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

Subsea & Marine LIGHTPATH

Subsea air-dive umbilicals
The LIGHTPATH fibre can simply be wound into the lay of an existing umbilical to allow the retro-fit of the illumination system. Installation will typically be an hour for a 65m umbilical. When coupled to either the SLS5000 or SLS9000, the fibre presents a continuous line of light indicating the route of the umbilical. This can be from both Saturation and Wet bells.

The increased visibility is beneficial to both the individual diver, his colleagues in the water, the Bell man and the supporting ROV pilots, who can monitor for potential umbilical snagging risks. The individual diver can be identified by the use of different illumination colours.

Marine
The LIGHTPATH can be used for numerous lighting applications in confined spaces, hand-rails, open hatches, stairs and gangways and can be deployed rapidly from a portable drum. A number of lighting options are available depending on the application and location. These include 24V DC with emergency battery back-up or stand-alone battery operation.

Both the above applications have the option to be operated in flash mode.
