The following new part B is inserted after part A:
"Part
B.
GUIDELINES ON THE ENHANCED PROGRAMME OF INSPECTIONS DURING SURVEYS OF BULK
CARRIERS HAVING DOUBLE-SIDE SKIN CONSTRUCTION
1.1 Application*
______________
* The intention
of these Guidelines is to ensure that an appropriate level of review of plans
and documents is conducted and consistency in application is attained. Such
evaluation of survey reports, survey programmes, planning documents, etc.,
should be carried out at the managerial level of the Administration or
organization recognized by the Administration.
1.1.1 The Guidelines should apply to all self-propelled bulk
carriers of 500 gross tonnage and above having double-side skin construction.
Where a bulk carrier has a combination of single- and double-side skin
construction, the relevant requirements of parts A and B should apply to that
construction, as applicable.
1.1.2 The Guidelines should apply to surveys of hull structure
and piping systems in way of cargo holds, cofferdams, pipe tunnels, void spaces
within the cargo length area and all ballast tanks. The surveys should be
carried out during the surveys prescribed by regulation I/10 of the Convention.
1.1.3 The Guidelines contain the extent of examination, thickness
measurements and tank testing. The survey should be extended when substantial
corrosion and/or structural defects are found and include additional close-up
survey when necessary.
1.2 Definitions
1.2.1 Bulk carrier is a ship which is constructed generally with
single deck, topside tanks and hopper side tanks in cargo spaces, and is
intended primarily to carry dry cargo in bulk and includes such types as ore
carriers and combination carriers.**
_________________
** For
combination carriers, additional requirements are specified in the Guidelines
on the enhanced programme of inspections during surveys for oil tankers, set
out in Annex B.
1.2.2 Ballast tank is a tank which is used for water ballast and
includes side ballast tanks, ballast double bottom spaces, topside tanks,
hopper side tanks and peak tanks. A double-side tank should be considered, for
survey purposes, as a separate tank even if it is in connection to either the
topside tank or the hopper side tank.
1.2.3 Spaces are separate compartments including holds and tanks.
1.2.4 Overall survey is a survey intended to report on the
overall condition of the hull structure and determine the extent of additional
close-up surveys.
1.2.5 Close-up survey is a survey where the details of structural
components are within the close visual inspection range of the surveyor, i.e.,
preferably within reach of hand.
1.2.6 Transverse section includes all longitudinal members such
as plating, longitudinals and girders at the deck, sides, bottom, inner bottom,
hopper sides, inner sides, top wing inner sides and longitudinal bulkheads.
1.2.7 Representative spaces are those which are expected to
reflect the condition of other spaces of similar type and service and with
similar corrosion prevention systems. When selecting representative spaces, account
should be taken of the service and repair history on board and identifiable
critical and/or suspect areas.
1.2.8 Suspect areas are locations showing substantial corrosion
and/or are considered by the surveyor to be prone to rapid wastage.
1.2.9 Substantial corrosion is an extent of corrosion such that
assessment of corrosion pattern indicates a wastage in excess of 75% of
allowable margins, but within acceptable limits.
1.2.10 A corrosion prevention system is normally considered a
full hard coating.
Protective coating should usually be epoxy coating or equivalent.
Other coating systems may be considered acceptable as alternatives provided
that they are applied and maintained in compliance with the manufacturer’s
specifications.
Where soft coatings have been applied, safe access should be
provided for the surveyor to verify the effectiveness of the coating and to
carry out an assessment of the conditions of internal structures which may
include spot removal of the coating. When safe access cannot be provided, the
soft coating should be removed.
1.2.11 Coating condition is defined as follows:
GOOD
condition with only minor spot rusting;
FAIR
condition with local breakdown of coating at edges of stiffeners and weld
connections and/or light rusting over 20% or more of areas under consideration,
but less than as defined for POOR condition;
POOR
condition with general breakdown of coating over 20% or more of areas or hard
scale at 10% or more of areas under consideration.
1.2.12 Critical structural areas are locations which have been
identified from calculations to require monitoring or from the service history
of the subject ship or from similar or sister ships to be sensitive to
cracking, buckling or corrosion which would impair the structural integrity of
the ship.
1.2.13 Cargo length area is that part of the ship which includes
all cargo holds and adjacent areas including fuel tanks, cofferdams, ballast
tanks and void spaces.
1.2.14 Intermediate survey is a survey carried out either at the
second or third annual survey or between these surveys.
1.2.15 A prompt and thorough repair is a permanent repair
completed at the time of survey to the satisfaction of the surveyor, therein
removing the need for the imposition of any associated condition of classification
or recommendation.
1.2.16 Convention means the International Convention for the
Safety of Life at Sea, 1974, as amended.
1.2.17 Specially considered means sufficient close-up inspection
and thickness measurements are taken to confirm the actual average condition of
the structure under coating.
1.3 Repairs
1.3.1 Any damage in association with wastage over the allowable
limits (including buckling, grooving, detachment or fracture), or extensive
areas of wastage over the allowable limits, which affects or, in the opinion of
the Administration, will affect the ship’s structural, watertight or
weathertight integrity, should be promptly and thoroughly
repaired. Areas which should be considered include:
.1
side shell frames, their end attachments or adjacent shell plating;
.2
deck structure and deck plating;
.3
bottom structure and bottom plating;
.4
watertight or oiltight bulkheads; and
.5
hatch covers or hatch coamings.
Where adequate repair facilities are not available, the
Administration may allow the ship to proceed directly to a repair facility.
This may require discharging the cargo and/or temporary repairs for the
intended voyage.
1.3.2 Additionally, when a survey results in the identification
of corrosion or structural
defects, either of which, in the opinion of the Administration,
will impair the ship’s
fitness for continued service, remedial measures should be
implemented before the ship
continues in service.
1.4 Surveyors
For bulk carriers of 20,000 tons deadweight and above, two surveyors
should jointly carry out the first scheduled renewal survey after the bulk
carrier passes 10 years of age, and all subsequent renewal surveys and
intermediate surveys. If the surveys are carried out by a recognized
organization, the surveyors should be exclusively employed by such recognized
organizations.
2.1.1 The renewal survey may be commenced at the fourth annual
survey and be progressed during the succeeding year with a view to completion
by the fifth anniversary date.
2.1.2 As part of the preparation for the renewal survey, the
survey programme should be dealt with in advance of the survey. The thickness
measurement should not be held before the fourth annual survey.
2.1.3 The survey should include, in addition to the requirements
of the annual survey, examination, tests and checks of sufficient extent to
ensure that the hull and related piping is in a satisfactory condition and is
fit for its intended purpose for the new period of validity of the Cargo Ship Safety
Construction Certificate, subject to proper maintenance and operation and to
renewal surveys being carried out.
2.1.4 All cargo holds, ballast tanks, including double bottom and
double-side tanks, pipe tunnels, cofferdams and void spaces bounding cargo
holds, decks and outer hull should be examined, and this examination should be
supplemented by thickness measurement and testing, as required by 2.6 and 2.7,
to ensure that the structural integrity remains effective. The examination
should be sufficient to discover substantial corrosion, significant
deformation, fractures, damages or other structural deterioration.
2.1.5 All piping systems within the above spaces should be
examined and operationally tested under working conditions to ensure that the condition
remains satisfactory.
2.1.6 The survey extent of ballast tanks converted to void spaces
should be specially considered in relation to the requirements for ballast
tanks.
2.2.1 A survey in dry dock should be a part of the renewal
survey. There should be a minimum of two inspections of the outside of the
ship’s bottom during the five-year period of the certificate. In all cases, the
maximum interval between bottom inspections should not exceed 36 months.
2.2.2 For ships of 15 years of age and over, inspection of the
outside of the ship’s bottom should be carried out with the ship in dry dock.
For ships of less than 15 years of age, alternate inspections of the ship’s
bottom not conducted in conjunction with the renewal survey may be carried out
with the ship afloat. Inspection of the ship afloat should only be carried out
when the conditions are satisfactory and the proper equipment and suitably
qualified staff are available.
2.2.3 If a survey in dry-dock is not completed in conjunction
with the enhanced survey during renewal survey or if the 36 month maximum
interval referred to in 2.2.1 is not complied with, the Cargo Ship Safety
Construction Certificate should cease to be valid until a survey in dry-dock is
completed.
Where provided, the condition of the corrosion prevention system
of ballast tanks should be examined. For ballast tanks, excluding double bottom
tanks, where a coating is found in POOR condition as defined in 1.2.11, and it
is not renewed, or where a soft coating has been applied, or where a coating
has not been applied, the tanks in question should be examined at annual
intervals. When such breakdown of coating is found in ballast double bottom
tanks, or where a soft coating has been applied or where a coating has not been
applied, the tanks in question may be examined at annual intervals. When
considered necessary by the surveyor, or where extensive corrosion exists,
thickness measurement should be carried out. Where a protective coating is
provided in cargo holds and is found in good condition, the extent of close-up
surveys and thickness measurements may be specially considered.
