Annex 8 – Survey Reporting
Principles
As a principle, for oil tankers subject to this Code, the surveyor(s) shall
include the following contents in the report for survey of hull structure and piping
systems, as relevant for the survey. The structure of the report content may be
different, depending on the reporting system of the Administration.
1 General
1.1 A survey report shall be generated in the following
cases:
-
.1 in connection with commencement, continuation
and/or completion of periodical hull surveys, i.e. annual, intermediate
and renewal surveys, as relevant;
-
.2 when structural damages/defects have been found;
-
.3 when repairs, renewals or modifications have
been carried out; and
-
.4 when a condition of class (recommendation) has
been imposed or has been deleted.
1.2 The reporting shall provide:
-
.1 evidence that prescribed surveys have been
carried out in accordance with applicable requirements;
-
.2 documentation of surveys carried out with
findings, repairs carried out and condition of class (recommendation) imposed
or deleted;
-
.3 survey records, including actions taken, which
shall form an auditable documentary trail. Survey reports shall be kept in the
survey report file required to be on board;
-
.4 information for planning of future surveys;
and
-
.5 information which may be used as input for
maintenance of classification requirements and instructions.
1.3 When a survey is split between different survey
stations, a report shall be made for each portion of the survey. A list of items
surveyed, relevant findings and an indication of whether the item has been credited,
shall be made available to the next attending surveyor, prior to continuing or
completing the survey. Thickness measurement and tank testing carried out shall also
be listed for the next surveyor.
2 Extent of the survey
2.1 Identification of compartments where an overall
survey has been carried out.
2.2 Identification of locations, in each tank,
where a close-up survey has been carried out, together with information
of the means of access used.
2.3 Identification of locations, in each tank, where
thickness measurement has been carried out.
- Note: As a minimum, the identification of location of close-up
survey and thickness measurement shall include a confirmation with description of
individual structural members corresponding to the extent of requirements
stipulated in this part of annex B based on type of periodical survey and the
ship's age.
Where only a partial survey is required, i.e. one web frame ring/one deck transverse,
the identification shall include the location within each ballast tank and cargo tank
by reference to frame numbers.
2.4 For areas in tanks where the protective coating is
found to be in GOOD condition and the extent of close-up survey and/or thickness
measurement has been specially considered, structures subject to special
consideration shall be identified.
2.5 Identification of tanks subject to tank testing.
2.6 Identification of cargo piping systems on deck,
including crude oil washing (COW) piping, and ballast piping within cargo and ballast
tanks, pump-rooms, pipe tunnels, cofferdams and void spaces where:
-
.1 examination, including internal examination of
piping with valves and fittings and thickness measurement, as relevant, has
been carried out; and
-
.2 operational test to working pressure has been
carried out.
3 Result of survey
3.1 Type, extent and condition of protective coating in
each tank, as relevant (rated GOOD, FAIR or POOR.
3.2 Structural condition of each compartment with
information on the following, as relevant:
-
.1 Identification of findings, such as:
-
.1 corrosion with description of location, type
and extent;
-
.2 areas with substantial corrosion;
-
.3 cracks/fractures with description of location
and extent;
-
.4 buckling with description of location and extent;
and
-
.5 indents with description of location and extent.
-
.2 Identification of compartments where no
structural damages/defects are found. The report may be supplemented by
sketches/photographs;
-
.3 Thickness measurement report shall be verified
and signed by the surveyor witnessing the measurements on board; and
-
.4 Evaluation result of longitudinal strength of
the hull girder of oil tankers of 130 m in length and upwards and over 10 years
of age. The following data shall be included, as relevant:
-
.1 measured and as-built transverse
sectional areas of deck and bottom flanges;
-
.2 diminution of transverse sectional areas
of deck and bottom flanges; and
-
.3 details of renewals or reinforcements
carried out, as relevant (see 4.2).
4 Actions taken with respect to findings
4.1 Whenever the attending surveyor is of the opinion
that repairs are required, each item to be repaired shall be identified in a survey
report. Whenever repairs are carried out, details of the repairs effected shall be
reported by making specific reference to relevant items in the survey report.
4.2 Repairs carried out shall be reported with
identification of:
4.3 For repairs not completed at the time of survey, a
condition of class/recommendation shall be imposed with a specific time limit for the
repairs. In order to provide correct and proper information to the surveyor attending
for survey of the repairs, the condition of class/recommendation shall be
sufficiently detailed with identification of each item to be repaired. For
identification of extensive repairs, reference may be given to the survey report.
