3. When considered necessary by the
Surveyor, thickness measurement is to be carried out. If the results
of thickness measurement indicate substantial corrosion, the extent of
thickness measurement is to be in accordance with Section 6, Table 3.6.5 Thickness measurement - Single
skin bulk carriers - Shell plating and stiffening, with substantial corrosion, Table 3.6.6 Thickness measurement - Single
skin bulk carriers - Double bottom and hopper structure, with substantial
corrosion, Table 3.6.7 Thickness measurement - Single and
double skin bulk carriers - Transverse bulkheads in cargo holds, with substantial
corrosion, Table 3.6.8 Thickness measurement - Single
skin and double skin bulk carriers - Deck structure* with substantial corrosion , Table 3.6.9 Thickness measurement - Double
skin bulk carriers - Double side space structure (including wing void spaces of ore
carriers), with substantial corrosion and Table 3.6.10 Thickness measurement - Double
skin bulk carriers - Double side space structure (including wing void spaces of ore
carriers), with substantial corrosion as applicable. The survey will not
be considered complete until these additional thickness measurements
have been carried out.

Note
4. Where protective coatings are found
in GOOD condition, as defined in Pt 1, Ch 3, 1.5 Definitions, the extent of the Close-up Survey may be
specially considered. When considered necessary by the Surveyor,
thickness measurement is to be carried out. However, prior to any
coating or recoating of cargo holds, scantlings are to be confirmed by
thickness measurement with the Surveyor in attendance.

2.2.39 For general dry cargo ships, in addition to the applicable
requirements of Pt 1, Ch 3, 2.2 Annual Surveys 2.2.1, the following are required for ships over
15 years of age:
-
Overall survey of all cargo holds and 'tween deck spaces.
-
Close-up Survey of at least 25 per cent of shell frames, including
their end attachments and adjacent shell plating in a forward lower cargo hold and
one other selected lower cargo hold. Close-up Survey is to include the lower one
third length of the shell frames.
-
Where the survey reveals the need for remedial measures, then the
survey is to be extended to include the Close-up Survey of all shell frames and
adjacent shell plating in those cargo holds and associated tween deck spaces, as
well as a Close-up Survey of sufficient extent of all remaining cargo holds and
tween deck spaces.
-
Where the protective coatings in cargo holds are found in GOOD
condition, as defined in Pt 1, Ch 3, 1.5 Definitions, the extent of Close-up Survey may be specially
considered.
-
When considered necessary by the Surveyor, thickness measurement is
to be carried out. If the results of thickness measurement indicate substantial
corrosion, the extent of thickness measurement is to be in accordance with Table 3.5.6 Thickness measurement - Additional
requirements in way of structure identified with substantial corrosion in Pt 1, Ch 3, 5 Special Survey - General - Hull requirements. The survey will not be considered complete until
these additional thickness measurements have been carried out. Steel renewal
requirements have been separately determined according to date of contract for
construction for cargo hold hatch covers and coamings under IACS UR S21A. Where
the gauged thickness is within the range t
net + 0,5 mm and t
net + 1,0 mm, a coating (applied in accordance with coating
manufacturer’s requirements) or annual gauging may be adopted as an alternative to
steel renewal. See
Pt 1, Ch 3, 5.6 Thickness measurement 5.6.7.
2.2.41 For roll on-roll off ships (i.e. those that utilise a loading ramp
which enables wheeled vehicles to be rolled on and rolled off the ship), in addition to
the requirements of Pt 1, Ch 3, 2.2 Annual Surveys 2.2.1, the requirements of Pt 1, Ch 3, 22 Bow, inner, side shell and stern doors on Ro-Ro ships are to be complied with, as applicable. For ships other
than roll on-roll off ships, fitted with bow doors, inner doors, side doors and stern
doors, in addition to the requirements of Pt 1, Ch 3, 2.2 Annual Surveys 2.2.1, the following are to be satisfactorily dealt with,
as applicable:
-
Verification of the freedom of movement of doors, and operation of
their power units.
-
Examination of the door structure and surrounding ship structure.
-
Examination of the door sealing arrangements including gaskets and
retaining bars.
-
Examination of the door cleating, locking and securing
arrangements.
-
Examination of the door hinging arrangements.
-
Verification of the local and/or remote control of the securing
devices/cleats.
-
Examination of all equipment associated with the opening, closing and
securing of the door, e.g. wire ropes, chains, sheaves, rollers, guides, shackles,
etc.
-
Verification of the tightness of the doors.
-
Examination and testing of remote control panels and associated
indicator lights, closed circuit television systems, water leakage indicator
lights and alarm systems.
-
Examination of the required notice boards and verification of log
entries.
-
Verification of the satisfactory testing of the bilge systems for the
space between the inner and outer bow doors and of the vehicle deck.
-
Verification that the approved Operation and Maintenance Manual is on
board and satisfactorily maintained.
2.2.42 For navigational arrangements for periodic one man watch and
integrated bridge systems, Annual Surveys are to be carried out in accordance
with the approved test schedule as required by Pt 7, Ch 9, 1.2 Information and plans required to be submitted 1.2.1 to ascertain that the equipment and
arrangements required for the applicable class notation(s) are being maintained in good
working order. At the time of the survey, relevant statutory certificates may be
accepted as evidence of satisfactory operation.
2.2.44 The Surveyor is to examine the fixed cargo securing fittings as far as
necessary and practicable in order to be satisfied as to their general condition,
see
