The C bud
The C Bud represents an effective and least destructive large scale method for harvesting marine species from the seabed and opens for harvesting in areas where traditional methods have not been possible.
The C Bud is a tracked platform capable of harvesting benthic species in its full width, filtrating the bi-catch and putting this back instantly and unharmed to the seabed, before sending the harvested species directly to the vessel for further storage or processing.
The C Bud has proven itself to be just as effective as traditional seabed dredging yet being far gentler to both the harvested species, the bi-catch and the seabed.
The C Bud focuses on efficient and gentle harvesting with as minimal interaction with the seabed as possible and the C Bud represents the first true alternative to traditional methods as seabed dredging.
Key advantages for the C Bud:
- Highly efficient.
- Leaves small footprint on the seabed/minimal impact on the seabed.
- Adjustable for optimal catch and minimal bycatch.
- More controlled and more environmentally friendly than conventional methods.
- Remotely and easy operated.
- No damage to the species harvested.
- Robust and low maintenance.
- Equipped with positioning system, several cameras, and light, for monitoring both seabed and harvesting process.
- Detect obstacles and avoids them.
- Reduces vessel fuel consumption, and emissions.
- Customizable for a range of other tasks.
- Scalable to fit the size of a boat/vessel.
- Can also be used in other segments such as environmental work, ocean clean-up, or simply monitoring.
The C Bud is tested by Akvaplan-niva AS (Norwegian Institute for Water Research) and NOFIMA in Norway.
Highlights from the reports:
- The C Bud unit performed very well in harvesting both Icelandic scallop and sea cucumber. The post catch survival rates were good.
- C Robotic’s C Bud proved to be effective in harvesting Icelandic scallop with good catch rates in relation to the effective running time.
- The numbers from trial estimated the C Bud to be capable of harvesting over 16.000 scallops per hour.
- Compared with bottom scraping equipment that otherwise is used for scallop fisheries, the C Bud appears to have a far lesser impact on the bottom habitat.
- Non-target organisms were largely undamaged.
- Based on the field observations, it is unlikely that the C Bud will cause excessive pressure on the seafloor, or cause habitat destruction.
- We find it unlikely that the C Bud had left notable track-marks across the maerl habitat.
- Most of the larger bycatch is considered to have a high likelihood of survival.
- Sea cucumbers appear to be able to cope with harvesting by the C Bud, followed by transport and live storage (up to 47 days).
- The trial showed that the C Bud was a very efficient means of collecting sea urchins (and other benthic invertebrates) from a flat seafloor.
- The trial showed that urchins collected by the C Bud have a good survival rate. The urchins collected would be suitable for both immediate sale as well as holding in land or sea-based systems for roe enhancement.
Statement from NOFIMA after test.
“The Harvesting Device” shows tremendous promise as a harvesting technology suitable for benthic invertebrate species (such as sea urchins, sea cucumbers, scallops) found on flat substrates. In addition, it has clearly demonstrated its suitability for providing a suction system capable of removing silt and sludge from the seafloor. This has tremendous application potential in sea-based aquaculture.”
“The Norwegian Directorate of Fisheries has granted a license to harvest Clamys Islandica (Island Scallops) to Safe Offshore AS. The license granted, is based on extensive testing and verification by independent surveyors regarding the C Buds non-destructive and sustainable harvesting method.”
