The EnviroLight towers have been developed in response to calls for a clean, ecologically safe lighting solution for use in environmentally sensitive areas such as Western Australia's Barrow Island where Coates Hire West will make 18 of the new towers available to contractors engaged in the $50 billion Gorgon liquefied natural gas project.
It's a huge gas project in one of the most beautiful places in the world. A new light design will help protect the local turtle population. Set to become Australia's largest resource project, the Gorgon venture will develop the vast natural gas reserves situated 60 kilometres north of the development's Barrow Island base.
Known as Australia's Ark because the Class-A nature reserve holds mammals that are rare, if not extinct, anywhere else in the world, the island is one of the world's top breeding grounds for sea turtles.
Studies have shown that turtles are dramatically disorientated by artificial light; which makes it harder for them to reach the sea quickly from their beach nests.
High bright light from industrial projects is known to be particularly attractive to vulnerable hatchlings, often making them move in the wrong direction. Delays in their journey to the water can result in death from exhaustion and dehydration as well as from predation as their natural enemies have the time, and the light, to find them.
In lighting experiments conducted on Barrow Island in 2005, Murdoch University researcher Kellie Pendoley proved that the type of light used affects the level of disorientation, and that sodium vapour lights had less potential to disorientate hatchlings than fluoride or metal halide light sources.
Because the system uses sodium vapour lighting instead of the usual metal halide lamps, and so produces a softer luminous glow than a piercing white glare, EnviroLight will be a major step forward in the combined efforts to make Barrow Island as safe as possible for its wildlife while also giving the contractors the cutting-edge lighting technology upon which they've come to rely."
Though Coates Hire West had already converted some of the towers in its catalogue to sodium vapour lamps, Barrow Island's strict EPA quarantine regulations meant only brand new towers were allowed on the island. The EnviroLight towers come with sodium vapour lamps as standard.
In addition to being turtle-friendly, each of the new towers also features a bunded fuel tank, which has a tank within a tank, and Perkins 403D-11 engine - which meets all requirements of the off-highway emissions legislation for EC Stage IIIA/USA EPA Tier 3 and beyond.
