(LUND, Sweden) — Alfa Laval has signed fleet agreements with Polsteam and Nova Ship Tech SA for the supply of PureBallast 3, the third generation of Alfa Laval’s ballast water treatment technology. Under the agreements, Alfa Laval will provide dozens of Polsteam and Nova Ship Tech SA vessels with PureBallast 3 systems – the vast majority of which will handle large flows of more than 1,000 cubic meters per hour (m3/h).
The agreements with Polsteam and Nova Ship Tech SA come as many shipowners shift their focus from individual ballast water treatment systems to complete fleet solutions. Over the past year, clarifications of the ballast water management legislation have made it easier – and more important – to maintain a wider, more long-term perspective.
“Leading actors like Polsteam and Nova Ship Tech SA 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.”
Polsteam’s fleet agreement expands upon a previous investment in PureBallast 3 systems that the company made in mid-2017. With the installation of those six systems currently underway, Polsteam has now chosen to equip the rest of its fleet with PureBallast 3 – bringing its total ownership to 60 systems. All systems will handle large flows of at least 1,000 m3/h, with 16 systems handling 2,000 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. But it was equally important to choose a supplier who could deliver now and still be there to support us long into the future.”
For Nova Ship Tech SA, whose fleet agreement covers ballast water treatment systems for 34 vessels, the high flexibility of PureBallast 3 was a major factor in the decision. PureBallast 3 can be implemented smoothly, despite the variations that exist when working across a fleet.
“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 SA 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.”
