19、GHTING SYSTEM LIGHTING SYSTEM Areas index Calculation (IEC) IEC-61892-2 The number of measuring points required for measuring in a given area is based on the area index and must be based on an even grid layout for the whole area. Area indexNumber of points Below 14 1 and up to 29 2 and up to 316 3 a

20、nd above25 The area index is given by the formula : K= (a*b)/h (a+b) Where K is the area index, a and b are the sides of the room/area and h is the height of the luminaries above the work plane. Any light measurement must be considered in addition to any background light at the place of measurement.

21、 Note: The initial illumination levels should allow for lamp deterioration and accumulation. LIGHTING SYSTEM NORSOK Illumination - For the general level of illuminance at 1 m of elevation, the area requirements according to Annex table apply. - The uniformity of the illminance shall be equal to, or

22、better than, Emin/Emean = 0.5 in process, utility and dril-ling areas. - The uniformity of the illuminance for individual work areas shall be equal to or better than Emin/Emean=0.7. - For lighting calculations, a maintenance factor reflecting the environment and time between maintenance intervals sh

23、all be established and applied. Maintenance factor 0.7 is recomme- nded. - Lighting shall be specified for each workplace that requires at least daily access or is critical from a safety point of view. The guidelines in EN 12464-1 shall be applied in the specification of task lighting. LIGHTING SYST

24、EM - The lighting shall, as a minimum, be included for workplaces that require daily access or detailed reading of information, critical from a safety point of view. This includes gauges, indicators, areas that need to be checked for leakage and areas that frequently need maintenance. - To avoid sha

25、dows, illumination planning shall take the location of fixtures, racks and m echanical equipment into consideration. - The difference in illumination level between adjacent areas should not exceed 5:1. - In enclosed work areas, the difference shall never be more than 40:1 within the total field of v

26、ision. - Provision shall make to avoid direct glare from sunshine, from artificial light sources and from reflecting surfaces. - Glare in visual display units from reflecting surfaces, lamps and windows shall be avoided. - In the design of the lighting, the level of illumination and location of lamp

27、s shall make it easy to see obstructions, steps in corridors, walkways etc. - Different levels of illuminance require different light colors if the lighting is to be comfortable. Warm color should be used in cabin and recreation areas where the lighting levels are below 500lux. High color temperatur

28、e, whiter light, should be used in areas with high light levels. - In areas monitored by closed circuit television, the illuminance shall be sufficient to produce quality video pictures. - The need for adjustable workstation lighting shall be provides as needed for fixed work places. LIGHTING SYSTEM

29、 Emergency Lighting System IEC-61892-2 Emergency lighting shall not be below the escape lighting level requirement as per table Below. The location of the lighting fixture shall be based on the need for light in the emergency operation situation. The emergency lighting system shall be switched on au

30、tomatically in the event of failure of the main source of electrical power. The emergency lighting system shall: ensure illumination for safe operation of emergency systems including manual operation area; illuminate all accommodation spaces, control center, work locations, escape routes; helicopter

31、 deck and other possible evacuation locations such as lifeboat stations; illuminate the sea where lifeboat and life rafts are to be launched; illuminate the identification system of the unit; illuminate all spaces where loss of lighting presents a danger to personal; illumination system for control

32、stations that shall be operative under emergency conditions. Hospitals and emergency hospitals, if any, shall be fully operational at all times. LIGHTING SYSTEM Escape lighting system IEC-61892-2 The escape lighting system shall, as a minimum, provide a lighting level to meet illumination level give

33、n in table below. The escape lighting system shall be switched on automatically in the event of failure of the main and emergency power supply. The location of escape light fixture shall be based on the need for light in the escape situation. The escape lighting systems shall: have a power supply wi

34、th minimum 30 minutes backup time supplied by batteries either integrated or centralized and have a supply from a emergency generator; NOTE the backup should take account of the way in which personal will muster and evacuate a unit, and how much an evacuation is to be taking out; for helicopter and

35、their mobilization time. illuminate all accommodation spaces, control center, work locations, escape routes; helicopter deck and other possible evacuation locations such as lifeboat station; illuminate the sea where lifeboat and life rafts are to be launched; illuminate all spaces where loss of ligh

36、ting presents a danger to personal; illuminate all locations where operation of safety equipment can be necessary to bring the in stallation of a safe stage.
