The world’s most prestigious luxury yacht is equipped with a BIO-SEA ballast water treatment system from the BIO-UV Group of France as reported by Marine Link.
A critical concern
Christina O, the 1943-built motor yacht named after the only daughter of Greek shipping magnate Aristotle Onassis, was fitted with a low-flow BIO-SEA system last year as part of a major refurbishment at the D.K Fotinakis yard, in Greece.
To fit the limited space available in the 325ft long vessel’s machinery room, the 87m3/h capacity BIO-SEA L03-0087 system was supplied on two separate skids – one housing all mechanical components, the other the system’s electrical works.
“System size was a critical concern,” said Costas Carabelas, Managing Director, Costas Carabelas Technical Office (CCTO), the naval architect and engineering firm responsible for yard and equipment selection, engineering and installation.
“This ship is like a museum, so any new installations had to fit in the existing space without requiring any significant structural change.”
Dismantling main components
The French manufacturer suggested a plug-and-play, split skid version of its BIO-SEA L-Series as this allowed CCTO’s technical teams to dismantle the main components to easily pass through the hatches without cutting holes in the vessel.
The BWTS was rebuilt in-situ, in the engine room.
“The level of service provided by MACOR during the commissioning was excellent,” Carabelas said.
The BIO-SEA system is operating as expected; performance is excellent.
It is very simple to operate, and the yacht is now compliant with the IMO D2 standard and the USCG regulations.
Increased demand
Franck Perier, the technical supervisor leading BIO-SEA by BIO-UV Group’s service department, said, “This is a very famous ship and the testimony received reflects the positive feedback we get from all operators of a BIO-SEA system.”
“There is certainly increased demand for low flow rate BWTS for retrofit and newbuild yacht projects.”
The Ballast Water Management Convention entered into force in September 2017 and applies to all vessels that take up and use ballast water on international voyages.
With flow rates ranging from 10m3/h to 120m3/h, the Low-Flow BIO-SEA range can be available with CuNiFe pipework for enhanced corrosion protection and in a range of gloss finishes.
Additional upgrades include a new PLC with a more compact, touch screen and control cabinet.
Additional power cabinet
Florian Cortes, Technical Director, BIO-SEA by BIO-UV Group, said, “We have enhanced the system specifically to meet stringent yacht sector requirements. In addition to size and ease-of-use, the BIO-SEA L range negates the need for an additional power cabinet.”
“We have also been able to reduce the number, size and length of UV lamps without impacting treatment performance. By continually developing UV water treatment technology we can meet our yachting customer’s high expectations.”
