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
carriersfootnote
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.
