(A) One transverse web with associated plating and longitudinals in two representative water ballast tanks of each type. This shall include the foremost topside and double-side water ballast tanks on either side. (C) Two selected cargo hold transverse bulkheads, including internal structure of upper and lower stools, where fitted. (D) All cargo hold hatch covers and coaming (plating and stiffeners).	(A) One transverse web with associated plating and longitudinals as applicable in each water ballast tank. (A) Forward and aft transverse bulkheads including stiffening system in a transverse section including topside, hopper side and double-side ballast tanks on one side of the ship (i.e. port or starboard). (B) 25% of ordinary transverse frames for transverse framing systems or 25% of longitudinals for longitudinal framing systems on side shell and inner side plating at forward, middle and aft parts in the foremost double-side tanks. (C) One transverse bulkhead in each cargo hold, including internal structure of upper and lower stools, where fitted. (D) All cargo hold hatch covers and coamings (plating and stiffeners). (E) All deck plating and under-deck structure inside line of hatch openings between all cargo hold hatches.	(A) All transverse webs with associated plating and longitudinals as applicable in each water ballast tank. (A) All transverse bulkheads including stiffening system in each water ballast tank. (B) 25% of ordinary transverse frames for transverse framing systems or 25% of longitudinals for longitudinal framing systems on side shell and inner side plating at forward, middle and aft parts in all double-side tanks. (C) All cargo hold transverse bulkheads including internal structure of upper and lower stools, where fitted. (D) All cargo hold hatch covers and coamings (plating and stiffeners). (E) All deck plating and under-deck structure inside line of hatch openings between all cargo hold hatches.	(A) All transverse webs with associated plating and longitudinals as applicable in each water ballast tank. (A) All transverse bulkheads including stiffening system in each water ballast tank. (B) All ordinary transverse frames for transverse framing systems or all longitudinals for longitudinal framing systems on side shell and inner side plating at forward, middle and aft parts in all double-side tanks. Areas (C)–(E) as for renewal survey No.3

(A), (B), (C), (D) and (E) are areas which shall be subjected to close-up surveys and thickness measurements (see sketches in appendix 3 to annex 8A/annex 8B).
(A) Transverse web frame or watertight transverse bulkhead in topside, hopper side and double-side ballast tanks. In fore and aft peak tanks transverse web frame means a complete transverse web frame ring including adjacent structural members.
(B) Ordinary transverse frame in double-side tanks.
(C) Cargo hold transverse bulkhead, plating, stiffeners and girders.
(D) Cargo hold hatch covers and coamings. For cargo hold hatch covers of approved design which structurally have no access to the internals, close-up survey/thickness measurement shall be done of accessible parts of hatch covers' structures.
(E) Deck plating and under-deck structure inside line of hatch openings between cargo hold hatches.

*Note:* Close-up survey of transverse bulkheads shall be carried out at four levels: Level (a) Immediately above the inner bottom and immediately above the line of gussets (if fitted) and shedders for ships without lower stool. Level (b) Immediately above and below the lower stool shelf plate (for those ships fitted with lower stools), and immediately above the line of the shedder plates. Level (c) About mid-height of the bulkhead. Level (d) Immediately below the upper deck plating and immediately adjacent to the upper wing tank, and immediately below the upper stool shelf plate for those ships fitted with upper stools, or immediately below the topside tanks.
