(Practice)Standard Practice for Inspecting the Coating System of a Ship
Standard Practice for Inspecting the Coating System of a Ship
SIGNIFICANCE AND USE
This practice establishes the procedure for the inspection of coating systems on board ships. It contains a series of diagrams to be used to report the extent of damage to coatings.
SCOPE
1.1 This practice covers a standard procedure for inspecting the coating system of a ship's topside and superstructure, tanks and voids, decks and deck machinery, and underwater hull and boottop during drydocking. Included are a standard inspection form to be used for reporting the inspection data, a diagram that divides topside and superstructure individual inspection areas, and a series of diagrams that are used to report the extent of damage to the coating system.
1.2 This practice is intended for use only by an experienced marine coating inspector.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

7. Form Instructions
7.1 Inspection Area—The topside/superstructure is divided
into six inspection areas (see Fig. 14). Enter the code for the
area being inspected. (For example, enter “SA” for the super-
structure aft; “SM” for the superstructure midships;“ SF” for
the superstructure forward; “SO” for othersuperstructure, that
is, bulwarks, vents, sideport openings, and so forth; “HS” for
hull starboard; and “HP” for hull port.)
7.1.1 A tank is segmented into seven inspection areas (see
Fig. 15. Enter the code for the area being inspected. (For
example, enter “B” for the bottom of tank inspection, “A” for
the aft bulkhead, and so forth.) A complete list of tank
segments and their codes is shown in Fig. 15.
7.1.2 The underwater hull and boottop are segmented into
twelve distinct inspection areas. Enter the code for the area
being inspected. (For example, enter “P1” for the port bow
inspection, “S1” for the starboard bow inspection, and so
forth.) A complete list of hull segments and their codes is
shown in Fig. 16.
7.1.3 Decks and deck machinery vary so greatly between
ship types that the development of a general diagram with
logical inspection areas and inspection area codes is not
feasible. It should be the responsibility of the organization that
authorizes the inspections to develop the ship diagram, logical
inspection areas, and inspection area codes and to make certain
that this same coding system is used during all subsequent
inspections.
7.2 Date—Enter the date of the inspection. If the inspection
requires more than one day, enter the date the inspection is
completed.
7.3 Ship Name—Enter the ship’s name (for example, LPH-
14, USS Trenton).

corrosion and report each type separately. The six types of
corrosion are as follows:

8.1.3 Pitting Corrosion—Pitting corrosion is a more ad-
vanced form of localized corrosion. Pitting corrosion is char-
acterized by visible indentations or pits that have penetrated
into the steel hull surface. These pits distinguish between
pitting corrosion and general corrosion, the latter being char-
acterized by a layer of rust that does not penetrate locally into
the surface but is more uniform in extent. A photographic
example of pitting corrosion is shown in Fig. 12. FIG. 8 General Corrosion
