Wärtsilä reports a number of recent contracts to supply its Aquarius UV Ballast Water Management System (BWMS) for newbuild ships ordered by global operators.

The systems will enable the vessels to be compliant with the Ballast Water Management Convention regulations that entered into force in September 2017 for all new build vessels. The contracts cover in total 13 systems.

The work is being carried out for ships being built at yards in China. The orders cover installations in a ro-ro ferry, two ro-pax, six tankers and four container vessels. The company adds that in addition to the demand for new build installations, owners are increasingly requesting quotations for their existing fleet. For a vessel to be compliant with the IMO's Ballast Water Management Convention, owners have to install a BWMS at the next special survey of the vessel after 8 September 2019. This essentially gives a five year window for retrofits between September 2019 and September 2024, depending on when the special survey is due.

“This continued strong demand is a very positive verification of the efficiency, reliability, and robustness of the Wärtsilä Aquarius systems. Owners around the world recognise the fact that our BWMS solutions, which are backed by Wärtsilä’s extensive global service support network, provide assurance that their vessels can fully comply with the regulations, even with varying levels of water quality,” said Arto Lehtinen, Director, Water and Waste, Wärtsilä Marine.

The Wärtsilä Aquarius UV (Ultra-Violet) BWMS has completed all required testing procedures and has been submitted for US Coastguard (USCG) Type Approval. This follows IMO Type Approval for the Aquarius UV system, which was granted in 2012. The USCG approval process is extensive and involves both land and sea testing. The company’s other BWMS technology, the Wärtsilä Aquarius EC (Electro-Chlorination), was granted USCG Type Approval in August 2018, and IMO Type Approval in 2013.
