prerequisite for market access. Named customers include the Royal Navy, Cunard, Chemgas, Hallin Marine, and Leonidas, spanning naval, cruise, and commercial segments. Hamworthy was founded in 1914 and historically operated as part of Wärtsilä Water & Waste before being divested to Solix Group AB in June 2026, with Fraser Scott serving as CEO.
