§ 88.15 Lights on dredge pipelines.

Dredge pipelines that are floating or supported on trestles shall display the following lights at night and in periods of restricted visibility. (a) One row of yellow lights. The lights must be

(1) Flashing 50 to 70 times per minute,
(2) Visible all around the horizon,
(3) Visible for at least 2 miles on a clear dark night,

(4) Not less than 1 and not more than 3.5 meters above the water,

(5) Approximately equally spaced, and

(6) Not more than 10 meters apart where the pipeline crosses a navigable channel. Where the pipeline does not cross a navigable channel the lights must be sufficient in number to clearly show the pipeline's length and course.

(b) Two red lights at each end of the pipeline, including the ends in a channel where the pipeline is separated to allow vessels to pass (whether open or closed). The lights must be

(1) Visible all around the horizon, and
(2) Visible for at least 2 miles on a clear dark night, and

(3) One meter apart in a vertical line with the lower light at the same height above the water as the flashing yellow light.

INTERPRETATIVE RULES

Sec.
82.1 Purpose.
82.3 Pushing vessel and vessel being pushed: Composite unit.

AUTHORITY: 33 U.S.C. 180, 30 Stat. 98; 49 CFR 1.46(c)(2); 28 Stat. 647, 33 U.S.C. 258; 49 CFR 1.46(c)(3); sec. 4233 R.S., 33 U.S.C. 322.

§ 82.1 Purpose.

(a) This part contains the interpretative rules concerning the 72 COLREGS that are adopted by the Coast Guard for the guidance of the public.

§ 82.3 Pushing vessel and vessel being pushed: Composite unit.

Rule 24(b) of the 72 COLREGS states that when a pushing vessel and a vessel being pushed ahead are rigidly connected in a composite unit, they are regarded as a power-driven vessel and must exhibit the lights under Rule 23. A "composite unit” is interpreted to be a pushing vessel that is rigidly connected by mechanical means to a vessel being pushed so they react to sea and swell as one vessel. “Mechanical means" does not include the following:

(a) Lines.
(b) Hawsers.
(c) Wires.

(d) Chains. (CGD 76-133, 42 FR 35792, July 11, 1977. Redesignated by CGD 81-017, 46 FR 28154, May 26, 1981)
