6. In application to 202. 6 (2) of the Rules, "the Guidance" means the requirements specified as follows.

(1) General

(A) In the case of bulk carrier over 5 year of age, the Annual Survey is to include, in addition to the requirements of the Annual Surveys specified in 202. of the Rules, an examination

of the following items:

(B) Extent of Survey

(a) For bulk carriers of 5 - 15 years of age:

(i) An Overall Survey of the foremost cargo hold, including Close-up Survey of suffi- cient extent, minimum 25% of frames, is to be carried out to establish the condition

of:

- Shell frames including their upper and lower end attachments, adjacent shell plat- ing, and transverse bulkheads.

- Suspect areas identified at previous surveys.

(ii) Where considered necessary by the Surveyor as a result of the Overall and Close-up Survey as described in (i) above, the survey is to be extended to include a Close-up

Survey of all of the shell frames and adjacent shell plating of the cargo hold.

(b) For bulk carriers exceeding 15 years of age:

(i) An Overall Survey of the foremost cargo hold, including Close-up Survey is to be

carried out to establish the condition of:

- All shell frames including their upper and lower end attachments, adjacent shell plating, and transverse bulkheads.

- Suspect areas identified at previous surveys.

(a) Thickness measurement is to be carried out to an extent sufficient to determine both

general and local corrosion levels at areas subject to Close-up Survey, as described in

(B) (a) (i) and (b) (i) above. The minimum requirement for thickness measurement for

thickness measurements are suspect areas identified at previous surveys. Where sub- stantial corrosion is found, the extent of thickness measurements should be increased

with the requirements of Annex 1-5, Table 14 of the Guidance.

(b)

The thickness measurement may be dispensed with provided the Surveyor is satisfied by

the Close-up Survey, that there is no structural diminution and the hard protective coat- ing where fitted remains effective.

(D) Special consideration

(a) Where the hard protective coating in the foremost cargo hold is found to be in GOOD condition, the extent of Close-up Surveys and thickness measurements may be specially considered.

Note : For existing bulk carriers, where Owners may elect to coat or recoat cargo holds as noted above, consideration may be given to the extent of the Close-up Surveys and thickness measurement. Prior to the coating of cargo holds of existing ships, scan-

tlings should be ascertained in the presence of a Surveyor.
