PhotoSynergy Ltd (PSL) LIGHTPATH
LIGHTPATH is a patented fibre illumination system a concept that is based on side-emitting optical fibre creating a continuous and flexible line of light only 5mm diameter and typically 75m in length that carries only light and no electrical power.
In developing LIGHTPATH PSL has focused on the generation of a suite of modular products, a family to facilitate operation in challenging subsea environments around deep saturation diving.
The development includes sealed light sources, sealed battery systems, fibre coupling techniques, and non-penetrating switches for operation to 500m depth. The systems include relief valves for operation within saturation bells.
The core Subsea Lighting System products are:
SLS2000 – Identification of diver umbilical route from diver end
SLS5000 – Identification of diver umbilical route from bell
SLS9000 – Multiple diver route identification
The PhotoSynergy LIGHTPATH concept received the Subsea UK Innovation for Safety Award in 2014.
The Innovation for Safety Award recognises an innovation made in a technology that has significantly contributed to improving safety within the subsea sector and was developed with the support of significant organisations operating in the North Sea. These included teams at Bibby Offshore, Boskalis Offshore and Helix Well Ops who supported the trials.
Positive reaction from open days at The Underwater Centre was mirrored by the overwhelmingly positive response from the dive community.
The latest product is the SLS7000 developed for supporting work-class ROVs operating at depths to 3000m to assist and improve ROV utilisation at depth and on the seabed.
PhotoSynergy has recently installed its LIGHTPATH fibre illumination system on the 7MW demonstration offshore wind turbine at Leven. The 2 separate looped systems provide additional lighting on the access steps and around the platform at the base of the t...
Two new products designed to help improve the safety of workers in a range of industries - from subsea to nuclear - have been unveiled by Scottish research and development company PhotoSynergy Ltd (PSL).
