In short
Stable power on the cage and barge
Stable internet
Detailed requirements
These requirements define the optimal environment for Bluegrove systems. If any of the requirements are not met the Bluegrove service will be impacted as described in each point.

1 Physical requirements
1.1 Limitations in use/performance with other specific components
Main components
Component | Problem | Solution |
|---|---|---|
Cage type: | (2).png?version=1&modificationDate=1687513209497&cacheVersion=1&api=v2) Conflict between the top bracket fixture and the handrail post. | Use stainless ratchet straps or rope to tie the top part of the bracket to the pole. |
Extra equipment
Component | Problem | Solution / Løsning |
|---|---|---|
Aeration devices that makes airbubbles inside the cage. Sold under names like(Midt-Norsk ring, Turbolift etc) | The echosounder picks up the bubbles and it creates a noisy image of the fish. | Echosounders are not compatible with aeration devices. |
Aside from these components, the equipment is compatible with any other component that is not directly interfering with it. It is compatible with predator nets.
1.2 Cage requirements
Minimum 15m deep nets, which gives a 13m sensor head distance.
1.2.1 Coverage for different cage sizes:
Cage type | Estimated total coverage |
|---|---|
 160m circumference | ~ 40% |
 120m circumference | ~50% |
 130m circumference | ~80% |
 Square 40x40m | ~25% |
 Square 30x30m | ~30% |
 Square 25x25m | ~50% |
Performance is mainly affected by how well the sensors cover the feeding zone.
1.5 Operational feeding system with integration.
Bluegrove is compatible with these feeding systems. The blowers, dosing, changers, piping, feed spreaders need to be in working condition.
What happens if the requirement is not met:
You will not get feeding data and you might not be able to feed.
2 Power Requirements
2.1 Power at barge
The CageEye system requires 2kW @ 230V 50hz at the barge.
The system complies with the international EMC standards: IEC/EN 60950-1, IEC/EN 61000-3-3, IEC/EN 61000-6-1 and IEC/EN 61000-6-3.
In case of power source problems such as noise, spikes, brownouts and blackouts, an Online UPS system needs to be installed to accommodate continuous power stability and availability.
What happens if the requirement is not met:
Service stops as soon as the power to the server and antenna is broken. This is mitigated by using a UPS(battery).
2.2 Power at cage
Estimated continuous power requirements for all sensor devices in cage: 60 W
Estimated maximum power consumption in the future 500 W
The CageEye system requires 60 W @ 230V 50hz outlet at the cage. The power supply must have a 3-16A fuse.
What happens if the requirement is not met:
Service stops as soon as the power is interrupted. This is mitigated by using a UPS(battery).
3 Network Requirements
Bluegrove uses two operating models. Customer managed network, and unmanged network.
3.1 Unmanaged networks
Bluegrove will install a server on the barge that needs to be on the same network as the feeding systems and the feeding cameras. Remote connections to operations centers can be set up in cooperation with the customers technical staff. Bluegrove needs to use radios to communicate with the sensors on the cages.

3.1.0 Ports used by the CageEye server
Type | Port | Used for | Traffic |
TCP | 1194 | Communication through OpenVPN with CageEye cloud servers; and remote servicing. | Incoming and outgoing |
What happens if the requirement is not met:
Dataflow and remote services are interrupted. Data is buffered for some time until recovery.
3.2 Managed networks
