PASSING FLOATING PLANT WORKING IN NAVIGABLE CHANNELS

§ 97.30 Passing signals.

(a) Vessels intending to pass dredges or other types of floating plant work

ing in navigable channels, when within a reasonable distance therefrom and not in any case over a mile, shall indiIcate such intention by one long blast of the whistle, and shall be directed to the proper side for passage by the sounding, by the dredge or other floating plant, of the signal prescribed in the local pilot rules for vessels under way and approaching each other from opposite directions, which shall be answered in the usual manner by the approaching vessel. If the channel is not clear, the floating plant shall sound the alarm or danger signal and the approaching vessel shall slow down or stop and await further signal from the plant.

(b) When the pipe line from a dredge crosses the channel in such a way that an approaching vessel cannot pass safely around the pipe line or dredge, there shall be sounded immediately from the dredge the alarm or danger signal and the approaching vessel shall slow down or stop and await further signal from the dredge. The pipe line shall then be opened and the channel cleared as soon as practicable; when the channel is clear for passage the dredge shall so indicate by sounding the usual passing signal as prescribed in paragraph (a) of this section. The approaching vessel shall answer with a corresponding signal and pass promptly.

(c) When any pipe line or swinging dredge shall have given an approaching vessel or tow the signal that the channel is clear, the dredge shall straighten out within the cut for the passage of the vessel or tow.

NOTE: The term "floating plant" as used in §§ 97.30 to 97.36, includes dredges, derrick boats, snag boats, drill boats, pile drivers, maneuver boats, hydraulic graders, survey boats, working barges, and mat sinking plant.

§ 97.31 Speed of vessels passing floating plant working in channels.

Vessels, with or without tows, passing floating plant working in channels, shall reduce their speed sufficiently to insure the safety of both the plant and themselves, and when passing

within 200 feet of the plant their speed shall not exceed five miles per hour. While passing over lines of the plant, propelling machinery shall be stopped.

[CGD 73-100R, 39 FR 11542, Mar. 29, 1974. Redesignated by CGD 81-017, 46 FR 28154, May 26, 1981]

§ 97.32 Light-draft vessels passing floating plant.

Vessels whose draft permits shall keep outside the buoys marking the ends of mooring lines of floating plant working in channels.

§ 97.33 Aids to navigation marking floating plant moorings.

Breast, stern, and bow anchors of floating plant working in navigable channels shall be marked by barrel or other suitable buoys. By night approaching vessels shall be shown the location of adjacent buoys by throwing a suitable beam of light from the plant on the buoys until the approaching vessel has passed, or the buoys may be lighted by red lights, visible in all directions, of the same character as specified in § 97.28(a).

[CGD 73-100R, 39 FR 11543, Mar. 29, 1974. Redesignated by CGD 81-017, 46 FR 28154, May 26, 1981]

§ 97.34 Obstruction of channel by floating plant.

Channels shall not be obstructed unnecessarily by any dredging or other floating plant. While vessels are passing such plant all lines running therefrom across the channel on the passing side which may interfere with or obstruct navigation shall be slacked to the bottom of the channel.

[CGD 73-100R, 39 FR 11543, Mar. 29, 1974. Redesignated by CGD 81-017, 46 FR 28154, May 26, 1981]

§ 97.35 Clearing of channels.

When special or temporary regulations have not been prescribed and action under the regulations contained in §§ 97.30 to 97.34 will not afford clear passage, floating plant in narrow

channels shall, upon notice, move out of the way of vessels a sufficient distance to allow them a clear passage. Vessels desiring passage shall, however, give the master of the floating plant ample notice in advance of the time they expect to pass.

NOTE: If it is necessary to prohibit or limit the anchorage or movement of vessels within certain areas in order to facilitate the work of improvement, application should be made through official channels for establishment by the Secretary of the Army of special or temporary regulations for this purpose.
