will be partially submerged.
Among the most critical systems
are the pontoon ballast water
systems, designed to ensure that
the pens are stable. ABB will deliver
the control system with sensors,
monitoring, automation and
interfaces for the remote control of
the pumps. The harsh climate in the
Norwegian Sea presents challenges
with fouling and icing, which will
cause time-varying weight changes
challenging the constructions
ballast system supplied by ABB.
Extensive data
collection
The system also collects
environmental data including as
meteorological conditions, ocean
currents, oxygen level and sea
temperature. It also monitors the
pH at different depths and the
amount of biomass in the cages,
amongst others.
“One purpose of awarding a
development license is to find
solutions to some of the challenges
the industry has today so that it can
continue to grow in a sustainable
way. The pens will be unmanned
and operate in submerged
operation. The fish pens are
remotely controlled from a feed
barge that lies about 400 metres
from the pens. Technically, the fish
farm can just as easily be managed
from a control room on land,”
says Lars Wasa Andersen, sales
specialist (aquaculture) at ABB.
ABB is working to be the most
valuable partner within electrical,
instrument, automation and
telecom systems for aquaculture
customers to help improve
efficiency, environmental impact
and productivity across the
value chain, including enabling
new solutions for fish farming
offshore and onshore. Fish welfare,
traceability and food safety are key
focus areas of ABB’s support.
“The contract fits perfect with
ABB’s vision regarding aquaculture.
With this project, ABB is entering
as a supplier to the future offshore
fish farms, which places new
demands on both safe operation
and technical solutions. ABB has
total responsibility for technical
solution within several disciplines”,
says Steffen Waal, country
manager of ABB Norway.
The entire solution will be in place
by the end of Q3 2020.
