Subsea Divers Test New Illuminated Umbilical Technology

September 10, 2009 at 1:21 am Leave a comment

A new energy-efficient LED (light-emitting diode) fiber illumination technology for lighting up to 100 meters of fiber optic cables is to be field tested by subsea divers at The Underwater Centre in Fort William later this month. Developed by PhotoSynergy, a company formed by the University of St. Andrews, the PSL-3000-M is an LED fiber illuminator that will supply a continuous line of light for 100 meters under water. Designed to enhance subsea diver, ROV and tethered operations by offering a permanent light source for subsea navigation, the fiber illuminator cable is visible at depths of up to 150 meters.

            The Underwater Centre in Fort William, the world’s leading commercial diver and ROV training center, will test the lighted umbilical at various depths. An energy efficient alternative to traditional light sources, the PSL-3000-M LED fiber illuminator can use as little as seven watts of power, making it one of the most energy-efficient fiber 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 fiber optic cable. This means it can provide a safe, continuous and flexible light source for subsea divers. The first industry trial will involve the fiber 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 meters, the cable will undergo full trials and depth testing using two of The Underwater Centre’s ROVs – one to perform diver observation of the rescue and the other to monitor the ROV observing the divers.

            Steve Ham, general manager of The Underwater Centre, stated: “Our center offers unique testing conditions that are second to none across the world. We also have some highly experienced divers and ROV pilots on our training team, which is a great backup for any company undertaking trials. We are delighted that PhotoSynergy has chosen The Underwater Centre for testing its LED fiber illuminator – a technology that has the potential to offer the subsea sector a valuable but simple solution to navigational problems, thereby increasing safety and operational efficiency.”

            Small and lightweight, the PSL-3000-M can operate on mains or direct current (DC) with battery back-up or singular battery power, offering flexibility for any given application. The unique optical system designed by PhotoSynergy ensures that optimum light output is channeled down the fiber with maximum power efficiency. The core product produces a green light, the color proven to be nearest the peak eye response for optimal visibility in low light or darkness. Operating mode is switchable between steady illuminations or flashing on/off, the latter of which could be used as an emergency signal in the event of an incident.

            PhotoSynergy Managing Director Don Walker said: “The PSL-3000-M is the output of many years of work on laser-based systems, and we are encouraged by initial discussions with manufacturers and users of umbilicals within the subsea industry. As with any new innovation, it’s important to subject the technology to real life trials, ensuring it meets the challenges that are faced in the offshore environment. We chose The Underwater Centre because of its world-class facilities and the significant support on offer from the experienced subsea team at the Centre, who, we are certain, will be able to make a valuable contribution to the production and further development of this new technology.”
