Nanobubble technology sets new standard for wellboats
Wellboat operator Rostein has implemented nanobubble technology from
the American company Moleaer, with the results showing both improved
oxygenation and significant environmental and cost benefits, Fish Farming
Expert’s Norwegian sister site, Kyst.no reports.
The technology, tested on Rostein’s wellboat Ro Fjell, is based on the
production of nanobubbles. Where large bubbles rise quickly to the surface
and release the oxygen before it can be used, nanobubbles are so small that
they remain suspended in the water for a long time, thus utilising the oxygen
far more efficiently than traditional methods.
The test results indicate a potential reduction in operating costs of up to 80,000
euros annually.
According to Rostein, nanobubble technology also offers greater flexibility. The
system can either be used to reduce energy consumption per kilogram of fish,
or to increase fish density in the holds – as long as it is done within current
welfare standards.
At the same time, the need for maintenance and spare parts is reduced, which
contributes to a lower overall burden, both financially and environmentally.
The technology has also been adopted by the shipping company Betveit Holdings.
Experience suggests that nanobubble technology could become an important part
of the toolbox in the future for more sustainable and efficient transport of live fish.
