Both Polsteam and Novaship have selected the Alfa Laval PureBallast 3 system for thier fleets to comply with the Ballast Water Management (BWM) Convention.
The move by Polsteam to retrofit its entire fleet follows an investment in six PureBallast 3 systems in 2017, which are currently being fitted to vessels. The fleet wide deal will see the company owning 60 such systems with 16 systems handling 2000 m3/h or more.
“This was a key decision for Polsteam, based on long-term factors such as operating economy and supplier security,” said Grzegorz Wardzyński, director of the Technical Department at Polsteam. “The UV technology used by PureBallast 3 will be simpler and more cost-effective than electrochlorination, even for our very large systems.”
The deal with Nova Ship Tech will cover systems for 34 vessels with PureBallast 3 offering a high degree of flexibility the company needs for retrofitting across different ships.
“Intervening in the existing structures and systems of ships in operation is much more complex than a whole newbuild project,” said Francesco Costagliola, Nova Ship Tech technical manager. “Alfa Laval PureBallast 3 has a compact and highly flexible structure that facilitates installation as a retrofit. Above all, Alfa Laval has the field expertise and proven operating procedures to adapt it to any ship.”
Alfa Laval is noting a shift in behaviour among customers to fleet wide deals as the date for the implementation of the BWM Convention for existing vessels draws nearer.
“Leading actors like Polsteam and Nova Ship Tech are now pursuing ballast water treatment system retrofits in earnest,” said Anders Lindmark, Head of Alfa Laval PureBallast. “In light of recent directives from authorities, they are keen to secure not just the right technology, but also a stable partner who will be there to support them in the long term.”
