Bulk carrier is a ship which
is constructed generally with single deck, top-side 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
Ballast tank is a tank which
is used for water ballast and includes side ballast tanks, ballast
double bottom spaces, top-side tanks, hopper side tanks and peak tanks.
Spaces are separate compartments
including holds and tanks.
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.
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
Transverse section includes
all longitudinal members such as plating, longitudinals and girders
at the deck, side and bottom, inner bottom and hopper side plating,
longitudinal bulkheads, and bottom plating in top wing tanks.
Representative spaces are those
which are expressed 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 onboard and identifiable critical and/or suspect
Suspect areas are locations
showing substantial corrosion and/or are considered by the surveyor
to be prone to rapid wastage.
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
1.2.10 A corrosion prevention system is normally
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.
Coating condition is defined
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
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.
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.
Intermediate survey is a survey
carried out either at or between 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.
Specially considered means
sufficient close-up inspection and thickness measurements are taken
to confirm the actual average condition of the structure under coating.
