For requirements see these sections in Part 151:.10-1.13- 5.15- 1.15-5.15- 10.20- 1.20- 5.25-1.25-2.30  111.105 (Sub-chapter J).40.04- 5

See Table 2 of Part 153 for additional cargoes permitted to be carried by tankbarge.

Terms and symbols:

Segregation—Tank—

   Line 1—Segregation of cargo from surrounding waters:

      i = Skin of vessel (single skin) only required. Cargo tank wall can be vessel's hull.

       i i = Double skin required. Cargo tank wall cannot be vessel's hull.

   Line 2—Segregation of cargo space from machinery spaces and other spaces which have or could have a source of ignition:

      i = Single bulkhead only required. Tank wall can be sole separating medium.

       i i = Double bulkhead required. Cofferdam, empty tank, pumproom, tank with Grade E Liquid (if compatible with cargo) is satisfactory.

Internal tank inspection—

   G—Indicates cargo is subject to general provisions of 151.04-5(b).

   Specific numbers in this column are changes from the general provisions.

Abbreviations used:

Tank type: Ind = Independent.

Vent:

   PV = Pressure vacuum valve.

   SR = Safety relief.

Gauging device: Restr. = Restricted.

General usage:

   NR = No requirement.

   NA = Not applicable.

1. The provisions contained in 46 CFR Part 197, subpart C, apply to liquid cargoes containing 0.5% or more benzene by volume.
