A new energy-efficient LED (light-emitting diode) fibre illumination technology for lighting up to 100 metres of fibre optic cables is to be trialled by subsea divers at The Underwater Centre in Fort William, UK.
Developed by PhotoSynergy, a limited company formed by the University of St Andrews, the PSL-3000-M is an LED fibre illuminator that will supply a continuous line of light for 100 metres at subsea level.
Designed to enhance subsea diver, ROV and tethered operations by offering a permanent light source for subsea navigation, the fibre illuminator cable is visible at depths of up to 150 metres.
The technology is being trialled by divers at The Underwater Centre in Fort William and will be tested at various depths. An energy efficient alternative to traditional light sources, the PSL-3000-M LED fibre illuminator can use as little as seven watts of power, making it one of the most energy efficient fibre illuminators on the market.
With the control box remaining on the surface or housed in a diving bell or ROV, there is no actual power in the side-emitting fibre optic cable. This means it can provide a safe, continuous and flexible light source for subsea divers.
This first industry trial of the technology at The Underwater Centre will involve the fibre optic cable being attached to two diver umbilicals as they perform a diver rescue. Operating close to the Centre’s private pier, at depths starting at 20 metres, the cable will undergo full trials and depth testing.
