Two product lines

Wärtsilä Water & Waste is a collaboration between two of Wärtsilä's product lines: Wärtsilä Water Systems Ltd in Poole, UK, and Wärtsilä Serck Como GmbH in Geesthacht, Germany.

The design, engineering, production coordination, spare part management & service delivery for our freshwater generators takes place at Wärtsilä Serck Como. The same activities for our ballast water management equipment and our waste and wastewater treatment units are coordinated by our colleagues in Poole. 

    WARTSILA WATER SYSTEMS LTD

    Until 2012, Wartsila Water Systems Ltd was known as 'Hamworthy plc'. As of January 2012 Hamworthy became part of the Wärtsilä organisation.  

     History of Hamworthy

    The Hamworthy business was founded in 1914 on Poole Quay in Dorset and quickly established a reputation in the marine engineering business.

    It was acquired by Powell Duffryn plc, a UK listed engineering and ports business in 1962. Subsequently, a series of acquisitions were completed, most notably Svanehøj International A/S in 1993 and the ships’ equipment division of the Norwegian Kværner Group in 1998.

    In 2000, Nikko Principal Investments Limited advised and financed the purchase of Powell Duffryn plc and during which time Hamworthy sold certain lower growth and margin activities and developed new products and technologies for the fluid handling systems for the marine and offshore sectors.

    In July 2004 Hamworthy announced the commencement of dealings of its Ordinary Shares on the Alternative Investment Market (AIM) of the London Stock Exchange. From July of 2004 Hamworthy continued to grow profitably by recognising a number of previous product development initiatives.

    In August 2006 Hamworthy acquired Serck Como GmbH, the market leader in desalination plants for cruise ships and condensors for industry.

    In order to increase the cost competitiveness of our gas systems business and augment the Group's wider design capabilities Hamworthy acquired Baltic Design Centre Ltd in November 2008.

    Greenship B.V. was acquired in March 2009 to enter the ships’ ballast water treatment market, an emerging market driven by international environmental regulations.

    In July 2009 Hamworthy acquired the business and assets of the Technology & Products division of Aibel AS, the Norwegian oil services company. The acquisition represents continued progress on implementing our strategy of expanding our presence in the offshore oil & gas market.

    In September 2009 Hamworthy acquired Krystallon Ltd, a leading player in marine exhaust sulphur emissions reduction technology. The emerging market for marine sulphur emissions reduction is an exciting global opportunity underpinned by international environmental regulations. The acquisition of Krystallon is consistent with our strategy of expanding the Group's technological base in long-term growth markets

    In October 2011 Hamworthy acquired AW Flow Holdings Ltd, and its subsidiary undertakings. AW Flow is a UK based specialist valve manufacturer for the oil and gas sector with oer 50 years' experience supplying global markets with specialist valve solutions. The acquired business has been merged with the Group's Pumps Systems business to form a new division, Hamworthy Flow Solutions.

    In January 2012 Hamworthy was acquired by Wärtsilä, a global leader in complete lifecycle power solutions for the marine and energy markets. Hamworthy’s portfolio of high technology products and systems represents a valuable complementary addition to Wärtsilä’s offering. The combining of the two companies’ strengths will speed up and ease the means for customers to reduce operating costs and achieve compliance with environmental legislation.

    WÄRTSILÄ SERCK COMO GMBH

    Wärtsilä Serck Como was founded in 1841 by the coppersmith C. August Schmidt in Hamburg. At that time the product offer included distillers and heat exchangers.

    Early on, Mr Schmidt started specialising in the development, design and production of seawater evaporation plants. The know-how acquired over decades has continuously been developed and fine-tuned, contributing greatly to the success of the company today. The continuous optimisation of existing products, as well as the development of new products, is part of Wärtsilä Serck Como's philosophy.

    Wärtsilä Serck Como GmbH develops, designs and manufactures single- and multi-stage evaporator systems for the production of fresh water from sea, well or industrial water. These systems are used on ships or on land. The fresh water that is produced serves as either industrial or drinking water. The evaporators can also be utilised to reduce the volume of  polluted industrial water.

    Wärtsilä Serck Como's scope of supply includes systems for post-treatment of produced distillate as well as tube heat exchangers and water- or air-cooled condensation systems. A globally present customer service team completed with a complete OEM spare parts supply service give our customers the necessary assurance when it comes to adequate after-sales support.

    Wärtsilä Serck Como today

    WSC has been located in Geesthacht since 1989. The company expanded in 2000 and in 2005. At that time more than 80 employees worked in product development, design, production, administration, service and sales. A modern and functional building located in a quiet industrial area surrounded by green, brings a pleasant working atmosphere. Competent and motivated employees produce high-quality products for our customers all over the world.

    In 2019 Reverse Osmosis has been added to WSC's technology scope, broadening its product portfolio with light weight and lower cost fresh water solutions.
