2 Power Requirements
2.1 Power at 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.
...
| Info |
|---|
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
3.1 Barge local network

If the internet subscription has a monthly limit for traffic; the Bluegrove services needs 100 GB a Month.
Alternative 1 - Use the customer's VPN
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.
...
3.2 Managed networks
For a detailed requirements for operating in customer managed networks see this page. [Private]https://bluegrove.atlassian.net/wiki/spaces/TRB/pages/1305903173/Bluegrove+Cybersecurity+practices#Operating-in-customer-managed-networks

4 Integration Requirements
4.1 Operational feeding system integration
The customer must to provide Bluegrove with an integration to his feeding system. Bluegrove maintains this list of compatible feeding-systems: Feeding-system integrations and compatibility with Bluegrove

What happens if the requirement is not met: Feeding service is interrupted. Data collection on feeding is interrupted. |
4.1.1 For developers: General feeding system integration requirements
...
| title | 3.1.1 General feeding system integration requirements and definitions |
|---|
Feeding system requirements version 0.0.6.
This section defines general requirements for controlling a feeding system for sea-based and land based aquaculture.
Intention
Enable the fish farmer to:
Maintain high uptime of its feeding processes.
Safely enable interaction between applications while minimizing risk of service outages.
Procure, replace or remove software from any vendor in a modular way.
Maintain high data and operational security
Get early warning about errors and the possibility of investigation through logging.
Enable access on an individual level, and integrate with the company's user directory.
Maintain robust local feeding operations with unreliable internet.
Enable remote control of feeding operations at different sites with full functionality without the use of VPN.
Enable control of feeding operations on one user interface, regardless of feeding system vendor.
Enable frequent and high-resolution data collection from feeding operations.
Safely control feeding operations remotely with no or unstable internet.
Enable scale in the data collection by using good practices like “Report by exception/change” and avoiding polling.
Definitions
...
Unit: The unit where feed is dispensed to the consumers. Example: Cage or tank used in aquaculture.
Feeding system: The machinery/installation which executes the feeding. Feeding barge at sea. Example: Land based feeding installation.
Feeding control system: The industrial control devices controlling the machinery in the feeding system. Example: The PLC controlling the feeding system. The server controlling the PLC.
Feeding Line: The feeding system internal feeding line. in the control system. Feedlines can sometimes be routed to different pipes by "changers". Example: Feeding line inside a barge connected to a blower and one or more feed silos.
Pipe The pipe or conveyor to transporting the feed from the feeding system to the place where it will be consumed. Example: The feed pipe from a barge to a cage.
Out of scope features
Feeding tables. A plan for dispensing feed over time. Often provided by the Feeding control system or feeding application.
Automatic feeding. A configurable plan for dispensing feed over time which is executed by the feeding system. Often provided by the feeding control system.
Biological data. Data on species, number of fish, weight, mortality etc. Often provided by the Feeding control system, ERP or planning tools.
Calibration of feeding dosers. Calibration of dosers to dispense the correct amount of feed. Often provided by the Feeding control system.
Line configuration. An operation that moves a pipe from one cage to another. The operator then updates it in one system, which then makes it available to other systems by API. Often provided by the Feeding control system.
Dosing of feed. The industrial control system achieves the desired intensity by operating the dosing machinery. Often provided by the feeding control system.
Silo management. Used for selecting type of feed. Often provided by the Feeding control system.
Required functionality:
...
Feeding Mode
Enables switching between manual and automatic feeding.
...
Set Intensity
Sets the feeding intensity for a pipe.
...
Alarm Warning Or Stop Message
Alarms, Warnings, or stop messages from the feeding control systems.
...
Feeding Lines Avaliable
Lists the available units(cages) avaliable to each feeding line, by changer or directly connected.
...
Enable And/Or Change Feed Line To Conveyor
Operates the changers to connect one line to the selected pipe.
...
Feedline Status
Describes which pipe(cage) the feedingline in the feedingsystem is connected to. Also gives the status of the feedline.
...
Feedline Blower Level
The set power of blowing in percent from maximum of 100%. 0 when off.
...
Feedline Pressure
The pressure inside a feedpipe.
...
Feedline temperature
The temperature inside a feedline.
