1.1.2 A survey checklist
(Form 2113(N)) has been prepared in accordance with the Regulations
and should be used for all surveys, see
Ch 24 Appendix 5 Form 2113(N).
1.1.3 Salt-water
ballast tanks should be internally examined, and if extensive corrosion
is found, gauged as necessary. Any tanks which must be examined annually
will be indicated in the Memoranda.
1.1.4
Vol 1, Pt 1, Ch 3, 2 Annual Surveys – Hull, machinery and optional requirements of the Rules for
Naval Ships, states that the Surveyor is to examine the ship at Annual
Surveys “so far as is necessary and practicable”, in order
to be satisfied as to its general condition. The intention is that
Surveyors should be satisfied that the vessel remains ‘in Class’.
If any parts of the structure are found to be materially reduced or
otherwise defective, special attention should also be paid to corresponding
areas of the structure in other spaces and any defects are to be made
good or other satisfactory arrangements made.
1.1.5 In the case
of an incomplete survey, the outstanding items are to be noted on
the Interim Certificate and the new date of survey is to be recommended
for assignment upon completion. Items should be reported as outstanding
when they have been examined and found to require remedial action
which cannot be dealt with at the time of survey. A suitably worded
Condition of Class should also be considered.
1.1.6 Where the survey
is being carried out concurrently with a Continuous Special Survey
cycle, it will be necessary to complete those requirements of the
Annual Survey which have not been covered by the Continuous Survey.
1.1.7 Upon satisfactory
completion of the Annual Survey, the Certificate of Class is to be
endorsed.
1.1.8
Vol 1, Pt 1, Ch 3, 2.1 General 2.1.2 and Vol 1, Pt 3, Ch 4, 4 Watertight doors and hatches in watertight subdivision boundaries of the Rules for
Naval Ships indicate the requirements for bow, inner, side and stern
doors and ramps. At Annual Surveys the doors and associated equipment
should be examined to confirm a satisfactory condition and the survey
checklist should be used when carrying out the Survey. Particular
attention should be paid to the structure in way of the door, sealing
arrangements, hinging, cleating and securing arrangements for any
signs of cracks, corrosion and deformation. A function test should
be carried out on these doors and ramps.
1.1.9
Vol 1, Pt 1, Ch 3, 2.2 Hull 2.2.3 of the Rules
for Naval Ships includes a requirement that the anchoring and mooring
equipment and arrangements be examined as far as is practicable. Surveyors
are to examine the anchors, chain cables and capstan/windlass as far
as is practicable in order to confirm the equipment is in satisfactory
condition. For those ships where mooring ropes are required in accordance
with the Rules for Naval Ships, then the Surveyors should also examine
the mooring ropes to confirm that they are in a satisfactory condition.
One anchor should be lowered and raised as far as practicable.
1.1.10 In order
to verify the watertight integrity of the hull both externally and
internally, the C11(N) should be verified against actual arrangements.
Where a significant proportion of the arrangements on the C11 are
found in a satisfactory condition, the extent of survey of the remaining
items will be to the Surveyor’s satisfaction. Items not covered
by a survey are to be listed in the report.
1.1.11 In general,
external boundary and internal bulkheads or decks are required to
be watertight up to the vertical limit of watertight integrity, see
Vol 1, Pt 3, Ch 2, 1 General of
the Rules for Naval Ships. The location of this limit can usually
be found in the ship’s stability information or drawing listed
on the C11(N).
1.1.12 The complete
C11(N) should be verified against arrangements at every Special Survey.
1.1.13 Where repairs
or modifications are carried out to existing appliances, a suitable
test is to be carried out to ensure watertightness or weathertightness
as appropriate.
1.1.14 The ship’s
draughts are to be recorded on the survey checklist Form 2113 (N), see
Ch 24 Appendix 5 Form 2113(N). Where they are
in excess of the design draught, the LR Naval liaison office is to
be advised.
