Aker BioMarine has launched an unmanned solar-powered ocean data drone (Sailbuoy) in order to collect detailed data on krill biomass in the Southern Ocean.
The new remotely operated vehicle (ROV) is part of the Norwegian company’s operations in Antarctica to take a further step in a new data-driven era of sustainable fishery and fishery management.
Equipped with echosounder and environmental sensors, the two metre long data drone collects, processes and transmits density and distribution data from wherever it is deployed, in real time.
Easy to operate, launch and recover, the unique ocean drone uses wind for propulsion while the electronics are powered by solar panels, which charge the internal batteries. The Sailbuoy can reach a speed of 2 knots (approximately 2.4 nautical mph).
Built to be robust and to survive the tough Antarctic conditions, the ROV has also been designed to be small and unobtrusive, so that it does not disturb the local wildlife.
We position it close to the vessel and it does the searching for us
Minimising the need for fishing vessels to spend time and resources looking for krill, the use of the ocean data drone significantly reduces the financial and environmental costs of searching for krill. All the data collection carried out by the drone has a carbon footprint of zero.
Frank Grebstad, SVP Vessel Operations said: “Finally deployed, after a number of years in development, the Sailbuoy is changing how we work. We can position it close to the vessel and it will do the searching for us, or we can let it cover remote areas for up to months at a time, telling us where and when to proceed.”
He added: “As our Antarctic eyes and ears, the data the ocean drone is collecting is proving absolutely invaluable, and it is enabling us to make our operations even more sustainable and more focused, further lowering our impact.”
The company behind building the Sailbuoy, Offshore Sensing is pleased to put the ocean drone in practical use in the tough conditions of Antarctica. David Peddie, CEO Offshore Sensing said: “Albeit small, the Sailbuoy is designed to make a major impact when it comes to improving efficiency and helping the companies make better decisions based on real-time data. This Sailbuoy will help Aker BioMarine enter a new data-driven era of sustainable fisheries.”
In addition to operational gains, the data will be of enormous benefit in the long-term to the wider scientific community and the krill fishery as whole.
The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the international treaty managing the krill fishery in the Southern Ocean, has made decisive steps towards a more dynamic and scientific data-driven management regime, which will put a lot of responsibility on the industry’s capability to monitor the krill biomass.
The ocean data drone technology will enable the krill management regime of the future to come sooner rather than later.
With the careful management of the fishery by precautionary catch limits based on frequent estimates, the detailed data that Aker BioMarine now can capture on density and distribution, will provide a more accurate picture of the size of the biomass. This will help the industry to better guide decisions on this precious resource in a time of climate change and with increasing needs for knowledge and data.
