Aircraft Detection Lighting Systems provide reliable, continuous 360-degree radar surveillance of the airspace around wind farms, both onshore and offshore, communications towers, power lines and installations that require aircraft obstruction lighting, automatically issuing signals to activate obstruction lighting when aircraft are detected at a defined outer perimeter. Read more about ADLS in the article written by DeTect on page 7.

The Front Cover

Lightning damage stubbornly remains a major O&M expense for owner-operators in cost and frequency. Damage such as blade skin punctures, shell delamination, split trailing edges, and (less frequently) catastrophic damage to wind turbine blades is costly to repair and causes undesirable downtime. Arctura has developed a wind turbine blade coating that reduces lightning damage to turbine blades by encouraging surface flashovers (see page 7). (cover image: courtesy NTS Lightning Technologies).

Inspecting wind turbines is not just about flying around the rotor blades and gathering high resolution pictures of everything. It is about image quality and supplementary metadata that improve the overall value of, and information about, an inspection flight, and processing and presenting the results in a manner that allows rotor blade experts to make precise decisions. You can read more about this topic in the article written by Christian Raml from Aero Enterprise on page 7.

The Front Cover

As wind turbines installed in the late 1990s and early 2000s begin to be decommissioned, it is important to consider sustainable options for handling their end-of-life materials. Recycling and other circular economy methods can reduce the material intensity of wind energy production, but composite blades are more difficult to recycle than many other major wind turbine components.

The Front Cover

A recent project has investigated the potential for a renewable energy solution to reduce the emissions associated with the production of offshore oil and gas in the North Sea in a variety of scenarios. The project explored technical, economic and regulatory aspects of combining the offshore renewable energy and oil and gas sectors. The cover picture shows a Floating Power Plant basin test at Aalborg University, Denmark. In the article on page 7 you can read more about this project.

The Front Cover

An industry collaboration has developed a ‘Complex Flow Solver’ (CFS) that combines 50-point continuous wave lidar measurements, high-resolution open source computational fluid dynamics (CFD) modelling and powerful cloud computing to deliver the best available solution for bankable wind resource and energy yield assessment based on standalone lidar. The project has benefited from Horizon 2020 funding from the European Union. In the article on page 6 you can read more about this project.
