Wärtsilä Aquarius BWTS submitted for USCG type-approval
Wärtsilä expects its Aquarius electro-chlorination ballast water management system will receive USCG type-approval

With the Sulphur Cap 2020 Conference, Awards and Exhibition only a few weeks away, it is timely that Wärtsilä announced it has submitted its Aquarius electro-chlorination ballast water management system for US Coast Guard type-approval after successfully completing all the testing procedures required.

Wärtsilä received type-approval from International Maritime Organization in 2013 for the electro-chlorination system and the same successful design was used for the USCG application. According to Wärtsilä, the system has demonstrated a high level of reliability, robustness and effectiveness.

“Achieving this significant USCG testing milestone is a major step forward for the product. It provides customers with further assurance that this system efficiently addresses ballast water treatment compliance needs, with a reliable product and a partner committed to long-term global support,” said Wärtsilä director, ballast water management systems Joe Thomas.

The Wärtsilä Aquarius electro-chlorination ballast water management system utilises proven filtration and electro-chlorination technology, while maintaining a high degree of safety, operability and reliability. It ensures compliance with regulations, even with varying levels of water quality. Safety has been a fundamental consideration in the design, and hazard analyses aimed at eliminating installation and operational risks have supported its development. The Wärtsilä range of ballast water management systems are backed by Wärtsilä’s global service network.

Wärtsilä also offers a ballast water management system using filtration and ultra-violet irradiation. The Wärtsilä Aquarius ultra-violet irradiation system is type-approved according to the IMO Ballast Water Management Convention and has an Alternative Management System acceptance certificate from the USCG. It is currently undergoing full USCG type-approval testing with completion expected during 2018. The Wärtsilä Aquarius ultra-violet irradiation is also certified for installation in hazardous areas.
