The Wärtsilä Hamworthy Aquarius UV BWMS

Wärtsilä Hamworthy has won a contract to supply ballast water management systems (BWMS) to four platform supply vessels (PSVs) being built in China for offshore service provider Tidewater Marine.

The scope of supply for the vessels, due for delivery from the COSCO (Guangdong) Shipyard in 2014, includes four 250m3/h capacity AquariusUV treatment systems, which will be assembled and shipped from Wärtsilä Hamworthy in the UK. The AquariusUV is a modular system using filtration and medium pressure UV disinfection technology. Recognising the associated operational profile, AquariusUV was favoured over the alternative AquariusEC system due to owner technology preferences and more favourable space, power and cost constraints on this ship application.

The first system is scheduled to be delivered to the shipyard in January 2013 and the rest will follow at two-month intervals.

“This contract is our first commercial order for PSVs and the selection of a Wärtsilä ballast water management system by Tidewater Marine underlines confidence in our ability to deliver in this emerging market” says Dr Joe Thomas, director, ballast water management systems, Wärtsilä environmental solutions.
