Besides our turn-key solutions, T-ISS offers service for the installation of signs, Low Location Light systems and pipe marking by our highly skilled and experienced engineers.
Examples of our installation services:
● IMO Safety Sign survey and installation
● Low Location Light survey and installation
● Pipe Marking survey and installation
● Spray Stop Anti-Splash tape survey and installation
● Complete sign refurbishment projects
T-ISS is accredited by DNV to execute Low Location Light measurement services, our certification can be found under Downloads.
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
According to several regulations, vessels that carry passengers are obligated to have a Low Location Light system installed. This could be a photo luminescent system as well as an electric system. A photo luminescent 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 will save you money in installation costs, as well as the costs of running the system.
On the other side we have the electric low location light systems. These systems are connected to the electric network of the ship, and will switch on when the regular lighting of the ship shuts off. 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 to run, but require a controlling and electrical system to operate.
The regulations that oblige having an Low Location Light system also state that the installed Low Location Light 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, vessel owners are not allowed to do the measurements themselves. This is where a company like T-ISS comes in.
Essentially, the goal of the Low Location Light measurement is making sure the system still has enough light output to ensure its effectiveness. If not, the system’s performance is insufficient and won’t meet the expected standards set by the regulations. 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 photo luminescent system. This due to the fact that electric systems don’t require any light to charge up the system, and 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, photo luminescent systems need to be charged up properly, which will be taken into account by our specialized engineers.
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.
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.
