Wärtsilä Aquarius BWMS uses a two-stage process involving both filtration and electro-chlorination (EC), and is compliant with EX / ATEX requirements.

Wärtsilä Services sales support, development and projects general manager Giampiero Cubellis said: “We work in close cooperation with our customers, and our BWMS partnership programme covers all stages from fleet evaluation to lifecycle support, making sure our customers can choose a service that is best suited to their specific needs.”

The international convention for the control and management of ships’ ballast water and sediments (BWM Convention) was adopted in 2004, in order to introduce global regulations that control the transfer of potentially invasive marine species between waterways around the world.

"Wärtsilä was able to offer a strong safety-led and reliable design approach that is expected to meet the requirements of the complex market we operate in."

The BWM Convention is set to enter force on 8 September, and will require ships to release treated ballast water into the sea in order to protect the aquatic or marine microbes, plants and animals.
