LOW LOCATION LIGHT (LLL) MEASUREMENTS

$0.00

T-ISS is accredited by DNV to execute Low Location Light measurement services.

As a vessel owner, you need to test all Low Location Light systems at least once every five years. T-ISS engineers will test the luminance of your LLL systems on-board with fully certified test equipment. The measurement process as well as equipment are all certified by DNV. We will report all readings including the required upgrades and/or modifications. We will do this upon completion of the measurement survey, and when all systems meet the legally required ratings.

Examples of our LLL measuring services:

  • Photo luminescent Low Location Light measurements and tests (DNVGL certified)
  • Electric Low Location Light measurements and tests (DNVGL certified)
  • Low Location Light refurbishment or replacement

LOW LOCATION LIGHT MEASUREMENTS BY T-ISS

When you consider T-ISS as the right partner for the required measurements on your vessel, feel free to contact us. This way we can advise you and answer any questions you may still have according to LLL measurements. One of our engineers can analyze your specific situation and vessel. This way, he will advise you with substantiated information. After the measurements, the engineer that executed the measurement will report all readings in a clear overview. This will include all the upgrades and / or modifications that, when needed, must be done to meet the required regulations.

WHAT IF THE RESULTS OF THE LLL MEASUREMENTS ARE NEGATIVE?

In some cases it may occur that the measured and tested Low Location Light system isn’t meeting the required specifications. In this case, the inadequate Low Location Light needs to be replaced and renewed. This way the system will meet its regulations again.

T-ISS is a specialist when it comes down to the installation and renewal of LLL systems on cruise liners, ferries and all other vessels that carry passengers.

Description

More Information

According to the regulations, vessels that carry more than 12 passengers must have a Low Location Light system
installed. The photoluminescent LLL system will be charged by the lighting on the vessel and will use the energy
it collects to light up in the dark.

The big advantage of this system is that there are no electric installations that need to be installed. This will save
you money in installation costs, as well as the costs of running the system.

Rules and regulations details system requirements, of which below we highlight:
● The installed material must be Class/Wheelmark approved.
● All escape routes, including stairs, must be marked by LLL.
● Where stairs or corridors are more than 2m wide, LLL ships should be provided on both sides.
● ‘Exit’ signs should be provided at each exit, located on the same side as the door handle.
● Fire and watertight doors should be marked to show how the door opens.
● LLL lightning must be placed not more than 30cm above the deck at all points of the escape route.
● Systems must have their luminescence tested at least once every 5 years.
