not be more than 30 flashes per minute (slow flashing). When it is desired that lights have a distinct cautionary significance, as at sharp turns or sudden constrictions in the channel or to mark wrecks or other artificial or natural obstructions, the frequency of flashes may not be less than 60 flashes per minute (quick flashing). When a light is used on a cardinal system buoy or a vertically striped white and red buoy it shall always be quick flashing. The colors of the lights shall be the same as for reflectors; a red light only on a solid colored red buoy; a green light on solid colored black buoy; white light only for all other buoys including regulatory markers.

§ 66.10-40 Ownership identification.

(a) The use and placement of ownership identification is discretionary, provided that ownership identification is worded and placed in a manner which will avoid detracting from the meaning intended to be conveyed by a navigational aid or regulatory marker.

§ 66.10-45 Mooring (anchor) buoys.

(a) Mooring buoys in State waters for private aids to navigation shall be colored white and shall have a horizontal blue band around the circumference of the buoy centered midway between the top of the buoy and the waterline.

(b) A lighted, mooring buoy shall normally display a slow flashing white light. When its location in a waterway is such that it constitutes an obstruction to a vessel operated during hours of darkness, it shall display a quick flashing white light.

(c) A mooring buoy may bear ownership identification provided that the manner and placement of the identification does not detract from the meaning intended to be conveyed by the color scheme or identification letter when assigned.

Subpart 67.01-General
Requirements

(a) The regulations in this part prescribe the obstruction lights and fog signals to be operated as privately maintained maritime aids to navigation on the artificial islands and structures which are erected on or over the seabed and subsoil of the outer Continental Shelf and in the waters under the jurisdiction of the United States, for the purpose of exploring for, developing, removing and transporting resources therefrom.

(b) Subpart 66.01 in Part 66 of this subchapter shall be applicable to all private aids to navigation erected on or over the outer Continental Shelf in the same manner and to the same extent as they are applicable to private aids to navigation established, erected, or maintained in the waters under the jurisdiction of the United States.

§ 67.01-5 Definitions.

(a) Structures. The term "structures" as used in this part shall include all fixed structures, temporary or permanent, for which a Corps of Engineers' permit is issued. It shall include, but is not necessarily limited to, all drilling platforms, production platforms, quarters platforms, pipe line riser platforms, manifold platforms, loading platforms, boat landings, caissons, well protective structures, tank battery barges submerged on station, drilling barges submerged on location, breakwater barges submerged on location, artificial islands and all other piles, pile clusters, pipes, or structures erected in the waters.

(b) Class "A", "B", or "C" structures. The term "Class A, B, or C structures" refers to the classification assigned to structures erected in areas in which corresponding requirements for marking are prescribed.

(c) Line of demarcation. The term "line of demarcation" means the dividing

line used administratively to distinguish between the areas in which structures shall conform to Class "A" and Class "B" or "C" requirements.

(d) Outer Continental Shelf. The term "Outer Continental Shelf" means all submerged lands lying seaward and outside the area of lands beneath navigable waters as defined in the Submerged Lands Act (sec. 2, 67 Stat. 29, 43 U. S. C. 1301), and of which the subsoil and seabed appertain to the United States and are subject to its jurisdiction and control.

(e) Reliable operation. The term "reliable" as used in this part shall mean that dependability which will insure to the highest degree reasonably possible the uninterrupted operation of lights and fog signals as private aids to navigation for safety of marine commerce.

(f) Fog signal. The term "fog signal" as used in this part shall mean the audible sound signal, authorized as a private aid to navigation, to mark a structure for the safety of marine commerce whenever the visibility has been reduced by fog, mist, rain, falling snow, smoke, dust, or other phenomena.

§ 67.01-10 Authority to regulate and delegation of functions.

(a) Regulatory authority. By virtue of the Department of Transportation Act (Public Law 89-670, 80 Stat. 931-950, 49 U.S.C. 1651-1659), establishing the Department of Transportation, the U.S. Coast Guard together with its functions and duties under the Secretary of the Treasury was transferred to the new department. The Secretary of Transportation thereby became the "head of the Department in which the Coast Guard is operating," including the authority to promulgate and enforce regulations under the Outer Continental Shelf Lands Act (43 U.S.C. 1333). By a rule in 49 CFR 1.9 the Secretary continued in effect actions taken prior to April 1, 1967. By rules in 49 CFR 1.4(a) (2) and (f) the Secretary of Transportation authorized the Commandant, U.S. Coast Guard, with respect to his own organization, to exercise the authority granted to the Secretary as Executive head of that department by any statute, Executive order or regulation. Section 1657 (e) of Title 49 U.S.C. provides for delegation and redelegation of powers and functions vested in

the Secretary. By a rule in 49 CFR 1.4(g) the Commandant is authorized to redelegate and authorize successive redelegations within the organization under his jurisdiction.

[CGFR 68-95, 33 F.R. 15285, Oct. 15, 1968] § 67.01-15

Classification of structures.

(a) The varied depths of water and marine commerce traffic routes which exist in the waters over the Outer Continental Shelf, and in other waters, permits the classification of structures according to their location in such waters. Those structures in the area seaward of the line of demarcation, prescribed by the regulations in this part, are designated as Class "A" structures. All structures shoreward of the line of demarcation, prescribed by the regulations in this part, are designated as either Class "B" or Class "C" structures.

(b) In the event a line of demarcation is not prescribed, the District Commander shall designate a structure “A”, "B", or "C" as he deems appropriate. § 67.01-20 Prescribing lines of demar

67.05-General Requirements for Lights

§ 67.05-1 Arrangement of obstruction lights.

(a) Structures having a maximum horizontal dimension of 30 feet or less on any one side, or in diameter, shall be required to have one obstruction light visible for 360°.

(b) Structures having a maximum horizontal dimension of over 30 feet, but not in excess of 50 feet, on any one side, or in diameter, shall be required to have two obstruction lights installed on diagonally opposite corners, 180° apart, or as prescribed by the District Commander, each light to have a 360° lens.

(c) Structures having a horizontal dimension of over 50 feet on any one side, or in diameter, shall be required to have an obstruction light on each corner, or 90° apart in the case of circular structures, or as prescribed by the District Commander, each light to have a 360° lens.

(d) Where the overall dimensions of a structure require the installation of two or more obstruction lights, the lights shall all be mounted on the same horizontal plane within the limitations of height specified in § 67.20-5, § 67.25-5, or § 67.30-5, as applicable.

(e) Lesser structures and piles, pile clusters or flare templates, etc., will not normally be required to be marked by obstruction lights, when they are located within 100 yards of a Class "A", "B" or "C" structure marked by established obstruction lights, but they shall be marked with red or white retro-reflective material, installed as prescribed by the District Commander.

(f) All obstruction lights shall be installed in a manner which will permit at least one of them to be carried in sight of the mariner, regardless of the angle of approach, until he is within 50 feet of the structure, visibility permitting.

sources as necessary. They shall display a quick-flash characteristic of approximately 60 flashes per minute, unless prescribed otherwise in the permit issued by the District Commander. Their color shall be white when marking Class “A” and "B" structures, and either white or red, as prescribed by the District Commander, when marking Class "C" structures. In determining whether white or red lights shall be authorized, the District Commander shall take into consideration matters concerning, but not necessarily limited to, the dimensions of the structure and the depth of water in which it is located; the proximity of the structure to vessel routes; the nature and amount of vessel traffic; and the effect of background lighting. § 67.05-15

Operating periods of ob

struction lights.

Obstruction lights shall be displayed at all times between the hours of sunset and sunrise, local time, commencing at the time the construction of a structure is begun. During construction and until such time as a platform capable of supporting the obstruction lights is completed, the fixed lights on an attending vessel shall be used. In addition, when lights are in use for general illumination to facilitate the construction or operation of a structure, and can be seen from any angle of approach at a distance equal to that prescribed for the obstruction lights for the class of structure, the actual operation of obstruction lights also will not be required.

[CGFR 58-34, 23 F. R. 7701, Oct. 4, 1958]

§ 67.05-20 Minimum lighting require

ments.

The obstruction lighting requirements prescribed in this part are the minimum requirements only and shall not preclude the maintainer from making application for authorization to establish more lights, or lights of greater intensity than required to be visible at the distances prescribed: Provided, That the prescribed characteristics of color and flash duration are adhered to.

§ 67.05-25 Special lighting require

ments.

Whenever a structure is erected in a position on or adjacent to the edges of navigable channels and fairways, or lines of demarcation, the District Commander is authorized to require the structure to be marked by the lights which in his judgment are necessary for the safety of

ments for Fog Signals

§ 67.10-1 Type and characteristics. (a) The fog signal prescribed in this part shall be the audible sound signal which, in the judgment of the District Commander, is satisfactory in tone, characteristic, and geographic range.

(1) The sound signal produced shall have its maximum intensity at a frequency range above 100 cycles, and shall have a loudness level of 55 phons, at the geographic ranges specified in § 67.20-10, § 67.25-10, or § 67.30–10, as applicable.

(2) The fog signal apparatus when established shall be powered from a reliable power source, and if necessary, an auxiliary power source, to assure that the signal is reliable.

(3) In determining that the fog signal apparatus will provide the loudness level stated in this section, the District Commander may authorize the establishment and operation of the required signal, if it will produce the minimum acceptable sound pressure level in decibels for its fundamental frequency around a 360° horizontal plane passing through the signal, at a distance of 25 feet, measured in an anechoic chamber: Provided, That the minimum value is not less than that shown on the appropriate curve in Table "A" of this part. (For fog signal apparatus which produces an audible signal having appreciable harmonic content, in lieu of considering only the fundamental frequency, all harmonic components 1000 cycles per signal and below may be considered as adding to the loudness level. In evaluating the effect of harmonic components the District Commander will use procedures used within the Coast Guard for such determination.)

(4) In lieu of witnessing the actual test of the fog signal apparatus prior to the issuance of a permit for its establishment and operation the District Commander may accept as proof a certificate prepared by the manufacturer which shows that the particular fog signal apparatus proposed for use is an identical

production model of a type of fog signal which has been tested in the presence of a Coast Guard Officer and which has been found to meet or exceed the requirements of this part.

(b) A fog signal shall be sounded every twenty seconds (sound 2 seconds, silent 18 seconds), unless prescribed otherwise in the permit issued by the District Commander: Provided, That the fog signal characteristic which may be authorized by the District Commander shall be one which is different from the sound signals prescribed in accordance with the "Regulations for Preventing Collisions at Sea, 1960 (33 U.S.C. 1061

1094)," or the local rules established in accordance with Rule 30 thereof, as appropriate.

(c) The fog signal apparatus shall be located on the structure and so arranged that the sound signal produced will be audible over 360° with no wind, to the applicable geographic ranges prescribed in Subpart 67.20, 67.25, or 67.30 of this part: Provided, That the fog signal is located not less than 10 feet, nor more than 100 feet above the water.
