Wärtsilä Water & Waste Continues Its Operations Under the Hamworthy Name

Marin İstanbul is pleased to announce that the Wärtsilä Water & Waste business unit, with which we have maintained a long-standing relationship, continues its operations under the Hamworthy name following its new organisational structure.

Wärtsilä Water & Waste has been providing marine environmental solutions based on many years of expertise and engineering experience in water and waste management. Following the organisational transition effective 1 June 2026, these activities are continuing under the Hamworthy name as an independent marine water and waste specialist.

With this transition, the brand and organisational structure have changed, while the products, solutions, technical expertise and services provided to customers remain in place. Hamworthy continues to provide comprehensive systems and solutions addressing key needs within the maritime sector, from ballast water and wastewater treatment to freshwater generation and onboard waste management.
