北极离岸农业正在使用基于离岸技术的遥控和潜水鱼笔开发一个新的鲑鱼耕种概念。ABB将对电气，自动化，仪器和电信解决方案负责全面的系统责任。
北极离岸农业是挪威皇家鲑鱼（NRS）项目。NRS已获得7.68个开发许可证，可在养鱼场的位置总共提供多达5990吨鲑鱼。
恶劣的环境
The offshore farm consists of two large fish cages that are placed in the Norwegian Sea outside Troms, in an area where weather and wave conditions are far more demanding than inside the fjords, where traditional farms are located.
Placing the farm offshore reduces its environmental footprint, while providing an opportunity to study if this can provide a healthier environment for the fish. But the harsh climate also means stricter safety requirements are required. ABB will be responsible for designing the monitoring and control systems that will make it possible to operate the plant safely. This means, among other things, that there are back-up solutions, or redundancy, in critical systems such as energy supply and communication.

对稳定的高需求
Pontoons over and under the fish pens will keep the pens in place in two different positions. In the service position, the facility is lifted to allow access to the equipment. In the normal operating position, the roof of the cages will lie 10 meters below the sea surface. This will result in reduced lice impact, while at the same time lowering the risk of escape.
In ballasting and de-ballasting (raising and lowering), the fish pens will be partially submerged.
Among the most critical systems are the pontoon ballast water systems, designed to ensure that the pens are stable. ABB will deliver the control system with sensors, monitoring, automation and interfaces for the remote control of the pumps. The harsh climate in the Norwegian Sea presents challenges with fouling and icing, which will cause time-varying weight changes challenging the constructions ballast system supplied by ABB.
广泛的数据收集
该系统还收集环境数据，包括作为气象条件，洋流，氧气和海温。它还在不同深度和笼子中的生物质量下监视pH值。
“授予开发许可证的目的之一是为当今行业所面临的一些挑战找到解决方案，以便它可以继续以可持续的方式发展。笔将无人驾驶并在淹没操作中运行。鱼笔是从距钢笔约400米的进料驳船中进行远程控制的。从技术上讲，养鱼场可以很容易地从陆地上的控制室管理” ABB销售专家（水产养殖）Lars Wasa Andersen说。
ABB is working to be the most valuable partner within electrical, instrument, automation and telecom systems for aquaculture customers to help improve efficiency, environmental impact and productivity across the value chain, including enabling new solutions for fish farming offshore and onshore. Fish welfare, traceability and food safety are key focus areas of ABB’s support.
“The contract fits perfect with ABB’s vision regarding aquaculture. With this project, ABB is entering as a supplier to the future offshore fish farms, which places new demands on both safe operation and technical solutions. ABB has total responsibility for technical solution within several disciplines”, says Steffen Waal, country manager of ABB Norway.
整个解决方案将在第3季度2020年底之前实施。
