WELLBOATS – THE BENEFITS OF UV LAMP-BASED DISINFECTION SYSTEMS
We take a deeper dive aboard Wellboats, the increasing use of disinfection systems on vessels serving the aquaculture sector to transport livestock safely and why UV light is a better solution for the growing industry feeding an ever-growing population.

aquaculture sector is a booming industry, and as farmed fish are a key part of
the world's food production; the industry relies on being able to transport
fish stock from farms for re-location, delousing and processing. Wellboats utilise
a storage space full of water in the middle of their hull. This ‘well’ typically
uses a recirculating aquaculture system (RAS) for ongoing filtration and
removal of suspended matter and metabolites to keep the water clean and provide
a healthy environment for the fish to live in.
disinfection systems – how it works…
RAS can use various ways to keep a wellboat water clean but one of the more
popular ways is via ultraviolet light technology. When water is taken onboard,
the disinfection system processes the seawater with a powerful dose of UV light.
UV light eliminates pathogens in the water allowing for the livestock to be
housed and transported safely, without risk of chemical or viral contamination.
Why ultraviolet light is a better solution.
UV technology has progressed, its application in the aquaculture industry and ships
like wellboats is a viable solution to existing problems that many marine
vessels face. Medium-pressure lamps used in disinfection processes are
relatively small which is beneficial when the use of space is at a premium,
especially if a ‘retrofit’ is needed in an older vessel. This size advantage in
itself is much less costly than the need for an entirely new ship or a complete
redesign/installation of its form and function.
challenges associated with disinfection processes that are chemical based are
no longer a concern with the use of UV technology. UV can render microbes
inactive that have developed a resistance to chemical treatments over time, the
process also produces zero chemical by-products in the water or stock and
reduces chemical handling for the crew of the wellboat. Overall, the installation,
use and maintenance of a UV-based system are much more efficient, safe and
simplified, compared to a chemical-based solution.
reason why utilising a UV-based disinfection system for the wellboat industry
is becoming widely implemented, is due to the disinfection process not
influencing key water properties, such as temperature, pH, and oxygen levels.
This further compliments the optimal conditions for the transported fish.
the wellboat - how UV can benefit business, industry, and the planet...
can use UV lamps to help purify not only the housing water for the fish, but
the technology also allows for the discharge of clean and hygienic ballast water
back into the sea without cross-contamination for species, ecosystems, and the planet.
Businesses and the aquaculture industry could grow and prosper by embracing UV light-based
systems on wellboats and beyond because of the benefits demonstrated. The
technology also enables fish farms to grow by:
- Increasing stock densities
- Destroying the bacteria or viruses that cause illness
- Reducing mortality rates
- Transporting safer, more efficiently, more often, with
less risk of disease to wild livestock and sea waters.
