Annex 8 - Survey Reporting
As a principle, for oil tankers subject to ESP, the surveyor
should include the following contents in his report for survey of
hull structure and piping systems, as relevant for the survey.
1.1 A survey report should be generated in the
.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 condition of class (recommendation) has
been imposed or deleted.
1.2 The reporting should 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
.3 survey records, including actions taken, which
should form an auditable documentary trail. Survey reports should
be kept in the survey report file required to be on board;
.4 information for planning of future surveys;
.5 information which may be used as input for
maintenance of classification rules and instructions.
1.3 When a survey is split between different survey
stations, a report should 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, should be made available to the next attending
surveyor, prior to continuing or completing the survey. Thickness
measurement and tank testing carried out should 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.
As a minimum, the identification of location of
close-up survey and thickness measurement should 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 renewal survey and the ship’s age.
Where only partial survey is required, i.e. one web frame
ring/one deck transverse, the identification should include location
within each ballast tank and cargo hold by reference to frame numbers.
2.4 For areas in tanks where 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 should be identified.
2.5 Identification of tanks subject to tank testing.
2.6 Identification of piping systems on deck,
including crude oil washing (COW) piping, and ballast piping within
cargo and ballast tanks, pipe tunnels, cofferdams and void spaces
.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
3 Result of survey
3.1 Type, extent and condition of protective coating
in each tank, as relevant (rated GOOD, FAIR or POOR), including identification
of tanks fitted with anodes.
3.2 Structural condition of each compartment with
information on the following, as relevant:
.1 Identification of findings, such as:
.1.1 corrosion with description of location, type
.1.2 areas with substantial corrosion;
.1.3 cracks/fractures with description of location
.1.4 buckling with description of location and
.1.5 indents with description of location and
.2 Identification of compartments where no structural
damages/defects are found. The report may be supplemented by sketches/photos.
.3 Thickness measurement report should be verified
and signed by the surveyor controlling the measurements on board.
.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 should be included, as relevant:
.4.1 measured and as-built transverse sectional
areas of deck and bottom flanges;
.4.2 diminution of transverse sectional areas
of deck and bottom flanges; and
.4.3 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 should
be identified in a numbered list. Whenever repairs are carried out,
details of the repairs effected should be reported by making specific
reference to relevant items in the numbered list.
4.2 Repairs carried out should be reported with
4.3 For repairs not completed at the time of survey,
condition of class/recommendation should 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, condition
of class/recommendation should be sufficiently detailed with identification
of each item to be repaired. For identification of extensive repairs,
reference may be given to the survey report.
