Low Location Light measurements

Low Location Light measurements

At Nordic Sea Safe we have gained a lot of experience over the years in doing Low Location Light measurements on all sorts of ships. We would like to take the opportunity in this article to tell you a bit more about the subject.

Why are Low Location Light measurements needed?

Ships that carry passengers are obligated to have a Low Location Light system for safety purposes. This can be an electric system or a photoluminescent system according to several regulations. A photoluminescent (after glowing) system is 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 saves you money in installation costs, as well as the costs of running the system. Electric low location light systems, however, are connected to the electric network of the ship and will switch on when the regular lights of the ship shut down.

In summary; photoluminescent systems require daylight and/or artificial light to run and do not need electric power. Electrical systems do not require daylight or artificial light but do need a controlling and electrical system to operate.

The regulations for a Low Location Light system also state that the installed system should be checked and measured once every five years. This periodic measurement must meet the DNVGL regulations. In order to make sure that these measurements are done by a neutral, impartial surveyor, ship owners are not allowed to do the measurements themselves. This is where a company like Nordic Sea Safe comes in.

How does Low Location Light measurement work?

The goal of measuring the Low Location Light system is to make sure it still has enough light output to ensure its effectiveness. If not, the system will not meet the expected standards and is insufficient. The minimal light output the system is obligated to meet is expressed in Lumen. Our engineers are DNVGL approved and use high-end equipment that measures the mentioned light output. Logically, measuring an electric LLL system differs from measuring a photoluminescent system. This is due to the fact that electric systems do not require any light to charge up the system. They can be measured instantly. On the other hand, electric systems must be able to run on battery power for at least 60 minutes. To ensure a representative measurement photoluminescent systems need to be charged up properly. This will be taken into account by our specialized engineers.
