Raytec are world leaders in LED lighting for hazardous area environments. SPARTAN is our range of globally certified Ex LED luminaires, delivering class-leading performance and reliability. In this Application Focus we look at Ex lighting requirements for ports and terminals and identify some of the key features to consider when specifying luminaires for these environments.
Why Ex Lighting is Needed for Ports
The nature of port applications, and their coastal location, provides a challenging environment when specifying lighting. A luminaire capable of withstanding the elements is essential, given that it will commonly be exposed to marine conditions (often not too dissimilar to that of an offshore application).
Furthermore, major ports that act as a hub for imports and exports will likely have a significant amount of hazardous substances (such as oil and gas products, but also bulk grains which carry an explosion risk) passing through on a daily basis, or being held in storage facilities on-site. Port owners must therefore ensure the site is compliant by having the necessary equipment on-site to safely handle and store these substances; this is where hazardous area lighting becomes so important.
Typical areas around a port requiring Ex certified lighting includes;
Docking Areas – this is where tankers or cargo ships will discharge. Discharging of explosive substances, such as crude oil or LNG (Liquefied Natural Gas),
means that using explosion protected equipment on and around the docks is critical. With operations happening 24 hours a day, safe and effective lighting
solutions are vitally important.
Specifying Lighting for Ports
The benefits of LED over conventional lighting technology are well documented but are especially relevant for port applications.
Lifetime and Maintenance
Capable of 100,000+ operating hours, without the need for re-lamping, LED offers significantly longer lifespan and reduced maintenance in comparison to conventional lighting. For busy ports operating 24 hours a day, where access to light fixtures on docks and storage facilities can be challenging, this is a major benefit.
Like many industries, ports and terminals are under increasing pressure to reduce light pollution to help protect the nights sky and reduce the impact on local wildlife. The directional nature of LEDs can help significantly with this problem, ensuring light is only directed where needed.
With typically higher colour temperatures, and improved colour rendering compared to conventional lighting, the installation of LED luminaires can help to have a significant impact on working conditions within the port, and ultimately improve overall efficiencies.
Reducing energy costs is a constant challenge for the ports sector. Installing LED luminaires in areas such as grain stores is extremely beneficial for the end user. With conventional lighting, users tend to leave the lights switched on permanently. This is as a result of the warmup time that the luminaire needs to restart. With LEDs, there is an instant light output when required, so the luminaries can be turned off when not being used. Not only does this reduce energy costs, it prolongs the life of the luminaire.
