ONBOARD LLL TESTING


According to SOLAS 2004 all passenger ships with a capacity to carry more than 36 passengers must have a Low Location Lighting (LLL) system installed identifying the escape routes. The LLL system can be Electrically Powered (EP LLL) or Photoluminescent (PL LLL).

 

SOLAS/III-2/14 “Operational readiness and maintenance” requires a maintenance plan to ensure that the LLL systems installed on board will be effective when most needed – during emergency. In this article we will briefly cover the requirements of PL LLL system maintenance focusing on its critical point – the 5-year luminance measurement test as IMO Resolution A.752(18).

 

A correct action plan for the maintenance of the PL LLL system includes regular and periodical actions. The regular actions are defined as weekly visual checks and replacements if any components of the system are missing or inoperable. All checks and eventual component replacements must be recorded in the PL LLL maintenance log.

To complement the regular maintenance actions, PL LLL luminance tests should be performed at least every 5 years. These readings should be taken on board by a competent entity, using calibrated instrumentation.

 

The competence to perform on board is certified by classification bodies such as DNL/GL, BV, ABS, LR etc….These bodies, also known as a surveyor, are the authority on the performance of the PL LLL luminance tests being the ultimate decision maker on the number of location of the readings needed for each test. Normally, the number of readings per PL LLL luminance test will depend on the number of decks, generally lighting conditions and the density of photoluminescent products in the vessel.

 

The standard procedure for luminance on board measurement service are defined by ISO 15370:2010 – Ships and marine technology – low location lighting (LLL) on passenger ships Arrangement. This standard is of mandatory application because it supplements IMO Resolution A.752

 

Marine Fire Services are accredited as an approved service supplier by LR & BV and therefore deemed a competent entity to perform PL LLL luminance tests on board ships.
