Guide to selecting lighting for offshore wind energy applications

Lighting for offshore wind energy applications

Offshore wind farms present a lighting challenge as they are constantly exposed to salt, wind and water. You need to specify a quality, heavy-duty fixture to withstand these conditions. lighting for one offshore wind farm must take into account a number of important considerations. These include:

Selection of light-emitting diodes

Offshore wind farm lighting should prioritize LED technology over more traditional options such as high-pressure sodium (HPS) lamps.

  • The maintenance of the lighting

An LED light can last 100,000 hours or more without changing the lamp if it has good thermal management. A High Power LED Supplier offers you a longer service life and reduced life cycle costs. It is crucial to reduce maintenance interventions in these hard-to-reach and expensive-to-reach offshore areas.

Keeping costs down is a common goal in offshore wind applications. use LEDs less energy than lightbulbs, saving money on utility bills. The ability of the LED light to restart instantly is the most important feature. The lights can be quickly turned on and off when not in use with the instant restrike feature. Traditional lamps (like high-pressure sodium) would likely be left on 24 hours a day to avoid costly and inconvenient delays during maintenance due to their long warm-up times.

The quality of light in the workplace is significantly improved due to the higher color temperatures and better CRI of LEDs compared to conventional lighting.

Easy maintenance

Choosing LED lighting can help reduce the time and money spent on maintenance. However, the design of the luminaire by the manufacturer can have a significant impact on ease of maintenance. It also affects how long you leave the site in the dark.

An LED light with a detachable power supply unit (PSU) positioned independently of the central unit can improve Maintenance access in offshore wind farmswhere access can be problematic.

  • Minimize service disruptions

Downtime is critical to wind farm profitability. You cannot perform certain periodic maintenance if the lights are out for fear of endangering the health and safety of staff. This can affect turbine uptime. Maintenance-friendly lighting can therefore be a major selling point for manufacturers, developers and investors, as it increases the overall financial viability of the site and allows the facility to be back up and running as quickly as possible.

durability

It would help to consider many environmental concerns when building equipment for offshore wind farms. When considering durability, consider the following:

  • Seawater (saline environments)

Corrosion is more likely to occur in salty environments than in freshwater. Metal is quickly corroded by salt water splashes. After the seawater has evaporated, a small layer of salt may form on the fixture’s hardware, reducing the light output of the fixture. Installations in these harsh offshore regions require luminaires that can withstand extreme temperatures and pressures.

Make sure you choose a light fixture made from marine-grade aluminum or stainless steel, as these materials are more resilient to harsh weather. You can minimize water ingress into the fixture by choosing a model with a smaller front seal.

  • Extreme weather and wind speeds

Typical for offshore applications are high wind speeds and weather conditions such as sleet, hail and heavy rain. A luminaire with a high IP rating is required to prevent water damage to the internal components of the device. The mounting points and brackets for the lights must also be strong enough to carry the additional wind loads. Otherwise, the lighting bracket may wear out and break, resulting in the device being lost at sea. Choose a luminaire with an appropriate IP rating and check the specific tests that the luminaire has undergone.

UV (ultraviolet) radiation exposure is common in offshore locations that are exposed to the sun for long periods of time. With an offshore wind turbine, nothing obstructs the view of the turbine. Depending on the material from which they are made, UV exposure can cause problems with certain luminaires when the lighting is installed outdoors, e.g. B. in the “Jacket Base”. For example, GRP (glass fiber reinforced plastic) luminaires can break down and become brittle with prolonged exposure to UV radiation, leading to structural and maintenance problems.

When it comes to specifying lighting for an offshore wind application, lighting design is a critical element of the process. Make sure you know what to look for. Your top priority should be making sure your money is well spent.
