3 Annual survey
3.1
General
Annual surveys shall be held within three months before or after the
anniversary date from the date of the initial survey or of the date credited for the
last renewal survey. The annual survey shall consist of an examination for the
purpose of ensuring, as far as practicable, that the hull weather decks, hatch
covers, coamings and piping are maintained in a satisfactory condition and shall take
into account the service history, condition and extent of the corrosion prevention
system of ballast tanks and areas identified in the survey report file.
3.2
Examination of the hull
3.2.1 An examination of the hull plating and its closing
appliances shall be carried out as far as can be seen.
3.2.2 An examination of watertight penetrations shall be
carried out as far as practicable.
3.3
Examination of weather decks, hatch covers
and coamings
3.3.1 It shall be confirmed that no unapproved changes
have been made to the hatch covers, hatch coamings and their securing and sealing
devices since the last survey.
3.3.2 A thorough survey of cargo hatch covers and
coamings is only possible by examination in the open as well as closed positions and
shall include verification of proper opening and closing operations. As a result, the
hatch cover sets within the forward 25% of the ship's length and at least one
additional set, such that all sets on the ship are assessed at least once in every
five-year period, shall be surveyed open, closed and in operation to the full extent
in each direction at each annual survey, including:
-
.1 stowage and securing in open condition;
-
.2 proper fit and efficiency of sealing in closed
condition; and
-
.3 operational testing of hydraulic and power
components, wires, chains and link drives.
The closing of the covers shall include the fastening of all peripheral,
and cross joint cleats or other securing devices. Particular attention shall be paid
to the condition of hatch covers in the forward 25% of the ship's length, where sea
loads are normally greatest.
3.3.3 If there are indications of difficulty in
operating and securing hatch covers, additional hatch cover sets above those required
by 3.3.2, at the discretion of the surveyor, shall be tested in operation.
3.3.4 Where the cargo hatch securing system does not
function properly, repairs shall be carried out under the supervision of the
Administration. Where hatch covers or coamings undergo substantial repairs, the
strength of securing devices shall be upgraded to comply with annex 11.
3.3.5 For each cargo hatch cover set, at each annual
survey, the following items shall be surveyed:
-
.1 cover panels, including side plates, and stiffener
attachments that may be accessible in the open position by close-up
survey (for corrosion, cracks, deformation);
-
.2 sealing arrangements of perimeter and cross
joints (gaskets for condition and permanent deformation, flexible
seals on combination carriers, gasket lips, compression bars, drainage
channels and non-return valves);
-
.3 clamping devices, retaining bars, cleating
(for wastage, adjustment, and condition of rubber components);
-
.4 closed cover locating devices (for distortion
and attachment);
-
.5 chain or rope pulleys;
-
.6 guides;
-
.7 guiderails and track wheels;
-
.8 stoppers;
-
.9 wires, chains, tensioners and gypsies;
-
.10 hydraulic system, electrical safety devices
and interlocks; and
-
.11 end and interpanel hinges, pins and stools
where fitted.
3.3.6 At each hatchway, at each annual survey, the
coamings, with plating, stiffeners and brackets shall be checked for corrosion,
cracks and deformation, especially of the coaming tops including close-up survey.
3.3.7 Where considered necessary, the effectiveness of
sealing arrangements shall be confirmed and may be proved by hose or chalk testing
supplemented by dimensional measurements of seal compressing components.
3.3.8 Where portable covers, wooden or steel pontoons
are fitted, the satisfactory condition of the following shall be confirmed, where
applicable:
-
.1 wooden covers and portable beams, carriers or
sockets for the portable beam, and their securing devices;
-
.2 steel pontoons, including close-up survey of
hatch cover plating;
-
.3 tarpaulins;
-
.4 cleats, battens and wedges;
-
.5 hatch securing bars and their securing devices;
-
.6 loading pads/bars and the side plate edge;
-
.7 guide plates and chocks; and
-
.8 compression bars, drainage channels and drain
pipes (if any).
3.3.9 The flame screens on vents to all bunker tanks
shall be examined.
3.3.10 Bunker and vent piping systems, including
ventilators, shall be examined.
3.4
Examination of cargo holds
3.4.1 For double-side skin bulk carriers of 10 to 15
years of age, the following shall be carried out:
-
.1 overall survey of two selected cargo holds;
-
.2 when considered necessary by the surveyor, or
where extensive corrosion exists, thickness measurements shall be carried out.
If the results of these thickness measurements indicate that substantial
corrosion is found, the extent of thickness measurements shall be increased in
accordance with annex 10. These extended thickness measurements shall be
carried out before the survey is credited as complete. Suspect areas identified
at previous surveys shall be examined. Areas of substantial corrosion
identified at previous surveys shall have thickness measurements taken. For
bulk carriers built under the IACS Common Structural Rules, the annual
thickness gauging may be omitted where a protective coating has been applied in
accordance with the coating manufacturer's requirements and is maintained in
GOOD condition; and
-
.3 all piping and penetrations in cargo holds,
including overboard piping, shall be examined.
3.4.2 For double-side skin bulk carriers over 15 years
of age, the following shall be carried out:
-
.1 overall survey of all cargo holds;
-
.2 when considered necessary by the surveyor, or
where extensive corrosion exists, thickness measurements shall be carried out.
If the results of these thickness measurements indicate that substantial
corrosion is found, the extent of thickness measurements shall be increased in
accordance with annex 10. These extended thickness measurements shall be
carried out before the survey is credited as complete. Suspect areas identified
at previous surveys shall be examined. Areas of substantial corrosion
identified at previous surveys shall have thickness measurements taken. For
bulk carriers built under the IACS Common Structural Rules, the annual
thickness gauging may be omitted where a protective coating has been applied in
accordance with the coating manufacturer's requirements and is maintained in
GOOD condition; and
-
.3 all piping and penetrations in cargo holds,
including overboard piping, shall be examined.
3.5
Examination of ballast tanks
Examination of ballast tanks shall be carried out when required as a
consequence of the results of the renewal survey and intermediate survey. When
considered necessary by the Administration, or where extensive corrosion exists,
thickness measurements shall be carried out. If the results of these thickness
measurements indicate that substantial corrosion is found, the extent of thickness
measurements shall be increased in accordance with annex 10.
These extended thickness measurements shall be carried out before the survey is
credited as complete. Suspect areas identified at previous surveys shall be examined.
Areas of substantial corrosion identified at previous surveys shall have thickness
measurements taken. For bulk carriers built under the IACS Common Structural Rules,
the annual thickness gauging may be omitted where a protective coating has been
applied in accordance with the coating manufacturer's requirements and is maintained
in GOOD condition.
3.6
Additional annual survey requirements after determining compliance with regulations
XII/12 and XII/13 of the Convention
3.6.1 For ships complying with the requirements of regulation
XII/12 of the Convention for hold, ballast and dry space water level
detectors, the annual survey shall include an examination and a test, at random, of
the water ingress detection systems and of their alarms.
3.6.2 For ships complying with the requirements of regulation
XII/13 of the Convention for the availability of pumping systems, the
annual survey shall include an examination and a test, of the means for draining and
pumping ballast tanks forward of the collision bulkhead and bilges of dry spaces any
part of which extends forward of the foremost cargo hold, and of their controls.
