Explosion Proof Lighting For Cranes
Guidelines for night marking cranes with obstruction lights
Since there is such a variance in Cranes, each case should be assessed individually.
Cranes for oil & gas segments exist in an enormous variety of forms:
— floating cranes, tower cranes and mobile cranes for the sheerlegs segment;
— cranes for offshore applications;
— offshore mast cranes;
— harbor and shipyard cranes for on shore.
There is no single standard defining minimum
mandatory requirements governing design and
installation of obstruction lighting; on the other
hand the most common and widespread
regulations are ICAO's and FAA's.
Most important points to night marking cranes
1 level of low intensity obstruction lights shall be used
45m < H < 105m
2 levels of obstruction lights shall be used: top level with medium intesity, intermediate with low intensity
105m < H < 210m
4 levels shall be used: top with medium intesity, 1st intermediate with low intensity, 2nd intermediate with medium intensity, lower level with low intensityNumber of lights per level
Top level
From 1 to 3 obstruction lights shall be used on the top level: at the top and, if necessary, at jib and counter-jib.
Other levels
1 or 2 obstruction lights shall be used on each level of the tower: the structure has to be indicated from every angle in azimuth.

Most important points to night marking cranes
- lights and their arrangement on the crane shall be such that the structure is indicated from every angle in azimuth;
- the number of lights to be installed at the top and at each level depends on the type of crane;
- the number of light levels depends on the height of the structure;
- lights shall be certified in accordance with ATEX/IECEx beacuse they are installed in hazardous and harsh environments.
