In addition to obstruction lights, the tallest platform of a deepwater port must have a lit rotating beacon that distinguishes the deepwater port from other surrounding offshore structures. The beacon must:

(a)Have an effective intensity of at least 15,000 candela;

(b)Flash at least once every 20 seconds;

(c)Provide a white light signal;

(d)Operate in wind speeds of up to 100 knots at a rotation rate that is within 6 percent of the operating speed displayed on the beacon;

(e)Have one or more leveling indicators permanently attached to the light, each with an accuracy of ±0.25 ° or better; and

(f)Be located:

(1)At least 60 feet (about 18.3 meters) above mean high water;

(2)Where the structure of the platform, or equipment mounted on the platform, does not obstruct the light in any direction; and

(3)So that it is visible all around the horizon.
