                TITLE 33--NAVIGATION AND NAVIGABLE WATERS
 
   CHAPTER I--COAST GUARD, DEPARTMENT OF HOMELAND SECURITY (CONTINUED)
 
PART 164--NAVIGATION SAFETY REGULATIONS--Table of Contents
 
Sec. 164.13  Navigation underway: tankers.

    (a) As used in this section, ``tanker'' means a self-propelled tank 
vessel, including integrated tug barge combinations, constructed or 
adapted primarily to carry oil or hazardous material in bulk in the 
cargo spaces and inspected and certificated as a tanker.
    (b) Each tanker must have an engineering watch capable of monitoring 
the propulsion system, communicating with the bridge, and implementing 
manual control measures immediately when necessary. The watch must be 
physically present in the machinery spaces or in the main control space 
and must consist of at least a licensed engineer.
    (c) Each tanker must navigate with at least two licensed deck 
officers on watch on the bridge, one of whom may be a pilot. In waters 
where a pilot is required, the second officer, must be an individual 
licensed and assigned to the vessel as master, mate, or officer in 
charge of a navigational watch, who is separate and distinct from the 
pilot.
    (d) Except as specified in paragraph (e) of this section, a tanker 
may operate with an auto pilot engaged only if all of the following 
conditions exist:
    (1) The operation and performance of the automatic pilot conforms 
with the standards recommended by the International Maritime 
Organization in IMO Resolution A.342(IX).
    (2) A qualified helmsman is present at the helm and prepared at all 
times to assume manual control.
    (3) The tanker is not operating in any of the following areas:
    (i) The areas of the traffic separation schemes specified in 
subchapter P of this chapter.
    (ii) The portions of a shipping safety fairway specified in part 166 
of this chapter.
    (iii) An anchorage ground specified in part 110 of this chapter.
    (iv) An area within one-half nautical mile of any U.S. shore.
    (e) A tanker equipped with an integrated navigation system, and 
complying with paragraph (d)(2) of this section, may use the system with 
the auto pilot engaged while in the areas described in paragraphs (d)(3) 
(i) and (ii) of this section. The master shall provide, upon request, 
documentation showing that the integrated navigation system--
    (1) Can maintain a predetermined trackline with a cross track error 
of less than 10 meters 95 percent of the time;
    (2) Provides continuous position data accurate to within 20 meters 
95 percent of the time; and
    (3) Has an immediate override control.
