Subject: Seatools introduces automated mort collector for offshore fish farms
Message:
On behalf of its client De Maas SMC, Dutch subsea technology company
Seatools completed a feasibility and conceptual design study on a Remotely
Operated Mort Collector (ROMoC). The study resulted in a highly automated
mort collection system capable of effectively collecting dead fish in large-scale
offshore fish farms as currently developed by De Maas SMC.
In addition to innovative large-scale fish farm concepts, the trend toward
offshore fish farming also requires the development of related systems, such as
a fish farm cleaning system. This system facilitates efficient and reliable fish-
farming operations in hostile and remote offshore environments. By taking a
highly structural design approach, Seatools designed and evaluated multiple
potential solutions for the various functionalities required by a large-scale
offshore mort collection system. A key requirement – a 100% coverage of the
fish pen surface within a 24-hour time span – was of critical importance during
the design process. By extensively drawing on in-house knowledge of subsea
equipment design and subsea navigation and positioning, a well-considered
mechanical design resulted. The design is backed by a self-positioning control
algorithm to ensure the entire pen is covered within the given time limit.
In addition to the pen coverage design criterion, several other key criteria had to
be met. Niels Haakman, project manager, comments: “Next to a 100%
coverage of the fish pen surface, the concept had to have a minimal impact on
the operations and design of the offshore fish farm. This meant the system had
to come with a minimum footprint, weight, and required installed power. By
relying on simple and effective principles as well as an advanced control
system, we were able to keep the design compact and lightweight.
Furthermore, the design’s burden on the farm’s primary operations and setup
are kept at a minimum. Which is expressed by – among others – the fact that
the collector can run without requiring any operator attention for up to 12 hours
on end.”
