Aquarius BWMS put forward for USCG type approval

Mar 29 2018

Wärtsilä has submitted its Aquarius electrochlorination (EC) ballast water management system (BWMS) for US Coast Guard (USCG) Type Approval (TA) after successfully completing all the testing procedures required.

The company received type approval from the IMO in 2013 for the system and the same successful design was used for the USCG application.


“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 Joe Thomas, Wärtsilä’s director, Ballast Water Management Systems.


The Wärtsilä Aquarius EC BWMS uses proven filtration and EC 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 company claimed.


The range of ballast water management systems is also backed by Wärtsilä’s global service network.


Wärtsilä also offers a BWMS using filtration and ultra-violet (UV) irradiation. The Aquarius UV system is type approved according to the IMO Convention and has an Alternative Management System (AMS) acceptance certificate from the USCG. It is currently undergoing full USCG TA testing with completion expected this year.


The Wärtsilä Aquarius UV is also certified for installation in hazardous areas (EX).
