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;
— harbour 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.
