Analysis of offshore platform lighting system

Offshore platform is the basic facility for offshore oil and gas resources development, and is the base of marine production and operation. Due to the narrow space of the offshore platform, the space of the production equipment is very compact, and the production and operation personnel should be concentrated.

The analysis of the illumination light source of the offshore platform should take into account the characteristics of the light source, such as the light efficiency, color rendering, life, start and restart time, and the surrounding environment. In recent years, the gas discharge light source (sodium lamp, fluorescent lamp, metal halide lamp etc.) because of its high efficiency, low power consumption, long service life, corrosion and other advantages, has replaced the traditional incandescent lighting light source, has been widely used in place of city roads, highways, airports, squares, industrial lighting etc..

Offshore platform is the basic facility for offshore oil and gas resources development, and is the base of marine production and operation. Due to the narrow space of the offshore platform, the space of the production equipment is very compact, and the production and operation personnel should be concentrated.

1) safety of offshore platform in the exploitation of oil and gas and oil and gas treatment process, will produce a large number of flammable and explosive gas, especially in the case of personnel and equipment on the premises, how to prevent the occurrence of explosion accident lighting has become a very important topic. Because the lighting at startup or work, will produce the spark or the formation of hot surface, once encountered explosive gas, will cause an explosion, directly endanger the whole platform of production and production and operation personnel safety. Therefore, in the choice of lighting must meet the explosion-proof requirements;

2 efficient, as far as possible to choose a high light efficiency, long life, low energy consumption of light source. In order to ensure the safety of offshore platform oil and gas production, the platform deck lighting equipment is widely used in explosion-proof high-pressure sodium lamp and fluorescent lamp. The lighting mode adopts the general illumination and the mixed illumination way, in order to meet the operating requirements of the specific region, the local lighting is adopted to improve the illumination of the working area, so as to meet the visual needs of the construction workers.

However, as a gas discharge light source, high pressure sodium lamp and fluorescent lamp also exist some deficiencies:

1) light utilization efficiency is low, the light emitted from the light must pass through a reflection lamp or two reflection, effective energy utilization rate of only 40% to 60%, while the remaining energy is converted into heat and consumed in vain, the surface of the lamp with high temperature;

2, due to the harsh environment of the offshore platform, the sea wind and the equipment on the platform in the process of vibration. The filament is very low in the hot working environment, and the vibration can greatly shorten the service life of the lamp bulb, and cause the filament breakage and the bulb to be loosened;

3 high pressure sodium lamp contains a large number of infrared and ultraviolet radiation, color rendering index is low (Ra=20 ~ 30), color temperature is generally 1900K ~ 2000K;

4) lamps contain a large number of harmful elements such as mercury, sodium, and can not be recovered after damage, causing pollution to the environment.
