Hamworthy

About Hamworthy

Hamworthy designs, engineers and supports integrated marine water and waste systems for shipowners, operators, shipyards and technical specifiers working under constant regulatory and operational pressure. We are the independent continuation and evolution of Wärtsilä Water & Waste. The expertise, installed base, engineering capability and long-term customer relationships continue under the Hamworthy name. Together with our endorsed brand Serck Como, we bring more than 180 years of combined marine engineering heritage to a single specialist business. Marine water and waste is all we do. Our portfolio covers ballast water management, sewage treatment plants, membrane bioreactors, oily water separators, dry waste systems, freshwater generation and compressors. We design these as integrated systems rather than standalone equipment, and support them from specification through commissioning, service, retrofit and end of life. We work across cruise, merchant shipping, offshore, naval and specialist vessels, and partner with shipyards on both newbuild and retrofit programmes. Compliance is the baseline. What customers actually need is the confidence that the system holds when it is inspected, that someone picks up the phone in a port they did not plan for, and that five years from now their systems will still be supported. Every vessel takes in water and produces waste. All of it has to be treated, managed and discharged to standard. We design the systems that make sure that happens, and we stay with them for the full life of the asset. Protect tomorrow by treating today. Our commitment extends beyond product delivery; we offer unparalleled lifecycle support, including OEM spare parts, technical assistance, and system upgrades, ensuring optimal performance and peace of mind for our clients worldwide.​
