3.2.2 The Surveyor
is to examine the ship afloat in light condition internally and externally,
for so far as necessary in order to satisfy himself as to the efficient
condition of the hull structure.
3.2.3 Should
examination afloat give rise to doubts as to the condition of the
underwater structure or of tanks and cofferdam spaces, it may be necessary
for the Surveyor to require the ship to be dry-docked or placed on
a slipway for a more detailed inspection.
3.2.4 When the
ship is placed in dry dock or on a slipway, the Surveyor is to examine
the shell plating, the sternframe, rudder(s), etc. and attention is
to be given to those underwater parts of the ship particularly liable
to deterioration due to excessive corrosion or to damage by contact
with other vessels, quay walls or from causes such as chafing, touching
or lying on the ground and to any undue unfairness of bottom plating,
especially in transversely framed ships.
3.2.5 The Surveyor is to be satisfied as to the efficient condition of the
following, where applicable:
-
Hatchways with beams
and covers, deck houses and companionways together with any closing
appliances.
-
Scuppers and sanitary discharges so far as practicable.
- Bulwarks and guard rails.
-
Wheelhouse elevation
arrangements.
3.2.6 The Surveyor
is to examine the steering arrangements. The various parts of the
auxiliary steering gear are to be assembled to ascertain that the
gear is in good and workable condition. Auxiliary steering gear of
the mechanically driven type is to be examined and tested to demonstrate
that, if the power for the main steering gear fails, the auxiliary
gear can be put into operation immediately.
3.2.7 Where rod and chain steering gear is fitted, attention is to be paid to all
parts of rod and chain gears. All pins are to be examined and the chain in the vicinity
of the blocks is to be cleaned and examined for wear and tear. Any length of chain so
worn that its mean diameter at its most worn part is reduced by 12 per cent or more from
its Rule diameter, is to be renewed. All replacements of chains are to be subjected, at
a recognised Proving Establishment, to the proof tests required for short link cables by
Ch 10 Equipment for Mooring and Anchoring of the Rules for the Manufacture, Testing and Certification of Materials, July 2022,
and the certificates are to be produced. It is recommended that, in addition, a breaking
test be applied to these chains.
3.2.8 It is recommended
that repaired chains be tested by the repairers and a certificate
to that effect produced.
3.2.9 The Surveyor
is to examine and test bow rudder installations when they are an essential
part of the steering arrangement. Opening up the gear may be required
if deemed necessary by the Surveyor in view of the condition or the
testing of the gear.
3.2.10 When chain
cables are ranged, the anchors and cables are to be examined by the
Surveyor.
3.2.11 The Surveyor
is to satisfy himself as to the efficient condition of the fire protection,
detection and extinguishing arrangements so far as applicable.
3.2.12 On tankers
of Type G, C and N Closed and N open with flame screens, see
Pt 4, Ch 4 General Requirements For Tankers Carrying Dangerous Liquids in Bulk, Pt 4, Ch 5 Tankers of Type G and Pt 4, Ch 6 Tankers of Types C and N, pump-rooms, cargo, bunker and vent piping
systems on deck and in pumprooms, pressure/vacuum valves and flame
arresters and the electrical installation are also to be inspected,
including verification of:
-
The efficiency of
any safe type equipment fitted.
-
The insulation resistance.
-
Tests are to be
carried out to demonstrate the effectiveness of earth bonding straps,
where fitted.
Inert gas installations are to be examined in accordance with Pt 1, Ch 3, 16 Inert gas systems.
