Securing the world’s largest offshore windfarm with 长颈鹿1 x
A major expansion of national energy infrastructure is taking place not only in Europe, 但在世界范围内. It is predicted that offshore wind will be an important source of electricity for Europe, 它朝向 net zero greenhouse gas emissions by 2050. This will require rapid expansion of windfarms, which will have a significant impact on the coastal and offshore environment, on a scale that has not been seen before and therefore important to protect. This can be considered a vital step towards renewable energy capacity to enable transition to a fossil-free society.
In order to manage and secure the expansion of the large infrastructure commitments a solution must be found for the co-existence of air defence and offshore wind energy. This is essential to ensure that nations around the world can maintain their air defence and early warning capabilities while realising their full offshore wind potential and protecting their nation’s security interest.
Saab and the Danish company Ørst, known for its global business within renewable energy, tested an offshore radar concept with the 3D AESA radar system 长颈鹿1 x on the world's largest operating offshore wind farm Hornsea 1, 120 kilometres east of the Yorkshire coast in UK waters during September and October 2021. 测试, which were carried out with satisfactory results, were remotely managed from Sweden and monitored from Denmark by Saab, Ørst, 丹麦皇家空军, and the UK's NATS air traffic control. The goal was to mitigate the interference from offshore windfarms on the recognized air and maritime picture as well as to validate the performance in a coastal and offshore environment with parameters such as extreme weather conditions and the highest of wind speeds.
Promising environment for 长颈鹿1 x
Surveillance and early warning of a nation’s air space is crucial for nations to protect their citizens and critical infrastructure from airborne threats. Long-range air defence radars have been located on land sites for decades, on high ground with unhindered view of the sea to best make threat assessments. 雷达，如 4长颈鹿 continuously scan immense volumes of airspace every day 24/7, and detect airborne threats and anomalies. 在过去十年中, the impact of offshore wind turbines on air defence early warning radars has also been recognised. Offshore wind turbines are large, numerous and they move. Each blade is approximately 70-100 meters long and wind turbine blades might be even longer in the future. This movement of the blades is picked-up by radar and create unwanted clutter, reduction in performance and noise on radar screens. Offshore windfarms are moving further away from shore and the curvature of the earth is still a fact at the same time as the maritime environment and activities change.
Great leverage of small size
短程或中程, high-resolution offshore 3D radar can be a flexible and affordable solution, 长颈鹿1 x is a combination of operational flexibility, multitasking capabilities and multi-role use for tracking up to 600 airborne and other types of targets simultaneously. The system also offers an Enhance Low, Slow and Small (ELSS)-flying-target detection function. This technology and application enables and complements situational awareness in and around offshore wind farms and even beyond the radar horizon of the ground-based long-range radars.
然而, offshore wind farms do not only generate energy, but also increasing demand activities from vessels, helicopters and unmanned aerial vehicles (UAVs), which are needed for the construction, operation and maintenance of those wind farms. These activities need to be monitored for the safe operation of the offshore infrastructure, not least to support search and rescue services in their missions.
Coexistence of defence and offshore wind energy
The promising cooperation between Saab and Ørst is pioneering in the field of mutual coexistence. The trial results with 长颈鹿1 x in the world's largest offshore windfarm will be shared by both partners with relevant government stakeholders in the next phase. This is with the aim of enabling the acceptance of marine areas and specific projects by the authorities. 此外, a standardised approach will be developed to guarantee the coexistence of defence and offshore wind energy in the long term. 所有 this contributes to the further development of the knowledge and competence base regarding realistic requirements for offshore wind farms and their situational awareness among state actors, 包括武装部队.
